3 Planning
3.1 General considerations
If the panel is to be used in a networked system, be careful to plan properly before installing
any panels. Check:
–
whether the networked panels will be installed near each other or distributed over a
wider area
– whether or not any of the networked panels will be in different buildings
– 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).
For each panel, be careful to plan properly before installing any devices. 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).
3.2 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 enabled; as is Port 3 on the wired card (FPE-1000-NW).
Table 3.1 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 1 on the wired card and
Port 3 on the fiber optic card). This jumper allows Ground Fault Detection to be disabled for
this port. Recommended communication connection practice is to come out of one card and
in on the next. In cases where you are switching from a wired or fber optic card to a different
type of card, you must use the Ethernet port which should be OUT not IN which is the default.
Move the jumper on this card so that Ground Fault Detection is disabled at this end of the
connection (making it an Ethernet OUT). Remove the jumper from both pins and replace it on
only one pin so that it does not get misplaced in case Ground Fault Detection needs to be re-
enabled later.
3.3 Port supervision
Each peer-to-peer connection (cable) connected to a networking card port used for panel-to-
panel communication must be supervised. This supervision is selected by programming.
For programming information, follow the panel programming instructions in the
