Installation method :

（1）Position：Install the radar on the barrier gate or a bar with the indicator light face up and outside, the bottom of radar should be about 0.6m-0.7m above ground. 

（2）Fine-tuning：Electrify the radar before making holes, keep it close to the bar and make sure there is no subject right in front of radar. If the green light is blinking or constantly on, then slightly move it until the green light is out (making sure the radar doesn’t raise false alarms). 

（3）Drilling and fastening: Make holes on chosen position with a driller, size of drill bits should beM4.5 & M16. After making holes of 2 sizes, put the radar thread through the center hole, fastening the radar with screw to keep it from shaking, then fixating the radar by applying glass cement around it. 

（ 4 ）Connecting barrier gate: Connect the red line of radar power to the positive pole and black line to the negative pole. If the relay of the barrier gate panel is constantly on, connect blue line and orange line on the radar’s output end to the interface of barrier gate switch control; if the relay is constantly off, connect green line and yellow line on the radar’s output end to the interface of barrier gate switch control.
