Stop Leaving Smoke and Carbon Monoxide Unchecked
Detect smoke and carbon monoxide with one unit — photoelectric and electrochemical sensors, an 85-decibel alarm, without multiple wall devices.
Why Is This Safety Monitor Perfect for You?
✔ Two hazards, one device: Photoelectric smoke detection and electrochemical carbon monoxide monitoring work together in one compact housing. Cover two critical household hazards without installing multiple devices.
✔ Loud 85-decibel alarm: When smoke or carbon monoxide is detected, an 85-decibel siren sounds immediately. The alert provides time to evacuate or take action.
✔ Simple setup and status checks: Mount the unit on a wall or ceiling with the included kit, without complex wiring. An extended-service battery supports ongoing operation, while the test switch and visible signal lights make it easy to check the system’s status.
