▫️Power for Smoke Alarms

Smoke alarms can be powered by disposable or longlife
batteries or they can be hard-wired into the 240
volt power supply.
Hard-wired smoke alarms (mains powered) also have
back-up batteries. The back-up battery can be a 9 volt
disposable battery, a long-life battery or a constantly
recharging battery. (Check with the manufacturer's
instructions.)

▪️Smoke Alarm

▫️Types of Smoke Alarms

Photo-Electric (Photo-Optical) Smoke Alarms Photo-electric smoke alarms detect larger smoke particles, the visible products of combustion, and are most effective in the case of smouldering fires. They are less likely to cause nuisance alarms when installed
near kitchens or in areas containing combustion heaters or open fires.
