Frequently Asked Questions

Can one listener cover multiple alarms?

Since the Alarm Smoke and CO Listener should be placed within 6” of the alarm, it is recommended that each alarm has its own listener.

Is the listener an alarm?

No the listener is not an alarm and cannot detect when smoke or CO is present. It listens for your alarm and notifies you immediately to ensure maximum safety.

How do I know if my alarm is compatible with the Alarm Smoke and CO Listener?

The Alarm Smoke & CO Listener is compatible with smoke and CO alarms that emit the industry standard Temporal T3 (Smoke) and T4 (CO) alarm patterns in accordance with current UL and National Fire Protection Association guidelines.
