11.9 Redux module [DE]
The Redux module serves for data transmission and power supply redundancy of a
fire brigade indication panel (FAT).
The data cable is connected to the control panel's RS485 interface.
If one of the connection lines to the FAT fails due to a short-circuit or open line,
complete functionality is ensured. The line fault is signaled by the fault relay of the
Redux module which drops in case of a fault.
The fault output of the Redux module is wired to an input of the periphery board
and assigned to a 'Technical zone' of type 'Fault sub-system'.
Assigning 'Technical zone' to 'Periphery board'
1. Create a 'Technical zone' using the 'Fault sub-system' template.
2. Assign the 'Technical zone' to an 'I/O' element / event category 'Input' in the
'Hardware tree'. Link [➙ 76]
