5.1 Network System Hardware Features

6820 panels can be networked to create a virtual system that is larger than 1,110 addressable points. Each additional provides another 1,110
addressable points to the network total. For example, a network of 17- 6820panels provides a maximum addressable point capacity of 18,870
points (1,110 x 17 = 18,870).
5.1.1 Panels
6820 and other applicable addressable panels can be linked together for common communications to the central station. "Sites" are used to
allow for individual or common annunciation across the link. Up to 17 sites can be activated and programmed for the link. This does not cre-
ate a peer-to-peer network and will not operate as one.
5.1.2 Wiring Options to Connect Panels
1. Fiber Optic Single Mode - must use the -NIC and -FSL for up to 30dB loss of signal separation. -FSL connects to the link using 9/125
micron single-mode fiber
2. Fiber Optic Multi-Mode - must use the -NIC and -FML for up to 8dB loss of signal separation. -FML connects to the link using
62.5/125 micron multi-mode fiber
3. Twisted Pair Copper Wire - must use the -NIC to provide up to 3,000 feet of separation.
All methods of panel connectivity can be used within the same linked system.
5.2 SK-NIC Connection Options
When linking a group of 6820 panels, you must use the SK-NIC to link the panels together. See Figure 5.1 and Figure 5.2, for internal
mounting or external mounting of SK-NIC option.
Use provided 2' cable
and wire in conduit.
