Fire Detection System Installation and Operation Manual MADE IN THE USA
READ THIS MANUAL CAREFULLY AND SAVE FOR FUTURE REFERENCE. KEEP THIS MANUAL WITH THE SYSTEM.
Introduction The fire detection system. It has the ability to monitor pressure switches/IR-Thermal switches/ and other contact type inputs. These inputs will control the indicators on the display to alert a user of service needed or in case of a fire. They also control the engine shutdown relay and one input has its own separate output. This output switches system voltage out if a condition occurs. Read this owner’s manual completely before installation. Failure to read and follow these instructions can result in damage to the unit voiding the warranty.
CAUTION: NO POWER ON/OFF SWITCH IS PROVIDED FOR THIS UNIT. TO FUNCTION AS INTENDED, THE CONTROL PANEL MUST BE CONNECTED TO A CORRECT POWER SOURCE (5 amp or greater), AND FOR MAXIMUM EFFECTIVENESS, BE POWERED AT ALL TIMES A DANGER MAY BE PRESENT. IF POWER IS ON AND LEFT UNATTENDED FOR AN EXTENDED PERIOD OF TIME, BATTERY POWER MAY BE DIMINISHED.
Manual Display Controls / Indicator Fire Detection OK - Green when there is no fire detected or service required Service Required – Orange when pressure has dropped in detector bottle or piston accumulator. Fire – Red when pressure lost or fire detected/occurred.
Display Installation The Control panel should be mounted in a convenient location, preferably where the visual indicators may be readily seen. To install the display, you must first cut a rectangular opening 4 1/8” x 2 1/4”. Secure the display at the four corners with #6 screws.
Wiring the control panel The display has three connectors for external connections and one pink wire for battery back-up. See diagram below for connections. See the table for connector pin outs. FM-US-400018 has an in line fuse on the positive cable.

Function Gnd from display 50 Bar in switch (if 50 Bar is open & 14 Bar is closed then service lights. If 50 Bar & 14 Bar are open then fire lights, siren sounds, relay activation) 5 Bar in switch (if 5 Bar is open & 14 Bar is closed then service lights. If 5 Bar & 14 Bar are open then fire lights, siren sounds, relay activation) Relay Option (if disconnected no relay delay on fire, if connected to system voltage 15 second delay on relay) 14 Bar in switch (if 14 Bar is open & 50 or 5 Bar is closed then service lights. If 14 Bar & 50 or 5 Bar are open then fire lights, siren sounds, relay activation)

Testing Display Mode If no alarm conditions are present, holding either button down for 4 seconds will initiate a self test sequence. During this sequence all LED’s will cycle along with the engine relay and siren.
Engine Relay The engine relay is controlled by the fire system and has (C,NO,NC) dry contacts for multiple wiring options. If the “Fire” light comes on the relay will turn on immediately. If the green wire is connected to system voltage the relay will turn on after 15 seconds. See connector table.) P/N 18136

IR-Thermal Relay This relay has the common tied to system voltage and is normally open. When a ground is present at the IRThermal input the relay closes sending out system voltage. This will activate the relay switch.
Button Operation Either button can be used for each system. When there are no alarm conditions holding either button for 4 seconds will initiate a self test sequence. If the siren is sounding, holding either button in for 1 second will mute the siren for 15 seconds. If the engine relay is activated holding either button will reset the relay for 250mS to signal the bus’s monitoring system. If the green wire is connected to system voltage and the engine relay is activated, holding either button for 5 seconds will cause the relay to reset for 15 seconds allowing the vehicle to start. See connector table. Testing the operation of the fire suppression system: 1. Connect all wires and arm the fire suppression system. Turn on the bus. After the automatic system test runs if everything is connected and the bottles charged to the correct pressure the green “SYSTEM OK” light should be illuminated.
2. Disconnect the connection between the 50 bar pressure switch and the wire harness. This is labeled “EXT PR SW”. The “SERVICE REQUIRED” light will be illuminated. Reconnect after this is verified.
3. Disconnect the connection between the 14 bar pressure switch and the wire harness. This is labeled “DET CYL PR SW”. The “SERVICE REQUIRED” light will be illuminated. Reconnect after this is verified.
4. Disconnect the connections between the 14 bar pressure switch and the 50 bar pressure switch. The “FIRE “light will be illuminated. The siren will sound. The relay will activate (unless the green wire is connected to system voltage. See connector table.). Press Silence reset button for 1 second to silence the alarm. To restart the bus hold the Silence reset button for 4 seconds to reset the 15 second timer.
If system is equipped with the optional 5 bar pressure switch: 1. Disconnect the connection between the 5 bar pressure switch and the wire harness. This is labeled “5 BAR SW”. The “SERVICE REQUIRED” light will be illuminated. Reconnect after this is verified. 2. Disconnect the connections between the 5 bar pressure switch and the 14 bar switch. The “FIRE “light will be illuminated. The siren will sound. The relay will activate (unless the green wire is connected to system voltage. See connector table.). 3. Disconnect the connections between the 14 bar pressure switch, the 50 bar pressure switch and the 5 bar pressure switch. The “FIRE “light will be illuminated. The siren will sound. The relay will activate (unless the green wire is connected to system voltage. See connector table.).
