Quell 9V Q501 Photoelectric Smoke Alarm - Trade Box

The Quell Q501 Smoke Photoelectric smoke alarm offers a sleek low-profile design for DIY installation, and comes with a 9V replaceable battery that should be changed annually. Photoelectric alarms work by aiming a light source (LED) through a sensing chamber to a receiver. When particles enter the chamber, changes to the light pattern are detected by the receiver, which in turn triggers an alarm. Regular maintenance of your smoke alarms can help reduce the probability of nuisance alarms occurring and ensure the longevity of your device. Refer to these handy tips for guidance. Regular Cleaning - Prevent dirt and debris from entering the smoke alarm chamber by regularly cleaning your alarm. Proper Installation - Install smoke alarms in suitable locations, avoiding areas of high airflow, dead air space, or where steam or high humidity may be present. Battery Replacement - Alarms with 9V batteries should have the battery replaced at least once a year.
