The Camden Door Controls CM-420G/3 is a single gang exit push button station designed for access control and door release applications. It provides both normally open (NO) and normally closed (NC) contact outputs, giving installers the flexibility to interface with a wide range of access control panels, magnetic locks, electric strikes, and door release systems. The CM-420G/3 is a standard single gang form factor, making it straightforward to mount in conventional electrical boxes commonly found in commercial entry and egress points.
This push button is suited for commercial and institutional access control installations where a surface-mounted or flush-mounted egress device is required. It fits naturally into door control systems at lobbies, server rooms, restricted corridors, and other controlled access areas. The dual contact configuration allows integration with both fail-safe and fail-secure locking hardware, reducing the need for additional relay modules in many installations.
Designed as an OEM-style exit push button for commercial access control and door release systems requiring a single gang, dual-contact push button station.
Installation is typically performed by a licensed low-voltage or electrical contractor familiar with access control systems. De-energize all connected locking hardware and access control panels before wiring the device. Mount in a standard single gang electrical box per local electrical codes and the manufacturer wiring diagram. Verify NO and NC contact terminations match the requirements of the connected access control panel before restoring power.
