What is a heat alarm and how does the FA6720-R heat alarm work?

General

23 April 2026

A heat alarm detects rapid rises in temperature rather than smoke particles. The FA6720-R uses a thermistor sensor that triggers when ambient temperature reaches between 54 and 65 degrees Celsius. This makes heat alarms ideal for kitchens, garages and utility rooms where cooking fumes, steam or dust would cause a smoke alarm to false alarm.
