How To Turn Off ADT Alarm System Without A Code

Like any other alarm, the ADT alarm system also comes with various sensors that alert whenever it detects an intruder. But there are times when the alarm could turn on accidentally. ADT alarms are loud enough to alert your neighbor. They might call the police on you. This could turn into a big problem if you forgot or lost the code to turn off the alarm

In this case, you will have to rely on other methods to turn off the alarm. This article will go through the ways you can use to turn off ADT alarm system without a code.

How To Disable ADT Alarm System Without a Code

Disabling an ADT alarm system is easier than you think. Depending upon your ADT model, you must learn how to remove the transformer or battery if it’s not working.

Here is how you can disable the ADT alarm system without a code:

1. Removing ADT Command/Pulse Battery

Usually, you will be using the touchscreen to shut down the system by entering the code. But since you don’t have the code, you will have to do it without shutting off the system.

With the help of a screwdriver, unscrew the screw at the center of the panel. After you have unfastened the screw, slide off the touchscreen panel to expose the back of the system. You will find the battery under the plastic clasp and one final screw.

Unfasten the screw and remove the plastic clasp. After this, you will notice that the battery is still connected to the panel by quick-connect. You can remove the battery only after you have disconnected the battery from the quick-connect.

2. Using the ADT Key Fab to Disable the Alarm

You can also disable the ADT security system with the help of the key fab. You must ensure that your system wasn’t installed while the old residents stayed.

Otherwise, you won’t know where the key fab is. To disarm the alarm using the critical fab, all you need to do is to press the “disarm” button.

You might see a shield icon with a slash; your system will be disarmed. Doing this should disarm your alarm; if it does not, you will have to press and hold the “disarm” button for about two seconds. Doing this will finally disarm the alarm.

3. Call ADT

Another thing you can do is try calling ADT to see how they will respond. ADT usually leases the equipment to the contract owner and extends the lease to three years.

If the equipment wasn’t leased to you or you are not the contract owner, you can try calling them to see if they are willing to disable or replace the alarm.

4. Remove the ADT Hardware

Before you remove the ADT hardware, make sure that you let the monitoring service know about this beforehand.

That way, they can ensure that the ADT system alarm does not go off, which might cause many problems.

Once you have permission to remove the alarm, remove the transformer and battery first. When successfully removing them, carefully remove the sensor, control panel, and camera. Before handling the wiring, ensure the breaker switch is turned off.

5. Reset the User Code, Including the ADT System

It could be that the previous owner installed the alarm system, or your contract with ADP ended. Your alarm system will still work, even if ADT does not monitor it.

So you don’t have to worry about resetting the code and the system itself. After resetting the code, you can replace it with anything you like.

Since Honeywell is the primary manufacturer of ADT panels, this method will likely work on most security systems.

Another thing to note is that you will have to disconnect the ADT command panels since they don’t have an installer code which means they can’t be adjusted.

How to Prevent ADT Alarm Triggers in the Future

If you don’t want your ADT alarm to trigger accidentally and cause trouble for everyone involved, you should learn how to prevent this from happening in the future.

To prevent this from happening in the future, you need to follow these steps:

• There shouldn’t be any obstruction around the sensors
• The alarm system should be regularly serviced every year
• Replace the batteries once they are low on power
• Consider investing in pet-friendly motion detectors if you have pets
• Regularly and adequately clean the sensors of the alarm system
• These are some measures you can take if you don’t want your alarm to trigger accidentally in the future.

Final Talk

If your ADT alarm accidentally went off, don’t panic and stay calm. You don’t have to worry about not being able to turn off the ADT alarm even if you don’t have the codes. The methods to turn off the alarm system is relatively easy. Hopefully, with the help of this article, you can figure out how to turn off the alarm.
