Page 3: Introduction
Local Control Stations (LCS) LCS should be mounted firmly in an accessible location. The LCS is considered by the Sigma XT FIP to be a STATUS UNIT(S). Status units have monitored inputs to which remote Hold or Mode select switches can be connected. -

2. Mounting Internal Signs Remove Cover Internal circuit board. Mount using suitable fixings. Select cable entry point and prepare. Leave enough tail on cable to ensure the cable will not interfere with operation of sign. Weatherproof - External Signs Mount Sunshade. Remove cover Internal... -
Page 5: Power And Data Connections
3. Power and Data Connections Each status unit requires two cores for power and two cores for data transmission to and from the control panel. A four core cable may be used for these connections. All of these connections are polarity conscious and care should be taken to match the polarity with the corresponding terminals at the control panel. -
Page 6: Connecting More Than 3 Signs
3.1.2. Connecting more than 3 Signs For systems requiring more than 3 signs (or devices), wiring is as follows: Notes: • FIP MUST BE POWERED DOWN BEFORE ANY CHANGES TO SIGNS. • Connections for the first 3 signs or devices remains the same as the previous wiring diagram. •... -

4. Connection of Local Control Station (LCS) Power and Data Connection The LCS can be installed in any order on the STATUS SERIAL (RS485) circuit, depending on its location. The LCS must be installed on the STATUS SERIAL (RS485) circuit. It cannot be used as a mimic device. More information is available on the Local Control Station Manual. -
Page 8: Connection To Hold And Mode Inputs
Connection to Hold and Mode inputs Status units have monitored inputs to which remote Hold or Mode select switches can be connected. These inputs are monitored for open and short circuit faults and therefore need to have a 470R 1W trigger resistor connected in series with the activating, normally open switches and 6K8 0.5W end of line monitoring resistors connected across the end of the cables. -
Page 9: Processor And Watchdog Reset Switches
Processor and Watchdog Reset Switches The status unit is controlled by a microprocessor, which will re-start itself and continue to run if it stops for any reason such as severe electrical interference such as an electrical storm. To ensure that the unit is not being subjected to continual, undue interference which may affect its proper operation, a CPU fault indicator is latched on and a fault condition signalled to the control panel. -
Page 10: Setting Up The Devices
5. Setting up the Devices Sign Circuit Board LCS Circuit Board Addressing Devices Before adding a device to the FIP’s programming, each device connected to the STATUS SERIAL (RS485) circuit must be given an individual address. The FIP MUST BE POWERED DOWN BEFORE ANY CHANGES TO DEVICES. IMPORTANT - Devices with the same address will cause an intermittent fault to be displayed. -
Page 11: Adding Devices To Fip Programming
6. Adding Devices to FIP Programming In order to add or remove devices from the FIP programming, the FIP must be in “ACCESS LEVEL 3”. The steps to enter “ACCESS LEVEL 3” are as follows: 1. Unlock and open the centre display window. This operates a read switch on the door that enables “ACCESS LEVEL 2”. -
Page 12: Alternative Sign Arrangements
7. Alternative Sign Arrangements Mimic Signs / Connecting more than 7 Signs In systems that require more than 7 signs, additional signs may be installed by connecting to the 24VDC TRIGGER terminals located in each sign. This allows connected signs to mimic the operation of a sign that is connected to the STATUS SERIAL (RS485) circuit. -
Page 13: Alternative Arrangement Of Status Serial (Rs485) Circuit
Alternative Arrangement of STATUS SERIAL (RS485) Circuit. The standard arrangement for installing signs is to have a single STATUS SERIAL (RS485) cable connecting the FIP to the signs, as per wiring diagram. However, it can be configured to have 2 separate cables for the RS485 circuit with the FIP effectively in the middle of the circuit rather than at one end. -
