Chamberlain CPS-UN4 Manual

INTRODUCTION
APPLICATION
NOTE: The images throughout this manual are for reference and
your product may look different.
The Commercial Protector System is suitable for use in
applications where the photoelectric sensors will be exposed to
moisture. The CPS-UN4 and CPSUN4G are LiftMaster Monitored
Entrapment Protection (LMEP) devices and are compatible with
the following operators:
LiftMaster Models FDC, FDCL, FDO, and LGE, Medium
Commercial Door Duty Logic, Logic 3, Logic 4, and Logic 5
Operators
LiftMaster Legacy Models CSL24V, CSW24V, RSL12V,

and SL595U family
IMPORTANT INFORMATION ABOUT THE
PHOTOELECTRIC SENSOR
Be sure power to the operator is disconnected.
When properly connected and aligned, the photoelectric sensor
will detect an obstruction in the path of its invisible light beam.
If an obstruction breaks the light beam while the door/gate is
closing, the operator will stop and typically reverse to the full open
position.
The sensors must be installed so that the emitter and receiver
sensors face each other across the entrapment zone and the beam
is no more than 6" (15 cm) above the fl oor for a commercial door
and no more than 27.5" (69.8 cm) above grade for a gate for
entrapment protection. Either can be installed on the left or right of
the entrapment zone as long as the sun never shines directly into
the receiver eye lens.
The brackets must be securely fastened to a solid surface such as
the wall framing. If installing in masonry construction, add a piece
of wood at each location to avoid drilling extra holes in masonry if
repositioning is necessary.
The invisible light beam path must be unobstructed. No part of
the gate or door (or door tracks, springs, hinges, rollers or other
hardware) may interrupt the beam while the door/gate 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.
For commercial doors, additional photoelectric sensors may
be added at heights greater than 6" (15 cm) above the fl oor for
vehicle/property detection.

MODELS CPS-UN4 AND CPSUN4G
To prevent possible SERIOUS INJURY or DEATH from a closing
gate or door:
• Entrapment protection devices MUST be installed per the
operator owner's manual for each entrapment zone.
• Be sure to DISCONNECT POWER to the operator BEFORE
installing the photoelectric sensor.
• The gate or door MUST be in the fully opened or closed
position BEFORE installing the LiftMaster Monitored
Entrapment Protection device.
• Correctly connect and align the photoelectric sensor.
• For entrapment protection, install the photoelectric sensor
BEAM NO HIGHER than 6" (15 cm) above the fl oor for door
and 27.5" (69.8 cm) above grade for gate operators.
