What if I Lose Power?

If I Lose Power, Will My Alarm System Still Work?

How your ADT monitored security system stays on after power loss

If you lose power, your ADT monitored security system will not turn off and leave you vulnerable to a break-in or fire. Your alarm system has a backup battery to prevent it from turning off.

Your monitored security system still works normally when power is off. Both the high-frequency siren and monitoring services can take effect in the event of a power outage, whether it is caused by a natural disaster or damaged power lines. The backup battery for your monitored security system keeps it powered for up to 24 hours after you lose power to maintain your alarm protection.

To maintain this backup power source, you need to keep the backup battery charged as much as possible. When your battery is low, the ADT monitoring center receives a low-battery signal and can alert you to help solve the problem.

At some point, you may also need to replace the backup battery. You can either do this yourself or call an ADT monitoring representative to do it for you. If you choose to replace it yourself, ADT will send you a replacement battery to install. You can find instructions for replacing the backup battery on ADT’s website.
