Smoke and Carbon Monoxide Alarm Listener Overview and Installation Guide

Determine Your Third-Party Detector Type

Before installing your Alarm Listener, you will need to know if the third-party detectors in your home are interconnected or battery-powered.

If your detectors are interconnected, that means that you will only need one Alarm Listener for your home; but if they are battery-powered, you will need one Alarm Listener for every third-party detector in your home.

How to Check Your Third-Party Detector Type

Press the test button on any of your detectors. If only that one detector sounds, it's a battery-powered, standalone unit. In that case, you will need one Alarm Listener for every third-party detector in your home. If all of your detectors sound, that means that your third-party detectors are interconnected, so you will only need one Alarm Listener in your home.

Where to Install the Alarm Listener

The Alarm Listener must be mounted within 4 inches of the third-party detector you wish to monitor. If the Alarm Listener is mounted farther away, it will not pick up on the detector’s alarm signal. When finding a place to install the Alarm Listener, keep the following placement guidelines in mind:

• The Alarm Listener must be mounted on the same surface as the detector (ceiling-to-ceiling or wall-to-wall)

• The microphone grate and directional arrow on the Alarm Listener must face the detector

• Use the included mounting card to verify the four-inch distance between the Alarm Listener and detector 

• Avoid mounting near TVs, speakers, or other loud sound sources that may cause interference

How to Mount the Alarm Listener

1. Hold the mounting bracket in place with the arrow pointing toward the detector

2. Use a pencil to mark the drill holes

   1. If mounting on drywall: drill pilot holes using a ¼” drill bit

   2. If mounting on wood or plaster: drill pilot holes using a 1/16” drill bit and gently tap the wall anchors into the pilot holes using a hammer or mallet

3. Hold the mounting bracket in place with its arrow pointing toward the detector and secure it in place using a Phillips head screwdriver and the included screws

Confirm the Mounting Bracket is Installed Correctly

It is critical that the Alarm Listener is installed correctly to ensure that it can listen to your third-party detectors. Before proceeding, confirm that:

• The mounting bracket is on the same surface as the desired detector and is no more than 4 inches away

• The mounting bracket's arrow is pointing toward the detector

Secure the Alarm Listener to the Mounting Bracket

Once you have confirmed that the mounting bracket has been installed correctly, you can attach the Alarm Listener to it.

1. Align the triangles on the mounting bracket and Alarm Listener 

2. Twist the Alarm Listener clockwise until it clicks into place

   1. If the Alarm Listener is not seated correctly, you will see a blinking red light on the device
