C:INSTALLING THE OPERATOR

STEP 10: Mounting the Photosystem Wall Brackets Select a mounting

inside edge of the door as possible to offer maximum entrapment protection. The brackets

may be temporarily mounted to the wall (or jamb) with the 1” flathead nail provided. Leave this nail in place after installation of the lag screw below to prevent accidental rotation of the bracket NOTE:

It is very important that the wall brackets be mounted at exactly the same height so they will be

aligned.

Using the 1/4” x 1-1/2” lag screw provided, attach the wall bracket securely to the wall. In some installations it may be necessary to attach wooden spacers to the wall to achieve the required clearance. Expansion bolts (not supplied) may be required to attach brackets to walls constructed of

materials other than wood or gypsum. Repeat for the wall bracket on the other side of the opening.

STEP 11: Wire Connect the Photosystem

Refer to page 20 for wiring diagrams of the Safe Finish™ Photosystem and garage door opener. The following outlines the “PHOTOCELL SERIES CONNECTION (RECEIVER FIRST)” wiring diagram.

A.Run a wire pair (not supplied) around the garage door jamb between the transmitter and receiver "L" mounting brackets. NOTE: Leave about 12” of extra wire at each end. Use a minimum 22 gauge solid "trace" wire (one wire in set should be marked to identify it at each end) for interconnect.

B.Run a wire pair (20 or 22 gage solid wire) from the receiver position (unit with "LED" light in the front, may be either side of the door) back to the rear bulkhead of the garage door opener. NOTE: Leave about 12” of extra wire at the receiver end and about 24” of extra wire at the opener end. Use a minimum 22 gauge solid "trace" wire (one wire in set should be marked to identify it at each end) for interconnect.

C.Strip approximately 5/16” from each wire end at the photosystem units and at the opener.

D.Using two (2) wire nuts (supplied), connect the wire ends at the Safe Finish™ Photosystem transmitter to the pigtail wire ends coming out of the transmitter unit. Observe polarity, connect the trace wire ends (with black stripe) together and the unmarked wire ends together. See wiring diagrams on page 20 .

Using two (2) wire nuts (supplied), connect the wire ends at the SAFE FINISH™ Photosystem receiver to the pigtail wire ends coming out of the receiver unit. Observe polarity, connect the trace wire ends (with black stripe) together and the unmarked wire

ends together.

A.Attach the"U" brackets to the "L" brackets with a 1/4-20 carriage bolt, washer and hex nut (provided). Insert the bolt from the inside of the "U" bracket and hand tighten only at this time.

B.Place the transmitter and receiver units into their respective "U"

brackets. NOTE: It is easier to slip the photosystem units in from the side of the bracket than forcing them in from the front of the bracket. See Illustration, at right.

C.Connect the interconnect wire pair to the garage door opener terminals.

Connect the trace wire (black stripe) to the operator terminal marked “4” and the solid color wire to the operator terminal marked “5”. See Wiring Diagrams on page 20 .
