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. NOTE: LED on Eye / Edge will not illuminate. A monitored entrapment protection device is required for most operation modes (see "Monitored Eyes/Edge Configuration" on page 30). If a monitored entrapment protection device is not installed, constant pressure to close will be required from the wall controller. See "Accessories" on page 63 for a complete list of monitored entrapment protection devices. Three EYE/EDGE terminals are provided. Each terminal can accept ONE device. For easy identification during installation, the correct terminals are yellow. CLASS 2 SUPPLY +24V Accessories may connect to the regular or switched port. Switched is turned off at loss of AC to preserve battery life. ACCESSO RY POWER 24VDC, 1A Brown Blue White/Black To EYE/EDGE White To CMN Photo Eyes CPS-U, CPS-UN4, CPS-OPEN4, OES-RD16 LC36M Brown Blue White/Black White Tx Rx Light Curtain LC36M 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 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 needed.
