2 Planning information
2.1 General considerations
Notice!
The FPA-1000’s network (created by using our network cards) is a peer-to-peer network that
is considered to be a signaling line circuit (SLC). As such, it cannot be interconnected to any
other network. Such interconnection can result in the failure of the network panels to
properly communicate with each other.
Before installing any panels to be used in a networked system, be careful to plan properly.
Determine whether to use a Class X or Class B topology for the network connections (see
Connection, page 9 ). The type of cards needed to connect a pair of panels depends on the
intended interconnection method (Ethernet, fiber optic, or wire). Factors to consider when
choosing an interconnection method include:
–
Whether the networked panels are to be installed near each other or distributed over a
wider area. An Ethernet connection has a maximum length of 328 ft. (100 m). A wired
connection can be up to 10 times as long (3280 ft. [1000 m]). However, in a harsh
electrical environment, shielded or twisted-pair wire or fiber optic cable can be necessary
– Whether any of the networked panels are to be in different buildings. Fiber optic cable is
recommended for this application since it is less susceptible to electrical noise and is
suitable for longer distances (up to 6560 ft. [2000 m])
– The types and numbers of Networking Cards needed
– Interconnection requirements including the maximum allowable cable lengths which
depend on the intended interconnection method (Ethernet, fiber optic cable, or wire)
Before installing any devices to be connected to any networked panel, be careful to plan
properly. Check:
–
The compatibility and number of devices to be connected
– The battery capacity needed
– The wiring requirements including the maximum allowed cable length
– The installation requirements according to this Installation and Operation Guide , NFPA 72,
Local Codes, and the Authority Having Jurisdiction (AHJ)
2.2 Ground fault detection
Each networking card has a specific terminal or terminals that are Ground Fault Detection
enabled. As indicated by the checked boxes in the following table, Port 1 on all three
networking cards is ground fault configurable, as is Port 3 on the wired card (FPE‑1000‑NW).
Port -NE -NF -NW
1 Ethernet IN Ethernet IN Wired IN
2 Ethernet OUT Fiber IN Wired OUT
3 Ethernet Fiber OUT Ethernet IN
Table 2.2: Network Port Identification
For Ground Fault Detection to work properly, one and only one end of a communication
connection (cable) joining two networking cards must be Ground Fault Detection enabled. To
facilitate this, the wired card (FPE‑1000‑NW) and the fiber optics card (FPE‑1000‑NF) each
have a jumper located near the back of the Ethernet IN port (Port 3 on the wired card and
Port 1 on the fiber optic card). This jumper allows Ground Fault Detection to be disabled for
