FEODSEW Interlinked Smoke Detector

Interconnected: Photoelectric smoke detector systems utilize radio frequency technology to transmit and receive information about hazards in the home, so when one alarm goes off, all alarms sound, notifying everyone of the emergency
Double Protection: Combination alarms with dual sensors detect both smoke and carbon monoxide hazards in a single unit and provide instant warning with a loud 85 decibel sound.
Accurate, Reliable, and Sensitive 2-in-1 Alarm: The photoelectric smoke sensor and the electrochemical carbon monoxide sensor work independently of each other; detects both fast-burning and slow-burning fires, and notifies you immediately when a dangerous concentration of smoke or carbon monoxide is detected, while minimizing false alarms.
One-Touch Control: Simply press the test/silence button on any alarm to conveniently test or silence the entire interconnected system, which can be connected to multiple devices
Easy to Install and Use: Easily install the alarm with the mounting bracket, no hard wiring required, very easy to install in your home or bedroom, use the included screws to mount it on the wall.
