HOW THE SYSTEM WORKS

From Detection to Shutoff in Seconds

The controller is the brain of the system - receiving alarm signals from detectors and triggering shutoff valves automatically.

Step 1
Gas Detected

FB-series detector senses gas above 25% LEL threshold and triggers relay output signal.

Step 2
Controller Receives Alarm

EC/FC controller receives the signal, activates buzzer, and illuminates the zone LED.

Step 3
Valve Closes

Dry-contact relay drives the GD-series shutoff valve closed within 15 seconds.

Step 4
Manual Reset

After ventilation and inspection, press RESET to restore normal operation.
