How to Change the Battery in a Brinks Home Security Alarm

Keeping your home secure gives peace of mind, so make sure your security system is up to date and running well by changing out the battery if you know it has been several years since you last replaced it. If your Brinks-brand home security alarm starts beeping, displays the "Trouble" light or was installed more than five years ago, it may be time to change the battery. (Brinks, which is now ADT, recommends changing the battery anytime between three and five years of use, even if the alarm doesn't beep or show the "Trouble" light.) Change the battery on your own Brinks alarm with just a couple of household tools and a few moments' work. Be sure to call the alarm service provider (Step 4) before you pull out the old battery.

Phillips-head or flat-head screwdriver (check the screw on the panel lock door)
Battery (4Ah or 7Ah)
Insulated pliers
