Signal Feedback Device Action Tester
Signal Feedback Device Action Tester — ToronFT™ SFD
ToronFT™ SFD Signal Feedback Device Action Tester is a precision pneumatic testing instrument designed for the action pressure and working reliability evaluation of signal feedback devices used in gas fire extinguishing systems. By applying controlled air pressure to the signal feedback device under test and verifying correct actuation behavior across the full required pressure range, the ToronFT™ SFD enables manufacturers and testing laboratories to qualify signal feedback devices for reliable, standard-compliant performance in gas fire suppression system installations.
The signal feedback device action performance tester consists of two integrated sub-systems — an air source part and a test part — providing a complete, self-contained testing platform with a pressure range of 0–10 MPa and expandable test station capability for high-throughput production and certification testing environments.

Theory and Method
Signal feedback device action performance testing evaluates two key parameters: the action pressure at which the device generates its output signal (indicating system activation), and the working reliability of the device across repeated pressure cycles. The ToronFT™ SFD applies controlled air pressure from the integrated air source sub-system through the test part to the signal feedback device under test, increasing pressure at a controlled rate while monitoring for device actuation.
When the signal feedback device actuates at the specified action pressure, the device generates its output signal. The ToronFT™ SFD records the exact actuation pressure using the precision measurement system (±0.5% F.S. accuracy, expandable to higher accuracy) and compares it against the standard-specified acceptance range. Working reliability testing applies multiple pressure cycles to verify consistent actuation performance across the full test sequence. The ±1% F.S. Pressure control accuracy ensures that the pressure conditions during each cycle are precisely reproduced for accurate, traceable results.
