Description

GRI MS4400-A Industrial Surface Mount Magnetic Contact

Overview

The GRI MS4400-A is an industrial-grade surface mount magnetic contact designed for environments where robust security and tamper resistance are paramount. It features three armored cables and utilizes Magnasphere technology for reliable detection. This contact is specifically engineered to resist tampering and defeat attempts, making it suitable for high-security applications and challenging industrial settings. Its surface mount design simplifies installation on various door and window frames.

Compatibility

This magnetic contact is designed for integration with standard alarm panels and surveillance systems that accept dry contact inputs. The closed-loop configuration ensures that any attempt to tamper with the sensor or its wiring will trigger an alarm. It is compatible with systems requiring a reliable, physically hardened sensor for perimeter security or asset protection.

Installation Notes

The MS4400-A requires a secure surface for mounting. The three armored cables provide enhanced protection against cutting or damage. Ensure proper termination of the closed-loop wiring to your alarm panel or VMS to maintain system integrity and tamper detection capabilities. Magnasphere technology ensures a consistent magnetic field detection range, reducing false alarms from minor vibrations.
