Fire Alarms in Aircraft

This hasn’t really popped up on TFP Fourms, and I thought a discussion like this should be a thing about Fire Alarms in Aircraft. Usually these are only in big jet liners, and only inform the Pilots, which then take action, but some of them are fun to hear!

My favorite by far is the McDonnell Douglas MD-11 Engine Fire Alarm:

I mean, in the air, these Fire Alarm Systems are way different than on land, but it’s still interesting!

I like the engine fire alarms that older aircraft like the DC-3/4 and C-46 had. There was a red light that would turn on on the dash, indicating which engine, along with a bell located somewhere in the cockpit.
