Section 5: Common Communication Link
5.1 Hardware Features
5.1.1 Panels
The 6700 panel can be connected to other 6700 and addressable panels to create a link where one panel is designated as the communicator
for all the panels in the link. Up to 17 panels can be connected in the Common Communication Link. This does not create a peer-to-peer net-
work and will not operate as one.SK
Wiring Options to Connect Panels
The 6700 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.
1. Fiber-Optic Single Mode - 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 - Use the SK-NIC and SK-FM 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 3,000 feet of separation.
All methods of panel connectivity can be used within the same linked system.
5.2 Direct Connect Wiring Option
When linking in a group of 6700 panels, you must use the SK-NIC to link the panels together. See Figure 5.1 for external mounting of SK-
NIC option.
5.3 SK-NIC Wiring Options
Linking a group of6700 panels requires the use of a network interface card with each panel. The SK-NIC connects to other linked units using
unshielded, twisted-pair wiring or fiber-optic cable.
Use provided 2’ cable
and wire in conduit.
