Smoke and CO protection for
Ring Alarm.
Ring Smoke/CO Listener is a smart sound
sensor for Ring Alarm.
It does not sense smoke or CO directly.
Instead, it adds smart functionality to
your existing smoke or CO alarm (or
smoke/CO combo).
When your smoke or CO alarm begins to
sound, the Smoke/CO Listener activates
and Ring Alarm notifies you of the issue,
wherever you are. If your system is
professionally monitored, our monitoring
center is also notified.

Smoke and CO alarms have a finite
lifespan. Check the date on your
alarm and consult the manufacturerJs
instructions to see if it needs replacing.
