Wireless Heat Detectors

Some rooms will never tolerate a smoke detector. Garages collect exhaust, attics collect dust and swing forty degrees in a day, kitchens produce steam and smoke as a matter of routine, and a smoke detector in any of them generates false alarms until someone disables it. A heat detector covers those spaces by watching temperature instead, so the protection actually stays in service.

Two sensing methods are usually combined in one device. A fixed temperature element alarms when the air reaches a set point, commonly 135 degrees Fahrenheit. A rate-of-rise element alarms when the temperature climbs faster than a set rate, typically about 15 degrees per minute, which catches a fast-developing fire well before the fixed threshold is reached. The 5809SS carries both elements in one device, at 135 degrees Fahrenheit fixed and roughly 15 degrees per minute rate-of-rise. Wireless versions report to the panel over the supervised radio with no wire to run, which is what makes them practical in a detached garage or a finished attic. Worth stating plainly: a heat detector is a property protection device and responds more slowly than smoke detection, so it supplements the required smoke detectors rather than replacing them.
