3.2.1.1.1 FIRE SUPPRESSION SYSTEM
When code FSS is specified, a fire suppression system shall be furnished. The system is
designed to reduce the risk of injury in high-energy rear impacts by deploying chemicals designed
to suppress the spread of fire or potentially extinguish a fire. By doing so, it provides more time
for occupants to either escape from a crashed vehicle or be removed from the vehicle by outside
persons. The system uses advanced electronics and on-board sensors to measure post-impact
vehicle movement to determine the optimal time for deployment of the fire suppression material.
The system is integrated into the vehicle's structure and electrical architecture.
System Components:
a. Two stainless steel containers that hold the fire suppressant material and gas
generators used to pressurize and deploy the suppressant material.
b. Two manifold assemblies, each with two deployable nozzles, that spray fire
suppressant down onto the ground.
c. An additional manifold, mounted high with two fixed nozzles, that sprays fire
suppressant material up and into the body.
d. The electronic control module (located under the rear seat) contains the rear crash
sensor, the processing computer, and a large electrical capacitor for backup system
power in case vehicle electrical power is lost.
e. Two redundant wiring harnesses run between the control module and the gas
generators. Each harness is armored to protect it during a high-energy crash. The
redundancy allows one to be damaged without impacting the functionality of the system.
f. The manual activation switch is located on the headliner between the sun visors.
System Function: In the event of a very high speed, high-energy rear impact, a system of crash
sensors and high speed electronic processors determines that the system needs to deploy. The
system delays deployment until the ABS wheel sensors indicate the wheels have slowed and the
vehicle is coming to rest. If the vehicle speed sensors have been so damaged in the accident
that they are unable to command deployment, a back-up timer will deploy the system six seconds
after impact.
The fire suppression materials are stored in an unpressurized liquid state. When the deploy
signal is given, two gas generators, similar to the gas generators used in airbags, generate high
pressure gas. Suppressant and surfactant materials are then emitted through a system of
manifolds and nozzles to suppress the fire. Surfactant reduces the surface tension of the liquid
fire suppressant enabling the liquid to spread more quickly and completely. None of the materials
used in the system are hazardous.
The system deploys automatically when a high-speed, high energy impact occurs at the rear of
the vehicle and manually when other situations require fire suppression. 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.
