Page 5: General Description
General Description General Description NOTI•FIRE•NET™ is a series of modules and products which allow a group of Fire Alarm Control Panels (FACPs) and other control equipment to connect, forming a true peer-to-peer network. Network Nodes Equipment that connects to NOTI•FIRE•NET™ and communicates with other equipment using the network may be referred to as a network node. -
Page 6: Service Provided
Service Provided • Fiber Optic Cable - MIB-F • Twisted Pair Wire and Fiber Optic Cable MIB-WF Each MIB has two communication ports. The MIB-W has two twisted pair wire ports, the MIB-F has two fiber optic cable ports and the MIB-WF has one twisted pair wire and one fiber optic cable port. -
Page 7: Overall Limitations
Overall Limitations Overall Limitations When designing the wiring layout of a NOTI•FIRE•NET™ system, the following distance limitations must be considered: The length of each individual twisted pair or fiber optic network communication circuit segment is limited. A segment is defined as either a point-to-point connection with two nodes/ repeaters, or a bus circuit encompassing multiple nodes. - Page 8 Overall Limitations Permissible Single Twisted Pair Range Data Threshold: Cable Manufacturer, Part (In Feet) For Each Cable Segment All Nodes And/Or Number, and Number of Gauges/ Manufacturer's Specifications Repeaters On A Point-To-Point Bus Configuration Conductors Cable Segment 2 Nodes/Repeaters 3 to 7 Nodes/Repeaters ACE Wire 61401SLL, 14 AWG, FPLP, High:...

Page 10: Minimum Requirements
Minimum Requirements Total the attenuation factors obtained in steps a. and b. This will provide an approximate attenuation total. The actual attenuation can be measured end-to-end with fiber optic industry standard equipment using a test wavelength of 850 nanometers. The system path length is limited. The system path length is defined as the distance a signal would have to travel from one end of the network to the other end (refer to Figure 2). -

NFPA Style 4 Configurations • NRT requirements consist of an NRTT-M17W, NRTT-M17F, NRTT-M17WF, NRTT-M21W, NRTT-M21F, or NRTT-M21WF: each consists of a computer with wire and/or fiber configuration, a MON-17B or MON-21 monitor, and a PCLB-4. • NCS requirements consist of an NCS-M17W, NCS-M17F, NCS-M17WF, NCS-M19W, NCS-M19F, or NCS-M19WF: each consists of a computer with wire and/or fiber configuration, a MON-19, and the PCLB-5. - Page 12 NFPA Style 4 Configurations reconfigures to permit communication among the nodes within the fragment. Note: A wire-to-wire short here results in loss of communication between all four nodes/repeaters on this bus connection as well as fragmentation of the network. Bus connections should be no longer than 100 feet within conduit or located within the same...

Page 13: Nfpa Style 7 Configurations
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. -
Page 14: Characteristic Impedance In A Point-To-Point Configuration
Configuration Definitions Characteristic Impedance In a Point-to-Point Configuration The wire segment of each point-to-point connection is a transmission line. The physical construction of the twisted-pair cable used for a segment determines the characteristic impedance of that segment. To minimize unwanted data reflections, never mix more than one brand name, gauge, or type of wire within a point-to-point segment. -

Terminating Point-To-Point and Bus Configurations Characteristic Impedance In a Bus Configuration The wire segment of each bus connection is a transmission line. The physical construction of the twisted-pair cable used for a segment determines the characteristic impedance of that segment. To minimize unwanted data reflections, never mix more than one brand name, gauge, or type of wire within a bus segment. - Page 16 Terminating Point-To-Point and Bus Configurations Port A Port B RPT-W RPT-WF MIB-W MIB-WF NAM-232W Table 5 On-Board Terminating Resistors These point-to-point circuit segments are terminated at each node/repeater.

Page 17: Network Wiring Ground Fault Detection
Network Wiring Ground Fault Detection Network Wiring Ground Fault Detection Since the twisted pair communication link between adjacent nodes can be isolated from the nodes through the MIB/NAM-232 (transformer coupling), a single ground fault on one of the wires will have no effect on circuit operation. - Page 18 Network Wiring Ground Fault Detection Figure 13 Point-To-Point Ground Fault Detection If an RPT-W is employed, two ground fault detection schemes are possible within a point-to-point configuration. One or both nodes (refer to Figure 14 and Figure 15) may provide ground fault detection, depending on the number of repeaters and the setting of the repeater pass-through switch (SW3) at each repeater (refer to EXAMPLES 1 and 2).

Page 19: Bus Configuration
Network Wiring Ground Fault Detection Figure 15 Point-To-Point (EXAMPLE 2) • EXAMPLE 3: Ground fault detection feed-through is effective for a maximum of two serially connected (point-to-point) repeaters. Therefore, a maximum of five repeaters can be connected in series when ground fault detection is required. Figure 16 shows how the ground fault detection feed-through switches must be arranged in order to achieve this maximum configuration. - Page 20 Network Wiring Ground Fault Detection • EXAMPLE 2: If the repeater pass-through switch is set to the OFF position (refer to Figure Note: On remotely powered nodes, 18), isolating the three wires on the right from the wires on the left, separate ground fault ground fault detection detection circuits must be fed through.
