The Retrorefl ector Photo Eye transmits an invisible light
beam to the Refl ector and then bounces the beam back to the
Retrorefl ector Photo Eye. The units can be installed on either side
of the garage door as long as the sun never shines directly into the
Retrorefl ector Photo Eye lens.
The brackets must be connected and fastened so that the Refl ector
and Retrorefl ector Photo Eye face each other (Figure 1).
If an obstruction breaks the light beam while the garage door is
closing, the door will stop and reverse to full open position.
The brackets must be securely fastened to a solid surface such
as the studs on either side of the door, or add a piece of wood at
each location if installing in masonry construction.
The invisible light beam path must be unobstructed. No part of
the garage door (or door tracks, springs, hinges, rollers or other
hardware) can interrupt the beam while the door is closing. If
it does, use a piece of wood to build out each sensor mounting
location to the minimum depth required for light beam clearance.
