Why Does My Fire Alarm Keep Going Off?

However, they can be very annoying when they go off repeatedly or randomly. This article will tell you how to fix this problem.

What Is A Fire Alarm System?

A fire alarm system is an automatic device that activates when there is smoke or heat detected inside a building. It sounds an alarm and sends a signal to the local fire department. 

How Do I Know If My Fire Alarm System Is Working Properly?

If your fire alarm system has been installed correctly, it should sound an audible alarm whenever there is smoke or heat inside your building.

You may also hear a siren if there is a gas leak. These alarms are meant to warn everyone in the building about the danger, so they can evacuate quickly.

However, some fire alarm systems do not work properly. They may only activate once every few days, they may keep going off for no reason, or they may even fail to activate at all.

In any case, you need to check whether your fire alarm system is working properly before calling the fire department.

Here are some signs that indicate that your fire alarm system is malfunctioning:

1) Your fire alarm does not sound at all.

2) The fire alarm does not activate within 30 minutes of detecting smoke or heat.

3) The fire alarm keeps going off even though there is no fire.

4) You cannot turn the fire alarm on or off from the control panel.

5) Your fire alarm system is not connected to the power source.

6) When you press the test button, nothing happens.

7) There is no response from the control panel. For example, pressing the test button does not make the light blink.

8) The emergency lights do not come on automatically.

How Can I Stop My Fire Alarm From Continually Going Off?

Fix 1 – Check the batteries in your fire alarm system.

The first thing you should do is to check the batteries in your fire detector. Make sure that the battery terminals are clean and free of corrosion.

Also, make sure that the batteries are fully charged. Replace old batteries with new ones if necessary.

Fix 2 – Clean the contacts in your fire alarm system’s circuit board.

The second step is to clean the contacts in the circuit board. This ensures that the connections between the wires and the contacts are tight.

Use a small screwdriver to loosen the screws holding the circuit board in place. Remove the screws carefully.

Then, use a cotton swab to wipe away any dirt or dust. Finally, replace the screws.

Fix 3 – Test your fire alarm system.

Turn off the power supply to your home. Open the cover of your fire alarm system.

Connect one end of a wire to the positive terminal (+), while connecting the other end to the negative terminal (-).

Ensure that the wire is firmly attached to both terminals. Now, connect the other end of the wire to the test switch. Press the test switch until you feel resistance.

If the test switch works normally, then there is probably something wrong with your fire alarm system. Contact your local fire department for assistance.

Can An Animal Trigger A Fire Alarm?

No. Animals cannot trigger a fire alarm. However, they can damage your fire alarm system. For example, rodents can chew through the wires in your alarm system. 

They can also cause short-circuits, which could lead to fire.


To conclude, your fire alarm may keep going off because of several reasons. These include: faulty wiring, damaged components, or an animal chewing on the wires.

To avoid this situation, always maintain your fire alarm system properly.

This includes replacing batteries regularly, cleaning the contacts in the circuit boards, testing your alarm system, and fixing the faulty parts if necessary.

You can also open windows when cooking and ensure that you close the bathroom door while showering to prevent your alarm from becoming triggered.
