The ALARM CONTROLS CORPORATION MCK-5-4 is a stainless steel momentary push button plate featuring a double-pole double-throw (DPDT) alternate action switch mechanism with a green LED indicator. Designed for access control and exit device applications, this unit provides a clean, durable switching interface suitable for door release, egress, and entry control systems. The alternate action configuration means each press toggles the output state, making it well suited for latching control circuits. The green LED gives a clear visual status indication at the point of actuation. Electricians and low-voltage access control technicians are the primary installers.
This push button plate is used in commercial and institutional access control installations where a surface-mounted or gang-box-mounted actuator is needed at entry and exit points. Typical applications include electric strike control, magnetic lock release, and door access panels in office buildings, schools, and healthcare facilities. The stainless steel construction suits high-traffic environments where durability and appearance are both required. It ships as a single unit and falls within the exit devices and push buttons product category.
Designed as an OEM-style replacement or new-installation push button plate for commercial access control and exit device systems requiring a DPDT alternate action switch with LED indication.
Installation is typically performed by a licensed electrician or certified low-voltage access control technician. Power down the access control panel and de-energize all associated circuits before wiring or replacing this device. Wiring must comply with applicable NEC requirements for low-voltage control circuits. Consult the manufacturer product manual for terminal assignments and wiring diagrams before completing the installation.
