The Allstar 109775 Safe Finish Photo Eye Kit is an OEM safety sensor set designed to provide the required entrapment protection for compatible Allstar/Allister garage door openers. This photoelectric system sends an invisible infrared beam across the door opening; if the beam is interrupted while the door is closing, the operator stops and reverses to help prevent damage or injury. It’s ideal as a replacement part for worn or damaged sensors or as an upgrade on operators that support Allstar’s Safe Finish interface in residential or light commercial applications.
The kit is intended for indoor use and connects via low-voltage leads to the opener’s safety input terminals. For proper operation, install one unit on each side of the doorway near the floor, ensure clear line-of-sight, and carefully align the sensors per the opener’s manual. After installation, test the safety reversal function and keep the lenses clean and unobstructed for reliable performance. Compatibility is limited to Allstar/Allister operators that specifically call for Safe Finish photo eyes; always confirm requirements in the operator’s documentation before ordering or replacing components.
