Alarm Controls Corporation MCK-4-2WP Weatherproof Key Switch

Product Description

The ALARM CONTROLS CORPORATION MCK-4-2WP is a weatherproof key switch designed for access control and exit device applications. Key switches of this type provide a secure, keyed-cylinder actuation point that signals a control panel or releases an electric locking device. The weatherproof construction makes it suitable for outdoor or exposed installations where moisture, dust, and environmental conditions would compromise a standard switch. It is typically installed by licensed electricians or access control technicians as part of a broader entry or egress system.

The MCK-4-2WP is intended for use in access control systems at exterior doors, gates, and secured entry points in both residential and light commercial settings. It serves as a keyed override or activation point for electric strikes, magnetic locks, or door release circuits. Installations commonly involve surface or flush mounting at door frames or adjacent wall surfaces where a tamper-resistant, weather-rated control point is required.

Key Features

• Weatherproof enclosure rated for outdoor and exposed-environment installations
• Keyed-cylinder actuation for secure, authorized access control

Compatibility

Installation Notes

Installation should be performed by a licensed electrician or certified access control technician. Disconnect and de-energize all associated control circuits before wiring or mounting the switch. Follow applicable NEC requirements for low-voltage control wiring and ensure the mounting surface provides adequate weatherproof sealing at all conduit entries. Do not energize the circuit until all wiring connections are confirmed secure and the enclosure is fully closed.
