Allstar 108994 All Clear Photo Eye Kit

The Allstar 108994 All Clear Photo Eye Kit is a replacement safety sensor set designed for Allstar gate operators and related access control systems. Using an invisible infrared beam between an emitter and receiver, the photo eyes detect an obstruction in the gate or door pathway and signal the operator to stop or reverse movement to help prevent entrapment. This kit is commonly used on residential and commercial slide and swing gate openers and can also apply to select overhead door operators that accept compatible photoelectric safety inputs. It is intended as a direct replacement or upgrade for systems originally equipped with Allstar All Clear photo eyes, helping maintain reliable, code-conscious operation.

Installation typically involves mounting the sensors facing each other across the opening, aligning the beam, and connecting low-voltage leads to the operator’s safety input per the control board wiring diagram. Proper alignment and stable mounting are essential for consistent performance, and the sensors should be positioned at the correct height to meet site safety needs and applicable standards. For best results and UL 325 compliance, verify compatibility with your specific Allstar or Linear/Nortek operator model and follow the manufacturer’s instructions; professional installation is recommended. This photo eye kit supports common use cases such as replacing failed safety sensors, restoring functionality to an older Allstar system, or maintaining a monitored safety zone on automatic gate openers in residential or light commercial applications.
