George Risk Industries MS4400 Industrial Surface-Mount Magnetic Contact

Monitor a surface-mounted door, gate, cabinet, or other protected opening with a closed-loop magnetic contact built around Magnasphere sensing technology. The MS4400-A uses a 3 ft armored cable for the connection run, placing cable protection at the point where exposed lead wire can be vulnerable to damage or interference. Its industrial surface-mount format suits installations where recessed drilling is not wanted or is impractical. Mount the contact at the protected opening and route the armored lead into the compatible alarm circuit. Closed-loop operation supports normally closed alarm inputs, subject to the wiring and input requirements of the connected panel. The contact is described as tamper- and defeat-resistant, making it suitable for physical-security points where resistance to interference is an important installation consideration. Magnasphere technology is the named sensing method used by this contact. Within the MS4400 contact range, this configuration is distinguished by industrial surface-mount construction and a 3 ft armored cable. Select it when those installation attributes, closed-loop signaling, and Magnasphere sensing are the required combination. Evaluate the mounting position, cable route, panel input requirements, and mechanical fit at the opening before installation. The contact addresses the sensing point; system response depends on the alarm equipment connected to its circuit.
