Alarm Controls MCK-4-5 MKT Series Mortise Cylinder Station, Single Gang

Built for installers and security integrators who need a compact, reliable access control interface, the Alarm Controls by ASSA ABLOY MCK-4-5 keyswitch delivers durable, professional-grade performance for monitoring and entry workflows. The stainless-steel faceplate accepts standard 1-1/8" mortise cylinders, providing a tamper-resistant mounting that blends with commercial hardware. With just 1.25" depth behind the plate, the mortise cylinder station streamlines single-gang installations and reduces labor on retrofit projects. Color-coded switch leads and LED indicators that operate on 12 or 24 V AC/DC simplify wiring, commissioning and status verification, while switch contacts rated 4A at 28VDC reliably control locks, alarm inputs or auxiliary circuits. Designed for access control, surveillance, and security monitoring applications, the MCK-4-5 integrates cleanly with panels and control systems to improve uptime and reduce troubleshooting time. Specify the MCK-4-5 for secure, easy-to-install keyswitch functionality in commercial buildings, data rooms, or perimeter access points—contact sales or add to your next project order.
