FAQ Multi-beam IR Sensors AID-420

Q: What is Chuango Multi-beam IR Sensors AID-420?

A: Chuango Multi-beam IR Sensors AID-420 is a wireless four-beam infrared sensor, widely used as a perimeter guarding device in gated houses, shops, and indoor garages. There are four active infrared beams between the two sensors.

When an intruder walks past the detection area and two or more light beams have been blocked, a wireless signal will be then transmitted to a Chuango alarm hub, triggering an alarm.

2. Slide open the upper and lower mounting cap cover of the Transmitter, place it on the side of the target position, and adjust the horizontal and vertical direction by watching the leveler in the upper mounting cap.

3. Mark the screw holes of the transmitter, then use the hole punch to punch the screw holes, insert the expansion bolt, fix the transmitter with screws, and cover the upper and lower mounting caps.

4. On the other side of the installation position, adjust the position of the receiver by hearing the buzzer rate to ensure that the signal strength is medium or strong (two or three beeps every second). After determining the location, follow steps 2 and 3 to fix the receiver.
