Magnasphere Corp MSS-311S Surface Mount Security Contact

Product Description

The MAGNASPHERE CORP MSS-311S is a surface mount security contact designed for use with armored cable. This type of device serves as a tamper-resistant magnetic contact switch, typically installed on doors, windows, or access panels to detect unauthorized opening or movement. The armored cable construction provides added mechanical protection to the wiring, making it well-suited for environments where the cable may be exposed to physical stress or tampering attempts. Licensed security installers and low-voltage technicians are the primary trades that install this component as part of a broader intrusion detection or access control system.

The MSS-311S is intended for surface mounting applications where flush or recessed installation is not possible or practical. It is commonly deployed in commercial, institutional, and light industrial settings where durable, tamper-evident perimeter protection is required. The armored cable version is preferred in applications where standard wiring would be vulnerable to physical damage or where code or site requirements call for additional cable protection.

Key Features

• Surface mount design accommodates installations where recessed mounting is not feasible
• Armored cable construction provides mechanical protection against physical tampering and damage
• Sold as individual unit (each), allowing single-point replacement or expansion
• Suitable for use in commercial and industrial perimeter security applications

Compatibility

Designed as an OEM-style replacement or new-installation component for surface mount magnetic contact security systems requiring armored cable wiring.

Installation Notes

Installation of the MSS-311S should be performed by a licensed low-voltage or alarm systems technician in accordance with applicable local codes and NFPA 731 guidelines. De-energize the security panel or zone circuit before making any wiring connections. Ensure the armored cable is properly supported and terminated according to the panel manufacturer's requirements. Verify correct gap and alignment between the contact and magnet after mounting to confirm proper switch operation.
