TTK FG-ALS4 Four-Zone Alarm and Location System Unit Installation Guide

TTK FG-ALS4 Four-Zone Alarm and Location System Unit

Panel Mounting

• Fix the panel to the wall using 4 screws (not included).
• Five push-through holes are provided for installing the PG11 glands.

1. Power supply
2. Relays
3. Outputs 1&2
4. Outputs 3&4
5. JBUS/MODBUS

• Knock out the push-through holes from the outside.
• Connect all plug-in terminals (refer to step 2).
• Plug the terminals.
• Close the box, starting by inserting the top side, and then push the bottom down. Lock, using the two available screws.
• Power up from the circuit breaker

Electrical Connections

• Connect the sense cables following this color code:
  A: Green
  B: White
  C: Black
  D: Red
  Terminate unused outputs with two loops between connectors A & B and C & D.
  The wiring diagram is on the back page.

• Connect the relays:
  COM: Common
  NC: Normally Closed
  NO: Normally Open

• Five relays are available on FG-ALS4:
  Relay 1 = leak zone 1
  Relay 2 = leak zone 2
  Relay 3 = leak zone 3
  Relay 4 = leak zone 4
  Relay 5 = cable-break all zones

• Connect the power supply following the signs:
  Ground sign: Ground
  N: Neutral
  L: Live
  Power supply : 100-240 V AC 50/60 Hz 0.25 A

Capacity

The FG-ALS4 panel is designed to receive up to 45m (147 ft) of sense cable (FG-ECS, FG-ACS, FG-ECX, FG-ACX) per zone.

Powering-on the System

Power on from the circuit breaker:
The panel will sound and show ‘‘SYSTEM TEST’’ for 20 seconds on the display, and will then show the ‘‘home’’ screen:

Settings

• Touch the second button (arrows), the touch screen shows the lengths installed on each of the four zones:
  

• Alarm screen:
  If a fault occurs (leak or cable-break), the leak alarms are represented by a drop of liquid;
  Cable-break alarms are represented by scissors and the ‘‘sensor’’ label.
  
  The system will return to the ‘‘home’’ screen after 30 seconds of inactivity.

MODBUS

The MODBUS protocol implemented on FG-ALS4 allows the current status of the system to be supervised. The two types of alarm (leak and cable-break) are coded using different Modbus registers for each individual zone.
The physical support of the MODBUS is two-wire RS485.

Register 2 = leak zone 1
Register 3 = cable-break zone 1 Register 4 = leak location zone 1
Register 5 = length zone 2
Register 6 = leak zone 2
Register 7 = cable-break zone 2 Register 8 = leak location zone 2
Register 9 = length zone 3
Register 10 = leak zone 3
Register 11 = cable-break zone 3 Register 12 = leak location zone 3
Register 13 = length zone 4
Register 14 = leak zone 4
Register 15 = cable-break zone 4 Register 16 = leak location zone 4

Format of the solution:

Slave number

| Function| No. of bytes read| Byte 1| Byte 2| …| Byte N| CRC 16
---|---|---|---|---|---|---|---
1, 2, …, 255| 3 or 4| up to 32| XXh| XXh| …| XXh|

XXXXh

• Remarks:
  – The last panel on the serial link should be terminated with a 120 Ohms / 1W resistor between points RT- and RT+. The shielding of the data transmission cable should be connected to the controller’s earth and to the terminal COM of each FG-ALS panel.
  – Slave number 0 inhibits the MODBUS operation.
  – It is advisable to leave at least 200 ms between the successive requests.
