Magnasphere Corp MSS-54SL-W Surface Mount Contact

Product Description

The MAGNASPHERE CORP MSS-54SL-W is a surface mount magnetic contact designed for security and access control applications. This normally closed contact ships with jacketed leads in white finish, making it suitable for installations where a clean, low-profile appearance is required. Packaged as a single unit, it is intended for professional installation by security technicians and electricians working on door or window sensing circuits. The MSS-54SL-W provides a reliable open-circuit signal when the contact pair is separated, triggering the connected alarm or access control panel.

This surface mount contact is used in residential and light commercial security systems, typically mounted to door or window frames and their corresponding moving panels. The normally closed wiring configuration is the standard for most alarm loops, ensuring that a broken wire or separated contact generates an alarm condition. The jacketed leads allow for neat, protected wire routing through or along the mounting surface.

Installation Notes

Installation should be performed by a licensed security technician or electrician familiar with low-voltage alarm wiring practices. Power down or disarm the alarm control panel before connecting or disconnecting contacts on a live loop. Leads should be routed and secured to prevent mechanical stress at the contact body. Local codes and the control panel manufacturer guidelines should be consulted for loop resistance and wiring specifications.
