8.2.4 Fire Detection and Suppression
Fire Detection is accomplished using a resistive wire wrapped around each engine.
Changes in resistance occur when the wire is heated, signaling a potential fire. The
ACS’ monitor the fire detection loop for each engine. When a potential fire is
detected, a signal will be sent through the PFD to the Autopilot Control Panel where it
is annunciated by the illumination of the FIRE portion of the left or right FIRE/ARMED
button.
Fire suppression is provided by a single fire suppression canister in each engine
pylon. This canister is controllable by and reports its status to the ACS. Pressing the
FIRE/ARMED button once sends a signal to the ACS to remove fuel and electrical
power from the engine, arms the fire canister and illuminates the green ARMED
portion of the FIRE/ARMED button. A second push of the FIRE/ARMED button
sends a signal to the ACS to activate the ECB associated with the fire canister; this
will discharge the fire canister. Once discharged the fire canister reports its status to
the ACS which in extinguishes the green ARMED indication from the FIRE/ARMED
button
