The Digi-Code CR2154 is a replacement photoelectric safety sensor set engineered for Raynor garage door openers that use the PEC-R3 photo eye system. This sender-and-receiver pair creates an invisible infrared beam across the door opening; if the beam is interrupted by a person, vehicle, or object, the opener stops and reverses to help prevent entrapment. Designed as a direct replacement part for PEC-R3-equipped operators, it restores reliable safety-beam operation on compatible Raynor residential or light commercial installations where the original photo eyes have failed or are missing.
Installation typically involves mounting each sensor on the left and right track near the floor and wiring them to the opener’s dedicated photo eye terminals, then aligning the lenses so the beam remains steady. No wireless pairing is required. Because photo eyes are brand- and system-specific, this CR2154 kit is intended only for Raynor operators that originally used PEC-R3 sensors and is not a universal retrofit for other brands or sensor types. For best results, confirm your opener’s model and the existing sensor designation before ordering, disconnect power during installation, route wiring away from moving hardware, and verify proper door reversal after alignment.
