26.7 CARGO COMPARTMENT SMOKE
DETECTION SYSTEM
The cargo compartment smoke detector is a
closed assembly housing solid-state electronic
components and a light sensitive detector. The
detector (4, Figure 26-2) is located in the forward
end of the baggage compartment roof. A
protective screen is installed over the detector to
provide protection from items stowed in the
compartment. The instant smoke reduces light
transmission in the baggage compartment 30 to
35% below that of clear air, the detector causes
the CARGO FIRE warning light on the instrument
panel to flash intermittently. For more detailed
description and wiring diagrams, refer to Chapters
96 and 98.
The CARGO FIRE TEST switch provides a means
to test the cargo compartment smoke detection
system.
