How far is the infrared alarm range? How to disarm the infrared alarm when it keeps ringing?

The detection distance of infrared detector is related to the sensing angle and distance. In the past, the sensing angle of infrared detector was 120 degrees, which was enough to meet its functional requirements. Now there is an infrared detector, the sensing angle is 150 degrees, and the performance is stronger. Next, let's find out how far the infrared alarm is, how to remove it when it keeps ringing, and whether it is harmful to human body. I hope I can help you.

1. How far is the infrared alarm range?

1. If someone stands still in the infrared warhead area, the sensor can also sense that the infrared induction is related to temperature, regardless of whether the object is moving. As for the effective distance, different products have different ranges, most of which are 10-20 meters.

2. The detection distance of infrared detector is related to the sensing angle and distance. Early infrared detectors generally set the sensing angle to 120 degrees, which can meet their functional requirements. Now there is an infrared detector with an induction angle of 150 degrees, which has stronger performance but similar functions.

3. The semiconductor components that induce infrared rays generate drift charges, which will form a weak current. After the amplifier circuit is linked with the relay switch, as long as there is an object with temperature, it will radiate infrared rays around itself. The infrared sensor receives the infrared emitted by the object through the sensor, and then amplifies it through the circuit.

Second, how to remove the infrared alarm when it keeps ringing?

1. There are two kinds of infrared alarms: active and passive. Wherein the active infrared alarm actively emits infrared rays. The infrared ray will bounce back when it hits an obstacle, and the probe of the alarm will receive it. If an object comes into contact with infrared rays, the alarm will sound an alarm.

2. If the host of the infrared alarm controller keeps ringing, it depends on what the prompt message is, whether it is a fault or a fire alarm. If it is a fault, it needs to be solved. If there is something wrong with the line, the field equipment is damaged and there is a false alarm, just reset the alarm signal. If there is a fire, it should be handled according to the procedure.

3. Is the infrared alarm harmful to human body?

1, infrared alarm is a kind of electronic appliance, it has a certain degree of electromagnetic radiation, but it is generally controlled within a safe range. The flashing red light or yellow green light on the infrared alarm is a light-emitting diode, which is harmless to human body.

2. The infrared alarm senses moving objects by emitting infrared beams, so it is harmless and will be controlled within a safe range.

3. Some wireless intelligent alarms adopt human pyroelectric infrared or microwave sensors, which can set dozens of defense zones and dozens of alarms *, and can be networked with the community for system management.

The above is about how far the infrared alarm is, how to remove it when it keeps ringing, and whether it is harmful to human body. Thank you for reading. Want to know more about how far the infrared alarm is, please continue to pay attention.
