Alarm Controls MCK-4WP Mortise Cylinder Keystation Spdt

Product Description

The Alarm Controls Corporation MCK-4WP is a mortise cylinder keystation with a single-pole double-throw (SPDT) switch and an integrated weatherproof cover assembly. Designed for access control and exit device applications, this keystation accepts a standard mortise cylinder and uses a keyed input to actuate the SPDT switching mechanism. It is typically installed by electricians or low-voltage security technicians in commercial or industrial environments where exterior or moisture-exposed mounting is required.

This keystation is suited for exterior door access control points, gate operators, and entry management systems where reliable key-operated switching is needed in environments exposed to weather. The weatherproof cover assembly protects internal components from moisture and debris, making it appropriate for outdoor mounting or unconditioned spaces. It falls within the exit devices and push button category, serving as a key-controlled trigger for electric strikes, mag locks, or access control panels.

Key Features

• Mortise cylinder format accepts standard interchangeable mortise cores for keying flexibility
• SPDT switching provides both normally open and normally closed circuit outputs
• Weatherproof cover assembly protects against moisture and environmental exposure
• Compact keystation form factor suited for surface or flush mounting at door frames or posts
• Sold as an individual unit for single-point installation

Compatibility

Designed as an OEM-style replacement or new-installation keystation for commercial access control and exit device systems requiring a key-operated SPDT switch with weatherproof protection.

Installation Notes

Installation is typically performed by a licensed electrician or certified low-voltage access control technician. De-energize all connected access control circuits and confirm the door or gate operator is in a safe state before wiring the SPDT outputs. Follow NEC guidelines for low-voltage wiring methods and enclosure requirements. Verify that the mortise cylinder is properly seated and the cover gasket is fully engaged before returning the assembly to service.
