I am getting notifications of low battery on my front door and back door. I’m not sure what I am supposed to do. Any advice?
Looks like there are only a few sensors, and all are reporting low battery. Looks like this system may utilize a TAKE-345 takeover module. If that is correct, the battery that is reporting low is the 12VDC brick battery which would be connected to the TAKE battery terminals. This is usually housed in the old metal panel box. If you did not perform the installation yourself, these are typically found in a basement.
12VDC 5ah batteries can be found at hardware/electronics stores. Here is an example.
That did the trick. Thank you.
Make sure that the battery is connected to both the TAKE-345 and the old panel charging circuit. The TAKE will not recharge the battery, so if it is only connected to the TAKE, it will drain again fairly quick.
