Technical - Fire Supression Test

[miguez]

Howdy,

 

Is it just me, or during the testing of Fire Supression System, with fire warning sensors group 3 (GR 3), the "FIRE APU" light does not come on? It works for Groups 1 and 2.

 

Thanks,

Nope, it doesn't come on. Probably be fixed down the road.

I don't think it should illuminate, I think this is normal behaviour.

[AlphaOneSix]

That is correct behavior. All five lights when testing groups 1 and 2, but no APU light when testing group 3. The manual will eventually be fixed to reflect this.

Excellent, thanks!

There is no 3rd group of sensors in the APU compartment. Not a bug, it's a feature.

A16, AirTito, Geek question. I assume when you do the test, you are checking the fire/overheat detection elements on the Engine compartments and APU compartments, is that the way it works?

[RvETito]

Yes, you're checking both the sensors (termocouples) and their wiring. If a sensor or it's wire has poor conductivity, the group it belongs to will not pass the test and it's light will not illuminate. You need to inspect all the 3 sensors in that group, regardless to which compartment it belongs.

cool thanks.
