To prevent accidental engine shut down and fire extinguisher discharges, each fire control handle is
maintained in the stowed position by four centre springs and a solenoid operated switch.
When a fire warning is received, the Data Acquisition Unit unlocks the solenoid to allow ease of
pulling the handle. To perform a precautionary engine shut down (no fire condition), the handle must
be manually released by depressing the manual override button (front panel behind each handle).
Each fire handle also has four lamps (bulbs) to illuminate each individual handle for fire detection.
When a handle is pulled to the armed position the following events occur:

• Applicable (engine/APU) fuel Shut-Off Valve (SOV) closes.
• Each engine − applicable hydraulic SOV closes.
• Each engine and APU − applicable bleed SOV closes.
• A signal is sent to turn off the applicable Variable Frequency Generators (VFGs).
• A signal is sent to cancel ignition on the applicable engine or APU.
• Redundant commands are sent to ARM the FIDEEX control unit’s discharge circuits.
If the warning persists following the pulling of the handle, the fire will be extinguished by discharging
a fire extinguisher bottle.

To discharge an engine bottle, the handle must be turned fully and held (at least one second) to
overcome the spring force of the handle; counterclockwise (bottle 1) or clockwise (bottle 2). This
action will send redundant commands to discharge the selected fire extinguisher bottle into the
armed zone. When a handle is turned fully in the opposite direction, the remaining bottle will be
discharged.

To discharge the APU bottle, the handle must be turned fully and held (at least one second) to
overcome the spring force of the handle; counterclockwise (bottle 1) or clockwise (bottle 2). This
action will send redundant commands to discharge the selected fire extinguisher bottle into the
armed zone.
To discharge a second extinguisher bottle in the APU, the lockout release pin must be slid to the
opposite position, to allow the handle to be rotated past the centre position. When a handle is
turned fully in the opposite direction, the remaining bottle will be discharged.
