Why are heat detectors not listed as life safety devices?

Howdy!

I was looking at Edwards’ website (which is cool because links to EST, Vigilant, FireworX, Dukane, and Edwards Signals are all there, like a hub) and I saw that the conventional mechanical heat detectors have “Not a life safety device” printed on them. Does anyone know why? I just thought it was interesting.

Heat detectors are designed to respond to high levels of heat characteristic with a rip-roaring fire. Unfortunately this means the conditions may not be suitable for escaping the fire. Smoke detectors are life safety devices because they go off early enough to give people a chance of escaping the building before it is too late. Therefore, heat detectors are more intended as property protection than life safety.

To add to that there are extremely harmful chemicals released in large fires.

Also here is a blurb from LifeSafety Magazine(by System Sensor) on there use.

@LifeSafety Magazine

There are certain fire-protection applications where smoke detectors are not suitable, such as non-life-safety installations where the environment has too many airborne particulates due to excessive steam, moisture, dust, humidity or temperature, such as in attics, garages, warehouses, storage facilities, elevator machine rooms and electrical closets. Smoke detectors applied in those environments are cost prohibitive from a maintenance standpoint.
