Figures 1, 2 and 3 show recommended assembly of bracket(s) and "C" wrap based on the wall installation of the sensors on each side of the door shown above, or on the door tracks themselves. Figure 4 shows variations which may fit your installation requirements better. Make

sure the wraps and brackets are aligned so the sensors will face each other across the door.

• Connect each assembly to a slotted bracket, using the

hardware shown. Note alignment of brackets for left and right sides of the door. Finger tighten the lock nuts.

• Use bracket mounting holes as a template to locate and drill two (4.8 mm) diameter pilot holes on both sides of the door so that the beam mounting height is no greater than 100 mm above the floor.

• Attach bracket assemblies with carriage bolts as shown.

• Adjust right and left side bracket assemblies to the same distance out from mounting surface. Make sure all door hardware obstructions are cleared. Tighten the lock nuts.

• Centre each sensor unit in a "C" wrap with lenses pointing toward each other across the door.

• Secure sensors with the hardware provided. Finger tighten the wing nut on the receiving eye to allow for final adjustment. Securely tighten the sending eye wing nut.

• Run wires from both sensors to the opener and connect the two white only wires to the white terminal and the black/white wires to the grey terminal on your opener (refer figure 5).
