With the advancement in technology, smoke alarms have become an important part of our homes. They are designed to detect the presence of smoke and to sound an alarm to warn occupants of a potential fire.

However, sometimes smoke alarms can be annoying, going off when there is no fire. If your smoke alarm is going off frequently or is just time to replace the batteries, you may want to know how to turn it off. Here is a guide on how to turn off your smoke alarm.

What You’ll Need to Turn Off Your Smoke Alarm?

With a smoke alarm that constantly goes off, you won’t need many tools to fix it. The most you’ll need is a new battery or maybe a screwdriver. Here’s a list of every tool you might need to reset the Smoke alarm.

  • Manuals
  • Batteries- which are usually 9 volts
  • A stepladder
  • Your smartphone

Resetting your smoke alarm is one of the easiest household maintenance jobs you can learn. Follow these steps with the items listed above, and you’ll have it done in no time. Consult your owner’s manual or contact the manufacturer if you have any questions or concerns.

How To Turn Off Smoke Alarm?

The steps to turn off a smoke alarm depend on the type of alarm and the situation. If there is an active fire, the priority is to evacuate the premises and call emergency services. In other cases, such as when cooking or if there is a false alarm, taking the following steps will help to turn off the smoke alarm:

1. Press The Reset Button

The first step is to press the reset button on the alarm. This will usually stop the beeping noise. Reset buttons are usually located in the center on the front of the smoke alarm. If your smoke detector is going off because you burned dinner, it might go off a few times until you can press the reset button and air out the room.

Older models might have the reset button in a different location. The main function of the reset button is to reset your alarm simply.

Pressing the reset button does not always stop the smoke detector from going off if it senses smoke in the area. In this case, you will need to remove the battery or check your circuit breaker.

2. Remove the Battery

If the reset button does not work, the next step is removing the battery from the smoke alarm. Once the battery is removed, the alarm cannot sense smoke and will not go off.

To remove the battery, first, locate the battery compartment. This is usually located on the back or side of the smoke alarm. Once you have located the compartment, open it and remove the batteries. If you have a hardwired smoke alarm, there will not be a battery compartment. Instead, you will need to shut off the power at your circuit breaker. 

Consult the user manual before removing the battery from alarms with a sealed-in lithium battery. Doing so could cause damage to the alarm. Also, be vigilant while removing batteries from fire alarm systems as they might burst, and use appropriate safety measures.

3. Check Your Circuit Breaker

If you have hardwired smoke alarms, you need to check your circuit breaker and reset the switch if it has been tripped. To do this, locate your breaker box and the switch that controls your smoke alarm. Once you have found the switch to smoke detectors, flip it to the off position and back on again. This should reset the power and stop the beeping smoke alarm.

Also, check all the breakers in your breaker box to see if any of them have been tripped. If one of them has, reset the switch, and this should restore power to your smoke alarm.

4. Go to Your Fire Control Panel

If you have a fire control panel like a commercial fire alarm system, go to the panel and reset the alarm. To do this, locate the panel and the switch or lever that says “reset.” Once you have found the reset switch, flip it to the off position and back on again. This should stop the beeping noise from your smoke alarm.

Remember not to handle the fire control panel if you’re not the building’s owner. If the whole alarm system is going off, contact the fire department to come to check out the fire control panel.

Different manufacturers have different types of fire control panels. Some might have a key that needs to be turned, while others have a switch or lever.

5. Replace the Smoke Detector

If your smoke detector is more than 10 years old, it might be time to replace it. Even if it’s not beeping, it might not be working properly. The best way to know for sure is to test your smoke detector monthly and replace it every few years.

To test your smoke detector, press the test button on the front of the alarm. This will cause the alarm to sound. You know it’s time to replace your smoke alarm if it doesn’t sound.

Replacing a smoke alarm is easy and only takes a few minutes. You can buy a smoke alarm at most hardware stores. Follow the user manual instructions to install the new smoke alarm.

What Should You Do About a Smoke Alarm If You’re Renting?

In case of a false alarm, you should first try to locate the source of the problem. If you can’t find it, and the alarm continues to go off, you should evacuate the premises immediately. Once everyone is out of the building, call the fire department.

If you determine that the alarm is false, you can try resetting it by pressing the test button. If that doesn’t work, you can disconnect the battery. However, reconnect it as soon as possible if you do this so you will be protected in case of a real fire.

You should also inform your landlord or property manager about the false alarm as soon as possible. They may need to send someone out to inspect the smoke alarm and determine what caused the false alarm.

If you’re renting and you have a smoke alarm that’s not working, you should:

  • Contact your landlord or property manager immediately.
  • You can contact your local council if they don’t fix the problem within a reasonable time.
  • You may also be able to get compensation if you’ve been significantly inconvenienced.

Smoke alarms are an important part of any rental property, so it’s important to know how to deal with them in an emergency. By following the steps above, you can ensure that you and your family stay safe.

When Should You Turn Off Smoke Alarm?

You might need to turn off your smoke alarm for one of the following reasons:

  • Malfunctioning Alarm: If your alarm goes off for no apparent reason, it may malfunction. Try pressing the test button to see if the alarm sounds. If it does, there may be something wrong with the unit, and you should replace it.
  • Cooking: If you’re cooking something likely to produce smoke, such as grilled cheese, you can temporarily turn off the alarm. Just be sure to turn it back on when you’re done cooking.
  • False Alarm: If the alarm goes off and there’s no sign of fire, it may be a false alarm. Try waving a towel near the unit to see if it triggers the alarm. If it does, there may be something wrong with the unit, and you should replace it.
  • In an Emergency: In the event of a fire, you may need to turn off the alarm to prevent it from sounding. Once the fire is out, turn the alarm back on.

Check the manufacturer’s instructions before turning off your fire alarm. Some units cannot be turned off and should be replaced if they sound frequently.


Can You Turn Off A Smoke Detector?

You can turn off a smoke detector by unplugging it or removing the battery. However, we don’t recommend doing this because it puts you and your family at risk in the event of a fire. But, in case of false alarms, you can try the following:

  • If your smoke alarm is beeping due to low batteries, replace the batteries and reset the alarm.
  • If the cause of the false alarm is unclear, gently vacuum the detector to remove any dust or debris that might have set it off. You can also try waving a stick or broom handle in front of the detector to see if that clears the air and stops the beeping.

Why Does My Smoke Alarm Keep Beeping?

There are several reasons why your smoke alarm might keep beeping:

  • The batteries are low and need to be replaced.
  • Something is blocking the sensor, such as dust, spider webs, or cigarette smoke.
  • The alarm is old and needs to be replaced.

Where Is The Silence Button On A Smoke Alarm?

The silence button is usually on the side or front of the smoke alarm. If you can’t find it, consult your user manual. Once you’ve located the button, press and hold it for a few seconds to silence the alarm.

Will Taking The Battery Out Of A Smoke Detector Stop The Beeping?

Yes, taking the battery out of the smoke detector will stop the beeping. However, we don’t recommend doing this because it disables the smoke detector and puts you at risk in the event of a fire. If you need to silence the alarm, press the silence button. If the cause of the false alarm is unclear, call the fire department.

How Do I Test My Smoke Alarm?

Test your smoke alarm monthly by pressing the test button. If it doesn’t sound, replace the battery and retest. It would be best if you also vacuumed around the smoke alarm to keep it free of dust and dirt. At least once a year, hold a smoldering stick of incense near the alarm to test for proper functioning. If it doesn’t sound, replace it.

How Often Should I Replace My Smoke Alarm?

Smoke alarms should be replaced every 10 years. However, if they start to produce false alarms frequently, it’s time to replace them sooner.


With the right knowledge, turning off a smoke alarm should be a breeze. Just remember the steps and take your time. If you are still unsure, there is no shame in asking for help from a professional. Keep your family safe and informed by regularly testing your smoke alarms and knowing how to turn them off properly.
