How to change ADT battery. At an ADT home security system, there are various devices and accessories, including the main control panel, smoke detectors, door and window sensors, and motion sensors that all have batteries.
When one of the devices has a weak battery, you’ll hear an audible warning beep alert you to the problem. To replace the battery if it’s in the control panel, you may need a different screwdriver such as a key one depending on your type of control panel.
Once you get in and change the battery, however, you can help prevent this from becoming an issue again in the future by changing all of your device’s batteries at once as part of a routine maintenance period.
How to change ADT battery
Change your ADT alarm battery or alarm system battery by first removing the screws on the side of the control panel box. The control panel is usually located in a closet, basement, or utility room.
Next, you need to open the panel with the key provided when your system was installed.
Disconnect battery and remove it using hand tool given by ADT technicians and follow ADT battery replacement procedure given in user’s manual of your security system.
Peripheral Device Battery Change
Step-by-step guides are mentioned below.
Activate the test mode
By entering your access code and then pressing 50, you can access your keyboard from the main control panel.
Open compartment of the battery
First, locate the device with a weak battery. Once you have found it, open it up and expose the battery. You will need a screwdriver for this part, so now might be a good time to grab one.
If your fire alarm or motion detector has started losing power then you will want to rotate it 90 degrees counter-clockwise in order to release it from its mounting ring.
This will take some force. And once it is loose, simply spin it over and open the compartment in which the battery is kept. The exact position of the battery depends on the model.
Install new batteries
Unscrew the device from where it is mounted, and remove any old batteries. Wait 30 seconds before inserting new ones.
Replace both batteries at the same time if your device takes two. Fix the device to its mounting plate with a 90-degree turn counter-clockwise.
Restart the device
Open your Keypad manually and type in your code in the lower-left corner of the keypad. If you’re using a contact ID recognition system, hold your hand there for three to five seconds.
Click “Test,” and if you’ve done everything correctly, the system will respond with “All Clear.” Then, enter your personal identification number one last time and click “Off.”
Control Panel Batteries change
You can open the battery panel
Open up the panel door. In order to do this, you might want to use a flat-head or Robertson screwdriver.
You might just be able to grab hold of it with your fingers instead though, or in some instances, there will be no need for tools at all.
Replacing the battery
Be sure to replace an old battery with one that is exactly the same as the original. In order to remove the old battery, it must first be disconnected from the system.
Attach the wires to the new battery and insert it into the compartment. Snap the door shut.
Recharge batteries and Switch off the test
New batteries do not come fully charged and it takes about eight hours for a battery to charge, even after installing the new one.
The alarm system will be fully operational as soon as you install the battery and stop the test, however. Contact ADT to end this test.
