: Home Alarm Battery needs replacing...
2009-02-28, 01:50 PM
I've done this before and it worked fine in my previous house but now, I screwed something up. I replaced the battery in my brinks security system (as it indicated low battery and I got the hourly beeps). So I put the new battery in and my displays are totally dead. If I hit a key on the pad, it beeps, but no LCD display. Door chimes, etc don't work either. I tried another battery and the same thing happens. The wires are connected to the right color. Any suggestions? I tried unplugging and replugging the transformer. No luck either.
Perhaps you shorted the leads - check the fuses on the board.

Got a call from my monitoring service and was told that my battery is low and I have to replace it. They want to send their technician in which I know they will charge me more and the service so I decided to go to Electronic store and bought a new battery(same volt but not the same manufacturer). After replacing the battery, I still get the same sound in my alarm system which is, beep every now and then. Any idea what is the problem with my alarm system.
What's the make/model of your system? Are any of your sensors wireless? If so, then it could have been a sensor battery and not the main backup battery. Does the display indicate which battery is the problem? Who is your monitoring service? The more information the better. It's not only the Voltage that needs to be the same on the backup battery. Perhaps you purchased an incorrect replacement? They are usually rated in terms of Amp-Hours, not just Volts.

I jump the gun. the alarm system is ok now. Just waited for 10 minutes and everything is fine. Thank you very much for the early response.

I'm having a problem as well. I had the low battery warning, and the company called me to tell me. So, I replaced the battery and the panels are still dead. I suspect that the transformer plug has failed, and did not charge the battery. Any thoughts for me?

Make / Model known? Also, by panels I assume you mean the keypads.
Should be easy to tell if the transformer is dead. A simple voltmeter should measure between 16.5 - 18 VAC. If you don't have a voltmeter, the heatsink should be warm/hot to the touch inside the panel enclosure. The heatsink is usually a large chunk of metal, although some newer panels and older Paradox panels used switching power supplies that didn't have them.
Make sure there's power at the transformer plug outlet - easily tested with a test light, or if the transformer itself is a bit warm. It could also be some circuitry, not just the transformer itself. Could perhaps be a poor connection of some sort.
The unit should (probably) have performed for a while properly on the battery when you replaced it, so perhaps something else is amiss.

Definitely the transformer. Checked the outlet with a light - good. Checked the new battery - 12.8V. Transformer, cold. Checked the transformer terminals, zero volts. A new transformer is on the way.
DSC keypads, btw. Yes, it functioned with the trouble light on telling me the battery was failing. Of course, the real problem is that the transformer failed, and wasn't charging the battery. So, I wasted my cash on a battery when the real problem was the transformer. I'll request a couple months of service to cover my battery cost...

Just noticed JohnnyG's post about ADT not allowing to do his own replacement...when mine went a couple months ago, they called me with a quote and were going to have a technician out to replace it. I asked if it was something I could do myself and they said sure - in fact they sent me the battery at no cost and it came with instalation instructions...call the 1-800 number - tell them the password and ask for a 10 minute window of downtime - call back once installed to perform a test. It was simple, fast and easy...no problems. That said, that's just about the only positive experiance I've had with them....but that's another story...

My alarm company pays for the batteries.
I bought the system outright, they installed it, I pay a monthly fee for service (~$11 or $12 I think) and they pay for any needed repairs/battery changes.
I really can't complain at all
good deal for a $20 battery replacement every 5 years

The monthly cost I quoted includes monitoring.
I installed my own system using a kit I purchased from the classifieds plus extra sensors picked up at a home show booth. My house was prewired, so it was not difficult.
I bought my first replacement battery from a store that sold central vac and alarm systems. The Source is less expensive.
