Alarm systems are often installed by homeowners to protect their homes from potential intruders. Your home may be unprotected temporarily if there is an unexpected power cut. Modern home alarm systems include backup batteries to protect your electricity supply from interruptions during power outages. Some alarm systems, even with backup batteries, may still display error messages after AC power is restored. The system will have to be reset to get rid of the error message.
- Alarm systems are often installed by homeowners to protect their homes from potential intruders.

Find the button labeled “System” and “System Status” on your alarm keypad. To silence the “No AC Power alarm”, press the button two times in rapid succession.
Keep waiting until AC power has been restored to your house. Remove the backup battery from your alarm keypad.
Locate the circuit breaker box by lifting the cover. Flip the breaker to the “Off” position and flip it back after 5 minutes.
The backup battery on the home alarm keypad should be replaced. You can replace your battery with a fresh one if you wish. Many home alarm manufacturers suggest that the backup battery be replaced every 12 to 15 month. If you receive a low battery message, replace it immediately.
You should wait until your AC is back on.
- You should replace the battery whenever you see a low-battery warning on your alarm control panel.
Input your code and press “Off”. To reset your alarm system, enter the user code again and then press the “Off” button the second time.
It is possible that you will need to reprogram the alarm system settings following a reset. To reset security system settings, follow the instructions on your alarm keypad.
There are different instructions depending on the brand or model of your home alarm. To get the correct instructions for your system, please contact the alarm manufacturer.
