IRIS/SIMPO Repeater TFT - Addressable Fire Alarm Repeater Panel
– Installation & Programming Manual

3.2. Main Power Supply
Connect the external power supply unit 24V DC as observe the polarity of the connection. It is recommended to use
power supply unit with backup batteries to guarantee the operation of the Repeater in case of mains power supply
failure.
3.3. Redundant Network RS485
The Repeater panel is designed with option for connection in a redundant network with other SIMPO, iRIS8 and
Repeater panels (up to 64). The redundant network is based on RS485 interface.
The RS485 interface is built-in the Repeater panel. For operation in a common redundant network with other fire panels
they must be equipped with Redundant Network Module
– Figure 8. The Redundant network module is connected to
“NETWORK” interface connector on the fire panel PCB (interface module in iRIS8).
Note: The RS485 interface terminals are accessible after removing the left side cover of the enclosure box.
Figure 8
The following table represents the correspondence of Tx/Rx terminal connections for IN and OUT communication lines.
Observe the polarity of
the RS485 interface
connection!

The LED indication for RS485 interface
in both
Repeater and Redundant module has same meaning:
•
OUT
- Output communication
•
Central Commun.
- Panel-Module
communication
•
IN
- Input communication
In normal operation mode the LEDs are blinking.
In case of trouble with the communication line the
LES are lighting on.
