Potter Electric Signal Co. Us 1010202 Osy Supervisory Switch

Product Description

The POTTER ELECTRIC SIGNAL CO. US 1010202 is an OSY supervisory switch with a 2-contact configuration, designed to monitor the open or closed position of outside screw and yoke (OSY) gate valves in fire suppression and sprinkler systems. This supervisory switch signals the fire alarm control panel when a monitored valve has been moved from its normal fully open position, providing early warning before water supply is compromised. It is typically installed by licensed fire protection contractors or sprinkler system technicians working on wet-pipe or dry-pipe sprinkler systems.

This switch is suited for commercial and industrial fire protection applications where OSY-style gate valves are used to control water supply to sprinkler systems. The 2-contact design allows the switch to interface with fire alarm systems requiring supervisory signal circuits. Typical installations are found in warehouses, office buildings, manufacturing facilities, and other occupancies requiring monitored valve supervision per NFPA standards.
