Product Information
The Supervisory Tamper Switch (TS-OSY) is designed for use in
fire service systems to indicate the open or closed position of the
OS&Y gate valve. It is suitable for indoor or outdoor
applications and should only be used with the OSY-TS model of a
valve assembly.
Features
The tamper switch is designed not to bend, loosen, or deflect
from position.
Method of Operation
Before wiring the supervisory switch in a fire protection
system, refer to the following standards:
- NFPA 13: Standard for the Installation of Sprinkler
Systems - NFPA 25: Inspection, Testing, Maintenance of Water-based Fire
Protection Systems - NFPA 70: National Electrical Code
- NFPA 72: National Fire Alarm Code
- CSA C22.1 NO.1 Canadian Electrical Code, Part 1, Safety
Standard for Electrical Installations Section 32 - CAN/ULC-S524, Standard for Installation of Fire Alarm
Systems

FAQ
Q: Can I use the TS-OSY on any type of valve assembly?
A: No, the TS-OSY is specifically designed for use only on the
OSY-TS model of a valve assembly. Tampering and replacement with
non-factory components may adversely affect the safe use of the
system.
Q: Are precise measurements provided in both U.S. customary
units and metric?
A: Watts product specifications in U.S. customary units and
metric are approximate and are provided for reference only. For
precise measurements, please contact Watts Technical Service.
Q: Can product design or materials be changed without
notice?
A: Watts reserves the right to change or modify product design,
construction, specifications, or materials without prior notice and
without incurring any obligation to make such changes and
modifications on Watts products previously or subsequently
sold.

Supervisory Switch
The supervisory tamper switch is intended for use in fire service systems. The switch indicates the open or closed position of the OS&Y gate valve. Designed for indoor or outdoor application.
Features
· Factory installed and tested to eliminate lengthy field instruction and opportunity for error
· Industry-standard switch to meet all traditional specifications and code requirements
· Operation calibrated at factory to eliminate field calibration · Rigid mounting connection to gate valve without brackets that can
bend, loosen, or deflect from position
Method of Operation
The supervisory tamper switch consists of two SPDT switches. The switch sends an electrical signal to a local fire alarm control panel indicating a tampered condition of the attached OS&Y gate valve wheel when turned 20 percent toward the closed direction, or a maximum of four (4) revolutions. The tamper switch assembly consists of two SPDT switches. The switch assembly is designed to send a signal when the valve is closed or when the cover is removed. When the valve is fully open, the switch is in the neutral position. Closing the valve causes the switch rod to come out of the valve stem groove, activating the signal. Removing the cover causes loss of contact with the switch rod, activating the signal.
