How do I know if my smoke alarm is detecting a fire or it simply needs maintenance?

Beeping from your smoke alarm can be frightening at first. However, when you realise that the beeps are slower and that there is no fire around then confusion may occur. When there is a fire that the smoke alarm has detected, the smoke alarm will beep hardly and loudly. Specifically, the usual alarm sounds are random, last for a few seconds and uses a lower-pitched tone noise. But, when a simple maintenance check is needed, the alarm will usually make equal intervals, high-pitched beeps, once every minute.

Why is my smoke alarm beeping?

As mentioned before, there can be a number of different reasons for a smoke detector to beep. Here below are the more common cases where a smoke alarm will begin to continuously beep:

Low battery

Being one of the most common reasons why the smoke alarm will continue to beep is because it needs its battery changed. One beep every minute is the average pattern the system will do to alert you that it is needing battery replacement.

Battery Drawer is Open

A simple mistake of not closing the battery drawer properly can make the alarm beep. This is because the battery and terminals do not contact each other correctly.

Terminal is Obstructed

Likewise, if the battery is not contacting the terminal properly, it will not work and beep. To fix this put the battery in correctly, as well as remove any obstruction from keeping the two touching.

Battery Pull-tab is Kept in the Alarm

Forgetting to remove this is a simple mistake. It should be removed after AC power is connected to the smoke alarm, if not, the alarm will beep.


The smoke alarm can go off/ beep if you have placed the temperature of your place on really high or really low. Temperature fluctuations will trigger the beeping noise of the smoke detector. Similarly, if the smoke alarm is near the kitchen or bathroom at detects smoke (cooking or hot shower), it can beep. Simply moving the smoke alarm away or having ventilation can stop the beeping from happening.

Ended Lifespan

A smoke alarm will alert you when it is about to not work anymore. In turn, replacement of the smoke alarm should occur every 8-10 years.

How do I stop the beeping?

To stop the beeping, commonly replacing the battery is what is needed. If this is the case, it will still beep until you have reset it. Provided below are two different smoke alarm systems and how to stop the beeping noises after replacing the battery:

Battery-powered Smoke Detectors

  1. Firstly, take out the current battery of the smoke alarm
  2. A button called ‘test’ should be there. If so, hold it down for roughly 15 seconds to trigger an alarm sound.
  3. After the short alarm sound has gone off, simply put in a new battery. Ensure that it is in correctly to make final beeping noises. These noises are there to tell you that the battery has been connected correctly.

Electric Smoke Alarms with Battery Backup

  1. Importantly, the first step is to turn off the electricity in your home. To explain, this is to prevent electrocution to occur when working on the smoke detector.
  2. Disconnect the smoke detector from the power cable which plugs to the system. Ensure that you take it off the mounting bracket on the ceiling to complete this step.
  3. Like before, open the smoke alarm and hold down the ‘test’ button after taking out the current battery. After 15 seconds a beeping noise will occur followed by it silencing.
  4. Next, place the new battery in the alarm properly. Once this is completed, reconnect the power cable and position the alarm back onto the mounting bracket. Lastly, turn the power back on and the smoke detector will beep to tell you that it has power and working properly.
