The Honeywell SiXCOMBO provides smoke detection, heat detection, and carbon monoxide (CO) detection for a Honeywell Lyric Alarm System. As an all-in-one wireless life-safety sensor, the SiXCOMBO relies on more power than your average sensor. In fact, you will rarely encounter a sensor that uses four (4) lithium CR123A batteries like the SiXCOMBO. Although you shouldn't need to change the batteries too often, it is something that will need to be done about every five (5) years. Knowing how to do it when the need arises will make the process easier.

Complete the following steps to change the batteries for the Honeywell SiXCOMBO:

1. Open the sensor. Press the SiXCOMBO against its back plate. Twist the sensor counter-clockwise to release it from the back cover. You should then be able to pull the sensor off the back plate and access the inside.

2. Remove the old batteries. Take out the four (4) existing batteries inside the sensor. Dispose of them in a safe manner.

3. Apply the new batteries. Insert the four (4) new CR123A batteries into the sensor. Remember to observe polarity and ensure that the positive (+) and negative (-) ends are facing the proper direction based on the indentations on the SiXCOMBO sensor. Make sure the batteries are all tightly secured in their designated locations.

4. Close the sensor. Take the SiXCOMBO, and align it against its back plate. You must position it so that the sensor lays flat against the back cover. Once it is properly aligned, twist the sensor clockwise to lock it into place. The sensor should remember secure whether it is wall-mounted or ceiling-mounted.
