ion Association Standard 72 (NFPA 72),cturer's recommendations, State and local codes, andommendations contained in the Guide for Proper Useem Smoke Detectors, which is made available at no to all installing dealers. A study by the Federal Emer-Management Agency (an agency of the United Statesment) indicated that smoke detectors may not go off iny as 35% of all fires. While fire alarm systems are de-to provide early warning against fire, they do not guar-arning or protection against fire. A fire alarm system

detectors may not sense fire where smoke cannothe detectors such as in chimneys, in or behind walls, onr on the other side of closed doors. Smoke detectors

ay not sense a fire on another level or floor of a build-second-floor detector, for example, may not sense aor or basement fire.

ers such as closed or partially closed doors, walls, orneys may inhibit particle or smoke flow.

ke particles may become "cold," stratify, and not reacheiling or upper walls where detectors are located.

ke particles may be blown away from detectors by airts.

ke detectors may be drawn into air returns beforeing the detector.

ount of "smoke" present may be insufficient to alarmdetectors. Smoke detectors are designed to alarm at levels of smoke density. If such density levels are not by a developing fire at the location of detectors, thers will not go into alarm.

detectors, even when working properly, have sensingns. Detectors that have photoelectronic sensing

detectors cannot be expected to provide adequate of fires caused by arson, children playing withs (especially in bedrooms), smoking in bed, and violentons (caused by escaping gas, improper storage ofble materials, etc.).

Heat detectors do not sense particles of combustion andalarm only when heat on their sensors increases at a prede-termined rate or reaches a predetermined level. Rate-of-riseheat detectors may be subject to reduced sensitivity over timFor this reason, the rate-of-rise feature of each detectorshould be tested at least once per year by a qualified fire protection specialist. Heat detectors are designed to protectproperty, not life.

IMPORTANT! Smoke detectors must be installed in thesame room as the control panel and in rooms used by the sytem for the connection of alarm transmission wiring, communcations, signaling, and/or power. If detectors are not so lo-cated, a developing fire may damage the alarm system, crip-pling its ability to report a fire.

Audible warning devices such as bells may not alert peopleif these devices are located on the other side of closed orpartly open doors or are located on another floor of a buildingAny warning device may fail to alert people with a disability othose who have recently consumed drugs, alcohol or medication. Please note that:

• Strobes can, under certain circumstances, cause seizuresin people with conditions such as epilepsy.

• Studies have shown that certain people, even when theyhear a fire alarm signal, do not respond or comprehend themeaning of the signal. It is the property owner's responsibity to conduct fire drills and other training exercise to makepeople aware of fire alarm signals and instruct them on theproper reaction to alarm signals.

• In rare instances, the sounding of a warning device cancause temporary or permanent hearing loss.

A fire alarm system will not operate without any electricalpower. If AC power fails, the system will operate from standbbatteries only for a specified time and only if the batterieshave been properly maintained and replaced regularly.

Equipment used in the system may not be technically com-patible with the control. It is essential to use only equipmentlisted for service with your control panel.

Telephone lines needed to transmit alarm signals from apremise to a central monitoring station may be out of serviceor temporarily disabled. For added protection against tele-phone line failure, backup radio transmission systems are recommended.

The most common cause of fire alarm malfunction is inade-quate maintenance. To keep the entire fire alarm system inexcellent working order, ongoing maintenance is required pethe manufacturer's recommendations, and UL and NFPA standards. At a minimum, the requirements of Chapter 7 of NFPA72 shall be followed. Environments with large amounts ofdust, dirt or high air velocity require more frequent mainte-nance. A maintenance agreement should be arrangedthrough the local manufacturer's representative. Maintenancshould be scheduled monthly or as required by National and/or local fire codes and should be performed by authorized prfessional fire alarm installers only. Adequate written recordsof all inspections should be kept.

While a fire alarm system may lower insurancerates, it is not a substitute for fire insurance! Alarm System Limitations

General Description

Technic

General DescriptionNOTI•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 NodesEquipment that connects to NOTI•FIRE•NET™ and communicates with other equipment using the network may be referred to as a network node. The network supports communications over twisted pair wire and fiber optic media. A combination of both wire and fiber may exist in the same network. NOTI•FIRE•NET™ supports up to 103 nodes with a total capacity of 201,960 points. The following may all be network nodes:

• AM2020/AFP1010 Fire Alarm System with a Network Serial Interface Board (SIB-NET) installed - The AM2020/AFP1010 FACP collects information about modules and peripherals connected to the network and makes this information accessible to all nodes connected to the network. Information from the panel may include the following signals: fire alarm, security alarm, trouble, and supervisory.

• AM2020/AFP1010 Fire Alarm System with a Network Adaptor Module (NAM-232) - The AM2020/AFP1010 occupies a single node address on the network. This configuration has limited capability. Functions are limited to the display of signals at an INA or NRT, network acknowledge, silence, and reset functions. Other features such as cooperative-control-by-event, read status, alter status, etc. are not supported in this configuration. Use of the NAM-232 prevents use of a primary CRT at the panel.

• AFP-200 or AFP-300/AFP-400 with a Network Adaptor Module (NAM-232) - The AFP-200 or AFP-300/AFP-400 occupies a single node address on the network similar to an AM2020 or AFP1010. The NAM-232 connects to the AFP-200 or AFP300/AFP-400 through the EIA-232 serial communications port. The network has the ability to send acknowledge, signal silence, drill, and reset commands to the AFP-200 or AFP-300/AFP-400. AFP-200 or AFP-300/AFP-400 zones may be used to activate other network node devices. Some NRT and INA functions are not supported in this configuration. Use of the NAM-232 prevents use of a printer or CRT at the panel on the AFP-200.

• Network Reporting Terminal (NRT) - The Network Reporting Terminal (NRT) is a computer-based platform that allows the user to program network nodes (systems), display network information, and break the network into desirable groups of nodes. The NRT can perform resets, signal silence, and acknowledge on sets of nodes. The NRT also contains a history buffer which can record events and actions which have occurred in the network. It works with NOTI•FIRE•NET™ software versions up to and including Software Version 2.8.

• Network Control Station (NCS) - The Network Control Station (NCS) is similar to the NRT, providing a PC-based graphical interface for monitoring and controlling activity of multiple nodes on a network. It allows the user to program network nodes, display network information, and break the network into desirable groups fo nodes. It can perform resets, signal silence, and acknowledge on sets of nodes. It also contains a history buffer which can record events and actions that have occurred in the network. It works with NOTI•FIRE•NET™ Software Version 3.0.

• Intelligent Network Annunciator (INA) - The Intelligent Network Annunciator (INA) can display and store network information. The INA can perform resets, signal silence, and acknowledge on sets of nodes. The INA has EIA-232 printer and CRT interfaces used to record/display network status, and an EIA-485 ACS interface.

Network Interface BoardsThe Media Interface Board (MIB) provides a physical communication interface to the following medium which connects nodes together forming a network:

• Twisted Pair Wire - MIB-W

NOTI•FIRE•NET™ PN 50257:E 7/5/01 5


Service Provided

Technic

• 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.

The NAM-232 provides a physical communication interface from the AFP-200, AFP-300/AFP-400, AM2020/AFP1010 Analog Fire Panel to the following communication media which connect nodes together forming a network:

• Twisted Pair Wire NAM-232W

• Fiber Optic Cable NAM-232F

The Serial Interface Board for NOTI•FIRE•NET™ (SIB-NET) connects an AM2020/AFP1010 to the network through a MIB and permits communication between the AM2020/AFP1010 and other nodes on the network. The SIB-NET supports all of the same functions as the SIB-2048A; i.e. Annunciator Control System (ACS), printers, and CRTs.

Each AM2020/AFP1010 requires a network node address.

The NRT-NET interface card and the MIB allow the NRT and NCS to communicate with the network. The NRT-NET interface card plugs directly into a computer expansion slot located on the NRT and NCS. The MIB, which supports the physical connection to the network, plugs onto the NRT-NET card to complete the network interface. Each NRT or NCS requires a network node address.

The Repeaters (RPT) boost data signals between network nodes extending communication distances. The RPT-W supports twisted pair wire, the RPT-F supports fiber optic cable, and the RPT-WF supports twisted pair wire and fiber optic cable.

Service ProvidedNOTI•FIRE•NET™, when properly configured, is suitable for use as a Protected Premises Fire Alarm System as defined in the National Fire Protection Association (NFPA) 72 documentation.

Overall Limitations

Technic

Overall LimitationsWhen 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 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. As illustrated in Figure 1, Example 1 segments 1, 2, and 3 are point-to-point circuits and Example 2 is a bus circuit encompassing five nodes. The procedures differ to determine the maximum permissible segment length for a twisted pair and a fiber-optic segment. The following paragraphs detail each procedure.

• Twisted Pair CircuitsThe length of cable for each segment in the system must fall within the range specified in Table 2. If the distance required for a circuit segment is greater than permitted, a Repeater module (RPT-W) must be inserted into the circuit at intervals less than, or equal to, the length restriction.

Cable type should be selected to satisfy the code requirements specific to a particular application. Refer to Table 2 through Table 4 for descriptions of specific cable types used with NOTI•FIRE•NET™.

Figure 1 Circuit Wiring Layout

Note: The use of more than one type of cable within any point-to-point or bus connection is not permitted. When utilizing existing cable, be sure to eliminate any cable branches or spurs.

• Fiber Optic CircuitsThe attenuation of cabling between two nodes/repeaters (fiber optic circuits are point-to-point) must not exceed a 8 dB limit. If the distance required for a circuit segment is greater than permitted, a Repeater module (RPT-F) must be inserted into the circuit at intervals less than, or equal to, the 8 dB attenuation length restriction.

Attenuation Determination:

Find the rated dB loss per foot within the cable manufacturer's specifications. Determine the total attenuation between the two nodes/repeaters due to the cable.

Loss = (loss/ft.) x (length in feet)

Establish the dB loss for each connector and splice. Sum all the losses.

NOTE: In the event of a panel failure at a wire node, the data is not regenerated locally. The node may be manually bypassed using the NBB-1 Assembly. In this case, the total length of wire becomes the sum of both lengths of wire between operating nodes. If the total length exceeds the maximum allowable length for a given threshold, the network may lose communication. Separately powered repeater(s) may be employed at each node in a point-to-point connection to ensure data regeneration.



Minimum Requirements

Technic

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.

2. 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). The length is influenced by the total number of MIB, NAM-232, RPT devices, and medium along the circuit path. Refer to Figure 3 for system limitations.

NFPA Style 4 ConfigurationsNOTI•FIRE•NET™ is capable of communicating using an NFPA Style 4 SLC (refer to Figure 4). 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 communication among the nodes within the fragment.

Figure 4 Style 4 Configurations

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 (refer to Figure 5). In Figure 5, the fragment to the left of the break cannot receive information from the fragment to the right of the break. However, the fragment to the right of the break can receive information from the fragment to the left of the break.

Figure 5 Fiber-Optic Style 4 System Break

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 enclosure.

These two nodes continue to communicate with each other.

These two nodes continue to communicate with each other. However, they will not transmit to the first two nodes.

NFPA Style 7 ConfigurationsNOTI•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).

Figure 6 Style 7 Configurations

Configuration DefinitionsThe 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.



Configuration Definitions

Technic

Characteristic Impedance In a Point-to-Point ConfigurationThe 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.

If a network employs point-to-point wiring only, a separate pair of wires must be run between each node/repeater port (refer to Figure 7).

Figure 7 Point-To-Point Configuration

• Bus ConfigurationA bus wiring configuration is defined as a twisted pair network with more than two nodes. Terminating resistors are only needed for the first and last nodes of the bus configuration, all other terminating resistors must be removed.In a bus configuration, more than one node/repeater shares the same circuit (refer to Figure 8). 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).

• 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 feet (refer to Table 2 through Table 4).

Figure 8 Bus Configuration (NFPA Style 4 Only)

Characteristic Impedance In a Bus ConfigurationThe 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. Always make bus connections at the module terminals provided. Do not make branch connections at other points.

A combination configuration can be used to distribute the network circuit from a central facility, saving on wiring run lengths. In Figure 9, a repeater was bus-wired to two existing nodes in each central facility (located within the same room) to support point-to-point connections to the remaining buildings in the system.

Figure 9 Combination Wiring

Terminating Point-To-Point and Bus ConfigurationsBoth point-to-point and bus configurations require end-of-line resistor termination at each end of the respective circuit. Whereas a point-to-point circuit has a terminating resistor at each node/repeater port (refer to Figure 10), a bus circuit spans multiple nodes/repeaters, with termination only on the associated port of the first and last (end) nodes on the segment (refer to Figure 11).

• Terminating ResistorsTerminating resistors are present on each MIB-W, MIB-WF, NAM-232W, RPT-W, and RPT-WF (refer to Table 5). The terminating resistor on the first and last node/repeater 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 (refer to Figure 10 and Figure 11).

Network Wiring Ground Fault Detection

Technic

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. For this reason, ground fault detection for the isolated link is not necessary unless required by the Authority Having Jurisdiction.

Ground fault detection from a node power supply may be fed-through or disabled through switches on the MIB-W, MIB-WF, NAM-232W, and RPT-W (refer to Figure 12). Set switch to ENABLE for ground fault detection.

Figure 12 Ground Fault Switches

Ground fault detection may be provided by a fire panel or INA node on the network which is powered by a Main Power Supply (MPS-24A), or an AFP-200/AFP-300/AFP-400 connected to the network through a NAM-232.

The following paragraphs highlight ground fault detection considerations for point-to-point and bus wire configurations. In the examples that follow, the MIB-WF or NAM-232W may be used in place of the MIB-W.

Point-To-Point ConfigurationIn a point-to-point configuration without repeaters, enable ground fault detection in only one of the two nodes. In Figure 13, the left node provides the ground fault detection, and thus, must be an AFP-200/AFP-300/AFP-400, or AM2020/AFP1010/INA with an MPS-24A Main Power Supply. SW2 is set to the ON position to enable ground fault feed-through detection on the left MIB-W Port B. The corresponding Port A switch of the right MIB-W is set to the OFF position, disabling ground fault detection feed-through from the node on the right. The node on the right can be any network node.

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).

Note: Refer to the Network Adaptor Module (NAM-232) Manual when employing the NAM-232W in place of the MIB-W. See Table 1 on page 6 for document numbers.

• EXAMPLE 1: In this example, the node on the left provides the ground fault detection, and thus, the node must be an AFP-200, AFP-300/AFP-400, or AM2020/AFP1010/INA with an MPS-24A Main Power Supply. SW2 (Port B) of the MIB on the left is set to the ON position to enable ground fault detection on Port B. The RPT-W pass-through switch (SW3) is ON, allowing the left node to provide ground fault detection for the two point-to-point wire connections on the left and right of the repeater. The Port A switch on the right MIB-W is set to the OFF position, disabling ground fault detection feed-through from the node on the right. The node on the right can be any network node.

Figure 14 Point-To-Point (EXAMPLE 1)

• EXAMPLE 2: By setting the pass-through switch (SW3) on the RPT-W to the OFF position, both nodes may provide their own ground fault detection (refer to Figure 15). The left node provides ground fault detection up to the RPT-W, and thus, must be an AFP-200/AFP-300/AFP-400, or AM2020/AFP1010/INA with an MPS-24A Main Power Supply. SW2 (Port B) is set to the ON position to enable ground fault detection pass-through on the left MIB-W.

The Port A switch on the right MIB-W is also set to the ON position, providing ground fault detection pass-through up to the RPT-W. This node must also be an AFP-200/AFP-300/AFP-400,or AM2020/AFP1010/INA with an MPS-24A Main Power Supply.




Technic

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.

Figure 16 Maximum Point-To-Point Series Repeater Ground Fault Feed-Through Configuration (EXAMPLE 3)

Bus ConfigurationIn a bus configuration, as in point-to-point, only one node can provide ground fault detection along the bus. The primary difference is that one node can provide ground fault detection for multiple nodes along the bus (refer to EXAMPLE 1 and 2).

Note: Refer to the Network Adaptor Module (NAM-232) manual when employing the NAM-232W in place of the MIB-W.

• EXAMPLE 1: The node second from the right in Figure 17 provides the ground fault detection, and thus, must be an AFP-200/AFP-300/AFP-400, or AM2020/AFP1010/INA with an MPS-24A Main Power Supply. SW1 (Port A) is set to the ON position to enable ground fault detection feed-through from the MIB on this node. All other nodes have ground fault detection on the MIB disabled. This includes the node on the far left of the figure, since ground fault detection has been passed through the RPT-W from the node second from the right.

Figure 17 Bus (EXAMPLE 1)




Technic

Note: On remotely powered nodes, ground fault detection is processed through the main power supply (MPS-24A or MPS-24B).

• EXAMPLE 2: If the repeater pass-through switch is set to the OFF position (refer to Figure 18), isolating the three wires on the right from the wires on the left, separate ground fault detection circuits must be fed through. The node second from the right continues to provide ground fault detection up to the RPT-W Port B, and must be an AFP-200, AFP-300/AFP-400, or AM2020/AFP1010/INA with an MPS-24A Main Power Supply. The node on the far left of the figure provides ground fault detection up to the RPT-W Port A, and also must be an AFP-200, AFP-300/AFP-400, or AM2020/AFP1010/INA with an MPS-24A Main Power Supply.

FCC Considerations

Technic

FCC Considerations In order to comply with FCC regulations regarding radio frequency missions, a ferrite cylinder (NOTIFIER PN 29087) must be installed on every twisted pair circuit connected to a MIB-W (Two cylinders included) and MIB-WF (one cylinder included).

Installation on the NRT/NCSThe following steps must be completed to install the ferrite cylinder on the NRT/NCS (refer to Figure 19):

1. Thread the twisted pair (two pairs for a bus connection) through the ferrite cylinder.

2. Slide the cylinder along the pair(s) toward the MIB on the back of the NRT/NCS so that the closest edge of the cylinder is no more than 3 inches away from the terminal connection block.

3. Secure the ferrite cylinder to the wiring with the supplied tie wrap at each end of the cylinder.

4. If used, repeat for the remaining twisted pair(s) on a MIB-W (second port).

Figure 19 Installation of the Ferrite Cylinder on the NRT/NCS

Installation on the INA and SIB-NETThe following steps must be completed to install the ferrite cylinder on the INA and SIB-NET (refer to Figure 20):

1. Thread the twisted pair (two pairs for a bus connection) through the ferrite cylinder.

2. Slide the cylinder along the pair(s) toward the entrance point on the cabinet (not toward the MIB) so that the edge of the cylinder and the cabinet are separated by no more that three inches.

3. Secure the ferrite cylinder to the wiring with the supplied tie wrap at each end of the cylinder.

4. If used, repeat for the remaining twisted pair(s) on a MIB-W (second port).
