Carbon Monoxide Detector – Change Batteries

When your Alder CO detector battery gets low, you will be alerted on your panel first. The CO detector itself will not chirp until it gets to critical battery level. If it gets to that point, you will hear a chirp from the detector every 48 seconds until the battery is changed. CO detectors take one CR123A battery. If your sensor’s batteries are low, complete the following steps to replace them:

 

1-iconGo to your touchscreen panel and put your system in test mode. This will prevent any false alarms or tamper alerts while you are changing the battery

 

2-iconGo to your CO detector and twist off the top cover of your sensor

 

3-iconTake out the old battery and replace with one CR123A or DL123A battery

 

4-iconTwist cover back on

 

5-iconSafely dispose of the old battery

 

7-iconBe sure to exit Test Mode on your touchscreen panel when you’re finished
