Silence Alarm: Some alarm panels have a dedicated silence or reset button. Check the control panel for any labeled buttons related to silencing or resetting the alarm. Pressing these buttons could stop the ringing.
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.
If you lose power, your ADT monitored security system will not turn off and leave you vulnerable to a break-in or fire. Your alarm system has a backup battery to prevent it from turning off.
Generally, the security cameras will stop working when the power is out, whether it is for recording, motion detecting, or sending push. But the security camera with a battery is an exception, which runs on battery power and will continue to record without electricity.
Disconnect the vehicle's battery for a short period (such as 15 minutes) and then reconnect it. This might reset the system. Be aware that disconnecting the battery may cause the loss of other settings, so refer to your user manual for guidance.
For this reason, all modern alarm systems have a battery backup designed to power the system for 10-24 hours, depending on the complexity of the system and the condition of the battery.
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.
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.

The bell box battery is there for a different reason.

During a power outage, your system will switch to its internal back up battery. The internal backup battery typically lasts 4 to 6 hours. Until the backup battery is depleted, your system will alert you with low battery beeps.
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.
The good news is that most access control systems will have a battery back-up for occasions where mains power is lost. So the battery will takeover in the event of a power outage and there will be continuity and no disruption to normal operations.
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.
