Chamberlain 771ANZ User Manual

The 771ANZ Photoelectric Beam System is designed to
increase the safety and functionality of your garage door
or gate motor.
The system uses an invisible beam across the garage
door or gate opening. If an obstruction breaks the light
beam while the door/gate is closing, the door/gate will stop
and reverse to full open position.
The units may be installed on either side of the door so
long as the sun never shines directly into the receiving eye
lens. NOTE: The brackets must be connected and fas-
tened so that the sending and receiving eyes face each
other.
The Beams must be securely fastened to a solid surface
such as a stud wall for garage doors or bollard or wall for
gates.
The invisible light beam path must be unobstructed.
Ensure no part of the door (or door tracks, springs, hinges,
rollers or other hardware) interrupts the beam while the
door or gate is closing.
