How do I replace my carbon monoxide or combination alarms battery?

Nov 1, 2011

Changing the batteries

We recommend replacing the batteries in all of your alarms at least once a year, or any time the unit indicates the battery is low. The general rule is to replace the batteries when you change your clock for daylight savings time and / or when you switch your clock back. When the battery requires replacement, you must remove the old battery and replace it with the same battery type.

Locating the model number

NOTE: Our alarms have a variety of different battery installation procedures depending on the model number of your alarm.

To locate the model number on the alarm, perform the following steps:

1.  Remove the alarm from the wall or ceiling.

NOTE: Most alarms are attached to a mounting plate and can be removed by turning the alarm counterclockwise.

2.  Locate the model number on the back panel of the alarm.

NOTE: Once the model number and correct battery type have been identified, install the battery using the directions found in the user’s manual
