Page 4: Inspection Prior T O Installation
UPERVISORY WITCH ENERAL The SOSY-1 supervisory switch is used to monitor the open position of an OS&Y (outside screw and yoke) type gate valve. SOSY-1 supervisory switch shall be installed on each gate valve as to perform the intended function. - Page 5 If this is the case, the bolts can be positioned on the outside of the yoke. The SOSY-1 supervisory switch mounting bracket fits most of the open yoke valves used in fire protection systems. However, some of these valves, especially those less than 1½” in diameter, have irregularly shaped yokes or such limited clearances that the clamping bar cannot be installed properly and/or it causes the valve to bind.
- Page 6 1. Remove and discard the “C-clips” and “roller” from the actuating lever. 2. Set the valve to its fully open position. Remove the SOSY-1 Supervisory Switch from the carton and adjust the position of the retaining nuts to provide sufficient bolt length for the yoke thickness of the valve.
- Page 7 4. Mark the point on the valve stem where the actuating lever contacts the valve stem. 5. Remove the SOSY-1 by loosening the nuts and sliding the clamping bar, remove the SOSY-1 supervisory switch from the valve and set it aside.

The center position is standard position when the switch is installed on the gate valve, the valve is fully opened and the rod of the supervisory switch hanging at the groove of the valve stem.
