Below are the two most common mounting options.

Circular Post Mounting

1). Take the right angle bracket (Figure 3-1) and attach the cross bracket using (2) M4 nuts and (2) M4x12mm screws. Repeat for all brackets.

2). Using (2) M5 nuts and (2) M5x18mm screws

attach right angle bracket (Figure 3-2) to units ‘A’ and ‘B’.

3). Attach to post with ‘U’ shaped bracket (Figure 3-3) . Using (2)

2). Use screws that are appropriate for your material and surface (not included) and mount right angle bracket taking care to keep units ‘A’ and ‘B’ level.

Mounting Outside

Figure 4

Units ‘A’ and ‘B’ can be mounted up to 300’ apart. Determine height and location you would like to mount the unit. Recommended height is 3-4’. There must be line of sight between ‘A’ and ‘B’. Units must be mounted level. Install the unit on a stable surface. Do not install where trees or other objects can block the beam. Mounting 3-4’ will avoid false alerts by small animals crossing under the beam, but still detect people and vehicles.

Mount unit ‘B’ first and face the infrared holes toward where unit ‘A’ will be mounted.

When mounting unit ‘A’, face the infrared holes towards unit ‘B’. When the units align there is an audible click in unit ‘A’.

To make sure of proper alignment cover only the top two infrared holes. Unit should not alert. Then cover only the bottom two holes, again unit should not alert. Cover all three holes and the unit should alert. If the unit alerts with only the top two infrared holes covered, raise the unit about an inch to correct misalignment. If the unit alerts with only the bottom two infrared holes covered, lower the unit about an inch. When properly aligned, the unit will only alert when all three infrared holes are covered.
