Section 5: Networking
5.1 Network System Hardware Features
5.1.1 Networked Panels
The IFP-75 panel can be networked to create a virtual system that is larger than 150 addressable points. Each additional IFP-75 provides
another 150 addressable points to the network total. For example, a network of 32 IFP-75 panels provides a maximum addressable point
capacity of 2,550 points (150 x 32= 4,800 IDP or SK devices).
Wiring Options to Connect Networked Panels
A networked site is a logical group of IFP-75 panels that behave as though the logical group is one large control panel. Each building is
referred to as a “site.” All panels in a site operate as a single panel. The control functions like reset, silence and alarm activation operate
across the entire site. There can be one or more logical sites within a networked system. Taken to the extreme, the maximum number of sites
within a network system is limited to the number of panels in the network with each site comprised of only one panel.
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 network
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 network 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 networked system.The network architecture provides true peer-to-peer capa-
bility allowing network survivability for all hardware that remains operational in the event of partial system failure.
5.2 Direct Connect Wiring Option
When networking in a group of IFP-75 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
Networking a group of IFP-75 panels requires the use of a network interface card with each panel. The SK-NIC connects to other networked
units using unshielded, twisted-pair wiring or fiber-optic cable.
Use provided 2’ cable
and wire in conduit.
