Severe duty equipment
The Fire Suppression System is mounted beneath the vehicle and attached
to the frame above and forward of the fuel tank and rear axle. The Fire
System Control Module is mounted inside the passenger compartment
centered underneath the rear seat cushion. The system is designed to deploy
automatically after sensing a high-speed/high-energy rear end impact.
There is a covered manual activation switch mounted in a console on the
headliner between the visors that can be used by vehicle occupants to
manually deploy the system. The fire suppression system can be
manually deployed anytime the vehicle is in a Key ON or Engine ON
mode by pushing the button underneath the cover. The button can be
accessed three ways:
1. Pushing on the cover will release the cover latch, allowing the door to
swing open and expose the button;
2. The cover can be pulled open;
3. A firm strike on the cover (about 20 lbs of force) will deploy the
system anytime the vehicle is in a Key ON or Engine ON mode.
In the event of a manual deployment, nozzles will deploy to near ground
level and the underbody of the vehicle will be covered with suppressant
fluid. The suppressant contains no hazardous materials (but may cause
minor skin or eye irritation) and can be readily cleaned up by flushing
the underbody with water (or soap and water). Manual deployment
should have no adverse affect on vehicle handling; however, caution
should be exercised in moving the vehicle as ground clearance will be
compromised by the deployed nozzles. Because of reduced ground
clearance, the vehicle should not be driven through an automatic car
wash with nozzles in the deployed condition.
The fire suppression system is a single use system—all major components
will have to be replaced in the event of a manual deployment.
