The SK-KPM and SK-KPS are a digital keypads with a Wiegand output for use with the SecuraKey SKACP, as well as with many other access control systems. Personal Identification Numbers (PINs)are sent to a controller via industry-standard 26bit Wiegand communications. SecuraKey keypads are virtually indestructible. Solid-State piezo technology means no moving parts and no buttons to damage or wear out. The one piece metal housings are fully potted for IP68-rated water-resistance and the anodized graphics never wear off. The SK-KPM is narrow enough to mount to most mullions and door frames, whileSK-KPS covers standard electrical boxes.
