The Maintenance and Flight Deck Panels control and provide the user
interface for the FiDS. Should smoke be detected the existing master
caution warning light illuminates both on the glare shield
and
Flight Deck Panel, plus an audible fire warning alerts the flight
crew.
Dispatch reliability is assured using redundant dual-loop smoke
detectors operating independently in each zone and redundant electronic
circuitry. A single switch on the flight deck panel will test the
entire system including: smoke detectors, Halon bottle pressure
indicators, Halon bottles and valve squib directional integrity. |
