Sealed 10 Year Smoke and Heat Alarms

Sealed 10 Year Smoke and Heat Alarms

Sealed 10-year smoke and heat alarms are designed with a long-life lithium battery which supplies the detector with power for the entire 10-year life span of the alarm. Detectors of this nature, are activated when firmly attached to the base plate upon installation. At the end of the detector’s life, the alarm will chirp intermittently in a pattern. To deactivate the alarm at this point, the alarm just simply twists off the base and the unit can now be disposed of responsibly.

Tamper-proof battery smoke and heat alarms ensure peace of mind, eliminates the possibility of the battery being removed, which happens often with the replaceable battery version. Replaceable battery alarms often have their batteries removed when it has produced a false alarm or chirps to indicate a low battery state, and occupants are ultimately left without any fire detection. This cannot occur with sealed battery alarms, as the battery is contained within the alarm and cannot be removed without damaging the alarm itself.
