The ALARM CONTROLS CORPORATION MCK-2-2 is a stainless steel wall plate assembly featuring an integrated SPDT (single-pole, double-throw) switch and a green LED indicator. Designed for access control and exit device applications, this unit provides a durable, corrosion-resistant mounting surface combined with reliable switching action and a visible status light. It is installed by licensed electricians and access control technicians in commercial and light-industrial door control systems where a surface-mounted switch plate with indicator feedback is required.
The MCK-2-2 is suited for exit device and push button applications in commercial buildings, office environments, and controlled-access facilities. The SPDT configuration allows it to interface with a range of access control panels, door release circuits, and alarm systems. The green LED provides a clear visual indication of circuit status, aiding both end users and service technicians during operation and troubleshooting.
Designed as an OEM-style replacement or new-installation component for commercial exit device and push button control systems requiring an SPDT switch plate with LED indication.
Installation should be performed by a licensed electrician or qualified access control technician in accordance with applicable NEC requirements. De-energize all associated circuits and verify lockout before beginning wiring. Confirm that the SPDT switch wiring matches the intended normally-open or normally-closed circuit configuration required by the connected access control panel or door release system. Do not exceed the switch rated electrical load as specified by the manufacturer.
