Notifier NOTI-FIRE-NET Manual

NFPA Style 7 Configurations
NOTI•FIRE•NET™ PN 50257:E 7/5/01 13
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.
