MOUNTING YOUR SENSORS
Before you mount, choose a mounting location:
•
The recommended mounting height is 3 feet (0.9 m). This will help avoid false alerts from
small animals crossing under the beam but still detect people and vehicles.
•
The sensors can be mounted up to 300 ft. (91.4 m) apart.
•
Mount the sensors on a stable surface. Do not install where trees or other objects can block
the beam.
Circular post mounting
1. Attach the right-angle bracket to the cross bracket using two M4 nuts and two M4 × 12 mm
bolts. Repeat for all brackets.
2. Attach a right-angle bracket to the top and bottom of each sensor unit using four M5 nuts
and four M5 × 18 mm bolts.
3. Mount sensor unit B fi rst, attaching it to a post with two U-shaped brackets, four M5 nuts,
and four M5 × 27 mm bolts. Tighten securely, making sure that the sensor is level and the IR
windows are facing toward where you will mount sensor unit A.
Note:
If the U-shaped bracket doesn’t fi t your post, use a vise to bend it to the correct shape.
4. Mount sensor unit A to a post with two U-shaped brackets, four M5 nuts, and four
M5 × 27 mm bolts. Tighten securely, making sure that the sensor is level and that the IR
windows are facing toward sensor unit B.
Note:
When the sensor units align, sensor unit A’s indicator light blinks.
