Smoke alarms are essential in making sure that we’re safe in the event of a fire, which is why every home should have one. Although many smoke alarms stay quiet on your ceiling, you might end up hearing a constant beeping that can get annoying as time goes on. Many people have no clue what causes it, but there are multiple reasons why your smoke alarm is beeping. If this is something you’re dealing with, read on for the reasons why and what you should do.

Reasons why your smoke alarm keeps beeping

  • It has low battery
    Smoke alarms will usually keep beeping if they have low battery. This noise is your alarm letting you know that the battery needs to be replaced.
  • The battery drawer is open 
    The battery needs to connect to the terminals for it to work, but if the drawer is open, it won’t be able to do this. So, make sure you check that the drawer is closed.
  • The battery pull tab hasn’t been removed 
    After power has been supplied to the smoke alarm, the battery pull tab should be removed.
  • The terminal is blocked 
    For the smoke alarm to work properly, the battery needs to make contact with the terminals. If something is blocking the terminals, such as the battery pull tab, the two won’t be able to connect.
  • It has reached the end of its lifespan 
    The beeping noise might also be the device reaching the end of its lifespan. Smoke alarms will usually last 8-10 years, so if your smoke alarm is more than eight years old, you’ll need to replace it.

What you should do

If you’ve determined the cause of the beeping, it’s important to fix the problem straight away.

Replace your battery 

If the beeping is due to low battery, you’ll need to replace it. This will usually be the case if the alarm continues to beep during the night caused by a drop in room temperature. When replacing the battery, make sure it’s the correct type.

Check the manufacture date

As mentioned, batteries usually last 8-10 years. So, if your battery is over 8 years old, you should think about replacing it since the device will be less effective. To do this, you should have a look at your smoke alarm’s manufacture date, which can likely be found at the back of the device.

Clean your alarm

If you’ve checked your alarm and noticed a lot of dust or dirt, make sure you clean it. You can use a feather duster and even your hairdryer to blow the dust particles away.

Check your alarm’s position

Where your alarm is positioned is usually determined by the type of sensor it has. The beeping noise can be due to the wrong alarm type placed in or near a room with a lot of steam, dust or smoke.
