Liftmaster CPS-RPEN4 Monitored Retro-Reflective Photo Eye for Commercial Door Applications
LiftMaster’s® CPS-RPEN4 Monitored Retro-Reflective Photo Eye is the versatile, flexible solution for commercial garage doors. The built-in polarized beam offers exceptional reliability by reducing interference from shiny objects. The simple turnkey solution requires power on one side only, and the NEMA 4X enclosure protects electronics from the environment. Our photoelectric eyes and edge sensor models are UL/cUL Listed for use with all LiftMaster Commercial Door Operators. The CPS-RPEN4 can be used as a primary and/or ancillary entrapment device and meets UL 325 2010 safety standards.

• Polarized beam for use in applications with highly–reflective surfaces.
• NEMA 4X enclosure protects against direct water–spray and corrosion.
• Retro-reflective sensor.
• For indoor/outdoor use.
• Maximum range of 50 feet.
• Sensor light off indicates correct sensor alignment.

UL 325 requires all commercial door operators to be either constant pressure to close or be equipped with a primary external monitored entrapment protection device. The Liftmaster CPS-RPEN4 Monitored Retro-Reflective Photo Eye for Commercial Door Applications meets this requirement. Failure to use the appropriate sensor or failure to install the sensor properly, may expose the installer and customer to liability, should an accident occur.
