We have a ADT PC5508z alarm system installed in our house. It is notactive (i.e., we don't have a contract with ADT) right now. Two daysago, the thing started beeping every few seconds, and by lookingthrough the manual, I figured out that it was a low battery warning.Where in the world is the battery on this thing though? We took thekeypad off and there doesn't appear to be a battery in it anywhere. Themanual talks about replacing the battery every three years or so, butnowhere can I find anything that tells me where the battery is located.I would appreciate any help I can get. I dont' want to call ADT becausewe haven't had one in the last two years, so they probably wouldn'twant to help us.Thank you very much!Angie

That's just the keypad, look for the main box...usually in a closet somewhere. In the main box you will find either a 12v 7amphour sealed lead-acid battery or knowing ADT it will be a 12v 3amphour sealed lead acid battery. Find box, go buy new battery and replace it.| We have a ADT PC5508z alarm system installed in our house. It is not| active (i.e., we don't have a contract with ADT) right now.

I keep waiting for a moderator or an admin at polytechinca or one of the other fake forum sites to issue us a warning.

Not likely.

If someone doesn't know how to change a battery in one of those, they deserve whatever befalls them.

Well, they subscribe to us. We certainly didn't invite them.

Yeah, I guess. I've never used any of those (what I consider ) toys. I just couldn't bring myself to the level of installing something with a battery powered keypad. Kinda like an old wind-up alarm clock or AM radio.

I played with the idea, but I just couldn't bring myself to do it. I did a take over on one, and I had one I picked up when I bought Desert Alarm. Not sure if David installed it or if it was something he took over. He wasn't around to ask.
