Changing the SiXCOMBO Batteries

In this video, Michael from Alarm Grid shows you how to change the batteries inside a Honeywell SiXCOMBO Smoke, Heat, and CO Detector for a Honeywell Lyric Alarm System. The Honeywell SiXCOMBO uses four (4) CR123A batteries for power. It is advised that you use lithium batteries, as they will provide a much longer battery life than alkaline batteries. By installing lithium batteries inside your SiXCOMBO device, you should only need to replace the batteries about every five (5) years. When the batteries are low and in need of replacing, a low-battery trouble condition will appear for the associated zones on the Honeywell Lyric System.

Replacing the batteries for the SiXCOMBO is quite simple. First you must open the detector by pressing the SiXCOMBO against its back plate and twisting the sensor counterclockwise to unlock it. You can then separate the sensor from its back plate and gain access to the battery compartment. You can then remove the old batteries. It is recommended that you wait at least ten (10) seconds after removing the old batteries before inserting the new ones. When inserting the new CR123A batteries, you must observe polarity. The positive (+) and negative (-) ends of the batteries should be facing the proper direction as indicated by the SiXCOMBO sensor. Once the new batteries are secure, you can then close the sensor. Properly align the sensor against the back plate, and twist it clockwise so that it locks into place.

In addition to replacing the batteries every few years, the other maintenance you must perform for the SiXCOMBO is testing it regularly. The SiXCOMBO has two (2) test buttons on the front that can be used for testing signal transmissions to the panel. These are perfectly fine for testing the sensor to get an updated Certificate of Alarm (CoA). But if you want to go above and beyond and test the actual functionality of the sensor, then you will need to use canned smoke, a hair dryer on the max setting, and canned CO gas. Remember to always place your system in test mode before testing the SiXCOMBO in any manner. This is very important for preventing false alarms on your system.
