TTK FG-ALS Alarm Location System is designed to be used with TTK analog sense cables; FG-ECS, FG-ACS and FG-ECX, FG-ACX to give instant detection of liquid leaks (water, acid or base). A LCD display and three LED’s on the front panel indicate presence of Power Supply (green), Leak Detected (red) or Cable Break (yellow). The FGALS also features an RS485MODBUS/JBUS serial link to integrate to a variety of intelligent monitoring systems. If a leak is detected an audible alarm is triggered. The LCD display on the alarm unit front panel will show the distance in metres to the leak, 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’s and corresponding relays remain activated as long as the fault persists. When the fault is corrected the LEDs and relays return to normal status.
