IMPORTANT INFORMATION ABOUT THE LIFTMASTER
MONITORED ENTRAPMENT PROTECTION DEVICES
A LiftMaster Monitored Entrapment Protection (LMEP) device
is required for most wiring types. If a LiftMaster Monitored
Entrapment Protection device is not installed, constant pressure to
close will be required from the control station.
When properly connected and aligned, the photoelectric sensors
will detect an obstruction in the path of its invisible light beam. If
an obstruction breaks the light beam while the door is closing, the
door will stop and typically reverse to the full open position.
The photoelectric sensors must be installed facing each other
across the door, no more than 6" (15 cm) above the fl oor.
AVERTISSEMENT
Each photoelectric sensor has an LED that will glow steady when
the sensor is properly connected and aligned. The LEDs on both
photoelectric sensors will fl icker rapidly when obstructed or
ATTENTION
misaligned.
