NFPA Style 7 Configurations

NFPA Style 7 Configurations

NOTI•FIRE•NET™

is capable of communicating using an NFPA Style 7 SLC (refer to Figure

6). Under this style of operation, a single open, wire-to-wire short, wire-to-wire short and open,
wire-to-wire short and ground, or open and ground will not result in fragmentation of the network.
Communication will continue throughout any of the aforementioned circumstances, while the
system displays a trouble condition. A single ground does not affect communication, but is
detected. Style 7 operation may also be achieved using fiber optic cable or mixed media (wire and
fiber).

Configuration Definitions

The following configurations are defined:

•

Point-To-Point Configuration

A point-to-point wiring configuration is defined as a twisted-pair wire segment with only two
nodes/repeaters attached to it. Terminating resistors are required at each end of every twisted-
pair wire segment and are built into each MIB-W, MIB-WF, NAM-232W, RPT-W, and RPT-
WF. Refer to "Terminating Point-To-Point and Bus Configurations" on page 15 for more
information.

In a point-to-point configuration, two nodes/repeaters are interconnected by a single circuit
that is terminated at each port (refer to Figure 7).

Note:

Bus connections are

not permitted in a Style 7
system.
