TTK FG-A-OD, Alarm Unit for Hydrocarbon Leak Detection, is designed to be used with FG-OD hydrocarbon range of products, to provide quick detection of liquid (non-conductive hydrocarbon liquids and solvent). LEDs on the front panel indicate presence of Power Supply (green), Leak Detected (red) or Cable Break (yellow). Responses on the FG-A-OD alarm unit:

  • In the case of leak, an audible alarm is triggered. The red LED is switched on and the leak relay is activated.
  • In the case of cable break, an audible alarm is triggered, the yellow LED is switched on and the cable break relay is activated.

The “SOUND OFF” button on the front panel allows manual silencing of the audible alarm. The LED and corresponding relay remain activated as long as the fault persists. When the fault is corrected the LED and the relay return to normal status.
