INTRODUCTION
To prevent possible SERIOUS INJURY or DEATH from a closing door:
• Be sure to DISCONNECT POWER to the operator BEFORE installing the
Monitored Light Curtain .
• The door MUST be in the fully opened or closed position BEFORE
installing the Monitored Light Curtain .
• Mount bottom optical sensor of Monitored Light Curtain no higher than
3" to 6" above the ground if used as primary entrapment protection.
• Correctly connect and align the Monitored Light Curtain transmitter
and receiver.
IMPORTANT INFORMATION ABOUT THE MONITORED LIGHT CURTAIN
LiftMaster Monitored Light Curtain (Model LC36M, Model LC36M41) is an entrapment protection device used with sectional and rolling doors that
®
is designed with 8 optical sensors that form 22 total invisible light beams. These light beams create a cross-pattern or netting effect for maximum
protection against entrapment. When properly connected and aligned, the Monitored Light Curtain will detect an obstruction in the path of the light
beams. If an obstruction breaks any light beam while the door is closing, the operator will stop and reverse to the full open position. The invisible light
beam must be unobstructed. No part of the door (or door tracks, springs, hinges, rollers or other hardware) may interrupt the light beam while the door
is closing.
When the Monitored Light Curtain is installed as the primary entrapment protection device, the lowest optical sensor will need to be installed 6" (15 cm)
maximum above and a minimum of 3" (7.62 cm) from the floor. If the Monitored Light Curtain is the secondary monitored entrapment protection device
it must be installed 12" (30.5cm) above the primary monitored entrapment protection device. The Monitored Light Curtain Transmitter must be installed
facing the Light Curtain Receiver across the entrapment zone.
NOTE: In this application, in order for the lowest optical sensor to be no higher than 6" above the floor, the wiring of the Monitored Light Curtain must
be facing in the upward direction. If installed with the wires facing down, the lowest optical sensor will be much higher than 6" above the ground; it will
be approx. 9-10" above the ground.
