Control Unit Options
4.1
I/O Matrix 4582
The I/O matrix board is an interface between the FDCIE (COM loop) and various types of
application boards e.g. AS1668 fan control board, Zone Disable and indication board, LED
mimic board, etc.
Up to eight I/O matrix boards 4582 can be used in FT128 if no expansion boards type
4580, 4581 or 4583 are used. The limitation of the I/O matrix configuration as follow:
•
Up to two I/O matrix boards can be programmed in FT128 as type "Zone control"
and / or "Generic" e.g. NZ fire brigade panel, LED mimic, etc.
•
Up to eight I/O matrix boards can be programmed as type "Fan control" if no other
I/O matrix boards are used for generic or zone control i.e. up to 32 fans can be
controlled and displayed in FT128.
•
A combination of any of the two previous options can be used if the maximum
number of each application is maintained.
In the generic application, each I/O matrix board can operate up to 48 LEDs (outputs) and
16 switches (inputs). All outputs and inputs can be configured individually via EBLWin.
The I/O matrix board can be used remotely, it requires 24V and COM loop in addition to
an application board.
Note: Jumper links JP1-JP3 are used to set the I/O matrix board number (0-3) and JP5-
JP6 are used to set the application type (generic, fan control or zone control). For more
details refer to the Technical / Programming manual and/or Technical Datasheet
TDS040.
4.2
AS1668 Fan Control Module
The fan control module is designed to meet the requirements of the Australian standard
AS1668.2, the front display is shown in Figure 4 below.
Each fan control module consists of an I/O matrix 4582 and display / control board
SUB902. Each module can control and indicate the status of up to 4 different fans. Up to
8 x AS1668 fan modules can be used to provide 32 fan interfaces if no other Expansion
Boards or 4582 are used in different applications.

In the new 19" rack format, the I/O matrix circuit is incorporated into the AS1668 fan control and display board as well as zone
control board, new subassemblies are SUB1024 and SUB1023 respectively.
