About Tyco Water Flow Switch Vane Type
The TYCO Model TF Vane Type Waterflow Switch detects a
waterflow condition in a wet sprinkler system.
The switch assembly contains single-pole, double-throw
(SPDT) contacts, and an adjustable pneumatic vane. The
switch activates when a flow rate that exceeds the flow
sensitivity of the switch occurs. The flow condition must
exist for a longer period than the retard delay setting of
the vane for the switch to operate. For information about
the retard delay time ranges, see Retard delay times
Versatile Fire Protection MonitoringThis water flow switch is designed for integration into a wide range of automatic fire sprinkler and fire protection systems. With a stainless-steel vane and corrosion-resistant body, it ensures reliable water flow detection and fire alarm signaling, suitable for both new installations and retrofits in DN50-DN200 piping.
Simple and Secure InstallationThe Tyco Water Flow Switch offers flexible mounting options, including threaded or flanged pipe connections. Pre-wired with a typical 1-meter cable and featuring a 22 mm standard knockout for conduit entry, installation is straightforward. The tamper-resistant cover and easy-access terminal strip streamline connection and maintenance tasks.
Reliable Performance in Demanding ConditionsEngineered for resilience, the die-cast aluminum enclosure offers IP56 ingress protection and a red powder-coated finish for environmental durability. The switch maintains consistent operation at temperatures from 0C to 60C and pressures up to 17.2 bar, meeting the stringent requirements of international safety standards.
FAQ's of Tyco Water Flow Switch Vane Type:
Q: How does the Tyco Water Flow Switch vane type operate within fire protection systems?
A: The switch uses a mechanical vane that is inserted into the pipe. When water flow reaches the minimum activation rate, the vane moves, triggering the integrated SPDT microswitch. This initiates a relay signal for fire alarms or monitoring systems, then resets automatically when flow ceases.
Q: What are the benefits of choosing a stainless-steel vane and die-cast aluminum body for this flow switch?
A: The stainless-steel vane and brass body offer superior corrosion resistance and mechanical strength. Combined with a die-cast aluminum enclosure and red powder coating, these materials ensure the switch maintains accuracy and longevity, even in challenging environments.
Q: Where can the Tyco Water Flow Switch be installed, and which pipe sizes does it support?
A: This switch is designed for inline installation on pipes ranging from DN50 to DN200 (2 to 8 inches). It accommodates both threaded and flanged mounting, making it suitable for commercial or industrial fire sprinkler and fire protection systems.
Q: What process ensures the switch accurately detects water flow?
A: Each unit is factory calibrated for high sensitivity, with an adjustable stainless-steel vane for variable flow rates. It provides a clear on/off operation by activating at a minimum flow of 15 L/min (varies by pipe size), ensuring precise and timely water flow detection.
Q: Which certifications and approvals does the Tyco Water Flow Switch hold?
A: The switch is UL Listed and FM Approved, confirming that it meets strict safety and performance standards required for reliable use in critical fire protection applications.
Q: What are the power and electrical characteristics of the microswitch?
A: The integrated SPDT microswitch is rated for 10A at 250V AC maximum, offering a dry contact relay output. The switch operates on either 24V AC/DC or 230V AC, depending on the selected model, making it compatible with various alarm and monitoring systems.
Q: How does the tamper-resistant cover enhance the usage of the Tyco Water Flow Switch?
A: The tamper-resistant cover, combined with a secure, powder-coated aluminum enclosure, helps prevent unauthorized access or interference, thus maintaining system integrity and ensuring reliable signaling in all operational scenarios.
