Your Residential Garage Door Opener is
furnished with an enhanced 2 Wire Safe

Time-Saving Electrical Connections. No
screw terminals! Just strip the ends of the
wires back 5/16 inch and use the supplied
wire nut connectors for a quick hook-up to
pre-wired garages or to the wires you run on
site. See the figure above applicable to your
installation.
Universal Wiring Capabilities. The Safe
Finish™ Photosystem can be wired in series
or parallel combinations. Virtually any
existing wiring can be used. See the figures above.
Improved Sunlight Immunity. Under certain conditions, direct sunlight can overpower photobeam
systems. We have provided an extra internal circuitry to reduce sunlight problems. When required,
the position of the transmitter and receiver may be interchanged with out rewiring.
