[0038] Figure 1 is a schematic illustration of a first embodiment of a suppression system 10 that includes a supply of fire-fighting agent coupled to a preferably fixed nozzle 12 to protect an area or point of risk H in which a source ignition and combustible or flammable materials may be revealed. As shown, the fire-fighting agent supply preferably includes one or more storage tanks or cylinders 14 which contain the fire-fighting agent such as, for example, a chemical agent. Each storage tank cylinder preferably includes a pressurized cylinder assembly 16 configured to pressurize the cylinders 14 for delivery of agent under an operating pressure to the nozzle 12 to quench a fire at hazard point H. The preferred pressurized cylinder assembly 16 includes a bursting device 16a which clamps a rupture disc of a pressurized cylinder 16b containing a pressurized gas such as nitrogen to pressurize the storage tank 14 for delivery of the fire-fighting agent under pressure.
[0039] In order to operate the rupturing device 16a, the system 10 provides automatic actuation and manual operation of the rupturing device 16a to provide the respective manual and automated delivery of the chemical agent in response to the fire to protect the point of risk H. The preferred actuation or rupture assembly or device 16a includes a punch member or pin which is actuated in the rupture disk of pressurized cylinder 16b to release pressurized gas. The puncture pin of the rupturing device 16a can be electrically or pneumatically actuated to crimp the rupturing disk of the pressurized cylinder 16b.
[0040] The actuation device 16 preferably includes an extended actuation device (PAD) 18 for actuating the puncture pin of the mount on the rupture disc. The PAD 18 generally includes an electrically coupled member or rod that is disposed above the punch pin. When an electrical signal is distributed to the PAD 18, the PAD rod is driven directly or indirectly on the punch pin that clamps the rupture disk of the pressurized cylinder 16b. A preferred pressurized cylinder assembly is shown on Form No. F-95143-05 which is attached to Provisional Patent Application No. US 61/704,551 and shows a known rupture device for either automatic electrical or manual pneumatic operation to actuate a pin of puncture. System 10 provides manual and automatic operation of PAD 18. Unlike previous industrial/fire suppression systems that have PADs and rupture discs, preferred system 10 provides manual and electrical operation of PAD 18 as explained in greater detail below. The system 10 can additionally provide one or more remote manual operating stations 5 to manually actuate the system. As is known in the art, manual operating stations 5 can rupture a pressurized gas reservoir, eg nitrogen at 12.41 MPa (1,800 psi), to fill and pressurize an actuation line which, in turn, drives the pin punching the rupture assembly 16a on the rupture disk thereby actuating the system 10.
[0041] Referring to Figure 1, the preferred system includes a preferably centralized controller for manual and automated operation and monitoring of system 10. More specifically, system 10 includes centralized controller or interface control module (ICM) 20. Preferably , a display device 22 which displays information to a user and provides user input to the ICM 20 is coupled to the ICM 20. An audio alarm or speaker 23 can also be coupled to the ICM 20 to provide an audio alert regarding to the system situation 10. More preferably, an audio alarm or resonator is incorporated into the display device housing 22 and configured to operate in a wet environment. Shown in Figure 12 is a representative image of a housing display device having a resonator chamber 19 separated by a resonance disk 19a. The interior of the chamber preferably includes an inclined or oblique surface to define one or more tapered walls 19b of the chamber 19 which leads to an opening 19c that allows any water or moisture to drain while preferably maximizing alarm output. The resonator chamber 19 is preferably located along the housing so that moisture can be drained from the chamber 19 when the housing display device is in its installed position.
[0042] To provide fire detection and actuation of cylinder assemblies 16 and the fire protection system, the ICM 20 additionally includes an input data bus 24 coupled to one or more detection sensors, a data bus of output 26 coupled to preferred PADs 18 and input power supply bus 30 to power the ICM 20 and control and actuation signals as explained in more detail below. Input bus 24 preferably provides interconnection of analog and digital devices to ICM 20; and more preferably includes one or more fire detection devices 32 and preferably at least one manual actuation device 34. The fire detection devices 32 of system 10 may include digital and analog devices for various fire detection modes that include: (i) thermal spot detectors 32a to determine when the surrounding air exceeds a set temperature, (ii) linear detection wire 32b which carries a detection signal from two wires which are contacted by a separating insulating material which melts in the presence of a fire, (iii) optical sensors 32c that differentiate between open flames and hydrocarbon signatures, and (iv) a linear pressure detector 32d in which the pressure of an air line increases in the presence of sufficient heat. Examples of detection devices are shown and described in Form No. F-201158-01 which is attached to Provisional Patent Application No. 61/704,551. The manual actuation device 34 is preferably a manual push button which sends an actuation signal to the ICM 20 for issuing an electrical actuation signal across the PAD 18 of the pressurized cylinder assembly 16. Accordingly, the preferred system provides manual system actuation via an electrical signal to the PAD. Together, the manual actuation and detection devices 32, 34 define a system 10 detection circuit for either automatic or manual detection of a fire event.
[0043] The devices 32, 34 of the input bus 24 may be interconnected by two or more interconnected connecting cables which may include one or more sections of linear sensing wire 32b. The cables are preferably connected by connectors 25. The connection cable from the input bus 24 is coupled to the ICM. The connecting cables of the input and output buses 24, 26 preferably define closed electrical circuits with the ICM 20. Accordingly, a bus may include one or more branch terminators, for example, at the end of a linear sensing wire. Additionally, the sensing circuit may include a line element end that terminates the farthest end of the input bus, for example, and monitors the sensing circuit of system 10. The sensing devices 32, 34 may be digital devices. for direct communication with the ICM as seen in Figure 1. Alternatively, the sensing devices can be analog devices that are coupled to one or more sensing modules 36 for preferential digital communication with the ICM as schematically shown in Figure 1A.
[0044] Again, referring to Figure 1, the ICM 20 is preferably a programmable controller having a microprocessor or microchip. The ICM preferably receives input signals on input bus 24 from sensing devices 32 for processing and where appropriate, generates an actuation signal to the PAD along output bus 26. In addition, the processor is preferably configured to receive signals of each of the input and output buses to determine the status of the system and its various components. More specifically, the ICM can include internal circuitry to detect the status of the input bus, ie, in a normal state, ground state, either if there is an open circuit or if there is a signal for manual release.
[0045] It is schematically shown in Figure 2 the ICM 20 and its internal components coupled to the detection devices 32, 34 along the input data bus 24 and to the PAD 18 along the output data bus 26. In one mode of the ICM 20, the internal components preferably include a microprocessor 40 coupled to the internal circuit 42 having a first portion 42a coupled to the input data bus 24, a second portion 42b coupled to the output data bus 26, a third portion 42c for output. to audio and/or display devices 22, 23 and a fourth portion 42d of internal circuitry 42 coupled to power rail 30 for receiving power from the power supply.
[0046] In a preferred aspect of the system, the ICM 20 and its internal components are configured to monitor the status of the input data bus and sensing devices 32, 34. More specifically, the ICM 20 and its internal components can be configured to determine if the input data bus 24 and associated components have experienced a fault condition due to environmental conditions such as vibration, moisture, or wear. In addition, the internal components of the ICM 20 can be configured with a monitoring circuit in its internal circuit to discern whether the input data bus 24 and its associated devices 32, 34 are any one of: (i) normal state; (ii) an automated or captured detection state and/or (si) a manual release detection state (manual actuation). In addition, the internal circuitry provides a dead band or unused voltage/resistance band for discerning a sensed or automated detection of a sensing device 32 or a manual release sensing of a manually operated actuating device 34.
[0047] Referring to Figure 2, the first portion 42a of the internal circuitry of the ICM 20 partly or fully defines the preferred failure detection circuit 44 in combination with the microprocessor 40 for the input bus 24 and associated components 32 .34. Shown in Figure 3 is a preferred monitoring circuit 44 for the first portion 42a of the inner circuit. The monitoring circuit 44 includes a first resistor R34, a first inductor L5, a mini-DIN connector. J9, a second inductor L7 and a second resistor R50 coupled to ground. Input bus 24 is coupled to mini-DIN J9 on pins 4 and 2. Upon detecting a fault, a pickup current, preferably about 200 microamps (200 μA) is sent through the first resistor R34, the first inductor L5, pin from outside 4 of the mini-DIN via input bus 24 and its devices 32, 34 and backward via mini-DIN J9 on pin 2, via the second inductor L,7 and via the second resistor R50. The microprocessor 40 evaluates the voltage across the second resistor R50 to determine if there is a fault in the input bus 24 and associates the devices. If it is determined that there is a voltage across the second resistor R50 then there is no fault. If there is no voltage across the second resistor R50 then there is a fault. To determine whether or not the fault is a ground fault, i.e. wire in contact with the vehicle chassis or an open circuit, the microprocessor 40 evaluates the voltage at each of the first terminal T1 and the second terminal T2 of the circuit of monitoring. From the voltage differential, the microprocessor 50 determines a resistance value across terminals T1, T2 which define the state of the detection circuit defined by the input bus 24 and its associated devices 32, 34. In a particular embodiment, if the state of detection circuit 24, 32, 34 is defined by the following resistance values (ohms), measured at T1, T2: (i) 350 to 500 ohms and 700 to 10,000 ohms = normal state; (ii) 0 to 350 ohms = an automated or sensed detection state; (iii) 500 to 700 ohms = a manual release detection state (manual actuation) and (iv) greater than (>) 10,000 ohms = an open circuit. Accordingly, the resistance range from 350 to 500 ohms defines a non-state or deadband for the monitoring circuit 44 to create a gap between the manual or captured sensing resistance values so that the system can distinguish between the two States. The preferred open circuit range greater than 10,000 ohms is defined by a preferred total system wire length and resistance that provides an equivalent resistance of about ohms. Accordingly, the open circuit range can be alternatively configured as long as it accounts for the equivalent resistance of the system. The pickup current is preferably drawn from power bus 30. If system 10 is a vehicle fire suppression system, in order to properly detect a ground fault state, earth is a power supply coupled to the bus. which is preferably referenced or grounded to the vehicle chassis.
[0048] Referring to Figure 1A and the alternative system embodiment 10' which has detection modules 36 arranged between the detection devices 32, 34 and the ICM 20, the detection modules 36 can be configured with internal circuitry that communicates with the ICM to detect a fault state in the detection circuit defined by the input data bus 24 and associated devices 32, 34. Shown in Figure 4 is a schematic illustration of the internal components of one embodiment of a detection module 36 The detection modules 36 preferably include their own microprocessor 50 and associated internal circuit 52. Internal circuit 52 preferably includes a first portion 52 in communication with the ICM 20 via input bus 24. Additionally, the internal circuit has a second portion 52b in communication with one or more of the sensing devices 32, 34. In addition, the second portion 52b of the internal circuitry preferably includes a circuitry. A monitoring device that works in conjunction with the processor detection modules 50 to detect a fault within the input data buses and associated detection devices 32, 34. More preferably, the monitoring circuit is configured as the monitoring circuit 44 previously described and shown in Figure 3 with microprocessor 50 that measures and processes voltages across sensing resistor 50 and terminal ends T1, T2 to determine the state of the sensing circuit. The feedback or detected condition of the fault detection circuit, as defined by the resistance detected in the detection resistor R50, can be communicated from the detection modules 36 to the ICM 20 over input 24 to display to the operator on the display device 22.
[0049] Again, referring to Figure 1, the output bus 26 and the actuation devices or PADs 18 in combination with the ICM 20 preferably define the system release circuit 10. As on the detection side, it is desirable to detect faults and more particularly ground faults in the release circuit which can arise due to environmental conditions such as vibration, moisture or wear. In one embodiment of the system, actuating devices or PADs 18 are coupled to output bus 26 for direct communication with the ICM. Accordingly, the internal circuitry of the preferred ICM can detect the status of the actuating device, eg ground fault.
[0050] Again, referring to Figure 2, there is shown a schematic illustration of the ICM 20 which includes its microprocessor 40 and associated internal circuitry having a second portion 42b in communication with the PADs 18 of the system 10 over the data bus. output 26. To provide ground fault detection in the release circuit defined by output bus 26 and PADs 18, the second portion 42b of the internal circuit defines, in part or completely, a ground fault monitoring circuit.
[0051] A preferred ground fault detection circuit 60 for the system release circuit 10 is shown in Figure 3A. The ground fault detection circuit 60 preferably includes a first resistor R31, a first diode D16, a connector mini-DIN J10, a second diode D26 and a third diode D28 in series with the second diode D26 and coupled to ground. Output bus 26 is coupled to mini-DIN J10 on pins 1 and 2. Upon initiating ground fault detection, a pickup current, preferably from power source bus 30 is initiated by processor 40 applying a differential voltage across the first resistor R31. In one embodiment, the initiating voltage ("Pullup_Enable") is equivalent to a reference voltage set by an A/D converter that reads the voltage ("PAD_Detect") at terminal PD1 by processor 40, which detects a PAD 18 of the system. The initiated current flows through resistor R31 and the first diode D16, through mini-DIN J10 on pin 1, through PAD(s) 18, again into the monitoring circuit through pin 2 of mini-DIN J10, then through the second and third diodes D26, D28 for grounding circuit. If there is no ground fault in the release circuit defined by output bus 26 and PAD(s) 18, current will flow through the first and third diodes D26, 28 and as a result, a voltage of a few hundred millivolts is detectable on pin 1 of the mini-DIN J10. Accordingly, the microprocessor 40 of the ICM 20 is preferably configured to monitor the voltage on pin 1 of the mini-DIN J10. When the microprocessor 40 of the ICM 20 determines that there is only background noise voltage and substantially no voltage on pin 1 due to lack of current flow in the first and second diodes D26, D28, the ground fault detection circuit 60 and ICM may indicate a ground fault in the system release circuit 10. In one aspect of the preferred ground fault detection circuit 60 for a vehicle suppression system, the power source providing the pickup current is preferably grounded or referenced to the vehicle chassis. Accordingly, a ground fault condition is defined by a wire from the PAD 18 that contacts the vehicle chassis so that current flowing through the ground fault detection circuit 60 travels through the chassis instead of the first and the second diodes D26, D28 due to the fact that current flowing through the chassis or ground is the path of least resistance.
[0052] Instead of coupling the PADs 18 for direct communication with the ICM 20, a release module can couple the devices of PAD 18 to the ICM 20. Referring to Figure 1A and the alternative system modality 10' that has modules of release modules 70 arranged between the detection devices 32, 34 and the ICM 20, the release modules 70 can be configured with internal circuitry that communicates with the ICM to detect a ground fault in the release circuit defined by the data bus. output 24 and associated actuation devices 18. Preferred release module 70 may couple a single PAD 18 to the ICM 20 or alternatively couple multiple PADs 18 to the ICM. Accordingly, the preferred release module 70 can be used to expand the protection capability of the system by making it easy to add storage tanks and pressurized cylinder assemblies to protect the hazard point or to protect additional hazardous areas.
[0053] In addition, the release module 70 may be configured with a ground fault monitoring circuit, such as, for example, the ground fault detection circuit 60 previously described to determine whether any PAD 18 coupled to the release module release 70 has a ground fault. Shown in Figure 5 is a schematic illustration of the internal components of one embodiment of a release module 70. The release module 70 preferably includes its own microprocessor 72 and associated internal circuitry 74. The internal circuitry 74 preferably includes a first portion 74a in communication with the ICM 20 via the output data bus 26. Additionally, the internal circuitry has a second portion 74b in communication with one or more of the actuating devices or PADs 18. In addition, the second portion 74b of the internal circuit preferably includes a monitoring circuit that works in conjunction with the release module processor 72 to detect a ground fault within the output data bus 26 and the associated actuation devices 18. monitoring is configured as monitoring circuit 60, previously described and shown in Fi Figure 3A, with the microprocessor 50 measuring and processing the voltages on pin 1 of the mini-DIN J10 to determine the state of the release circuit. The feedback or situation detected from the ground fault detection circuit 60 can be communicated from the release module 70 to the ICM 20 over the output bus 26 for display to the operator on display device 22.
[0054] Preferred detection and release modules 36, 70 include the internal circuitry so as to be individually identifiable or solvable by the ICM 20 for communication and/or system programming. In addition, the release module can be configured to define a desired sequence or pattern of actuation to actuate the PADs coupled to the release module. Consequently, in a particular aspect, the release module is configured to selectively provide fire suppression devices that include up to actuate up to approximately ten actuation devices or PADs. The preferred release module includes internal circuitry that provides sufficient current, preferably 3 Amps at 24 volts, to supply enough power to actuate the multiple actuating devices or PADs. In addition, the preferred ICM internal circuitry can detect the status of the actuating device or PAD, for example, to determine if there is a ground fault.
[0055] Systems 10 include multiple storage tanks 14 and pressurized cylinder assemblies 16 for their actuation. System 10 is preferably configured with the plurality of pressurized cylinder assemblies daisy-chained in series, with the release circuit configured to electrically actuate each pressurized cylinder assembly 16 in the chain. To solve the current requirements for such a configuration, the preferred suppression system 10 includes an actuation circuit to provide high current to electrically actuate more than one cylinder assembly 16, and, more preferably, more than four cylinder assemblies. pressurized dro 16 interconnected along the output bus 26, which define the system release circuit 10. The actuation circuit preferably actuates five pressurized cylinder assemblies in series, and more preferably actuates up to ten (10) and up to more preferably more than ten pressurized cylinder assemblies 16 in series. Generally, the preferred high current circuit includes a capacitor that stores current during an unactuated situation of system 10, and discharges the stored current preferably as a current pulse to actuate more than four PADs 18 and more preferably up to ten PADs 18. The performance of the PADs can be simultaneous or alternatively sequential. The high current actuation circuit preferably provides 3 Amps at 24 Volts to actuate PADs 18 of the system 10 release circuit. Alternatively, or in addition, the actuation circuit preferably supplies 3 Amps at 40 Volts to actuate PADs 18 of the system release circuit 10.
[0056] The actuation circuit 80 may additionally include a short circuit protection circuit, as is known in the art to monitor, control and/or limit the release of the preferred stored voltage so that the actuation current pulse is high enough to actuate pressurized cylinder assemblies 16; still low enough to allow the use of output bus 26 connection cable that has a length of 76.2 m (250 ft) or more. Minimizing the current pulse through the 26 output bus allows the use of lower gauge wire of interconnector cable lengths of 76.2 m (250 ft) or more. The actuation circuit may additionally include a monitoring circuit to monitor the magnitude of the current pulse.
[0057] Again, each PAD 18 is preferably configured to receive a pulse of current that drives its stem member on the actuator pin of the rupture device 16a to rupture the rupture disk of the pressurized cylinder 16b. The current pulse has a pulse duration of approximately 10 m. In addition, the current pulse preferably defines a magnitude based on the number of actuating devices or PADs coupled to the actuating circuit. More preferably, the actuation circuit is configured with a pulse current magnitude of approximately 3 Amps DC for actuation of more than four PADs and, more preferably, five PADs of the system release circuit 10. The five PADs 18 preferably define a connected series of actuation devices that define a total load on the actuation circuit of approximately 9 Ohms. To supply the pulse current, the preferred actuation circuit includes a current source in the form of a release capacitor, charged to a voltage sufficient to supply sufficient current, ie, 3 Amps, over at least two current pulses. In a particular modality the release capacitor is charged at 40 Volts before the discharge of the 3 Amps of current pulse. The number of PADs or load can be greater than five, as the current magnitude pulse is proportionally and more preferably increasingly high, along with a sufficient increase in the load voltage of the source capacitor to supply the current. required over at least two current pulses.
[0058] Referring again to Figure 3A, shown is an exemplary actuation circuit 80 that overlaps or is coupled to a portion of the ground fault detection circuit 60. The actuation circuit 80 includes a release capacitor C35, which serves as a current source for the release circuit of system 10. The release capacitor C35 preferably has a storage capacity of approximately 3300 microfarad (μF), which is preferably charged at 40 Volts by an external power source. Alternatively, the C35 release capacitor can be charged by an internal source, such as, for example, a supercapacitor, i.e., double-layer electric capacitor (EDLC) or a vehicle battery, via a release signal from the detection circuit. from the system to the preferred 40 volts.
[0059] Referring again to Figure 3A, the actuation circuit 80 additionally includes the mini-DIN J10 for outputting the preferred actuating current pulse through the output bus 26 for each of the PADs 18 of the system 10. Formed between the C35 release capacitor and the mini-DIN J10 is a current limiting circuit that preferentially limits the actuating current pulse to no more than 3 Amps. The current limiting circuit includes a first resistor R52 for receiving a release signal ("PAD_Release") from the microprocessor of the ICM 20 or the release module 70. Consequently, the actuation circuit 80 can be incorporated into the internal circuitry of the ICM 20 or in a release module 70. When the microcontroller gives the command to release, the “PAD_Release” line is pulled from ground to Vdc (3.3 Volts). This turns transistor Q12 on so as to saturate it (Vce < 100 mV) and release voltage C35 drops across R43 and R51. This causes a source to electronically switch the voltage (-Vgs) in transistor Q10 large enough so as to drive from the source to the drain and conduct current. But as the current from source to drain builds from zero, it produces a voltage across resistor R40 in proportion to the same. As the source current increases, transistor Q11 starts to turn on, due to the fact that its base emitter junction is connected across resistor R40, and the emitter for base voltage is approximately 0.7 V. When transistor Q11 turns on, the collector current starts to flow and this raises the voltage across the electronic switch of transistor Q10 with respect to ground, which lowers the electronic switch to the source voltage |-Vgs|, which leads to a reduction in conductivity from the source down to the drain. The output current has a ceiling of approximately 0.7 V/0.18 Q, which is 3.9 A. The “ceiling” value varies inversely, relative to resistor R40.
[0060] The ability to interconnect and expand system components with a central controller over one or more input and output bus lines provides fire suppression systems of varying complexity. In a particular embodiment shown schematically in Figure 6, system 100 includes a controller 120, an interface display 122, a first input bus 124 with at least one fire detection device 132 and, more preferably, at least three fire detectors. heat point 132a, 132b, 132c, and a linear wire detector 132d; however, it should be understood that the number or type of 132 devices could be varied. The first input bus 124 further preferably includes at least one manual actuation device 134 and, more preferably, at least two manual actuation devices 134a, 134b. System 100 further includes an output bus 124 with at least one actuation device and, more preferably, two PADs 118, each coupled to a pressurized cylinder assembly 116 for discharging a firefighting agent.
[0061] Another modality of the fire suppression system can be configured with at least two incoming bus lines that can protect more than one point of risk. Shown schematically in Figure 7 is system 210 which includes a controller 220, an interface display 222, a first input bus 224a and at least a second input bus 224b, wherein each input bus has a plurality of sensing devices. 232 and manual actuation devices 234. In one aspect of the preferred system 210, the first and second input buses 224a, 224b are configured to respectively protect the first hazard point H1 and at least the second hazard point H2 . In one aspect, the first and second risk points can define different zones, areas or occupations of a vehicle that is protected. System 210 further includes an output bus 226 with a plurality of actuation devices 205, 218 and, more preferably, a plurality of PADs 218, each coupled to a pressurized cylinder assembly 216 for discharging a fire-fighting agent to protection from the first point of hazard H1 and at least from the second point of hazard 2. Consequently, two or more input busbars provide a method to configure the preferred fire suppression system to protect separate hazard points that may have detection and detection requirements. /or acting differently to protect individual risk points.
[0062] Shown schematically in Figure 8 is another form of fire suppression system 310 that incorporates an input bus 324 and an output bus 326, wherein each bus includes respectively one or more release and detection modules , as previously described. System 310 includes a controller or ICM 320, an interface display 322, an input bus 324 having a plurality of sensing devices 332 and/or manual actuation devices 334 interconnected by one or more sensing modules 336 to the ICM 320. The system 310 preferably additionally includes one or more actuating devices 305, 318 and, more preferably, a plurality of PADs 318 interconnected by one or more release modules 370 to the ICM 320.
[0063] The microprocessors in each of the individual detection modules 336 can be separately programmed to configure the detection parameters for the detection device(s) 332 associated with the detection module 336. In another preferred configuration of the detection system suppression 310, separate detection module and device combinations 336, 332 can be configured or programmed to provide fire detection for different risk points that require different detection parameters. In another preferred configuration of suppression system 310, separate detection module and device combinations 336, 332 can be configured or programmed to provide fire detection for different hazard points H1, H2 that require different detection parameters. In another preferred configuration of suppression system 310, the separate release module and actuation device combinations 370, 318 can be configured or programmed to provide fire detection for different hazard points H1, H2 that require different suppression parameters, for example, pattern or sequence of performance. Consequently, a preferred fire suppression system 310 with programmable modules336, 370 provides another arrangement for protecting separate hazard points that may have varying or different detection and/or actuation requirements to solve a fire at individual hazard points. .
[0064] In order to configure a preferred fire suppression system to protect one or more points of risk, the system can be programmed. Referring to Figure 1, the ICM 20 may include an input device, i.e. a toggle switch, or alternatively the ICM may be coupled to a separate user interface for program input, such as, for example, one or more attached display devices 22. Alternatively, the ICM may include wireless communication capabilities, a USB or other port 41, as seen in Figure 2, for connection to a computer, external media or other input device through which a program ,system history, custom settings or firmware can be entered, uploaded or downloaded. In a preferred mode, the ICM can be configured to program the actuation or detection devices 32, 34 and/or modules 36, 70 respectively arranged on the input and output buses. In another aspect, the ICM 20 may include or be coupled to one or more canbus or relay modules 43 for communication with a subsystem of a vehicle, for example, vehicle electronics using J1939 Communication Protocol or an engine compartment for start, for example, shutting down the vehicle in the event of a fire. Transmissions can be scheduled based on the status of the ICM 20, the detection module or the status of the release module. Consequently, example device programming, for example, can configure threshold levels, time delays, patterns and discharge sequences, vehicle parameters and systems, and/or other fire suppression system parameters to provide custom detection and actuation for a particular risk point. Consequently, custom programming of the detection device can provide protection from variable and multiple risk points.
[0065] As described, preferred systems include a display interface to monitor, operate and preferably program the ICM and/or the components, i.e. modules/devices, arranged along the input and output buses. In a particular aspect, the display provides visual indication of the status of the input and output buses which include, for example, indication of: a normal state, a ground state, an open circuit, a manual release. Furthermore, in another aspect, the preferred display is coupled to the ICM to provide operational and programming input. For example, in display devices 22a, 22b, 22c of Figures 9A and 9B, display 22a includes visual indicators and/or visual displays 27a that are coupled to user input devices. As shown, display devices 22a, 22b, 22c may include, for example, push buttons 27b, toggle switches, and/or directional buttons 27c in order to scroll, select, edit, reset and/or enter, etc. operating parameters of the system and its components. In a particular aspect, the interface display includes a manual actuation button 34' for sending an actuation signal to the ICM 20 to transmit a corresponding manual actuation signal to the actuation device or PAD 18 on the output bus 26. The interface display preferably additionally includes a silence button 27d to silence the alarm for a defined period of time, eg two hours before the alarm again notifies the system staff of an unresolved problem. In a particular aspect, the visual indicators of the interface display include LEDs 2e that indicate the status of system components that use, for example, a binary indicator, i.e., on-off. Alternatively, the LEDs can use a color scheme to indicate the status of a system component, ie green - normal status, yellow - fault, red - detection/alarm condition. Shown in Figure 9C is another embodiment of an LED display 27e, together with toggle switch 29, which can be used to enable and identify sensing devices, time delays and/or power supplies. Additionally, or alternatively, the interface display 27a of Figure 9A may use text and/or dynamic or static images to visually indicate the status of the system. For example, the display can use photos or icons as visual indicators.
[0066] In Figures 9D and 9E, exemplary modalities of a user interface display 522, 522' are shown that have two push button toggle switches 529a, 529b in which each push of the button enables or programs a function different depending on the situation of the system. In a preferred embodiment, the first button 529a is preferably configured for manual actuation of one or more of the pressurized cylinder assemblies 16 for the delivery of the fire-fighting agent from the storage tanks 14. so 529 preferably immediately activates the system release circuit for preferential instantaneous discharge of the fire-fighting agent into the hazardous area that is protected. Therefore, the first 529a button is shown as labeled “PUSH to activate”. First button 529a preferably additionally includes a visual LED indicator 527a, which flashes, pulses or flickers for a particular duration and/or frequency to indicate the status of the system. For example, after manual actuation by pressing the first button 529, the LED indicator 527a is configured to indicate that the system is in a post-release or post-discharge state by pulsing, preferably at a frequency of one pulse. every ten seconds or another set frequency.
[0067] When a fire detection device 32 communicates with the ICM 20 signaling the detection of a fire, the LED indicator 527a is preferably configured with the ICM 20 to pulse to visually indicate a detection by the operator of the vehicle or system of a fire and countdown a period of time from detection to release the agent, that is, a release time delay. In a preferred embodiment, LED indicator 527a may be configured to pulse at a first frequency for a first portion of the release time delay and a second frequency for a second portion of the time delay, thereby indicating a system alarm condition. For example, LED indicator 527a may pulse at a rate of twice per second for the first portion of the time delay until, for example, the remainder or second portion of the time delay is five seconds until automatic release. Throughout the second portion of the time delay, for example the final five seconds, the LED indicator 527a pulses, for example, at four times a second. Upon expiration of the time delay, the release circuit acts to release the agent, LED indicator 527a, can indicate the release of the system by remaining constant for a period of time such as ten seconds. After the agent is released, the 527a LED indicator indicates an after-discharge mode by pulsing at the corresponding frequency, for example, pulsing once every ten seconds. Therefore, the LED indicator 527a provides a visual indicator of the various states of the system, for example, alarm or fire detection condition, discharge condition, and post-discharge condition. As described above, the system may include an alarm or loudspeaker 23 coupled to the controller of the ICM 20 to provide an audible indicator or signal of the status of the system. Preferably, the audible signal pulses at the same frequency as the pulse of LED indicator 527a to provide an audible signal of the status of the corresponding system.
[0068] Since the release time delay sequence is initiated after a fire detection signal from a fire detection device 32, the second push button toggle switch 529b is preferably configured to reset the release time delay. As a release time delay reset, pressing the second push button 529b resets the countdown to release, which thereby provides additional time before release and, more preferably, a range between an additional 5 and 15 seconds before release. Controller 20 can be configured to allow a limited number of time delay resets. Alternatively, the system can be configured to allow an infinite amount of time delay resets. A push of the second toggle button 529b can also be preferably configured to silence alarm 23 after a fault condition. Therefore, the second button 529b is shown with “HOLD MUTE FAIL TO RESET”. The second push button toggle switch 529b is preferably additionally configured to program or set the controller and release circuit with the release time delay. Thus, as shown, the second tightening knob 529b is labeled “RELEASE DELAY”. The second button 529b places the system in a preferred schedule or isolated condition before scheduling or setting a time delay or other maintenance for the control system. In a preferred aspect, press and hold the second push button 529b for a period of time, such as 10 seconds, to at least partially isolate the ICM 20 from the release circuit so that the detection circuit cannot initiate a release, but allow manual actuation of the release circuit and continued monitoring throughout the detection circuit. In a preferred aspect, second pushbutton 529b sets, sets, or schedules the release time delay by the duration that pushbutton 529b is pressed. Once the ICM 20 is in an isolated condition, continued depressing and holding the second button 529b for a duration of time programs, preferably, the release time delay. The length of the release time delay is preferably indicated by the number of pulses of a second LED indication 527b associated with the second push button 529b. For example, pressing the second push button 529b so that the second LED indicator 527b pulses three times, sets the release time delay for five seconds, and pressing the second push button 529b so that the second LED indicator 527b pulse five times for the fifteen-second delay. Therefore, the release delay time can be programmed for any increase or length of time and, in addition, be indicated by the LED indicator or other indicator to represent the time delay intervals for agent release. Once the release time delay is set, the second push button 529b can be pressed and held to bring the ICM 20 into a normal condition. As shown in Figures 9D and 9E, LED indicators 527a, 527b may be a part of or incorporated into the associated push button 529a, 529b of user interface 522, 522’. Alternatively or additionally, the user interface, as seen for example in Figure 9D, may include additional LED indicators 527c, 527d to indicate the release of extinction or discharge or system situation, eg detection condition or isolated condition .
[0069] As described, the components and, more particularly, the input bus devices are preferably interconnected by wire or cable and connectors 25, as seen, for example, in Figure 1. In a particular system modality, the cable connection drives control, power, data and/or pickup signals between the sensing devices and the ICM. A preferred 25' connector is provided to interconnect segments of the connecting cable to define a main power bus for use by input bus devices. A particular embodiment of a connector 25' is substantially T-shaped, having a first end 25'a, a second end 25'b and an intermediate connector end 25'c extending between the first and second ends. The preferred connector includes at least one, and more preferably four, inner wire(s) extending from the first end 25'a to the intermediate connector 25'c and to the second end 25' B. With the connector's first end 25'a coupled to an electrical signal that defines an operating voltage, the inner wire of the preferred connector 25' has the same voltage at each of its first 25'a, second 25'b, and intermediate end 25' ç. Consequently, the connecting wire coupled to the second end 25'b of the preferred connector 25' receives the same input voltage as provided at the first end 25'a of the connector. In the exemplary embodiments of Figures 10A to 10C, a device such as, for example, a pickup device 32 can engage the connecting intermediate end 25'c so that the device 32 receives the signal at the same voltage as that provided in the first end 25'a of connector 25'. The 25' preferred connector then supplies main bus voltage along the length of the input bus.
[0070] In yet another aspect of system connections, a color scheme is employed to facilitate proper interconnection between system components. For example, as seen in Figure 11, the ICM 20 may include connection ports for the various buses, i.e., input bus 24, output bus 26, power supply bus, etc. to attach one or more connecting cables to the output, input and/or power supplies bus. The ICM 20 may include a color coded face plate to ensure proper connection of connecting cables which have terminal connectors at their ends which may correspondingly or similarly include colored plastic layer connectors for end engagement of the connecting cable. Using one or more color schemes facilitates system installation. In addition, the connecting cables of preferred suppression systems can be reinforced within a harness that distinguishes them from other cables to prevent accidental tapering or disconnection. For example, the cable connection system can be reinforced with a red harness.

Consequently, it is intended that the present invention is not limited to the described embodiments, but that it has the full scope defined by the language of the following claims and equivalents thereof.
