Camden Door Controls CM-4000GE Mushroom Exit Switch

Product Description

The Camden Door Controls CM-4000GE is a mushroom-head exit switch with a spring-return actuator, designed for access control and door release applications in commercial and institutional facilities. The large mushroom-style button provides a highly visible, easy-to-activate surface for emergency egress or controlled exit points. Upon activation, the spring-return mechanism automatically resets the button to its original position, making it suitable for momentary-contact applications. Licensed electricians and access control technicians are the primary installers of this device.

The CM-4000GE is used in commercial buildings, schools, healthcare facilities, and other environments where a clearly identifiable exit activation point is required. It is typically wired into electric door strikes, electromagnetic locks, or access control panels as a request-to-exit (REX) switch. The spring-return design suits installations where a single momentary trigger is needed to release a door latch or mag-lock without latching in the activated state.

Installation Notes

Installation should be performed by a licensed electrician or qualified access control technician. Disconnect and de-energize the door control system and any connected electromagnetic hardware before wiring. Follow applicable NEC guidelines for low-voltage control wiring. Verify the switch contact rating is compatible with the load requirements of the connected door release equipment before commissioning.
