Magnasphere Corp MSS-K24S-B Surface Mount Contact

Product Description

The MAGNASPHERE CORP MSS-K24S-B is a surface mount contact designed for use in security, access control, and alarm systems. This type of contact senses the position of a door, window, or panel and signals the control system when an opening occurs. Measuring 2.5 inches in length and 0.5 inches in both width and height, the MSS-K24S-B has a compact form factor suited for installations where space or aesthetics require a low-profile, surface-mounted solution. It is typically installed by security system technicians and licensed electricians working on commercial or residential detection circuits.

Surface mount contacts of this type are commonly used on doors, windows, access hatches, and equipment enclosures in both residential and light commercial applications. The compact dimensions allow mounting in tight spaces where recessed contacts are not practical. This contact is sold as a single unit and is appropriate for new installations or direct replacement of a failed or damaged contact in an existing detection loop.

Installation Notes

Installation is typically performed by a licensed security technician or electrician. Power down or disarm the control panel before connecting or disconnecting contacts to avoid false alarms or system faults. Follow local electrical codes and the control panel manufacturer's wiring guidelines when integrating into a detection loop. Do not overtighten mounting fasteners, as this can crack the housing or shift contact alignment.
