Precau-Lg.p65 01/18/2000
An automatic fire alarm system–typically made up of smoke
detectors, heat detectors, manual pull stations, audible warn-
ing devices, and a fire alarm control with remote notification
capability–can provide early warning of a developing fire.
Such a system, however, does not assure protection against
property damage or loss of life resulting from a fire.
The Manufacturer recommends that smoke and/or heat detec-
tors be located throughout a protected premise following the
recommendations of the current edition of the National Fire
Protection Association Standard 72 (NFPA 72),
manufacturer's recommendations, State and local codes, and
the recommendations contained in the Guide for Proper Use
of System Smoke Detectors, which is made available at no
charge to all installing dealers. A study by the Federal Emer-
gency Management Agency (an agency of the United States
government) indicated that smoke detectors may not go off in
as many as 35% of all fires. While fire alarm systems are de-
signed to provide early warning against fire, they do not guar-
antee warning or protection against fire. A fire alarm system
may not provide timely or adequate warning, or simply may not
function, for a variety of reasons:
Smoke detectors may not sense fire where smoke cannot
reach the detectors such as in chimneys, in or behind walls, on
roofs, or on the other side of closed doors. Smoke detectors
also may not sense a fire on another level or floor of a build-
ing. A second-floor detector, for example, may not sense a
first-floor or basement fire.
Particles of combustion or "smoke" from a developing fire
may not reach the sensing chambers of smoke detectors be-
cause:
• Barriers such as closed or partially closed doors, walls, or
chimneys may inhibit particle or smoke flow.
• Smoke particles may become "cold," stratify, and not reach
the ceiling or upper walls where detectors are located.
• Smoke particles may be blown away from detectors by air
outlets.
• Smoke detectors may be drawn into air returns before
reaching the detector.
The amount of "smoke" present may be insufficient to alarm
smoke detectors. Smoke detectors are designed to alarm at
various levels of smoke density. If such density levels are not
created by a developing fire at the location of detectors, the
detectors will not go into alarm.
Smoke detectors, even when working properly, have sensing
limitations. Detectors that have photoelectronic sensing
chambers tend to detect smoldering fires better than flaming
fires, which have little visible smoke. Detectors that have ion-
izing-type sensing chambers tend to detect fast-flaming fires
better than smoldering fires. Because fires develop in differ-
ent ways and are often unpredictable in their growth, neither
type of detector is necessarily best and a given type of detec-
tor may not provide adequate warning of a fire.
Smoke detectors cannot be expected to provide adequate
warning of fires caused by arson, children playing with
matches (especially in bedrooms), smoking in bed, and violent
explosions (caused by escaping gas, improper storage of
flammable materials, etc.).
Heat detectors do not sense particles of combustion and
alarm only when heat on their sensors increases at a prede-
termined rate or reaches a predetermined level. Rate-of-rise
heat detectors may be subject to reduced sensitivity over time.
For this reason, the rate-of-rise feature of each detector
should be tested at least once per year by a qualified fire pro-
tection specialist.
Heat detectors are designed to protect
property, not life.
IMPORTANT! Smoke detectors must be installed in the
same room as the control panel and in rooms used by the sys-
tem for the connection of alarm transmission wiring, communi-
cations, 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 people
if these devices are located on the other side of closed or
partly open doors or are located on another floor of a building.
Any warning device may fail to alert people with a disability or
those who have recently consumed drugs, alcohol or medica-
tion. Please note that:
•Strobes can, under certain circumstances, cause seizures
in people with conditions such as epilepsy.
•Studies have shown that certain people, even when they
hear a fire alarm signal, do not respond or comprehend the
meaning of the signal. It is the property owner's responsibil-
ity to conduct fire drills and other training exercise to make
people aware of fire alarm signals and instruct them on the
proper reaction to alarm signals.
•In rare instances, the sounding of a warning device can
cause temporary or permanent hearing loss.
A fire alarm system will not operate without any electrical
power. If AC power fails, the system will operate from standby
batteries only for a specified time and only if the batteries
have 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 equipment
listed for service with your control panel.
Telephone lines needed to transmit alarm signals from a
premise to a central monitoring station may be out of service
or temporarily disabled. For added protection against tele-
phone line failure, backup radio transmission systems are rec-
ommended.
The most common cause of fire alarm malfunction is inade-
quate maintenance. To keep the entire fire alarm system in
excellent working order, ongoing maintenance is required per
the manufacturer's recommendations, and UL and NFPA stan-
dards. At a minimum, the requirements of Chapter 7 of NFPA
72 shall be followed. Environments with large amounts of
dust, dirt or high air velocity require more frequent mainte-
nance. A maintenance agreement should be arranged
through the local manufacturer's representative. Maintenance
should be scheduled monthly or as required by National and/
or local fire codes and should be performed by authorized pro-
fessional fire alarm installers only. Adequate written records
of all inspections should be kept.
While a fire alarm system may lower insurance
rates, it is not a substitute for fire insurance!

WARNING - Several different sources of power can be con-
nected to the fire alarm control panel.
Disconnect all sources
of power before servicing. Control unit and associated equip-
ment may be damaged by removing and/or inserting cards,
modules, or interconnecting cables while the unit is energized.
Do not attempt to install, service, or operate this unit until this
manual is read and understood.
CAUTION -
System Reacceptance Test after Software
Changes. To ensure proper system operation, this product
must be tested in accordance with NFPA 72 Chapter 7 after
any programming operation or change in site-specific soft-
ware. Reacceptance testing is required after any change, ad-
dition or deletion of system components, or after any modifica-
tion, repair or adjustment to system hardware or wiring.
All components, circuits, system operations, or software func-
tions known to be affected by a change must be 100% tested.
In addition, to ensure that other operations are not inadvert-
ently affected, at least 10% of initiating devices that are not
directly affected by the change, up to a maximum of 50 de-
vices, must also be tested and proper system operation veri-
fied.
This system meets NFPA requirements for operation at
0-49°C/32-120°F and at a relative humidity of 85% RH (non-
condensing) at 30°C/86°F. However, the useful life of the
system's standby batteries and the electronic components
may be adversely affected by extreme temperature ranges
and humidity. Therefore, it is recommended that this system
and all peripherals be installed in an environment with a nomi-
nal room temperature of 15-27°C/60-80°F.
Verify that wire sizes are adequate for all initiating and
indicating device loops. Most devices cannot tolerate more
than a 10% I.R. drop from the specified device voltage.
Like all solid state electronic devices, this system may
operate erratically or can be damaged when subjected to light-
ning-induced transients. Although no system is completely
immune from lightning transients and interferences, proper
grounding will reduce susceptibility.
Overhead or outside
aerial wiring is not recommended, due to an increased sus-
ceptibility to nearby lightning strikes.
Consult with the Techni-
cal Services Department if any problems are anticipated or
encountered.
Disconnect AC power and batteries prior to removing or in-
serting circuit boards. Failure to do so can damage circuits.
Remove all electronic assemblies prior to any drilling, filing,
reaming, or punching of the enclosure. When possible, make
all cable entries from the sides or rear. Before making modifi-
cations, verify that they will not interfere with battery, trans-
former, and printed circuit board location.
Do not tighten screw terminals more than 9 in-lbs.
Over-tightening may damage threads, resulting in reduced
terminal contact pressure and difficulty with screw terminal
removal.
Though designed to last many years, system components
can fail at any time. This system contains static-sensitive
components. Always ground yourself with a proper wrist strap
before handling any circuits so that static charges are re-
moved from the body. Use static-suppressive packaging
to protect electronic assemblies removed from the unit.
Follow the instructions in the installation, operating, and
programming manuals. These instructions must be followed
to avoid damage to the control panel and associated
equipment. FACP operation and reliability depend upon
proper installation by authorized personnel.
Adherence to the following will aid in problem-free
installation with long-term reliability:
WARNING: This equipment generates, uses, and can
radiate radio frequency energy and if not installed and
used in accordance with the instruction manual, may

General Description
NOTI•FIRE•NET™ PN 50257:E 7/5/01 5
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. 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 Boards
The 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
Technical Manuals Online! - http://www.tech-man.com
firealarmresources.com

Service Provided
6NOTI•FIRE•NET™ PN 50257:E 7/5/01
• 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 Provided
NOTI•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
NOTI•FIRE•NET™ PN 50257:E 7/5/01 7
Overall Limitations
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 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 Circuits
The 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.

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.

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.

Configuration Definitions
14 NOTI•FIRE•NET™ PN 50257:E 7/5/01
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.
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 Configuration
A 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).

Terminating Point-To-Point and Bus Configurations
NOTI•FIRE•NET™ PN 50257:E 7/5/01 15
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. 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 Configurations
Both 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 Resistors
Terminating 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
NOTI•FIRE•NET™ PN 50257:E 7/5/01 17
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 Configuration
In 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.

•
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 Configuration
In 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.

•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-
