Before we get to the how, let us first try to understand the why. Do you have any idea what’s making the alarm sound after an issue with power?

Why is the Alarm Beeping After a Power Outage?

Even if your alarm system is hardwired into your house’s electrical circuit, it will have a backup battery.

These have been in place in case a power outage occurs, keeping all households and buildings safe.

Back-up batteries allow your system to protect your home should the main source of electricity for your house ever shut off.

Most often when your alarm beeps persistently, it means that your system is alerting you that its batteries need replacing.

Usually, this happens after the power goes out because your alarm system uses the backup batteries during the power outage.

NOTE: You should replace your smoke alarm batteries every six months, according to the National Fire Protection Association (NFPA).

So, is there a way to fix it on your own?

How To Stop Alarm from Beeping When Power Goes Out? Fix Steps

Whether you’re trying to learn how to stop fire alarm from beeping when the power goes out or any other type of alarm, we got you!

We outlined this guide to be versatile so you can use it across all kinds of alarms.

Step #1: Replace the Batteries of the Alarm

Having extra batteries on hand for power outages isn’t just for fueling flashlights. Instead, it can also be a type of backup when your home alarm loses its juice.

Try replacing the batteries if the power is currently out. To do this:

1. Go up to the alarm and remove the brace or front cover.
2. Then, locate the battery tray of the alarm.
3. Pull it out to unearth the batteries installed in it.
4. Install and place the new fresh pair of batteries.

NOTE: Be sure to turn the power to your alarm system off first before disconnecting it from the ceiling.

You can do this by switching off the circuit breaker for that room on the main electrical panel of your house.

Step #2: Disconnect the Power Supply

If the power is currently out and you do not have extra batteries on hand, then disconnecting the backup battery/power supply is a temporary way to stop your alarm from beeping.

Use a chair or stepladder to reach your smoke alarm and remove the batteries. Or open the backing of the main control panel on your security alarm to access the batteries.

Remember to replace all batteries with fresh ones once the power returns.

NOTE: Removing the batteries in your smoke alarms and home security alarms will temporarily power them down.

This will stop your alarms from going off and end the annoying chirping sound.

Do consider, though, that not all alarms work like this. So, ensure that you’re cutting electricity or power completely flowing through the device.

Step #3: Enabling the Silence Feature

If your alarm is beeping even though there is no emergency, it could be startling and bothersome.

Luckily, most alarms often have a silence feature. This is a feature added to alarms in case of a false alert.

Depending on which alarm system you have, silencing your alarm can be done in several ways:

Enter Your Alarm Code

This will alert your system that you are aware of the need to change the battery. It may continue to beep every few hours as a reminder of what transpired.

Select the Reset or Clear Buttons

Reliant on the model you have, you’d need to press the Reset or the Clear button on your alarm. This is an action that’s like disabling the alarm temporarily.

Press and hold these buttons until the unit gives a signal that it’s about to stop.

Push the Hush or Silence Button

For the newest and most advanced systems, a “hush” or a “silence” button is existent.

This made all alarm owners’ lives easier because it can be turned off by clicking this button.

Step #4: Disarm the System

Another solution to stop your alarm from beeping when the power goes out is to disarm it.

Not sure how you can do so? Follow the outlined steps we have below to safely disarm and reinstall your fire alarm system to stop beeping.

1. Turn the circuit breaker off that’s connected to the alarm in question.
2. Then, remove the fire alarm safely from its ceiling mount.
3. Use compressed air to blow out any dust inside of the alarm.
4. Replace the batteries.
5. Press and hold the reset or test button.
6. Return the fire alarm to its ceiling mount.
7. Restart the breaker to power up your fire alarm.

Once that’s done, you’ve now successfully disarmed the entire security system.

Step #4: Contact Your Service Provider

If you have replaced your alarm’s batteries and you cannot stop the alarm from beeping, it may be an issue with the wiring in your system.

This is especially the case if your system is five years or older and is continuously beeping. This is a sign that it’s time to contact a service provider.

Call your security company or a reputable local electrician to inspect your system. They will perform maintenance if needed or recommend the right replacement if yours is no longer protecting you at its best.

This is a sure way to stop your alarm from beeping when the power goes out but could take time to schedule the home visit.

Step #5: Replace Your Alarm System

If you have followed the initial steps we outlined in this guide and the problem is persistent, then it may be time for a replacement.

All alarm systems have a lifespan of 5 to 10 years. You should replace your alarm system within this timeframe to avoid false triggers and keep your technology current.

To know when to change, you can look at the back of the alarm or the system manual. They will provide information about how often you should replace your alarm system.

Choose easy-to-install wireless alarm systems. Why? Because they can give you the flexibility to place smoke detectors or motion sensors where you desire.

Alternatively, you can also opt for a professional installation by getting in touch with a company that provides home protection you trust.

NOTE: Performing yearly maintenance on your alarm system, like blowing out dust and changing the batteries will expand its life.
