To do this, enter your code as if you were disarming your system to reset the panel. Your system will continue to beep every 4-6 hours to remind you that you are running on battery power at which time you will have to re-enter your code to silence until your battery is completely dead.
Battery Backup: Many alarm systems have a backup battery. Look for the backup power source within the control panel or nearby. Disconnecting or removing the backup battery might silence the alarm.
The most common causes of a home alarm beeping are the faulty battery or your battery is getting weak. Most systems will allow to to silence the beeping by pressing the status button on your keypad, disarm your system and immediately disarm or by disarming your system by entering your code.
An ADT Alarm System's low battery beeping can be silenced by pressing the ``OFF'' button or ``#'' button on your keypad.
EMI. Electro magnetic interference. When power drops the magnetic field around the wires collapses and induce a field at the sensor for the alarm. This triggers it on.

This notifies the alarm that you have aknowledged the power cut and, at this point, the alarm is being powered by the back-up battery. If your external alarm siren is ringing during a power cut, then it means your internal alarm battery (inside the main alarm box) needs replacing.
If that power suddenly becomes unavailable, many systems provide backup batteries to keep the keypad and alarm operational. In many cases, this sounds like great news for homeowners. However, it's important to note that many backup batteries only last four to six hours before they need recharging.
Even after the battery has died, the detector maintains a residual charge that will keep the chirp going for at least seven days. To get the device to stop chirping once the battery has been removed, you must drain this residual charge by holding the test button for 15 seconds.
If all is clear, try disarming your system. If you have a touch screen, look for a trouble alert and acknowledge it by pressing that symbol on your keypad. Check the message that is displaying on your keypad. If the smoke detector has a low battery, the beeping may return until the battery is changed.
Power Outage Issues
Simply enter your keypad code and hit Disarm to clear the alert. After power is restored, if beeping still occurs after 24 hours, please use the Live Chat button in the bottom right corner of this page to talk to an agent.
Go to your main control box and disconnect the battery supply, which will stop all beeping and shut your alarm system down. Once power is restored, you can reconnect your battery and your alarm system should work as before.
Hardwired Smoke Alarms
Locate the main breaker panel for your home. Identify which circuit breaker powers your smoke alarms. Each breaker should be labeled, so look for something that says “smoke alarm” or something similar. Turn off the circuit breaker for your smoke alarms.
Most systems will begin beeping or chirping as a result of a total power outage or failure to recharge the system backup battery. For many of our most popular systems, beeping alarms and low battery trouble beeps can be silenced by pressing the [OFF] or [#] buttons from the keypad.
Pressing the “Test/Silence” button on the front of the unit should stop it from beeping or chirping. If this doesn't work, grasp the device and turn it counterclockwise.
Change the batteries
There is always a chance that it's a weak or low battery. In today's connected smart homes, sensors, detectors, and the panel itself, all function on batteries. Alarm beeping is a built-in warning that signals the power is fading, and that a new battery will be required soon.
Your home security system likely has a main source of power, which is a box that is secured to the wall with an outlet. This box is the key to turning off the alarm while there is no electricity. Simply disconnect the box from the outlet by unplugging it.
If the device is equipped with a battery backup, it might be beeping to alert you about the loss of power. In this case, the beeping might continue until power is restored or the battery is exhausted.
Alarm batteries in the panel act as a vital backup in case there is loss of mains power. If fully charged and in working order, a panel battery can keep your alarm working for upto 12 hours without mains power. Batteries in wireless sensors are their only source of power.
Select “Messages/Alerts/Alarms.” This is where you can see all current troubles and alerts. 4. To silence the beeping, either select each alert individually or acknowledge all troubles and alerts by selecting “Acknowledge All.”
Remove the AC power to the home alarm console from the wall directly. Use your console's access key (or another item such as a small screw) to unlock and open the system's backing. Lastly, disconnect at least one of the wires that are attached to the system's main battery, which is blocky and noticeable in most units.
If your power goes out, your system will run on its back-up battery for approximately 4-6 hours. When the power returns, your panel battery should recharge within 24-48 hours.
