Install the Light Curtain (Not Provided)

The following are general instructions for a typical installation, refer to the
complete instructions included with the Light Curtain.
The plug-in power supply accessory (model 100MAPS) is required to power the
Light Curtain. LiftMaster Light Curtain (Model LC-36A) is an ancillary entrapment
protection device designed with 8 optical sensors that form 22 total invisible light
beams which create a cross-pattern or netting effect for maximum protection against
entrapment. If an obstruction breaks any light beam while the door is closing, the
operator will stop and reverse to the full open position. The Light Curtain Transmitter
must be installed facing the Light Curtain Receiver across the entrapment zone, 12"
(30.5 cm) above the primary monitored entrapment protection device. The minimum
installation width is 3 ft. (.91 m) and the maximum width is 33 ft. (10 m).
NOTE: Ensure that no part of the door, door tracks, springs, hinges, rollers, cords or
other hardware interrupts the light beam while the door is closing.
