The CAMDEN DOOR CONTROLS INC. CM-400R/8 is a single-gang, red push-button access control device designed for push-to-lock applications in commercial and institutional door control systems. It mounts in a standard single-gang electrical box and provides a clean, visible activation point for locking circuits. The red button color gives a clear visual indication of function, making it easy for staff and occupants to identify lock control points at a glance. This type of device is commonly specified by security integrators, electrical contractors, and access control technicians on new installations and retrofit projects.
The CM-400R/8 is suited for commercial interior door applications where a discrete, wall-mounted lock activation point is required. Typical installations include office suite entries, server rooms, medical facilities, and educational buildings where controlled access is needed without a full card reader or keypad. It integrates into low-voltage access control panels and electric locking hardware circuits as part of a broader door security system.
Designed as an OEM-style replacement or new-installation component for single-gang access control and push-to-lock button applications in commercial door control systems.
Installation is typically performed by a licensed electrician or certified access control technician. De-energize the locking circuit and any connected low-voltage power supply before wiring. Follow all applicable NEC requirements for low-voltage control wiring. Verify compatibility with the connected electric locking hardware and access control panel before completing the circuit.
