George Risk Industries 29PA Magnasphere Switch Set

Monitor the open or closed condition of a protected door, cabinet, enclosure, or similar movable barrier by connecting a magnetic switch set to a security alarm input. The 29PA configuration incorporates Magnasphere magnetic sensing, giving installers a specifically identified contact technology rather than an unspecified general-purpose sensor. It serves physical-security applications that need a contact-state indication when the monitored opening changes position. MS29PA-W-IND identifies the ordering configuration for the 29PA Magnasphere switch set. Use the complete ordering code when matching an installed unit or selecting a replacement, particularly where the existing alarm design calls for the 29PA designation and Magnasphere sensing. The product is a switch set for protected-opening monitoring, not a controller, alarm panel, or access-control reader. In a real security installation, the switch set forms the field sensing point between the protected opening and the alarm circuit. Its purpose is to report the position relationship of the monitored opening through magnetic sensing, allowing the connected security system to act on that state. The 29PA designation and Magnasphere capability are the useful identifiers for differentiating this configuration within the George Risk Industries contact-sensing range.
