INSTALL
ASSEMBLE AND MOUNT THE BRACKETS
The following instructions show recommended assembly of the bracket(s) and "C" wrap based on the wall installation of the photoelectric
sensors on each side of the door or on the door tracks themselves. There are also alternate mounting methods which may fi t your installation
requirements better. Make sure the wraps and brackets are aligned so the photoelectric sensors will face each other across the door. Mount
sensors no more than 6" (15 cm) above the fl oor and at a width between 7'-30' (2.1 m - 9.1 m).
Fasten the "C" wraps to the mounting brackets having square holes, using
hardware shown.
WALL INSTALLATION
1. Connect each assembly to a slotted bracket, using the hardware
shown. Note alignment of brackets for left and right sides of the
door.
2. Finger tighten the lock nuts.
3. Use bracket mounting holes as a template to locate and drill (2)
3/16" diameter pilot holes on both sides of the door, 4-6" (10-15
cm) above the fl oor. Do not exceed 6" (15 cm).
4. Attach bracket assemblies with 1/4"x1-1/2" lag screws.
5. 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 nuts securely.
6. Center each sensor in the bracket with the lenses pointing toward
each other across the door.
7. Attach the sensors to the brackets with the provided hardware.
Finger tighten the receiving sensor wing nut. Securely tighten the
sending sensor wing nut.
DOOR TRACK INSTALLATION
Discard slotted bracket. Drill 3/8" holes in each track and fasten
securely with hardware . Do not exceed 6" (15 cm).
NOTE: Ensure the door track does not vibrate when the door is in
motion. Excessive vibration can create nuisance reversals.
