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.
The UltraFire ULLH10RF features a sealed 10 year battery and wireless interlink with up to 15 total alarms to alert the whole house of a possible fire emergency. Ideal for kitchens, garages, basements, and lofts.
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).
