Product introduction:
This remote control infrared alarm is a set of infrared detectors and alarms in one, and constitutes an alarm system with wireless remote control and power supply. Once the infrared detector detects the intrusion of illegal human movement, it will immediately start the high decibel alarm siren to send out a 30 second on-site alarm sound, playing a strong deterrent role. The alarm adopts advanced integrated design technologies such as special infrared sensor processing chip, PIR dual thermal infrared sensor, Fresnel lens and advanced digital remote sensing technology, micro power consumption special integrated circuit and automatic temperature compensation technology, and microprocessor decoding control. By detecting the infrared heat radiated by the human body, the probe can be started to give an audible alarm on the spot to prevent theft in time. It is an ideal anti-theft facility for vehicles, families, shopping malls, offices, courtyards and stores along the street. It is a necessary anti-theft product for modern families, shops, enterprises and institutions, and hotels on business trips.
Product features: 1. Infrared detection 2. Remote multi-channel wireless remote control, originally equipped with two remote controls, is the same principle as the TV remote control.
Technical parameters: Alarm sound level: 105dB Remote control distance: 5-10m or so (open ground) Detection range: about 7m Working voltage: AC 220V (self equipped transformer is required), DC 6V (4 No. 5 batteries can be installed inside, self prepared, and low-cost batteries can be purchased in our store). The use of special modules consumes very little power

matters needing attention:
Replace the battery when the remote control distance is shortened.
When the battery is installed in the detector, regularly check whether the battery leaks.
It is recommended that you regularly check whether the infrared alarm works normally to avoid missing alarms.
The detector shall be rain proof, wind proof and sun proof, and indoor heat sources such as air conditioner and stove shall be avoided to avoid false alarm.
When the power on indicator is dark, the alarm sound is reduced, and the false alarm rate of the infrared alarm is high, the battery voltage is generally insufficient. At this time, the battery should be replaced in a timely manner.
