SYSTEM OPERATION
The state of the system is constantly monitored and is displayed to the driver via the protection
panel. The system provides visual and audial indicators to the driver when the state of the
system changes.
NORMAL CONDITION
During normal operating conditions (appropriate system power applied and no fault conditions
present), the protection panel’s system “OK” indicator is illuminated solid green.
FIRE SCENARIO
When a fire sensor detects a fire in the engine compartment, the Protection Panel’s FIRE
ALARM and the DELAY ENGINE STOP indicators illuminate, an audio alarm sounds, and the
HVAC shuts down immediately. Fifteen (15) seconds later the engine automatically shuts down
and the fire extinguisher automatically discharges.
Engine shutdown and extinguisher discharge may be delayed an additional fifteen (15) seconds
by depressing the Protection Panel’s DELAY ENGINE STOP indicator/switch.
The Manual Activation Switch may be activated to immediately discharge the Fire Extinguisher
and shutdown the engine and HVAC.
The system must be reset and the extinguisher removed and replaced in accordance with the
System Reset portion of this manual.
WARNING! THE ENGINE WILL STOP 15 SECONDS AFTER THE FIRE ALARM STARTS.
THE OPERATOR MUST BE PREPARED TO BRING THE VEHICLE TO A SAFE
STOP AS SOON AS THE ALARM SOUNDS. STEERING MAY BECOME
DIFFICULT AFTER ENGINE SHUTDOWN. IF MORE TIME IS REQUIRED, THE
“DELAY ENGINE STOP” SWITCH MAY BE PRESSED AND RELEASED FOR
AN ADDITIONAL 15 SECOND DELAY.
WARNING! THE EXTINGUISHER DISCHARGE MAY CAUSE AN OBSCURING CLOUD
BEHIND AND NEAR THE VEHICLE.
GAS TRACE LEAK (20% LEL) SCENARIO
When a gas sensor detects a trace leak, the Protection Panel’s GAS LEAK indicator illuminates
(blinking).
The system will reset itself and indications will clear when the gas dissipates below the trace
leak threshold.
