To prevent accidental engine shutdown 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 shutdown (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:
