Longlife Battery Smoke Alarms

These smoke alarms have sealed-in 10 year lithium batteries, which last the full life of the smoke detector. No battery changing is necessary, no unauthorised removal of the battery and a tamper-proof design feature make these alarms a safe and economic choice. Ideal for landlords and rented properties, these 10 year detectors offer peace of mind and compliance.

Sealed 10 year batteries mean that these alarms meet not only the previous Grade F requirements from BS 5839 Part 6: 2013, but are also suitable for both Grade F2 and F1 installations. Please see our guide to BS 5839-6: 2019 for more information on Grades of alarm.

Sealed 10 Year Smoke Alarms

Sealed 10 Year Smoke Alarms

Sealed smoke alarms contain a longlife lithium battery that supplies power for the entire ten year life of the smoke detector. At the end of the battery life the power supply is interrupted manually to stop the smoke alarm chirping and the alarm is disposed. 10 Year smoke alarms give peace of mind, stop anybody removing the battery for other purposes and avoid the smoke detector being on the ceiling with the battery removed (as happens often when a smoke alarm has false alarmed or is chirping to indicate a low battery state).
