Independent smoke alarm false positive reason

What is the false alarm caused by the false alarm of an independent smoke alarm?

1. In the absence of smoke, independent smoke alarms intermittently alarm.

2. When the power is turned on, the independent smoke alarm will ring continuously.

If the newly purchased smoke alarm has the following major causes of false positives, there are two solutions to the effects of cooking, steam, or moisture:

a. Move the position of the alarm, and place the alarm far away from the cooking place will make the smoke generated by cooking become thin when reaching the alarm, thus reducing false alarms. However, this method does not always work, especially when the air flow will bring cooking smoke to the alarm. Therefore, when moving the alarm, be sure to first understand the flow of air.

b, replace the alarm, try to choose a photoelectric independent smoke alarm (there is also an ion independent smoke alarm, the smoke particles are invisible to the human eye is more sensitive). Photoelectric smoke alarms are less sensitive to tiny smoke particles. The visibility of smoke particles and fire smoke particles produced during cooking is different. It is invisible to the human eye. Therefore, false alarms from cooking smoke particles or moisture are very small.

Even though this would make the optoelectronic alarm slower to respond to large fires (more tiny particles produced by the fire), the time difference is very small.

Second, the smoke produced by cigarettes causes false alarms. Since everyone has installed alarms, try to change places as far as possible. If an alarm is triggered, there is no need to worry about it. After the smoke is dispersed, it will automatically stop the alarm.

Third, the power supply is in poor contact and the battery is unloaded and reinstalled.

Fourth, the lack of battery power, replace the new battery as soon as possible, generally DC9V battery can be used for 1 year.

Fifth, the components of the smoke alarms were shaken during the shipping process. Contact the supplier.

When the independent smoke alarm is used for a long time, the following problems may also occur due to the working environment and the alarm working time itself.

If the alarm constantly sounds an alarm, it may be that the alarm has accumulated too much dust or the alarm has been used for too long, or the alarm may be faulty. Sensors in the alarm can become sensitive to smoke if they are used for too long. In the absence of too much smoke, the alarm will also sound an alarm. All home alarms should be replaced after ten years of use. Perhaps the alarm you bought is expensive, but even new alarms may be faulty. If a newly purchased alarm continuously sounds an alarm, it should be replaced with a new alarm.

If there is no fire, how can the alarm be issued intermittently? If this happens, it may also be due to the alarm being used for too long. Or there is too much dust inside, or it may be that the alarm has gone wrong. But sometimes, the battery emits a buzzing sound every about one minute when it runs out. Some people think this is a false alarm.

But this kind of sound is very different, because it sends a single, short sound, and it sounds about once every minute. If your alarm sounds intermittently, you can replace the battery to see if it solves the problem. If not, consider replacing the alarm or cleaning it. When cleaning the alarm, clean all the small ports of the vacuum cleaner close to the alarm. The dust that accumulates on the cover of the alarm can be completely removed. If dust cannot be removed, it will only be replaced.

Steam or moisture will condense on the sensor and the circuit board. If too much water vapor is condensed, an alarm sound will be emitted. The alarm device should be installed in a location far away from the steam and moisture. For example, the alarm should not be installed in the corridor of the bathroom. This can solve the problem. However, if the alarm is supposed to work properly and it now reacts to steam or moisture, the problem may be the cause of the alarm's aging. Older alarms become more sensitive and easier to respond to steam and moisture. Therefore, the occurrence of false alarms may also be due to the fact that the alarm exceeds the service life and needs to be replaced.

Under normal circumstances, the smoke alarm will not respond to cigarette smoke unless the smoke produced is very strong. For example, many smokers who smoke in the same room may cause an alarm if they stand close to the alarm device. The ground blows at it and it responds, but not always. If the alarm is too old, it will respond even if the smoke is low. Therefore, on the contrary, we can also judge whether the alarm has been aging.

Poor contact with the battery is not a practical way to repair, this may be due to the alarm is too old or replace the battery, but it is also a signal to replace the alarm device.
