How To Stop Smoke Alarm From Beeping or Chirping

There we go!

1. Cigarette or burning air:

Smoke alarm beeping no smoke? If smoke detector detects smoke but no flame is present, it sounds beep. This condition usually happens in case of burning cigarette. If you are near a fireplace and smoke detector detects smoke, it may sound beep due to burning air from fireplace chimney or stovepipe.

You may ask how smoke detector could detect burning air? When the heat is too high, some of the particles of the smoke that are not burned leave the room with the air, forming soot. It then absorbs infrared light and heats up. That is the reason why it can detect smoke even when there is no fire.


2. Dust or dirt on photo cell causing false alarms:

A photo cell may be exposed to dust or dirt which may cause false alarms. To prevent this, you should clean the photo cell every now and then.

3. Faulty battery:

A smoke detector requires regular maintenance to keep it working efficiently. One of the most important maintenance tasks is to change the battery every three to five years. Failure to do so will shorten the life of the smoke detector and may even cause it to stop working.

Smoke detectors with replaceable batteries have a small metal tab on the backside which holds the battery in place. In some cases, a screwdriver is needed to remove the tab.

However, if the alarm is not responding to battery change or if it is responding very slowly, it may be due to corrosion or bad connections. In that case, you should check those things first before trying to change the battery.


4. Overloaded system:

In case of overloaded system, the alarm may be caused due to power surge. The smoke alarm may be caused to sound because of a short circuit due to overload. In such a situation, the smoke alarm system will switch from its normal condition to the alarm mode. If you hear a continuous chirping or beeping sound, it means the alarm system is in the alarm mode.

5. Loose connection or wire:

In case of loose connection or wire, the alarm may be caused due to arcing. This is where there is an electrical discharge between two or more points. Arc is harmless and it may occur between any two or more points. However, if it occurs in such a way that it bypasses the smoke detector, it will cause alarm. To prevent this, make sure the wires are snugly connected to the terminal strips.


6. Bad photo cell:

If photo cell is faulty, it may also cause false alarms. Check photo cell by holding the unit upright at a distance and shining a bright flashlight at the photo cell for few seconds. If the alarm sounds, the photo cell is bad. To fix this replace the photo cell with a new one.


7. Bad connections or corrosion:

If the connections or wires are corroded, it could cause false alarm. In case of corrosion, you should clean or replace them immediately.


On the whole, these are the most common reasons why smoke alarm chirps or beeps. But there may be other reasons also. You should check the manual and know all the reasons why your particular model of smoke detector may beep or chirp.

If none of these reasons resolves the problem, you may need to get your smoke detector checked by a professional.
