FFA-TF Waterflow Switch

Description

TF Waterflow Switch – Fire Sprinkler Water Flow Monitoring Device

The TF Waterflow Switch is a reliable monitoring device designed to detect water movement in fire sprinkler and fire protection piping systems. When water flows through the pipeline, the mechanical paddle or vane mechanism activates the switch, sending an alarm signal to the fire alarm control system for rapid notification and monitoring.

Engineered for dependable operation, the TF Waterflow Switch features a corrosion-resistant housing and durable internal components designed for use in commercial, industrial, and building fire protection applications. The device provides accurate water flow detection while supporting system supervision and emergency response requirements.

The switch is available with SPDT alarm contacts and is designed for integration with fire alarm panels and monitoring systems. Depending on the model configuration, it can be installed on compatible sprinkler piping using suitable connection arrangements.

Key Features:

  • Waterflow detection switch for fire sprinkler systems
  • Mechanical paddle/vane type flow sensing mechanism
