K1D6761-1CCMC is an AC Logic Control Board Replacement Kit. For use with Commercial Swing and Slide Gate Operators. Manufactured after 2016 only. This AC logic board is backwards compatible for older second-generation units but requires UL 325 Monitored Entrapment Protection System and Monitored Photoelectric Sensors or Edge Sensors on the OPEN entrapment zone that are MANDATORY. Failure to add the Monitored Entrapment Protection Devices will cause the gate operator to not operate or function properly.
