Teletek electronics iRIS4 - 4.5. Connection of a Repeater Panel

iRIS4 - Addressable Fire Alarm Panel – Installation Manual

4.4.4. Redundant Network Module
The iRIS4 addressable fire alarm panel is designed with option for connection in a redundant network with other iRIS4,
iRIS8, SIMPO and IRIS/SIMPO Repeater panels (up to 64). The redundant network is based on RS485 interface.
The Redundant Network Module is an additional interface board, sold separately. The module is mounted to Network
connector of iRIS4 main control module PCB. The additionally mounted PCB should be fixed with screws to the metal
cover. The maximum cable length between two network modules and/or repeater panel should not exceed 1000m.
Figure 29
To use the redundant module, the installer must set the Network type for all connected panels as “RS485” in installers
menus (access level 3): System-Programming-Panel-Network-Network Settings-Network Type.
4.5. Connection of a Repeater Panel
The Repeater panel is a control panel for remote indication of fire alarm, fault, trouble, warning and other type of events,
reported from iRIS4 and other Teletek Electronics addressable panels connected into one common network. The
IRIS/SIMPO Repeater can operate only as a part of a network. It repeats the status of the connected fire panels and
informs for events.
Up to 64 panels can operate in a single network, including IRIS/SIMPO Repeater, iRIS8, iRIS4 and SIMPO fire alarm
panels. According the used Repeater model, the connection in the network between the panels can be realised via
RS485 interface or LAN:
• Model IRIS/SIMPO Repeater TFT – RS485 interface or LAN
• Model IRIS/SIMPO Repeater – RS485
Only one type of connection can be used in a single network.
RS485 Interface
The RS485 interface is built-in the repeater panel and the connection with iRIS4 is realized via Redundant network
module (Figure 30) connected to “NETWORK” connector on the main control module PCB.
The following table represents the correspondence of Tx/Rx terminal connections for IN and OUT communication lines.
