FG-ALS Alarm Locating Unit
Installation Instructions
The FG-ALS Alarm Location Unit is designed to be used with two kinds of TTK analogue sense cables: random FG-ECS, FG-ACS
and pre-connected sense cables FG-ECX, FG-ACX. It allows the leak detection and location of liquids.
The appearance of a fault (leak, cable break) is detected in the following way:
 An audible alarm is triggered;
 A luminous diode turns on;
 A dry contact is activated to transfer the alarm information to remote monitoring equipments.
 JBUS/MODBUS protocol is communicated to BMS.
 The display on the front face shows the leak location (in metre).
To stop the audible alarm, press the “reset” button. The diode and the dry contact remain activated as long as the fault is pre-
sent. When the fault disappears, the diode switched off, the relay returns to its original normal status and the content of the
display disappears.
The maintenance of the system is recommended for every six months minimum.
1. Fixing the FG-ALS Alarm Location Unit
The FG-ALS Alarm Location Unit is available in wall mounted version (165 x 85
x 55 mm).
Two of the three cable glands are placed on the FG-ALS Alarm Unit, the last
one can be screwed in the place of plug PG7.
Use the two fixing holes in the lower part of the unit box. Release the higher
part of the box of the lower part which is maintained by two screws. These two
parts could be easily dismounted after mural fixing. Withdraw carefully the
higher part with the PCB (printed circuit board).

2. Connection and Adjustment
2.1 Power Connection FG-ALS Alarm Unit is powered into 230-240 VAC only.
The maximum section of the cable is of 14 AWG for 230-240 VAC. Use PG9 cable gland for the
cable 230 V.
2.2 Connection of the
Dry Relays
The dry relays are free of potential. The maximum section of the cables is of 18 AWG.
Dry Contact for Leak:
The leak contact transfers the information of leak to a PC (or supervisor), allowing automated
equipment control.
Dry Contact for Cable Break:
A specific contact is activated in case of cable break. A power supply failure also activates this
contact.
Relay of Leak and Relay of Cable Break:
Simple relay: COM-NO-NC
Max. commutated Voltage: 125 VAC / 60 VDC
2.3.Serial Interface
Physical Support Opto-isolated, Two-Wire RS485
2.4. Serial Link Parameters 9500 Baud, 8 Data Bits, 1 bit Stop, no Parity
2.5. Supported Protocol Modbus, Functions 3 and 4
2.3. Adjustment of the
Detection Sensitivity
You can adjust the detection sensitivity, using the potentiometer (P1). The adjustment factory
corresponds to the maximum sensitivity (1 turn).

The FG-CLC leader cable, connected to the FG-ALS alarm unit with a female connector, at its extremity. The beginning of the
sense cable thus corresponds at its extremity with a male connector.
Connect the first sense cable to the leader cable, coming from the FG-ALS alarm unit.
