Camden CM-4000/60N Additional N/O Circuit Module
Overview
The CM-4000/60N is an additional normally-open (N/O) relay output circuit designed to expand the control capacity of Camden's CM-3000 through CM-8000 electronic lock systems. This accessory adds discrete relay channels for controlling supplementary strike mechanisms, access control devices, or door monitoring equipment in networked multi-door installations where the base controller's native output count is insufficient. Install this when your access control topology requires more controlled outputs than the primary control unit provides.
Compatibility
The CM-4000/60N integrates with Camden CM-3000, CM-4000, CM-5000, CM-7000, and CM-8000 series networked door control systems. The module operates at 30VDC and connects into the same access control network that supports DESFire, MIFARE, HID, SEOS, and 125 kHz proximity credentials via smart card readers. Confirm your base controller model and available expansion slots before ordering — this accessory does not function as a standalone device.
Installation Notes
The N/O circuit configuration accommodates standard electromagnetic lock and strike applications at 30VDC. Wire the module into the available expansion port on your primary control unit; exact terminal positions and current ratings depend on your specific base controller revision. Refer to your control unit's installation guide for slot location, terminal identification, and any voltage regulation or current-limiting requirements for the connected strike or solenoid. Verify strike coil impedance and inrush current against the relay rating before final commissioning.
