We’ve had the 2Gig system running great for the last 6 months (since we moved in and took over the system). Just today I am getting low battery on all sensors. This is a takeover with the superswitch from an existing hardwired system. I went and looked in the box and noticed that the positive lead to the backup battery (that goes to the existing alarm circuit board) was disconnected, I don’t know how and for how long it had been that way. I placed it back onto the battery and rebooted the control panel. The same low battery alert came back for all sensors about 20 minutes later.
I guess I am going to go out and get a replacement battery. My question is this: What are the proper steps to installing the replacement? unplug AC then battery? vice versa? Plug in battery then the wall AC? I want to ensure it’s done correctly so that these alerts do not come back on.
Thanks for your help.
