The Guardian of Hydraulic Pathways: Maximizing Network Reliability with Tamper Switches

In active fire protection design, system readiness hinges entirely on unhindered hydraulic flow. You may install premier fire pumps and calibrated sprinkler arrays, but an accidentally closed main control valve completely disables your emergency infrastructure. Our Premium Supervisory Valve Tamper Switches deliver an unyielding, smart security shield across your utility pipelines, actively alerting building management the moment safety valves are compromised.

Operating as a high-precision electromechanical monitor, the device detects mechanical valve displacement. If a monitored gate or butterfly valve is turned just two full rotations from its fully open position, or if the internal switch housing lid is unauthorizedly removed, the dual internal switches actuate, routing a precise supervisory pinpoint signal to your master fire loop immediately.

Rugged Industrial Forging for Critical Pump Room Supervision

Engineered to operate inside dense mechanical environments, demanding plant sub-floors, and humid fire pump rooms, our tamper switches boast exceptional industrial physical endurance. Housed inside a heavy-duty, powder-coated die-cast aluminum enclosure, the internal electrical mechanisms are fully sealed against ambient moisture, dust storms, and structural vibration, yielding dependable, decade-long life safety monitoring.

Key Performance Features & Specifications:

  • Instant Dynamic Monitoring: Triggers an automated system trouble alarm instantly upon detecting unauthorized mechanical valve rotation.

  • Universal Fitting Accommodation: Equipped with flexible, field-adjustable spring rods and structural brackets to fit standard OS&Y valve frames seamlessly.

  • Dual SPDT Switch Contacts: Contains twin sets of internal electrical contacts, allowing installer layout wiring to route loops to both the master panel and auxiliary on-site sirens simultaneously.

  • NEMA Weatherproof Enclosure Integrity: Fully gasketed, anti-corrosive housing built to secure high-tier protection across weather-exposed commercial operations.

  • Absolute Code Certifications: Precision manufactured to maintain elite global badges, holding official UL Listing and FM Approval marks in absolute compliance with NFPA 13, 24, and 72 protocols.

It detects the movement of water inside the pipes (due to a sprinkler head opening) and triggers the alarm system.

Yes, Universal Tamper Switches are specifically designed for retrofitting. They feature adjustable operating rods and heavy-duty mounting U-bolts, allowing installation teams to securely mount them onto a wide range of OS&Y (Outside Screw and Yoke) gate valve sizes already in the field.

The primary purpose is to electronically supervise the open/closed status of critical fire protection valves (such as OS&Y or butterfly valves). If an unauthorized person attempts to close a valve or tamper with the housing, the switch instantly transmits a trouble/supervisory signal to the fire alarm panel, ensuring water paths remain unobstructed.
