Camden Door Controls CX-MDA Surface Mount Magnetic Contact

Product Description

The Camden Door Controls CX-MDA is a surface-mount magnetic contact designed for use in access control and door monitoring applications. The unit detects door open and closed states by sensing the magnetic field between the contact body and its paired magnet. When the door opens and the magnet separates from the contact, the circuit state changes and signals the access control panel or alarm system. It is installed by low-voltage electricians and access control technicians on doors where concealed mounting is not practical or required.

The CX-MDA is suited for interior doors in light commercial, institutional, and residential access control systems. Typical installations include entry doors, stairwell doors, and server room or utility room doors where door position monitoring is part of an access control or intrusion detection loop. The surface-mount design allows installation without routing hardware through the door frame, making it a practical choice for retrofit projects and installations on hollow metal or wood doors.

Key Features

• Surface-mount design for straightforward retrofit and new-construction installation
• Magnetic reed switch operation for reliable, contact-free door position sensing
• Compact form factor suitable for doors with limited frame space
• Compatible with standard access control and alarm panel input circuits
• Sold as a single unit for flexible deployment across multiple door points

Compatibility

Designed as an OEM-style surface-mount magnetic contact for use with standard low-voltage access control panels and intrusion detection systems that accept door position monitor inputs.

Installation Notes

Installation should be performed by a licensed low-voltage or access control technician in accordance with applicable local codes and NEC guidelines for low-voltage wiring. Disconnect or disable power to the access control panel input circuit before wiring the contact leads. Mount the contact body to the fixed door frame and the magnet to the door leaf, aligning both components within the manufacturer-specified gap tolerance for reliable operation. Avoid mounting on surfaces subject to heavy vibration or impact that could cause nuisance trips.
