The NIR-50-325 UL 325 Compliant Retroreflective Photoeye Kit is designed for commercial garage door, gate operator, and access-control safety applications where a reliable monitored photoeye system is required. This kit includes the photoeye sensor and reflector hood, making it a practical replacement or upgrade option for compatible commercial operators that require UL 325 compliant external entrapment protection.

A retroreflective photoeye works by sending an infrared beam from the sensor to a reflector and back to the sensor. If a person, vehicle, equipment, or obstruction breaks the beam while the door or gate is closing, the operator can stop or reverse according to the operator’s safety logic. This makes the NIR-50-325 an important safety component for commercial overhead doors, rolling doors, industrial doors, gated entries, and other automated access systems.

This kit is commonly used by garage door technicians, gate operators, access-control installers, maintenance teams, and commercial service companies replacing failed, damaged, missing, or outdated photoeyes on compatible operator systems.

Compatibility & Fitment

The NIR-50-325 is intended for compatible commercial garage door and gate operator systems that accept a UL 325 compliant monitored retroreflective photoeye. Before ordering, confirm the operator model, required safety-device type, voltage/wiring requirements, monitored safety input compatibility, mounting location, and reflector setup.

This is not a universal residential garage door safety sensor kit. It should be used only with operators and control boards that support the correct monitored photoeye configuration. If your operator requires a specific manufacturer-branded monitored sensor, verify compatibility before installation.

The kit includes the sensor and reflector hood. Additional brackets, wire, mounting hardware, conduit, or operator-specific accessories may be required depending on the installation.

Installation Notes

Install the photoeye sensor and reflector according to the operator manufacturer’s wiring diagram and UL 325 safety-device requirements. The sensor and reflector must be mounted securely, aligned correctly, and positioned so the beam protects the required entrapment zone.

Before completing the job, test the operator through multiple open and close cycles. Confirm that the system recognizes the photoeye, stops or reverses properly when the beam is blocked, and does not allow unsafe operation if the device is misaligned, disconnected, or obstructed.

Safety Notice

Garage door and gate operators can cause serious injury, death, or property damage if safety devices are installed incorrectly or bypassed. This product is for professional installation only and should be installed by a trained garage door, gate, or access-control technician.

Never bypass, remove, or disable monitored safety devices. Always confirm compliance with the operator manufacturer’s instructions, UL 325 requirements, and local code requirements before returning the door or gate to service.
