The Potter 1029030 is an OEM retard/switch assembly designed as a replacement component for compatible Potter VSR vane-type waterflow alarm switches. It combines the switching mechanism and retard function used to signal water movement in a fire sprinkler piping system to the connected fire alarm system.

This replacement assembly is intended for maintenance and repair of compatible VSR equipment and is designed to restore the waterflow switch's alarm-signaling operation without replacing the complete switch. Confirm the exact VSR model and installation requirements before ordering; installation should be performed by qualified fire-protection personnel.
