The last thing you need when you’re trying to maintain a sense of security is for your home alarm system not to work when it’s needed most — when you lose power. So you may be wondering if ADT alarms work without power. Will your investment be worth it when you’ve lost power? Will you be vulnerable to fires and break-ins?
The length of time ADT will function during a power outage depends on the model of your system, but it typically lasts about 24 hours on battery backup after losing power. This is enough time for most people to get home from work or go to an emergency shelter if they need to leave their house.
Before you invest in an ADT security system, it’s crucial to know the system’s capabilities and limitations. In this blog post, we’ll shed light on what to expect when the power is out. So let’s get this show on the road, shall we?
The true test of a reliable security system is how it performs in the event of a power outage. Therefore, if you’re considering getting an ADT security system, several questions may be going through your mind. Will my security system be on when I lose power? How long does ADT work without power? How much time will I have to get my family out of the house if something happens while we’re sleeping?
The answer to these questions depends on your specific system, but in general, you can expect that your security system will be armed when there’s a loss of power.
You see, when your home loses power, you’re not entirely without protection, thanks to ADT’s built-in backup batteries. In a power loss, ADT’s backup system will be activated and continue to monitor your several hours.
In addition, a low-battery signal will be sent to ADT’s customer monitoring center. You’ll also receive a low battery indication on your keypad (e.g. LOW BATT). In some models, the system will also beep continuously until you rectify the low battery problem.
So, how does your ADT security system stay on after a power loss? ADT’s backup batteries will keep the system going for up to 24 hours once they’re activated. This happens because the high-frequency siren and monitoring services take effect when the system is cut from the power. So, whether the power outage is from a natural disaster or a power outage, you’re still covered.
However, to maintain this backup power source, you need to ensure that your backup batteries are always charged and ready to go. At some point, you may also have to replace the backup batteries, which are rechargeable and should last for about five years.
ADT’s customer monitoring center will be contacted if there are any false alarms or emergencies, as well as when your alarm sounds (e.g., a low battery signal). This way, the ADT operator can contact local emergency response teams in case of an immediate threat to life and property.
In other words, you don’t need to panic in the event of an outage—as long as you have backup power.

After a power outage, your ADT system will detect the power outage, and then it may sound a beeping alarm. This is to let you know that your system has detected an interruption in electrical service from the local utility provider.
Some models beep continuously, and it can be loud. To stop the beeping sound, you’ll have to access the control panel. Use your credentials to access the control panel, then click “disarm.” The beeping sound should stop shortly after you’ve disarmed the alarm. However, in some cases, the beeping may continue for a few minutes before stopping.
If you want to reset the system completely, press the “off” button on the keypad twice. However, make sure you use your credentials. Otherwise, the system may lock you out of the panel.
While the beeping sound may be annoying, we don’t recommend turning it off because the beeping sound will alert you if someone enters your garage or home while you’re away. In addition, in a power outage, this beeping sound may also scare away intruders, which you need when you’re in a vulnerable situation.

If you were concerned about how long an ADT security system works without power, then you now have a better idea of how long it will last. The backup duration depends on the security system model. However, typically, the backup batteries will keep the system up and running for about 24 hours. Ensure your backup batteries are fully charged for the best performance.
