About ADT and Power Outages

When it comes to security companies, ADT is often the first name people think of. It’s no surprise, as ADT has been around since 1874. With all those years of experience, it is no surprise their systems are equipped to handle power outages.

Every ADT system comes with a backup battery that should maintain its charge in case of a power outage. Once your system switches to battery power ADT is alerted. When power is restored, there are steps you will need to take in order to restore your system to its normal functionality.

Check Your System Status

When the power comes back on in your house, your ADT alarm may have been affected. Sometimes there is a beeping sound, and sometimes there is a status or code flashing on the control panel. Check the panel for information as the code may give you information on how to proceed.

Locate Your Manual

There are a variety of ADT security systems, and several types of control panels. Each version may have slightly different specifics on how to perform a reset. A manual should have been provided to you when your ADT system was installed. Read your manual for instructions specific to your model.

Note: If you can’t find your manual, you should be able to find it easily online with a quick internet search – but this will not help you find your reset code.

Locate Your ADT Security Reset Code

Within your provided manual, or other ADT paperwork, you will find your reset code. This code will likely be different than the alarm code you use frequently and can change easily. You will need this reset code to complete your ADT system reset using the control panel.

  • Locate your reset code within your manual. Have it with you at the control panel.
  • Enter the reset code. It is very important you enter the code correctly so as to avoid a phone call or home visit.
  • Wait for the system to reboot. This may take a minute.
  • Use your personal Code to disarm the alarm.

If You Type the Wrong Code

If you input the wrong code somehow it is important to remain calm. You will most likely receive an immediate phone call and/or home visit as entering the wrong code registers as a security breach. Simply explain the situation clearly and calmly. This issue occurs more frequently than you might think.

Meanwhile, you can take this time to enter the code correctly. Press the “#” button to restart the process. Now you can correctly enter the reset code.

If You Don’t Have The Reset Code

You can’t reset the system using the control panel without the reset code. Your next option to reset your ADT system is performing a manual reboot by cutting off the power supply.

Resetting Your System To Factory Status

You have forgotten your passcode or for some other reason need to reset the entire system and panel. There are steps you can follow to do so before you need to call a technician.

1. Find And Remove The Power Source To Your ADT Control Panel

Find the power source that connects directly to your ADT control panel. Most models are plugged directly into a wall outlet via a transformer. Typically the transformer is a white, beige or black box-shaped plug. In order to unscrew and unplug your transformer from the wall you will need to use a phillips head screwdriver.

2. Check Battery Status and Disconnect Battery

After you shut off the power source you must disconnect the backup battery. You will see a black wire connecter and red wire connecter attached to the battery. Remove both connectors, first the black wire and then the red wire.

Note: You may need to wiggle the wire connectors slightly in order to disconnect them. Do not use excessive force or yank the connectors. This may cause the wire to break, creating a larger issue.

3. Wait several minutes

Be sure to give the system several minutes without power. Several sources say wait up to 5 minutes before reconnecting the power source. This allows the system to fully reset.

4. Reinsert Battery and Connect Wires to Reconnect

Reverse the process from step 2 by reconnecting the black and red connectors. Then reinsert the transformer in its plug and screw it securely back into the wall. This will reconnect the ADT alarm to its power source.

5. Check Alarm Status

Once the system is powered up, go to your control panel. At this point, the system should be reset to its original state, and you should be able to arm or disarm it accordingly.

Still having Trouble?

You may still be unable to restart your ADT system after a power outage. The next step will be to use the ADT customer support hub to receive personalized support. There are multiple home security systems to choose from. ADT is particularly known to have multiple customer service options including online and telephone support to resolve your reset issue after a power outage.

Concluding Thoughts

After a power outage, the odds are you will have to reset your ADT security system to some degree. The first step is to check your control panel as it may tell you the exact issue. Regardless, you will most likely have to reset your system.

Resetting your ADT system can be done quickly if you have your system reset code that came with your system manual. Otherwise, you will need to reset the system manually by unplugging all power sources and then restoring them. If none of these techniques work, contact ADT. They will help guide you to resetting the system and restoring security to your home.
