INSTALLATION & COMMISSIONING MANUAL - REVISION 1.0 - 19.FEB.2007
INSTALLATION
Data Loops
If the system includes mini-repeaters to allow remote viewing and control of the system, an RS422/485,
Fibre Optic or TCP/IP connection may be used.
For redundancy in the case of RS422/485 and Fibre Optic this can be wired in the form of a Loop, thus
protecting the Data Loop from interruptions or short circuits by creating a bi-directional communications
flow. If the panel loses communications with the repeater it will try via the opposite path.
RS422/485 may be used for distances of up to 1200m. For longer distances (up to 4,5km) Fibre Optic
Data connections should be used.
See page 15 for cable requirements for both types of installation.
NOTE:
Only 2 Mini-Repeaters should be powered from the Auxilliary supply output of the Junior
when the panel is equipped with 2 loops. Extra Mini-Repeaters should be powered by an
external 24V DC power supply.
