  3. Noti-Fire-NetTM • A series of modules and products which allow a group of Fire Alarm Control Panels and other control equipment to connect forming a true peer-to-peer network. • Page 4

  4. Noti-Fire-NetTM • Equipment that connects to NOTI-FIRE-NET and communicates with other equipment using the network may be referred to as a network node. NOTI-FIRE-NET supports up to 103 nodes with a total capacity of 201,960 points. A node may be: • AM2020 Fire Alarm Control Panel • AFP1010 Fire Alarm Control Panel • NRT Network Reporting Terminal • AFP-200 with NAM-232 Module • INA Intelligent Network Annunciator • Page 4

  5. Media Interface Board • The Media Interface Board (MIB) provides the physical interface to the following medium which connects node together forming a network: • MIB-W - Two twisted pair wire ports • MIB-F - Two fiber optic cable ports • MIB-WF - One twisted pair port and one fiber optic cable port • Page 4

  6. Network Adapter Module • NAM-232 Provides a physical interface from the AFP-200 or AM2020/AFP1010 Analog Fire Panel through the EIA-232 data port to the Network • NAM-232W - Two twisted pair wire ports • NAM-232F - Two fiber optic cable ports • Page 5

  7. The Serial Interface Board • The Serial Interface Board (SIB-NET) connects an AM2020 or AFP1010 to the network through an MIB. • Each AM2020/AFP1010 requires a network node address and the SIB-NET permits communication between the AM2020/AFP1010 and other nodes on the network. • The SIB-NET also provides an EIA-232 and EIA-485 output circuits for other external devices. • Page 5

  8. The NRT-NET Board • The NRT-NET interface card and a MIB allow the Network Reporting Terminal (NRT) to communicate with the network. • The NRT-NET interface card plugs directly into a computer expansion slot located on the NRT mother board. • The MIB plugs onto the NRT-NET card to complete the network interface. • Each NRT requires a network node address. • Page 5

  9. The Repeaters (RPTs) • The Repeaters (RPT) boost data signals between network nodes extending communication distances. • RPT-W supports twisted pair wire • RPT-F supports fiber optic cable • RPT-WF supports twisted pair wire and fiber optic cable. • Page 5

  12. NOTI-FIRE-NET Specifications • When designing the wiring layout of a NOTI-FIRE-NET system, the following distance limitations must be considered: • 1.The length of each individual twisted pair or fiber optic segment is limited. A segment is either point-to-point of two nodes/repeaters or bus connection (wire only) containing three or mode nodes. • Page 7

  14. NOTI-FIRE-NET Specifications • NOTI-FIRE-NET distance limitations : • Twisted Pair circuits • The length of cable for each segment in the system must be within the range specified in Table 1.5-1. If the distance required is greater than permitted, a RPT must be inserted into the circuit. • Cable type should be selected to satisfy the code requirement specific to a particular application. • Note: This table has been expanded to include more wire sizes and styles since original preparation. See the table in the manual for more information. • Page 7

  19. NOTI-FIRE-NET Specifications • NOTI-FIRE-NET distance limitations : • Fiber Optic circuits • Cable attenuation between two nodes must not exceed a 10 dB limit. Distances greater than permitted require a repeater module inserted at intervals less than or equal to 10 dB. • To determine loss, find the rated dB loss per foot and multiply by the distance required, and add the dB loss for each connector and splice • Loss = ((loss/ft) X (length in feet)) + conn. loss. • Page 10

  20. NOTI-FIRE-NET Specifications • NOTI-FIRE-NET distance limitations : • 2. System path length is limited and determined by using Table 1.5-2. The path is defined as the distance of travel from one end of the network to the other, and is influenced by the number of MIB, NAM and RPT devices, and medium of the circuit path. • Page 10

  23. Minimum Requirements • An NRT or INA and a fire panel with initiating devices and notification appliances define the minimum system requirements for a NOTI-FIRE-NET. • For each AM2020/AFP1010 panel configured for NFPA 72-1993 Local Fire Alarm System a CMX module set at Loop 1, address 96 with Type ID EVGA is also required. • Page 11

  24. NFPA Style 4 Configuration • Noti-Fire-Net is capable of communicating using NFPA Style 4 SLC. • 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 results in fragmentation of the network. • A single ground does not affect communication, but is detected. • Each fragment of the network reconfigures to permit communications among nodes within the fragment. • Page 12

Bus connections should be no longer than 100’ within conduit or the same enclosure.

Communication is partially lost between these nodes These nodes continue to communicate These nodes continue to communicate Break A B A B A B A B Network Node Network Node Network Node Network Node NFPA Style 4 Configuration • In an NFPA Style 4 fiber-optic system, a single break will result in loss of communication between network nodes within the fragment of the network that can only receive signals from the other fragment. • Page 13

  27. NFPA Style 7 Configuration • Noti-Fire-Net is capable of communicating using NFPA Style 7 SLC. • 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. • A single ground does not affect communication, but is detected. • Style 7 operation may be achieved using fiber optic cable or mixed media (wire and fiber) • Page 12

  29. A B A B A B A B Network Node or RPT Network Node or RPT Network Node or RPT Network Node or RPT Configuration Definitions • Point-to-Point wiring configuration is defined as a twisted-pair segment with only two nodes/ repeaters attached to it. Terminating resistors are required at each end of every segment, and are built into each MIB, NAM-232, and RPT. • Page 14

  30. Configuration Definitions • Characteristic Impedance in a Point-to-Point Configuration • Wire segment of each connection is a transmission line. • Physical construction of the cable used 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 segment. • Page 14

  32. A B A B A B A B Network Node or RPT Network Node or RPT Network Node or RPT Network Node or RPT Bus Configuration • A bus wiring configuration is defined as a twisted pair network with more than two nodes. Terminating resistors are only needed on the first and last node of the bus pair, all other resistor must be removed. • Page 16

  33. Bus Configuration • In a bus configuration, more than one node /repeater shares the same circuit. • A fault anywhere along the bus will affect the rest of the nodes/ repeaters on the bus. • Because of their inherent weakness, bus configurations are best employed for wiring between nodes/repeaters local to each other (within the same cabinet or room). • Page 16

  34. Bus Configuration • Wiring Distances Between Nodes on a Bus • In a bus configuration, data is shared between all ports on the twisted pair, thereby reducing the allowable transmission distance to a maximum of 100 ft. • Page 16

  35. Bus Configuration • Characteristic Impedance in a Bus Configuration • The wire segment for 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. • Always make bus connections at the module terminals provided. • Do not make branch connections at other points. • Page 16

  37. Terminating Point-to-Point and Bus Configurations • Both point-to-point and bus twisted wire pair configurations require end-of-line termination at each end of the respective circuit. • Whereas a point-to-point circuit has a terminating resistor at each node/repeater port, a bus circuit spans multiple nodes/repeaters, with termination only at the outer edges of the circuit. • Page 18

  38. Terminating Point-to-Point and Bus Configurations • Terminating resistors are present on all MIBs, NAMs, and repeaters. The terminating resistor on the first and last nodes/repeaters of a wire segment must remain intact. The terminating resistors on all the other nodes/repeaters connected to the same bus segment must be cut and removed from each board. • Page 18

  43. Network Wiring Ground Fault Detection • Twisted pair communications links between nodes can be isolated through the MIB/ NAM transformer coupling, so a single ground fault has no effect on circuit operation. • Ground fault of the isolated link is not necessary unless required by LAHJ. • Ground fault detection from a node power supply may be fed-through or disabled at the MIB/NAM. • Page 20

  45. Network Wiring Ground Fault Detection • Ground fault circuit operation: • Ground fault detection may be provided by a FACP node which is powered by a MPS-24A or by an AFP-200 connected with a NAM-232. • INA and NRT cannot provide ground fault detection. Switches SW1 and SW2 on the INA or NRT must always be off. • Page 20
