Quell 240V Photoelectric Wired Interconnect Smoke Alarm with 9V Battery

The Quell Q2300 Series smoke alarms are mains-powered optical detectors equipped with a DC battery back-up, ensuring continuous protection even during power outages. Models Q2300 and Q2300LL support hardwired interconnection with up to 23 compatible units from the Q2300, Q2300LL, Q2300W or Q1300 ranges. Interconnected functionality significantly enhances home safety—when one alarm detects smoke, all connected alarms sound, providing an early warning across the entire home. This feature is especially crucial for alerting occupants in remote rooms or on different floors, offering vital time to respond and escape in an emergency. 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.
