5.1 Hardware Features

6820/EVS panels can be networked to create a virtual system that is larger than 1,110 addressable points. Each additional 6820/EVS pro-
vides another 1,110 addressable points to the network total. For example, a network of 17- 6820/EVS panels provides a maximum
addressable point capacity of 18,870 points (1,110 x 17 = 18,870 SK devices).
5.1.1 Panels
6820/EVS 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.
5.1.2 Wiring Options to Connect Panels
1. Fiber Optic Single Mode - must use the SK-NIC and SK-FSL for up to 30dB loss of signal separation. SK-FSL connects to the link
using 9/125 micron single-mode fiber
2. Fiber Optic Multi-Mode - must use the SK-NIC and SK-FML for up to 8dB loss of signal separation. SK-FML connects to the link
using 62.5/125 micron multi-mode fiber
3. Twisted Pair Copper Wire - must use the SK-NIC to provide up to 3000 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/EVS's 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.
