Entrapment Protection
Monitored Entrapment
Protection
IMPORTANT INFORMATION ABOUT THE
MONITORED ENTRAPMENT PROTECTION
DEVICES
Eyes/ Edge inputs will not be functional until the
system is commissioned / programmed. LED on
Eyes/ Edge will be off until fully commissioned/
programmed.
A monitored entrapment protection device is
required for most operation modes (see "Monitored
Eyes/Edge Configuration" section). If a monitored
entrapment protection device is not installed,
constant pressure to close will be required from
the wall controller.
See "Accessories" section for a complete list of
monitored entrapment protection devices.
Three EYE/EDGE terminals are provided on the
main board and color-coded in YELLOW for easy
identification. There should be only ONE set of
photo eyes or ONE edge sensor or ONE light
curtain connected per terminal.
When installing a set of photo eyes, twist both
White wires together and insert into a COM
terminal. Twist both White/Black stripe wires
together and insert into the EYE/EDGE terminal of
that same MONITORED SET of terminals.
NOTE: Any supported Entrapment Protection
Device can be wired into any of the three
unoccupied EYE/EDGE terminals. Supported
devices are listed in the Accessories Pages.
Typical Entrapment Protection Device(s) Overview
Monitored Edge Sensor
mounted to the bottom
of door.
Monitored Photoelectric
Sensor 6" (15 cm) max.
above the floor.
WARNING
To prevent possible SERIOUS INJURY or DEATH from a
closing door:
•
Be sure power is NOT connected to the door operator
BEFORE installing the pair of photoelectric sensor(s).
•
The door MUST be in the fully opened or closed
position BEFORE installing the LiftMaster Monitored
Entrapment Protection Device(s).
To prevent SERIOUS INJURY, DEATH, ENTRAPMENT, or
PROPERTY DAMAGE:
•
Correctly connect and align the photoelectric sensor.
•
Install the primary monitored photoelectric sensor
beam NO HIGHER than 6" (15 cm) above the floor.
•
This is a required LMEP Device for B2, TS, T, and FSTS
wiring types and MUST NOT be disabled. For D1,
C2, and E2 wiring the installation of an entrapment
protection device is recommended.
•
LiftMaster Monitored Entrapment Protection Devices
are for use with LiftMaster Commercial Door Operators
ONLY. Use with ANY other product voids the warranty.
•
If an edge sensor is being used on a horizontal slide
door,place one or more edge sensors on both the
leading and trailing edge.
•
If an edge sensor is being used on a vertical moving
door,place edge sensors on the bottom edge of the
door.
•
NEVER try to loosen or remove an obstruction that
has impeded the movement of the door. Both the
obstruction and door are under EXTREME tension
and loosening or removing an obstacle, impeding the
movement of the door, can cause SERIOUS PERSONAL
INJURY.
•
NEVER stand under a door that has been impeded by
an obstruction. KEEP CLEAR. Door could move freely at
any time and can cause SERIOUS PERSONAL INJURY.
•
If the door should be obstructed or impeded in its
movement, ALWAYS call an Authorized Trained Service
Technician to clear that obstruction.
NOTE: A set of photoelectric sensors (photo eyes) are
included and must be installed, except for constant pressure
to close. Depending on your installation and usage needs,
please consult with your installation specialist to see if the
addition of a contact edge sensor on the leading edge of the
door, a cable tension monitor and/or a light curtain is also
required.
