Opening the Honeywell SiXCOMBO
In this video, Michael from Alarm Grid shows you how to open the Honeywell SiXCOMBO Combination Smoke, Heat, and CO Detector. It is necessary to open the SiXCOMBO before changing the batteries or when accessing the device's inside sticker with information such as its Serial Number.
To open up the Honeywell SiXCOMBO, simply press the device against its back plate, and twist it counter-clockwise. You should then be able to separate the device from its back cover. Once inside, you can perform the necessary task at hand. This could include changing the device batteries. The Honeywell SiXCOMBO uses four (4) lithium CR123A batteries, which are also known as "camera" batteries. They need to be replaced roughly every five (5) years.
You will also find a white sticker with some important information regarding the device. This sticker will have the device's Serial Number, also known as its MAC address. The Serial Number is used when enrolling the device to the Lyric Alarm System. You will also find the device's end of life date. As this is a carbon monoxide sensor, it will stop working for CO detection after a certain period of time. Once that happens, you will need to replace the unit with a new one. You can find the end of life date on the same sticker.
One reason why you will not need to close the device is to perform testing. There are convenient test buttons on the SiXCOMBO that you can access without opening up the sensor. And if you want to test using canned smoke or canned CO gas, then that is also possible without opening the device. Once you are finished, you can close the SiXCOMBO by aligning the sensor against the back plate and then twisting clockwise to secure it into place. The closing process is the same whether the device is mounted on the wall or the ceiling.
