Potter Electric 1010203 Post Indicator Valve Supervisory Switch

Product Description

The Potter Electric Signal Co. US 1010203 is a post indicator valve supervisory switch used in fire suppression systems to monitor the open or closed position of a post indicator valve (PIV). When the valve moves away from its fully open position, the switch generates a supervisory signal at the fire alarm control panel, alerting personnel to a potential impairment. Licensed fire alarm technicians and sprinkler contractors install this switch as part of a wet or dry pipe sprinkler system's monitoring infrastructure. It is a single-unit component sold individually.

This supervisory switch is suited for commercial and industrial fire suppression installations where post indicator valves are installed on underground water supply mains. Mounting directly to the PIV housing, it provides continuous status monitoring required by NFPA 13 and NFPA 72 for supervised valve positions. It is typically installed during new sprinkler system construction or as a replacement on existing PIV assemblies that require code-compliant supervisory monitoring.

Key Features

• Monitors post indicator valve position for open or closed supervisory status
• Generates a supervisory signal upon valve movement from the fully open position
• Supports compliance with NFPA 13 and NFPA 72 supervised valve requirements

Installation Notes

Installation should be performed by a licensed fire alarm or sprinkler system contractor in accordance with NFPA 13 and NFPA 72. Before servicing or replacing the switch, notify the monitoring station and follow the authority having jurisdiction (AHJ) impairment procedures. Shut down power to the fire alarm control panel circuit serving this device before making wiring connections. Do not place the system back in service until the supervisory switch has been tested and verified to signal correctly at the panel.
