Are there battery powered heat alarms? the answer is yes. the let‘s tell you the main features of heat detector.
Heat detector operation is fairly simple. The detector may activate when ambient temperature reaches a pre-defined point (fixed temperature heat alarm) or when ambient temperature rises by a pre-defined amount, over a prescribed amount of time (rate-of-rise heat alarm). Heat detectors may employ either of these methods, or in some cases, both. Rate-of-rise heat alarms can usually be reset, therefore can be used again. Fixed temperature heat alarms, once they’ve been activated, usually need to be replaced.
Heat detectors especially battery powered heat alarms are usually used in spaces where the environment may predictably cause false alarms for smoke detectors, but where fire is still a real possibility that you want to monitor for. Garages, and kitchens are 2 of the places where battery powered heat alarms are often employed instead of, or in conjunction with, smoke detectors.
There are many battery powered heat alarm I’m aware of that can be used as battery powered. SR-820DHS is one of the battery powered heat alarm that meantime with smoke sensor. more detail please click
