The false alarm of smoke detectors is a serious problem. When a fire does not occur, the smoke alarm keeps emitting an alarm. What should we do? Below, the manufacturer of the fire alarm system will explain the reasons and solutions for the false alarm of the smoke alarm

Reason for false alarm 1: Cooking

Solution: Move the position of the alarm. Installing the alarm further away from the cooking area will make the smoke generated by cooking very thin when it reaches the alarm, thereby reducing false alarms. Choose to buy a photoelectric smoke detector. The photoelectric alarm is not very sensitive to small smoke particles, so it will not produce false alarms for smoke particles generated during cooking.

Reason for false alarm 2: The influence of steam or moisture

Solution: Install the alarm device in a location far away from steam and moisture, such as in the corridor of the bathroom. This can solve the problem. However, if the alarm was originally functioning properly but now responds to steam or moisture, the problem may be due to the aging of the alarm. Older alarms become more sensitive and more responsive to steam and moisture. So the occurrence of false alarms may also be that the alarm has exceeded its service life and needs to be replaced.

Reason three for false alarm: Smoke generated by cigarettes

Solution: In general, smoke detectors do not respond to cigarette smoke unless the generated smoke is very thick. For example, many smokers smoking in the same room may cause an alarm. If the alarm is too old, it will respond even if the concentration of smoke is very low. So on the contrary, we can also use this to determine whether the alarm has aged.

Reason 4 for false alarm: Power supply

Solution: When the battery is about to run out, it will also emit a chirping sound every minute (different models may have differences in spacing and sound, but they all have a low battery warning function), and some people may think this is a false alarm. But this kind of sound is very distinguishable because it produces a single, short sound, and it is emitted approximately every minute. If your alarm makes such an intermittent sound, you can replace the battery to see if it can solve the problem.

Reason 5 for false alarm: Dust

If the alarm keeps sounding, it may be due to the accumulation of too much dust inside the alarm. It is time to consider replacing the alarm or cleaning it. When cleaning the alarm, place the end of the vacuum cleaner near the opening around the alarm and vacuum it one by one. In this way, the dust accumulated on the alarm can be completely removed.

Smoke detectors require regular maintenance and inspection, and most false alarms are caused by aging or accumulation of dust in the smoke detectors. If it is for household use, it is recommended to use wireless smoke detectors. Hotels, schools, office buildings, etc. require a professional fire alarm system with professional maintenance personnel.
