Your low battery light could be due to either your backup panel battery or a battery from a wireless device.
If your low battery light is due to your backup panel battery, then please check the following to determine the source of the issue.
Has there been a power outage in your area?
If there has been a power outage, there is a good chance that the alarm panel battery will not need to be replaced since it is rechargeable and should recharge itself when the power comes back on. The backup battery should recharge on it's own within 24-48 hours.
Has a breaker been turned off?
If you turned off a breaker due to renovations on-site, simply turn the breaker back on and the battery should recharge itself within 24-48 hours.
Is the transformer plugged in properly?
Please validate that the transformer is firmly plugged into the wall power outlet. If it is, touch the transformer to see if it is warm. If it is cold, it probably means there is a problem with the wall power outlet or the transformer and it will need to be replaced or fixed.
If your low battery light is due to your wireless device, you can change the battery yourself by opening the device and checking what type of battery you have. Batteries for wireless devices can often be purchased at a local hardware store. Be sure to place your system on test before opening your device as this may send a system tampering signal to our monitoring centres.
