there are 3 detectors i can only think of 2 off the top of my head, there is a continuous fire wire which detects mainly heat and sets off the sensor if there is a break in the wire caused by melting,, so u may get a false fire indication from a hot start, there is also an infra-red detector which is more accurate as it can be used to detect actual flames,, the third detector is much like the continuos fire wire and only detects heat so again is not as accurate as the infra red.

How would put out a fire on a jumbo jet?
How big of a fire is it? If it's a small fire, like a trash can or something, airliners have handheld fire extinguishers. For an engine fire or a cargo compartment fire, airliners have fixed fire suppression systems--the plane has plumbing, sprinkler heads and tanks of fire extinguishing agent. But those huge fires you see when a plane crashes? Aircraft crash fires are primarily fuel fires--Class B. The best agent is Aqueous Film Forming Foam, or AFFF, which was invented by the US Navy to fight fires on aircraft carriers. It works extremely well.
