LiftMaster CPS3 / CPSIII Option Card with CPS-U Photo Eyes – 30' Monitored Commercial Safety Kit

The LiftMaster CPS3 / CPSIII Option Card with CPS-U Photo Eyes is a monitored commercial safety kit designed for compatible LiftMaster commercial door operators requiring an additional set of photoelectric safety sensors.

The kit combines a CPS3 interface card with LiftMaster CPS-U through-beam commercial photo eyes, allowing compatible operator systems to support a second monitored entrapment-protection device.

Designed for a Second Set of Monitored Photo Eyes

The CPS3 card allows compatible LiftMaster commercial operators to accept an additional monitored entrapment-protection device.

This is particularly useful on installations where two separate monitored safety zones are required.

Depending on the operator and control-board generation, the CPS3 interface may support compatible LiftMaster monitored devices including:

• CPS-U photo eyes

• CPS-UN4 photo eyes

• CPS-OPEN4 photo eyes

• CPS-RPEN4 photo eyes

• Compatible monitored sensing edges

This listing includes the CPS-U photo eye set.

CPS-U Commercial Photo Eyes

The included CPS-U sensors create an infrared beam between a sending eye and receiving eye across the door opening.

Key CPS-U features include:

• Up to 30 ft sensing range

• Dual-sided infrared sensing system

• Monitored entrapment protection

• Alignment indicator lights

• High-visibility yellow housings

• NEMA 1 enclosure

• Indoor commercial applications

• UL 325 compliant design

If the beam is interrupted while the door is closing, the compatible operator responds according to its programmed safety logic.

Compatible Operator Systems

The CPS3 interface card is used with select LiftMaster commercial operator control systems, including compatible:

• Logic 3.0 operators

• Logic 4.0 operators

• Logic 5.0 operators

• Select Medium-Duty Logic operators

Compatibility depends on the exact operator model, logic-board generation, and existing safety-device configuration.

Always verify the operator manual or replacement-parts diagram before ordering.

Timer-to-Close Support

When installed on a compatible LiftMaster commercial operator, the CPS3 system can support monitored safety requirements associated with Timer-to-Close operation.

Timer-to-Close automatically commands the door to close after a programmed period, making proper monitored entrapment protection especially important.

Availability and programming of this feature depend on the operator and logic-board configuration.

Important Compatibility Information

This kit should not be confused with:

• CPS-U photo eyes sold without the CPS3 card

• CPS-UN4 NEMA 4 photo eyes

• CPS-OPEN4 monitored dual-sided photo eyes

• CPS-RPEN4 retro-reflective photo eyes

• CPSN4 systems for mechanical operators

Before ordering, confirm:

• LiftMaster operator model

• Logic-board generation

• Existing monitored safety devices

• Whether a second set of photo eyes is required

• Indoor or outdoor installation environment

• Required sensing range

Indoor Use

The included CPS-U photo eyes are rated NEMA 1 and are intended primarily for indoor installations.

For damp, wash-down, dusty, or outdoor environments, a NEMA 4-rated LiftMaster photoeye system may be more appropriate.

Installation & Safety

Commercial photoelectric sensors form part of the operator's entrapment-protection system.

Installation, wiring, positioning, programming, and testing must follow LiftMaster instructions and applicable safety requirements.

After installation, test all photo eyes, monitored edges, door controls, travel limits, and other safety devices before returning the commercial door to service.

Professional installation by a qualified commercial door technician is recommended.
