The SITERWELL Hardwired Interconnected Photoelectric Smoke Detector is designed to maximize home safety by allowing up to 12 alarms to be interconnected, ensuring that when one detects smoke, all alarms sound simultaneously with an 85 dB alert. This photoelectric sensor technology responds quickly to smoke from smoldering fires while minimizing false alarms often caused by cooking. The unit includes a 9V backup battery that maintains operation during power outages and signals when the battery is low. Its do not disturb mode can be activated to silence low voltage or fault alerts for up to ten hours, preventing frequent nighttime disturbances. The test/silence button allows for easy weekly testing of all connected alarms at once, while LED indicators provide clear status updates with a steady green light during normal operation and a red light flashing every 40 seconds when active. This smoke detector combines advanced safety features with user-friendly controls to provide dependable fire protection for any home environment.
