Camden Door Controls CM-4000G/7 Mushroom Push Button

Product Description

The Camden Door Controls CM-4000G/7 is a green mushroom-head push button wired in a normally open (NO), momentary-contact configuration. Momentary NO buttons complete a circuit only while pressed, then return to their open state when released. This type of button is a standard control device used to trigger electric strikes, magnetic locks, automatic door operators, and access control systems. Electricians and low-voltage security technicians install this button as a request-to-exit (REX) or door release control in commercial and institutional entry systems.

The CM-4000G/7 is suited for commercial door control applications where a clearly visible, tactile push button is required at an egress or access point. The green mushroom head provides an immediately recognizable visual cue for users, making it common in healthcare, education, and commercial office environments. It is typically surface-mounted near a door frame or on a wall plate adjacent to a controlled door. The momentary NO wiring configuration integrates directly with access control panels, intercoms, and automatic door operator inputs.

Key Features

• Normally open (NO) momentary-contact switching action
• Green mushroom-head actuator for high visibility at access and egress points
• Designed for REX, door release, and automatic door operator trigger applications
• Single-unit packaging for individual installation or replacement

Compatibility

Designed as an OEM-style control button for use with electric strikes, magnetic locks, and automatic door operator systems requiring a normally open momentary input signal.

Installation Notes

Installation is typically performed by a licensed electrician or low-voltage access control technician. De-energize the access control panel and any connected door hardware before wiring. Follow local electrical codes and the door operator or access control manufacturer wiring diagrams when making connections. Verify the NO momentary configuration is compatible with the panel input before commissioning.
