Up to 45-Foot Opening
The emitter and receiver create a photoelectric beam across the door opening.
The CPSN4 is intended for openings up to approximately 45 feet wide, making it suitable for many:
-
Commercial sectional doors
-
Rolling steel doors
-
Warehouse doors
-
Loading-area doors
-
Industrial overhead door systems
Mechanical Dual-Relay Operator Compatibility
The CPSN4 was designed specifically for compatible LiftMaster commercial operators using mechanical dual-relay controls.
Because LiftMaster has produced several generations of commercial photoelectric safety systems, the CPSN4 should not automatically be substituted with CPS-U, CPS-UN4, CPS-OPEN4, CPS-RPEN4, or other similarly named photoeye systems.
Always verify the exact operator control system before ordering.
Important Compatibility Information
Before purchasing, confirm:
-
LiftMaster commercial operator model
-
Operator control-board / relay type
-
Required 24VAC power
-
Existing photoeye model or part number
-
Required sensing distance
-
Indoor or outdoor installation requirements
Do not select a commercial safety device based only on physical appearance.
Safety & Installation
Commercial photoelectric sensors can form part of an automated door's entrapment-protection system.
Installation, positioning, wiring, testing, and operation must comply with the operator manufacturer's instructions and applicable safety requirements. After installation, the complete safety system should be tested before the door is returned to service.
Commercial overhead doors and operators contain heavy moving components and electrical equipment. Professional installation by a qualified commercial door technician is recommended.
If you are unsure whether the LiftMaster CPSN4 is correct for your operator, contact Garage-DoorParts.com with the operator model number, control-system information, and photos of the existing safety equipment before ordering.
