Why is My Smoke Alarm Chirpping or Beeping?

As a homeowner, you are naturally concerned about ensuring that you, your family, and your property are safe from fire. The best way to ensure this is by installing smoke alarms to detect smoke and fire as early as possible so that the fire can be put out and people moved to safety. The only drawback with this plan is the smoke alarm beeping or chirping without a cause and disturbing your sleep, alarming your children and pets, and so on.


Smoke alarms are essential to ensure that any fire in your home is detected quickly enough for it to be put out without causing extensive damage to life or property. However, a smoke alarm that keeps beeping when there is no fire can be a major irritant that alarms small children and pets and causes you to lose sleep. If any of the smoke alarms in your home is beeping or chirping at regular intervals you need to take steps to stop this.



1.Need New Batteries

One reason why a smoke alarm beeps regularly or continually is to indicate that the batteries need to be changed. Smoke alarms are powered by batteries that need to be replaced every six months. One way of keeping track of this is to change the batteries at every time change. However, if your smoke alarm beeps even after that it could be because the batteries have not been installed properly. In such cases, you should remove the batteries and reinstall them with care. Most smoke alarms do not work well with rechargeable batteries. So if you have tried using them, you need to replace them with standard batteries to ensure that the smoke alarm stops beeping.


2.Dust and Debris

Smoke alarms also beep when they become covered with dust and debris. A smoke alarm that is covered with cobwebs, spiders, or other small insects can also beep continually. A smoke alarm can be cleaned by using a blower or handheld vacuum used to clean computer keyboards. You can also use a vacuum cleaner and the right attachment to blow the dust and debris off a smoke alarm. This should ensure that the beeping or chirping stops.


There are also some safety reasons to take care of this and a key safety reason was just hinted upon. It has to do with cleaning around fire alarm if it is dirty or before you disconnect it to take care of the battery. There could be a poisonous spider hiding in the alarm or next to it somehow. This spider could be a black widow or another spider you do not want to startle, certainly if you are standing on a stepping stool about 3 feet above the ground. Now this basic task has just become real interesting.


You can knock down any spiders or their webs with a broom before you even put one foot on that stepping stool. Try not to stand right underneath the smoke or fire alarm when doing this; you do not want a black widow to fall on your face or head!


3.Temperature Fluctuations in the Home

Yet another reason for a smoke alarm beeping or chirping intermittently could be temperature fluctuations at home. If you set the thermostat at a very high or low temperature, the smoke alarm detects this and decides to issue an alert. To avoid this, you need to ensure that the thermostat is set at a more moderate temperature.


Another reason why the smoke alarm goes beeps could be if it detects hot air from the kitchen or shower. This can happen when you are cooking a lot of dishes at high heat or somebody opens the bathroom door soon after taking a hot shower. To avoid such false alarms it is best to either move the smoke alarms from near the kitchen or bathroom door or use some other means to ensure that the hot air does not reach the alarm vents.


4.Silent Button was Pushed

Most manufacturers ask you to periodically test the smoke alarm by pressing the test or silent button. When this button is pushed, the smoke alarm should beep. However, it is possible to accidentally push this silent button or test button when cleaning the smoke alarm or its surroundings. If you suspect that this is the case, all you need to do is switch off the circuit breaker to the smoke alarm, detach the smoke alarm, and remove the batteries, and then press the test button for about 30 seconds. You can now replace the batteries and attach the some alarm to the housing. Next switch on the circuit breaker and verify that the smoke alarm no longer beeps.


5.Its Life has Ended

A final reason for a smoke alarm beeping is that it has reached the end of its lifetime. Smoke alarms typically last for between eight and ten years. Remove the smoke alarm and check the date of manufacturing on the back. If it is more than eight years old, you need to replace the smoke alarm as soon as possible.


A smoke alarm is essential to ensure that you and your family are alerted in case of a fire at home. Since this is an essential means of protection, you should ensure that your home has adequate number of smoke alarms installed. This will depend on the size of your home. You can retain the services of a skilled electrician registered with Redbeacon to provide you with advice on the best locations for smoke alarms in your home. As a rule you must install a smoke alarm in every bedroom and in the hallway. However, if you are installing just a single smoke alarm this should be placed in the hallway equidistant from all the bedrooms.

An expert electrician will help you install the smoke alarms properly and ensure that they do not beep unnecessarily. However, you need to take responsibility for maintaining them once the installation is complete. For instance you need to keep track of when the batteries need to be changed by either following a set pattern of changing them when the time changes or marking the correct date on a calendar. You should also ensure that the smoke alarms are cleaned regularly by blowing away all accumulated dirt and debris from its surface.


As a responsible home owner, you need to ensure that all the protective gadgets installed work optimally. A properly installed and working smoke alarm can save lives and property by alerting you to the possibility of a fire. However, a beeping smoke alarm is an inconvenience and can also cause you to ignore a real fire. As such, you need to take a beeping smoke alarm seriously and first investigate the cause. If you are convinced that there is no fire, you need to adopt a step-by-step approach and first change the batteries, clean the alarm, and reset it before deciding to replace it because you may not have to after all.
