sku# 1694SS1S8
Get smoke and CO alerts through your Ring app Why does Ring call this device a "listener"? Because it literally reacts to the sound of an existing smoke or CO alarm's siren. Mount one near each smoke/CO detector in your home, and if an alarm goes off, you'll get an alert through the Ring app on your mobile device, no matter where you are. Requires a Ring Alarm Security Kit and a smoke or CO detector installed.
