ETWORK IRING
The Noti-fire-net network wiring system is to be wired in 1.5mm
The network cable can run up to 1 klm between nodes (Each Fire Panel is a Node). For optimal
performance, Noti-fire Net should be run in a closed loop (style 6), however, Noti-fire-Net does have
the ability to run in an open-ended format (style 4). The cable is terminated on to a network card
(see the Noti-fire-Net manual for termination data).

The 1010/2020 has multiple RS-232 and RS-485 circuits, the illustrations below show the positions
and where to find them.
RS-485 circuits used for Annunciators wired outside of the Panel, are to be wired in 2 core Twisted
Shielded. Total RS485 run should not exceed 1.5 k's in length. A second 2-core twin for 24Vdc is
also required for powering the Annunciators. (The last Annunciator must have a 120-ohm resistor
fitted across the RS-485 circuit). The shield must be earthed at the panel end, to the nearest earth
point immediately inside the Panel.
RS-485 circuits used for Terminal mode operation (LCD-80tm direct from the DIA) wired outside the
Panel, are to be wired in 4 core Twisted Shielded, or 2 x 2 core Twisted Shielded, and 2 core twin
for power supply requirements if needed. (The last Annunciator must have two 120-ohm resistors
fitted across the RS-485 circuits) The shields must be earthed at the Panel end, to the nearest earth
point immediately inside the Panel.
RS-232 circuits used for printer's etc, wired outside of the Panel, are to be wired in Twisted Shielded
wiring and not to exceed 15 mtrs in length. The shield must be earthed at the Panel end, to the
nearest earth point immediately inside the Panel.
The following illustrations indicate the connection points for RS-485 and RS-232 circuits.
