Potter Electric Signal Co. Us 1010102 Os-y Supervisory Switch

Product Description

The POTTER ELECTRIC SIGNAL CO. US 1010102 is an OS-Y supervisory switch designed to monitor the open or closed position of outside screw-and-yoke gate valves in fire protection water supply systems. This single-contact switch sends a supervisory signal to a fire alarm control panel whenever the monitored valve is moved from its normal fully open position. It is typically installed by licensed fire protection or sprinkler contractors as part of a code-compliant supervisory signaling arrangement. The 1010102 ships as a single unit and is a standard component in waterflow equipment assemblies.

This switch is suited for use in commercial and industrial fire sprinkler systems where valve supervision is required by NFPA 13 or local authority having jurisdiction. It is commonly installed on OS-Y gate valves located at system risers, zone control valves, and sectional shutoffs. The supervisory function ensures that any unauthorized or accidental partial closure of the valve is detected and reported before it compromises sprinkler system coverage.
