[SML] Smoke vs Heat vs Rate of Rise detectors

[Riter, Andrew]

The university has said our entire fire alarm system needs to be upgraded.

When designed in the late 90s (opened in 1997), the designers put heat detectors in the venues, but missed the "shared" areas that look like separate rooms on the drawings but actually share the same air (they put smoke detectors in the pit, Front of House Cove, venue light locks, and air return system).

I'd love to take this opportunity to replace a bunch of the smoke detectors with Heat detectors, but I believe there is a difference between Rate of Rise detectors and "set off at x degree level of heat" detectors.

Can anyone give me a quick primer on these types of heat detectors, and advantages / disadvantages of each?

Thanks everyone.
