Wondering how to reset smoke detector after false alarm?

Isn’t it frustrating when the detector’s alarm goes off for no reason and the piercing sound continues without proper reasoning?

Keep reading to learn how to avoid this!

To reset a smoke detector after a false alarm, users should simply hold the TEST/HUSH button on the device’s panel for a few seconds until the alarm stops. Another way to stop the alarm would be to remove the batteries or disconnect the detector from the AC line.

False Alarms On Smoke Detector?

Plenty of things that often do not represent an actual fire can cause your smoke detector to go off.

These events and occurrences are often referred to as false alarms. 

This is when there is no actual fire in your home, but changes in the humidity of the air, temperature, or non-threatening vapor are causing the detector to go off.

Often causes for false alarms on smoke detectors could be one or more of the following:

• Change in the humidity of the air around the smoke detector.
• Vapor is caused by a cooker or a cooking appliance.
• Hardware problems with the detector, such as an insufficient battery charge.
• Too cold or too hot temperatures in the environment (sunlight exposure).

How to Turn OFF Smoke Detector False Alarm?

Most modern smoke detectors have a hush or a test button that practically silences the device.

If the smoke detector has actually detected smoke that is caused by fire, it could still beep even after the fire situation is resolved, and this is when you need to be cautious.

Here are the easiest methods to reset your smoke detector as a result of a false alarm:

Method #1 Use the Test/Hush Button

The easiest method to hush your smoke detector is to use the hardware button installed by the manufacturer.

It is not something unusual, since these buttons are most often used to silence the smoke detector if it is beeping without proper reasoning.

Press and hold the HUSH/TEST button for 10 seconds to silence the alarm!

The hush button is located on the bottom panel of your device. You must grab something to help you reach your smoke detector and therefore press the hush button.

In addition, you need to resolve any sources of vapor or smoke that are not caused by a fire hazard.

Tip: In case the false alarms are too frequent, relocate the detectors somewhere else!

Method #2 Remove the Batteries

An easy way to shut down your smoke detector for as long as you want is to remove the power source, thus the battery.

Nearly all smoke detectors, including those that are included in a household current, do contain a battery in their hardware.

By removing that battery, you will cut the electricity to your smoke detector and prevent it from giving false alarms for as long as you want.

Here’s how to remove the smoke detectors batteries:

1. Grab a chair and position it under the smoke detector to help you reach it.
2. Climb onto the object and make sure that the detector is within your reach.
3. Grab a hold of the bottom smoke detector compartment.
4. Twist the bottom panel counterclockwise to remove the cover.
5. Once the compartment feels loose, pull it out.
6. Expose the batteries inside of your smoke detector and remove them.
7. Re-install the battery of your smoke detector.
8. Check if the issue is fixed.

Note: Some smoke detector batteries are located in a compartment that can be opened by pulling the plastic handle.

Method #3 Reposition the Smoke Detector

In case you want to know how to reset smoke detector after false alarm permanently, here we’ll learn how to do this.

An increased level of humidity in a room can often cause false alarms on your smoke detector. 

To stop the false alarms permanently, the best approach is to relocate the device!

If you’re using a wireless smoke detector, then relocating the device will be an easy task for you.

However for detectors hooked up to the AC (circuit breaker) via wires, relocating might not work, and instead, you’ll need to remove the source of the false alarms.

In case you’re confident that you want to relocate a hardwired detector, here’s how:

How to Move A Hardwired Smoke Detector?

1. Turn off the power to the smoke detector.
2. Give the smoke detector a twist to loosen the bottom panel.
3. Disconnect the alarm from the wiring harness.
4. Loosen the screws of the mounting bracket.
5. Remove the bracket.
6. Disconnect the old harness from the existing wires.
7. Lead the wires into an alternative location.
8. Attach the wiring harness.
9. Reinstall your smoke detector by tracing the steps above back.

In case you encounter a problem while moving the hardwired smoke detector, it’s always best to consult a technician or have one come over to help you out.

How to Avoid Smoke Detector False Alarms?

We all want to avoid false alarms with our smoke detectors. Especially during nighttime, when temperatures are low, the resistance in the device raises, sometimes causing the low-battery beeping and in rare cases the alarm to go off.

Here are some easy solutions to prevent your smoke detector from giving false fire alarms:

• Remove the battery and hold the hush button for 60 seconds.
• Replace the battery inside of your smoke detector every 6 months.
• Replace the device after 10 years have passed since assembly.
• Relocate the smoke detector.

Alert: A smoke detector constantly producing false alarms cannot be relayed on!

The Smoke Detector Is Still Beeping…

If the detector is still beeping even after remounting it and changing its batteries, there is probably a reason for that beeping.

It is best for you to go around your house and make sure that there is no actual smoke caused by the burning of something.

If it was a truly false alarm, the smoke detector would have stopped beeping by now, but if it is still alarming you, you should go around to check your house.

Air out your rooms by opening all windows near the smoke detector and checking if the device would still beep.

Best Places For Smoke Detectors – No More False Alarms!

In case your smoke detector continues to produce false alarms every now and then you can no longer rely on the device.

In such cases, the best approach is to change the positioning of the smoke detector since false alarms can be caused by several well-known sources.

Here’s where to relocate your smoke detector to avoid false alarms:

1. In the bedroom.
2. In front of the bedroom door.
3. On the ceiling in the corridor.
4. On a staircase ceiling.

Avoid installing the smoke detector above cooking appliances, in the bathroom, or in rooms where cigarettes are being smoked.

Position the device where there is no vapor, smoke, or anything that can falsely trigger the alarm.

Alert: In case the smoke detector continues with the false alarms, replace the device!

Quick Recap:

Hence, resetting a smoke detector after a false alarm happens by holding the HUSH/TEST button for about 10 seconds. In case that doesn’t help remove and re-insert the batteries. For hardwired smoke detectors, users might need to disconnect them from the AC line.

Final Thoughts:

Now that we’ve learned how to reset smoke detector after false alarm, we no longer need to have our ears pierced.

It’s important to remember that a smoke detector that constantly emits false alarms is no good and the device has to be replaced if the problem does not go away!
