FIRE DETECTION SYSTEM
The engine fire detection system is a flame surveillance system installed in the engine
compartment to provide a visual warning to the pilot. Three infrared-sensitive detectors monitor
the compartment.
Normal engine heat will not be sensed by these detectors. One detector monitors the top of the
engine above the combustion chamber housing, a second monitors the upper accessory area, and
a third the lower accessory area. Infrared radiation from a fire (or sunlight) will be sensed by a
detector and will cause a 28-VDC current to be transmitted to the red flashing FIRE warning
light in both cockpits. The fire warning test switch is a four-position rotary switch, located on
the front instrument panel only, which allows the pilot to test the fire warning system. Both
warning lights should be flashing in all three numbered positions, and be off in the OFF position.
The fire warning light cannot be dimmed or reset by pushing and will return to the standby state
when a fire is no longer present.
