There has always been a small red light on the smoke.

There is a small red light on the smoke. What happened? Let's watch together.

Can the smoke sensor keep flashing red?

1. If the smoke detector keeps flashing red, it means that it has been working and has detected the existence of dense fog in the room. If you want to turn it off, you can directly press the reset button above, and you can turn off the problem of flashing back all the time by pressing it once. If there is still no response, you can directly cut off the power supply and successfully shut down.

2. Generally speaking, smoke detectors installed indoors can't be turned off at will, otherwise fire hazards can't be detected well. If you don't want it to sound an alarm, you may need to break the alarm so that it can't detect the danger of fire. But this method is not recommended. There are many reasons why smoke alarms keep flashing red.

If the smoke detector keeps ringing, it may be that the power supply is dead. When it's almost used up, the alarm clock will ring every minute. Of course, it will be different from the real alarm, just a warning message of insufficient power. Another is that there is indeed smoke in the room. For example, if someone smokes, when the smoke concentration reaches a certain range, it will cause an alarm.

What is the principle of smoke detector?

There are radioactive substances in the sensor of ion alarm, which will generate current. When the smoke particles in the smoke enter the sensor, it will disturb the current and make the alarm sound. The photoelectric alarm will emit infrared rays. When there are smoke particles in the room, the light beam will scatter to the sensor, and the sensor will give an alarm after sensing a certain beam.

Under what circumstances will the smoke sensor alarm?

1. In the initial stage of light-off, an alarm will be given when combustible gas is released.

2. When smoke is generated, this product will give an alarm sound.

3. When the substance burns, the smoke detector will sound an alarm.

4. With the increase of ambient temperature, the substance releases a lot of heat, which will make the smoke sensor give an alarm.
