Follow the AMM Chapter 26 (Fire Protection) procedure with associated warnings and cautions if you are an engineer. If not, leave it to your engineers unless you have a specific FCOM procedure to use it.
It injects a simulated ASD signal so warnings, functions and indications can be checked by BITE test.

Just watch out for the ‘wings fall off’ button. It’s on the same panel. So take your time. :E

On the B-727 anytime you did the fire test with the APU running, you did an APU auto shutdown test.:)
