Battery Powered Smoke Alarms

Battery Powered Smoke Alarms

Battery operated smoke alarms are the entry-level of fire detection, typically powered by a single 9V PP3 battery or two 1.5V AA batteries – or by sealed longlife lithium cells which do not need replacing for the full lifespan of the smoke detectors. Battery-powered smoke alarms are further divided into ionisation, optical and heat alarms. Ionisation alarms are suitable for landings and optical smoke detectors for bedrooms, living rooms and hallways. Heat alarms are designed to be installed in the kitchen and garage, along with other rooms in which optical or ionisation sensors would suffer false alarms due to dust, fumes, steam, or other contaminants.

Within the battery operated detector range there is a gradual improvement from simple standalone AA-powered smoke detection to thermally enhanced alarms with 10-year sealed batteries which are capable of interlinking with mains-powered alarms via radio frequency. Interlinked smoke alarms have the advantage that if one alarm detects a fire, all other smoke alarms get notified as well and will sound. This is particularly important if, for example, the bedrooms are far removed from the kitchen or if specialist equipment is needed such as strobe lights and vibrating pads for deaf occupants.
