FIRE DETECTION AND EXTINGUISHING SYSTEM
The fire detection and extinguishing system consists of
three major components: three heat sensitive detectors lo-
cated in each engine accessory compartment; an annunciator
and actuator panel (see Figure 7-4); and a compressed Freon
single shot gas bottle in each engine accessory compartment.
A test function is provided to test the system circuit-
ry.
When the test switch is pushed all lights should illu-
minate, if any light fails to illuminate replace the bulb.
If the green light does not illuminate after replacing the
bulb, replace firing cartridge in fire extinguisher.
Any
other light failure, after replacing bulbs and firing cart-
ridge, indicates malfunction in unit or associated wiring.
