How to Stop the ADT Alarm From Beeping Low Battery

Do you hear a constant beeping sound coming from your ADT alarm? If yes, then it’s time to check on your batteries.

Nothing is more annoying than a low-battery alert that keeps beeping every few minutes. 

Why does my ADT alarm keep beeping?

There are several reasons why your ADT alarm keeps beeping, but the most common reason is due to low batteries.

When the battery runs low, it sends an alert to notify you that it needs replacing.

Another reason could be a faulty or damaged sensor in your system. This can cause false alarms and trigger the beeping sound even if no actual danger exists.

Power surges and electrical outages sometimes cause your alarm to beep continuously. These events can disrupt the electrical current of your alarm system and send false signals to your control panel.

Some ADT systems have a tamper-proof feature that sets off an audible alert when someone tries to open or manipulate it without proper authorization.

In summary, there are various reasons why your ADT alarm may keep beeping; however, checking for low batteries should always be the first step in troubleshooting this problem.

How do I stop the beeping?

If your ADT alarm is beeping due to a low battery, the first step you should take is to locate the control panel. This can usually be found near the main entrance or in a central location within your home.

Once you have located the control panel, you must enter your security code and press “Off” or “Disarm.” If the system continues to beep after disarming it, there may still be an issue with a low battery.

To stop the beeping caused by a low battery, you will need to replace it. You can purchase replacement batteries from most hardware stores or online retailers.

Be sure to follow any instructions provided by ADT for replacing batteries in your specific alarm system model.

After replacing the battery, wait at least 30 seconds before re-arming your system. This allows time for it to reset properly and prevent any false alarms.

If replacing the battery does not stop the beeping, contact ADT customer service for further assistance. Your alarm system must remain in proper working order for optimal security of yourself and your property.

What should I do if my battery is low?

If your ADT alarm is beeping due to low battery, you must first identify which battery needs replacing. Typically, ADT alarms have two batteries – one in the main control panel and another in the wireless sensors.

To determine which battery needs replacement, check if the low-battery indicator light is flashing on your sensors or the main control panel.

If it’s a low-sensor battery, replace it with a fresh one by following manufacturer instructions for your particular model.

On the other hand, if the main control panel battery has run out of juice, unplug your system from AC power before opening up its compartment cover. Then remove and replace this old battery with a new one according to instructions provided by ADT.

Once you’ve replaced either or both batteries as needed, reconnect everything securely and test-run your system again. This should stop any further beeping caused by low batteries.

How often should I replace my batteries?

One of the most important things to remember when maintaining your ADT alarm system is to replace your batteries regularly.

This will help prevent malfunctions or false alarms, which can cause unnecessary stress and anxiety.

The frequency at which you need to replace your batteries largely depends on the type of battery you are using and how much power it consumes over time. Generally speaking, traditional alkaline batteries should be replaced every three years.

However, if you are using lithium-ion batteries, they can last up to five years before needing replacement.

It’s important to note that certain factors, such as extreme temperatures or frequent power outages, may impact the lifespan of your batteries.

Therefore, it’s always best practice to regularly check the status of your battery levels and consult with an ADT technician for advice on when replacement is necessary.

These steps will keep your ADT alarm system working well to protect your home or business.

Can I use rechargeable batteries?

One of the questions that often come up when dealing with an ADT alarm system is whether or not rechargeable batteries can be used.

The answer to this question is yes, but there are a few things to keep in mind before making the switch.

Not all rechargeable batteries are created equal. Rechargeable batteries may have lower voltage output than AA alkaline batteries, so you must ensure they’re compatible with your ADT alarm model.

Even if you find a compatible rechargeable battery with the right voltage output, it’s still important to check with your ADT provider before making any changes.

Depending on your contract with them or warranty terms of service agreement, using non-standard equipment like rechargeables could void certain warranties or leave you liable if anything goes wrong.

If you use rechargeable batteries in your ADT alarm system, remember to schedule maintenance to recharge them.


A low battery in your ADT alarm system can be frustrating and disruptive. However, with the abovementioned steps, you can quickly stop the beeping and ensure your home is always protected.

Remember to check your batteries regularly and replace them as needed to avoid future inconveniences. And if you are ever unsure how to replace or troubleshoot your alarm system, don’t hesitate to contact ADT’s customer support for assistance.
