9+ Simple Ways to Turn Off a Fire Alarm?

How to Turn Off a Fire Alarm?

The commonly experienced problem among all those who have a fire alarm is a false smoke alarm. We’ve all encountered smoke detectors that set off the alarm. It usually starts after sleeping.

The beeping starts for no reason and startles you out of your restless sleep. And when you feel that you are sleeping safely, the constant noise starts again. It is fairly enough to enthrall you. The main reason electrical devices die unexpectedly is that people don’t change their batteries often enough. In most sensors you can think of, the signal strength increases when it sees something it is supposed to detect.

However, most smoke detectors are designed to turn off when the current drops. This can be a result of the smoke within the air reducing because the battery discharges. As the battery discharges, the current through the sensor also decreases. So you can get bad results. Many reasons and situations can cause this, but most users don’t know how to turn off the fire alarm. In most cases, a battery issue is the cause, and there is a way to stop the beep. Here are the detailed instructions and steps to turn off the alarm.

How To Turn Off A Fire Alarm?

Remove the battery from your fire alarm and hold down the reset button for at least 20 to 30 seconds. Now reconnect the battery and the fire alarm. It will most likely beep once as proof that it is working, then it should stop.

Reasons For The Fire Alarm To Turn On By Itself:

Reasons For The Fire Alarm To Turn On By Itself

There may not be many reasons for a fire alarm to beep on its own; there might hardly be a few reasons, which are,

  • The Battery Might Be Low On Charge.
  • Too Close To Steamy Or Hot Areas.
  • Volatile Organic Compounds.
  • Dirt Could Cause Alarm Beeping.

These are the most common reasons causing a fire alarm to go off on its own; let us discuss them all briefly to be safe from such incidents.

1. The Battery Might Be Low On Charge:

The Battery Might Be Low On Charge

There are many kinds of fire alarms, but hardwired and stand-alone are the most used fire alarm systems around the world. Many fire alarms use such a feature, such that it beeps out on its own when the capacity of the battery is low.

Both types of fire alarms go off after every minute or other to alert you about the batteries being weak. This sound could be creepy and may cause you problems, though you can easily solve this issue by replacing the old batteries with new ones.

2. Too Close To Steamy Or Hot Areas:

Too Close To Steamy Or Hot Areas

The most common reason for an alarm to beep would be to get a false warning from a close by steamy or hot place such as a kitchen or bathroom. If alarms are set near the bathrooms, which contain hot showers could cause problems with the alarms and may set them off on their own due to the presence of steam from the showers.

The alarms often go on by themselves due to heavy substances in the air, such as steam and other heavy compounds like smoke. The steam causes the blockage of current in the alarm same as that the smoke does to the alarm. The same goes for the alarms present near the kitchens due to heat and steam caused by cooking or boiling.

If a fire alarm is too close to your kitchen and you don’t want it to go on by itself, then the best bet is to open the doors and windows near the fire alarm. This causes the fire alarm to not receive any smoke or steam from the kitchen and helps the fire alarm not go on on its own.

3. Volatile Organic Compounds:

This is a very less known reason as some years before; the fire alarms were not as sensitive to volatile compounds compared to the new ones. These compounds or chemicals, also called thinners, are most commonly used in paints to keep them wet while they are in their containers, though it helps in reducing the time they dry out on the wall.

Nowadays, fire alarms are made sensitive to such risky and volatile compounds because they are highly inflammable and may cause a fire inside the place they are used. The sensors used in fire alarms in recent times are more tentative to such volatile substances than before for more security. In such a problem, you need to keep the paint containers that have the thinners away from the alarms to prevent them from turning on.

4. Dirt Could cause Alarm Beeping:

As discussed before, the new age fire alarms are made more sensitive to any kind of substance heavier than air. In this case, comes the dirt present in hallways and open rooms. The most common reason for a fire alarm to go off on its own would be dirt and cobwebs, which are found anywhere and everywhere in the world.

The sensors are made of photoelectric and ionization sensors; these are one of the most sensitive detectors used for the betterment of security. These kinds of fire alarms are used to get better results, though they have a flaw which is they are too sensitive to any kind of substance heavier than air.

There may be many ways to fix a beeping fire alarm, though many may be not be used for all the problems, you could try many ways, but before that, you need to be sure that the fire alarm is giving false beeping due to,

  • It is not subjected to direct steam or smoke from showers and kitchens.

In the case of a fire alarm that is turning on by itself, there is a button called the silence button, which is used in such a case where you need to silence the fire alarm as it might be quite a headache to hear.

It can be solved by the silence button used to quiet out the fire alarm to stop it from beeping; this feature or button is most commonly applied to newage or the standalone fire alarm.

2. Resetting The Fire Alarm:

Resetting The Fire Alarm

The easiest and most effective way used to chop up the fire alarm turning on its own would be resetting the fire alarm using the below-given details. As we discussed in the article, there are about two types of majorly used fire alarms: Standalone (DC) models and Hardwired(AC) models.

In common cases or many fire alarms, the resetting button is to be found or is located in the center of the fire alarms’ front side. Let us take it one by one for each of the types of fire alarms and follow the steps given below,

Hardwired (AC) Models:

In the case of a hardwired model, they use a breaker circuit system that can also be used to stop the use of high and continuous alternating current. To stop the fire alarm from beeping, you need to do the steps given below.

  • The first step would be to turn off the breaker directing the alarm circuit and dismount it from the circuit.
  • Next would be to remove the panel cover and remove the batteries.
  • Hold onto the reset button for about 15 to 20 seconds; if the sound from the fire alarm is turned off, then leave the button or hold onto it till the beeping is no more.
  • Then insert new batteries and connect back the circuit breaker after using the steps given.

Standalone (DC) Models:

Almost the same goes for the standalone models, though the difference would be there are circuit breakers, and they could also be wireless and could help you save some electricity from the hassle of wires.

  • Open the standalone fire alarm and remove the batteries from the alarm.
  • Hold the reset button as follows for the Hardwired (AC) models for about 15 to 20 seconds till the beeping or the alarm is turned off.
  • Then you need to add new batteries to the fire alarm and then turn the alarm on; the alarm needs to chirp once to denote that it is turned on, and then needs to stop to confirm there is no issue in the fire alarm.

3. Regular Testing Of The Fire Alarms:

Regular Testing Of The Fire Alarms

For a fire alarm to be in a good state, it needs to be tested on a regular basis of time to make sure it is working properly. The testing is done using a button present on the front of the fire alarm.

The ‘test’ button is held for about 5 to 8 seconds till it makes a beeping noise or the alarm is set off to indicate that the fire alarm is working properly. If there is more than 1, or an interconnected network of fire alarms, then all would go on at the same time; this could be a kind of headache too.

Though, if the result alters or is different from the expected, then the alarm might not be getting electricity from the circuit, so you need to check the circuit breaker. If the alarm does not turn on, then you need to check for a green LED on the alarm; if it is turned on, then the battery is dead or too weak; and if none of the above applies to the fire alarm, then it might be defective.
