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.
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.
You will need to turn the mains of to the control panel, whether at a spur or remove the fuse inside the panel, unplug the leads from the battery inside the panel and also the battery inside the external sounder. This will shut the system down.
During a power outage, some systems begin to beep when the AC power is turned off or turned back on. If your system is beeping, the condition needs to be “acknowledged” through the keypad.
A modern security monitoring system will not function during a power outage unless it has a battery backup power supply. Even that is contingent upon the size of the battery versus the amount of energy used in a specific time period.
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.

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.
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.
Many people assume that you need to get the alarm company to remove a burglar alarm, but it's likely to be a lot cheaper to work directly with an electrician (although make sure you notify the alarm company that the alarm is being removed, so they don't think the alarm is being tampered with!).
The alarm in your home security system is designed to be a deterrent to intruders, as well as alert occupants and draw attention to your home, whether that be from neighbours, passers-by or authorities. Systems will sound for about 5 to 10 minutes, depending on the system, before stopping and automatically re-arming.
Now locate the alarm fuse spur – this is usually located next to the alarm panel. Remove the fuse from inside – by levering open the small compartment in the front of the box, and prizing the fuse out. Your alarm will now have no mains power going to it, and it will be running off the battery only.
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.
Your panel has 2 sources of power: The AC power (where it is plugged into an outlet) and the System backup battery. To fully power down your panel you must disconnect both of these. (Note: Powering down your panel should only be done if it is the last resort.
The most likely reason is that the battery is dead. This means that when the power supply is cut, there is no back up in place. If this is the case you need to have it replaced.
If the standby battery is low, contact your alarm company. A message may appear on the keypad noting a battery fault. Entering a valid user code into the keypad may disarm the system and stop the beeping.
If your car alarm is going off and you are unable to deactivate it, you may need to disconnect the battery to reset the system.
98% of the time an alarm rings during a power cut is because this battery is dead! Therefore when the mains is removed, the main control panel battery can't keep the system running so the external sounder starts ringing to inform you there's a problem.
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.
How do I reset my alarm after a power cut? You shouldn't need to reset your alarm after a power cut. After you've dismissed any alerts and ensured the backup battery is working correctly, your alarm should continue working as normal.
