Infrared Password Alarm Human Body Infrared Sensor Anti-theft Device

Product information:

Main Specifications
Detection range: distance 3-5 meters, angle 105 degrees
Working voltage: DC 4.5
Alarm sound level: 105dB (decibel)
Installation requirements:
◆Because the infrared detector has the highest infrared detection sensitivity when the human body moves laterally relative to the lens, while the longitudinal motion sensitivity is poor, so attention should be paid to the angle and height of the horizontal plane of the detector during installation, which has a great impact on the protection area.
◆When installing, the infrared warning device should be avoided to be close to the cold and heat sources, such as the hot and cold air outlet, the air outlet of the air conditioner, the electric heater, the air cooler, etc., and avoid facing the door directly.
◆The remote control infrared warning device should be able to see directly to the protected range, and there should be no obstacles.
◆The remote control infrared alarm should form an included angle of 10-30 degrees with the wall. At this time, the detection distance is the farthest, and the installation angle should be adjusted according to the actual installation.
Instructions:
1. The infrared alarm will wait for 20 seconds after it is turned on, and it will not detect the alarm signal within 20 seconds. You must leave the detection area of the electronic dog within these 20 seconds.
2. If someone enters the detection area of the infrared alarm after 20 seconds, the infrared alarm will be delayed for 5 seconds, which is convenient for the owner to identify. After 5 seconds, if the correct password input is not received, it will emit a harsh sound for 30 seconds The alarm sounds, and the alarm volume is 105 DB. 5 seconds after the end of the alarm sound, if another person touches the infrared alarm, it will alarm again, and the cycle begins again and again.
3. When the infrared alarm alarms, you can enter the correct password to end the alarm.
Precautions:
1. It is recommended that you regularly check whether the infrared alarm is working properly to avoid missing alarms.
2. When the power-on indicator is dark, the alarm sound becomes smaller and the false alarm rate of the infrared alarm is high, the battery voltage is generally insufficient, and the battery should be replaced in time.
