Section 1 – Introduction
The FireNET 4127 is an analog addressable fire alarm system that meets the
requirements of UL 864 9th Edition.
1.1 Basic Features
The basic FireNET 4127 control panel includes two SLC (Signaling Line Circuit)
loops. Each loop is capable of supporting 127 analog addressable points (can be
any combination of sensors and modules) for a total of 254 analog addressable
points on the basic panel. Two additional SLC loops can be added to the panel
increasing the analog addressable point capacity to 508. When analog sounder
bases are used, the upper addresses 128 – 254 are allocated to increase loop
capacity to 254 analog addressable points. This doubles the analog addressable
point capacity of the panel. The combination of analog addressable points
derived from sensors, modules, and sounder bases cannot exceed 800
addresses and sub-addresses maximum.
Up to 4.0 amps of power is available to drive the system, SLC loops, notification
appliances, and auxiliary equipment.
Four Class B notification appliance circuits rated at 2.5 amps each (see Section
2.7 and 2.8 for additional details regarding NAC circuit ratings).
Five programmable Form C relays are built-in to the control panel.
500 network-wide zones for device and circuit grouping.
Analog Smoke Detector Features:
Automatic Drift Compensation
Maintenance Alert
Adjustable Day/Night Sensitivity
Calibration checking meets sensitivity test requirements of NFPA 72.
Auto-Learn utility identifies system devices, which makes initial system start-up
easier.
8 line by 40 character graphic display provides the most intuitive operator
interface in the industry (320 characters total).
Help screens are available from the front panel and annunciator user interface to
assist in programming and operation.
512 additional points can be added to the system using the FN4127-IO 16
channel input/output boards. Each of these points can be programmed
individually to be an input or low current output. These points are for secondary
use only.

• Sleeping Rooms:
room.
• Hallways: More than one smoke detector should be installed in a hallway if it
is more than 30 feet long.
• At least Two Smoke Detectors: There should never be less then two smoke
detectors per apartment or residence.
• Smoke Detectors in Alarm, Electrical, or Phone Locations: Smoke detectors
should be located in any room where an alarm control is located or an alarm
control connects to an electrical source or phone line. If detectors are not so
located, a fire within the room could prevent the alarm control from reporting
a fire.
• Notification Systems: All fire alarm systems require notification devices,
including sirens, bells, horns, and/or strobes. In residential applications, each
automatic alarm initiating device when activated should cause the operation
of alarm notification device that should be clearly audible in all bedrooms
over ambient or background noise levels (at least 15dB above noise) with all
intervening doors closed.
• Alarm in Every Bedroom and Level of Residence: A smoke detector with an
integral sounder (smoke alarm) should be located in every bedroom and an
additional notification device should be located on each level of a residence.
• Maintenance: A maintenance agreement should be arranged through the
local manufacturer’s representative and maintenance should be performed
annually by authorized personnel only. To keep a fire alarm system in
excellent working order, ongoing maintenance is required per the
manufacturer’s recommendations and UL and NFPA standards. At a
minimum the requirements of Chapter 7 of NFPA 72 (1999) shall be followed.
• Test Weekly:
sensors and transmitters are working properly. The most common cause of
an alarm system not functioning when a fire occurs is inadequate
maintenance.
Alarms Cannot Guarantee Warning or Protection: Fire alarm system cannot
guarantee warning or protection against fire in every potential situation. A study by
the Federal Emergency Management Agency (an agency of the United States
government) indicated that smoke detectors may not go off or give early warning in
as many as 35% of all fires.
Smoke detectors should be installed in every sleeping
The alarm system should be tested weekly to make sure all

Limitation on Fire Alarm Effectiveness: A fire alarm system may not provide timely
or adequate warning, or simply may not function, for a variety of reasons. For
example:
• No Detection: Particles of combustion or smoke from a developing fire may
not reach the sensing chambers of smoke detectors because:
1. Barriers (such as closed or partially closed doors, walls, or chimneys)
may inhibit particle or smoke flow.
2. Smoke particles may become cold, stratify, or not reach the ceiling
or upper walls where detectors are located.
3. Smoke particles may be blown away from detectors by air outlets.
4. Smoke particles may be drawn into air returns before reaching the
detector.
• No Multi-Floor Detection: In general, smoke detectors on one level of a
structure cannot be expected to sense fires developing on another level.
• Insufficient Smoke: 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 the detector, the detector will not go into
alarm.
• Smoldering vs. Flaming Fires: Smoke detectors, even when working
properly, have sensing limitations. Detectors that have photoelectric sensing
chambers tend to detect smoldering fires better than flaming fires, which
have little visible smoke. Detectors that have ionizing-type sensing chambers
tend to detect fast flaming fires better than smoldering fires. Because fires
develop in different ways and are often unpredictable in their growth, neither
type of detector is necessarily best and a given type of detector may not
provide adequate warning of a fire.
• False Alarms and Pre-Fire Disconnection: Smoke detectors are subject to
false alarms and nuisance alarms and may have been disconnected by
users. For example, a smoke detector located in or near a kitchen may go
into nuisance alarm during normal operation of kitchen appliances. In
addition, dusty or steamy environments may cause a smoke detector to
falsely alarm. If the location of a smoke detector causes an abundance of
false alarms or nuisance alarms, do not disconnect the smoke detector, call a
professional to analyze the situation and recommend a solution.
• Fast Fires and Explosions: Smoke detectors cannot be expected to provide
adequate warning of fires caused by arson and children playing with matches
(especially within bedrooms), smoking in bed, violent explosions (caused by
escaping gas, improper storage of flammable materials, etc.).
• Heat Detectors:
Heat detectors do not sense particles of combustion and are
designed to alarm only when heat on their sensors increases at a
predetermined rate or reaches a predetermined level. Heat detectors are
designed to protect property, not life.
15
FireNET 4127 I & O Manual v1.90 UL
Page 16
• Unheeded Warning: Warning devices (including horns, sirens, and bells)
may not alert people or wake up sleepers who are located on the other side
of closed or partially open doors. A warning device that activates on a
different floor or level of a dwelling or structure is less likely to awaken or alert
people. Even persons who are aware may not notice the warning if the alarm
is muffled by noise from a stereo, radio, air conditioner or other appliance, or
by passing traffic. Audible warning devices may not alert the hearing
impaired (strobes or other devices should be provided to warn these people).
Any warning device may fail to alert people with a disability, deep sleepers,
people who have recently used alcohol or drugs, or people on medication or
sleeping pills.
• Strobes: Strobes can under certain circumstances, cause
seizures in people with conditions such as epilepsy.
• Drills: 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 responsibility to
conduct fire drills and other training exercises to make people
aware of fire alarm signals and instruct on the proper reaction to
alarm signals.
• Hearing Loss: In rare instances, the sounding of a warning
device can cause temporary or permanent hearing loss.
• Telephone Transmissions Problems: Telephone lines needed to transmit
alarm signals from a premises to a central station may be out of service or
temporarily out of service. For added protection against telephone line failure,
backup radio transmission systems are recommended.
• System Failure With Age or Lack of Maintenance: System components,
though designed to last many years, can fail at any time. As a precautionary
measure, it is recommended that smoke detectors be checked, maintained,
and replaced per manufacturer’s recommendations.
• Electrical Power Problems: System components will not work without
electrical power. If system batteries are not serviced or replaced regularly,
they may not provide battery backup when AC power fails.
• High Air Velocity or Dusty or Dirty Environments: Environments with high air
velocity or that are dusty or dirty require more frequent maintenance.
Importance of Maintenance: In general, fire alarm systems and devices will not
work without power and will not function property unless they are maintained and
tested regularly.
Alarm is Not Substitute for Insurance: While installing a fire alarm system may
make the owner eligible for a lower insurance rate, an alarm system is not a
substitute for insurance. Property owners should continue to act prudently in
protecting the premises and the people in their premises and should properly insure
life and property and buy sufficient amounts of liability insurance to meet their
needs.

2.4 Mounting the Control Panel
Consult the environmental specifications listed in Section 2.2 to determine a suitable
location to mount the FireNET 4127 main control panel.
The panel should be mounted so that it is accessible to service personnel and located
in a secure area.
Do not mount directly to a concrete wall. Use a suitable standoff material such as
plywood to keep condensation away from the control panel.
2.5 Wiring Specifications
Care should be taken when wiring the system to avoid situations that would contribute
to inducing electrical noise from one wire to another. Induced noise can interfere with
telephone communications or cause erratic system operation. Follow these guidelines
to plan your system wiring prior to installation.
• Route high and low voltage wiring separately. Maintain a minimum 2” separation
between high and low voltage wiring throughout the building.
• Route control panel wiring around the perimeter of the enclosure. A minimum
.25” separation is required between high and low voltage wiring.
• Identify which group each wire or cable is associated with from the list below.
Isolate each groups wiring as much as possible. Avoid running a single multiconductor cable for multiple groups of conductors.
• AC Power - Main Power Supply
• Notification Appliances
• SLC Circuits
• Relay Outputs
• Voltage Outputs
• Remote Control and Auxiliary Inputs
• Network Wiring (Shielded wire required)
• RS485 Bus Wiring (Shielded wire required)
• Keep wiring from different groups separated as much as possible. If you must
share the same conduit with different conductor groups consider using shielded
cable.
• If shielded cable is used terminate the shield to the earth ground terminal block
in the main control panel and leave open at field side of cable. Do not ground at
both ends of cable.
• All terminals on the FireNET control can accept wire gauges from 22AWG and
14AWG.

Section 3 - Power Supply and Main Control Unit Connections
3.1 AC Power Connection
The AC power connection terminals are located in the lower left hand corner of the
power supply module. (See Figure 3.3) Observe the wiring polarity and connect as
shown. Local electrical codes may require that a licensed electrician make these
connections.
NFPA 72 requires that the AC connection be made from a dedicated branch circuit that
is mechanically protected. The circuit must be marked in red and identified as a “FIRE
ALARM CIRCUIT”. The location of the circuit and its disconnecting means shall be
permanently noted at the fire alarm control panel. The circuit breaker must be rated at
20 amps maximum.
Fuse Replacement: To replace the power supply fuse F2, power down the fire system
by removing the AC power first, then disconnect the backup batteries to the fire alarm
control panel. Remove the blown fuse and replace with a 3A 250VAC, slow blow,
5X20mm fuse. When the fuse replacement is completed, restore AC power to the
control panel and connect the back up batteries observing polarity of connections.
3.2 Battery Connection
The FireNET 4127 fire alarm control panel can charge up to 60AH batteries. Up to 17
AH will fit in the control panel enclosure, as well as larger sizes that have the same size
footprint as 17AH batteries. Batteries larger than 17AH may be mounted remotely in the
FN-ACC accessory cabinet. Use the current draw and battery calculation worksheet in
section 2.6 to determine the appropriate size battery to use.
Two battery leads come pre-connected to the power supply module. Connect two 12volt batteries in series to the battery leads as shown in Figure 3.3. Both batteries must
be of the same AH rating. Do not try to parallel multiple batteries together to obtain a
higher AH rating. Use only UL Recognized Sealed Lead Acid Batteries.
Fuse Replacement: To replace the in-line battery fuse, remove the battery lead (RED)
from the positive battery terminal and twist the bayonet fuse holder to open. Remove
the blown fuse and replace with a “Bussman AGC-10” (10A) type fuse or equivalent.
Reassemble bayonet fuse holder and attach the battery lead to the + terminal of the
battery.
NOTE: The standby batteries cannot power the system until the main
120VAC power has been established. Once the system has
been initially powered from them 120VAC source the batteries
will operate the system in the event of a power failure.

4.2 General Installation of RS-485 Bus Devices
4.2.1 Wiring Distance and Mounting Locations
RS485 bus devices can be mounted either in the main control panel on the standoffs
provided to the right of the control unit, or in an accessory cabinet (FN-ACC). When
mounting remotely in an accessory cabinet the distance from the panel to the RS485
bus device must not exceed 4000 feet. A suitable communications cable for RS485
applications must be used for the RS485 bus devices.
Specific wiring connections for each device are included later in this section. For
specific wiring distance, connections, and mounting of the FN-LCD-S serial LCD
Annunciator, see Section 4.7.
40
FireNET 4127 I & O Manual v1.90 UL
Page 41
4.2.2 Addressing
Up to 32 RS485 bus devices can be added to the system. Each RS485 bus device
must be set to a unique address 1-32.
The address for each RS485 bus device is set using a position DIP-switch in binary
fashion. Switches 1-5 represent the values 1, 2, 4, 8, and 16, respectively. Switch 6 is
not used. To set the address, move only the switches whose values when added equal
the address value you wish to set, to the “ON” position. For example moving switches 1
and 3 (whose values are 1 and 4 respectively) to the “ON” position sets the address of
5 into the RS485 bus device. See the other examples below:
ADDRESS 1
Addresses must be set with no power applied to the system.
ADDRESS 5
ADDRESS 21
Switch Number – 1 2 3 4 5 6
Value – 1 2 4 8 16 not used
4.2.3 Terminating
The last board connected to the RS485 bus must have a
terminating jumper installed at position J3 as shown in figure
4.2.3.1
Even if only 1 RS485 bus device is connected to the panel this
jumper must be installed.

4.2.4 Power Connections
All RS485 bus devices require 24 VDC to operate. The AUX 24V terminals of the FN4127 can supply this voltage (500 milliamps maximum) or you may use an external
power supply that provides 24 VDC output.
Connections are provided on each RS485 bus device for both incoming and outgoing
power.
4.2.5 COMMS Connection
In addition to power, each RS485 bus device requires a pair of conductors for data
communication. This wiring is connected to the COMMS + and - terminals on the FN4127 control panel or can be connected to the COMMS OUT + and - terminals of
another RS485 bus device.

4.3 FN-4127-IO - Input / Output Board
In addition to the basic 508 points that the FireNET 4127 can accommodate on the SLC
loops additional input and output points can be added by using FN-4127-IO
Input/Output boards on the RS485 bus.
The FN-4127-IO has 16 channels. Each channel can be individually configured as
either an input or an output. Up to 32 FN-4127-IO boards can be connected to the
system via the RS485 bus giving the system an additional 512 inputs/outputs.
4.3.1 Configuring Inputs
Inputs to the FN-4127-IO are optically
isolated and connected to the board by
installing a normally open contact with a
resistance no greater than 500 ohms to
any input and a terminal marked 0V. The
current switched by the contact will be a
maximum of 3 milliamps.
NOTE: Inputs on the I/O board are not supervised. These inputs are not
for primary initiating or detection of fire or life safety conditions.
These inputs are for programmable for secondary use only, and
not used for signaling Fire, Supervisory, or Trouble conditions. All
primary initiating or detection inputs must be connected to
applicable SLC devices listed for fire. See Section 5 of this manual
for SLC devices.
43
FireNET 4127 I & O Manual v1.90 UL
Page 44
4.3.2 Configuring Outputs
When configured as outputs, the I/O board channels supply a negative voltage (with
respect to the I/O board 24V power supply) via a transistor.
Because transistor elements can be damaged by excessive current drain, great care
should be taken when connecting to outputs. Particular care should be taken to ensure that
suppression diodes on relay coils are correctly polarized. Wrongly connected diodes will
damage the outputs. Diodes
should be connected with the
band to the positive 24V.
Individual channels can supply
current up to 100 milliamps but
this must be limited to 500
milliamps for each bank of
eight (500 milliamps for 1-8
and 500 milliamps for 9-16).
The power supply to the I/O
board should also be
considered to ensure that its
rating is not exceeded if
multiple channels are switched
on. Overall current draw for the
I/O board is 1010mA max.
NOTE: Outputs on the I/O board are not supervised. These outputs are
not for primary notification of fire conditions (i.e. not for use as NAC
circuits). These outputs are for secondary use only. All primary
notification output devices must be connected to applicable NAC
circuits on the FireNET panel. See Section 3.4, Appendix A, and B
for details on NAC circuits and compatible NAC devices.
When powering the I/O board from the FireNET Aux 24VDC power (limited to 500ma), the
following maximum wiring distances apply at the gauges noted:
Wire
Distance
18AWG 875ft
16AWG 1400ft
14AWG 2300ft
When powering the I/O board from a separate Aux 24VDC UL Fire listed supply the
maximum voltage drop cannot exceed 4VDC.
2.2k
44
FireNET 4127 I & O Manual v1.90 UL
Page 45
4.3.3 LED Indicators
LED indicators on the I/O board give some simple diagnostic information
and show that the boards are communicating with the control panel. The
red LED (LED1) is on during receipt of a message from the control panel
and will turn off if the I/O board feels the communication is normal.
• If the LED is flickering more or less continuously - the board is
operating normally.
• If this LED is not lit - the board is not receiv ing data from the
control panel and the comms connection should be checked.
• If this LED is permanently lit - then it is likely that data is being
received but that it is being corrupted. In this case the quality of
the comms connection should be checked for interference from
mains or other noise generating sources.
The yellow LED (LED2) will flicker briefly every few seconds when the I/O
board responds to the main panel. If this LED does not flicker then it is
not responding to the control panel and the comms connection should be
checked.

4.6 FN-4127-SLC – Dual SLC Loop Expander
The FN-4127 FireNET control panel is provided with two SLC Loops, however an
additional two SLC Loops may be added at the factory or a later date if required
through the use of a FN-4127-SLC expander board.
The main control unit has terminations for connecting all four SLC loops, but on the
basic 2-loop control panels not using an SLC loop expander there is no circuitry for
SLC loops 3 & 4. The FN-4127-SLC dual loop expander board adds circuitry for loops 3
& 4.
4.6.1 Installation of the FN-4127-SLC
1. To install the additional SLC Loops, the control panel must have its 120V AC line
and battery power removed.
2. The metal cover on the terminal board should be removed by loosening the
single screw in the center of the cover.
3. The circuit board containing the additional loop circuits is supplied in a static
dissipative bag and should remain in this bag until it is to be installed.
NOTE: As with all electronic components, this circuit board is very sensitive and
can be easily damaged by electrostatic discharge.
4. The loop board mounts on the left hand side of the terminal board and fits upside
down compared with the existing circuit. The additional 2-loop circuit board is
supplied with 2 ribbon cables of different sizes and the board should be oriented
so that the ribbon cables match the connectors.
5. Install the four mounting standoffs to the main board, then attach the additional
2-loop board using the M3 screws and fiber washers.
6. After checking that the new circuit board is properly installed and making good
contact with its connectors, the metal cover should be replaced. Connect the
SLC loop wiring, then re-apply power to the control panel.
7. Unused detection circuits must have the "loop + out" to "loop + in" and "loop out" to "loop - in" terminals wired together to prevent open circuit troubles from
being reported. Class B SLC circuits also require the 0 ohm jumpers to be
installed – please see Section 5.3.1.
Once the detection circuits have been connected, the devices for the new detection
circuits can be automatically detected using the auto learn feature from the menu on
the control panel (see Section 8 of this manual).

5.2 Number of Devices
The FireNET 4127 comes with 2 SLC loops built-in to the panel. Each loop can support
up to 127 analog addressable detectors and modules as well as 127 analog sounder
bases for a total of 254 possible per loop. By adding the FN-4127-SLC expander card,
2 additional SLC loops can be added to the panel for a total of 4 loops.
Addresses 1 – 127 are reserved for any combination of detectors and modules.
Addresses 128 – 254 are reserved for analog sounder bases. Detectors and modules
cannot be addressed to the upper address 128 - 254. Each device on the SLC loop
must have a unique address. Refer to section 5.4 for instructions on programming the
address into each analog addressable device.
5.3 SLC Loop Wiring
The FireNET 4127 uses the patented Hochiki DCP Digital Communication Protocol to
communicate with each of the analog addressable devices located on the SLC loops.
This extremely fast and reliable protocol allows the use of standard non-twisted, nonshielded wiring for the SLC loops.
The SLC loop wiring may be any solid or stranded cabling that meets the requirements
for power limited fire protective signaling circuits listed in NFPA 70 (National Electrical
Code) Article 760. The wiring resistance on the SLC loop must be less than 50 ohms.
Loop capacitance must be less than 1

Additional Notes Regarding Class A Style 6 and Style 7 SLC loops:
• No t-taps are allowed on Class A SLC loops.
• The return side of the loop must be routed separately from the outgoing loop.
• The return side may not share the same conduit or cable as the outgoing side of
the SLC loop.
• When using Class A Style 7 wiring, the SCI Short Circuit Isolator must be
installed before and after each analog addressable device on the SLC loop. The
wiring from the control panel to the first SCI and from the last SCI back to the control
panel must be in conduit. Refer to Section 5.14 for more information on installing
the SCI module and for installation method to satisfy Style 7 criteria per NFPA 72.
• Refer to NFPA 72 for additional requirements of Class A circuits.
5.4 Addressing Devices
Prior to installation, all of the addressable devices installed on each of the FireNET
4127 SLC loops must be programmed with a unique address ranging from 1 to 127.
The analog sounder bases will automatically derive their address from the host sensor
(detector) attached to them. The ASB address will be the sensor address + 127 (i.e. N
+ 127). Example: The sensor address is 36. 36 +127 = 163. The ASB will have an
address of 163. This address is what the FireNET 4127 control panel uses to identify
each addressable device and control its functionality. All Hochiki addressable devices
come from the factory preset to address 127. This preset address can be
reprogrammed using the Hochiki TCH-B100-NS programmer. Follow these instructions
to set/reprogram the address.
1. Identify each analog addressable device that will be installed on an SLC loop
and label it with a unique address ranging from 1 to 127.
2. Using the Hochiki TCH-B100-NS programmer as shown in Figure 5.4, program
the appropriate address into each analog addressable device.
55
FireNET 4127 I & O Manual v1.90 UL
Page 56
Figure 5.4 Hochiki TCH-B100-NS Programmer Connections
1. ASB Automatically derives its address from host sensor (N + 127).
2. Devices must not be powered when using the TCH-B100-NS programmer to set
addresses.
3. Mini-modules such as the FRCME-S and FRCME-P should not be connected to
the SLC loop when using the TCH-B100-NS programmer to set addresses.
4. When programming the AMS, use the same method as the 4-S type
addressable modules.

The supervised voltage output of the SOM-R is rated at 2.0A maximum.
The alarm time for the SOM-R battery calculation shall be 5 minutes in the “active
status”.
NOTE: These installation instructions must be followed completely in order to comply
with agency requirements! Failure to follow these installation instructions may result in
improper operation of the SOM-R.
1. Determine the mounting location for the SOM-R, FRCME and SOM-R-DS keyswitch.
These should be installed in the same location, or as required by your AHJ.
2. The SOM-R must be addressed using the TCH-B100 programmer. Connect the
SOM-R to the FN-4127 SLC as shown in Figure 5.15.1. Refer to the installation
instructions (Part # 1700-11320, Rev. 05/10) included with the SOM-R for additional
wiring and installation instructions.
3. Connect 24VDC power to the SOM-R module. This voltage may be provided by; 1)
a UL 1481 listed, regulated, power limited supply, 2) a FN-4127 NAC circuit configured
as continuous auxiliary power, or 3) the FN-4127 aux power on X2 terminals 18 and 19
(500ma max).
4. The SOM-R-DS keyswitch connected to the FRCME module must be connected to
the FireNET SLC. Use the TCH-B100 programmer to assign an address to the module
and then connect the SLC circuit to the S+ and SC- terminals on the module.

Operation of the SOM-R
-
+
-
The SOM-R is designed for use with single interlock preaction sprinkler systems. When
the FireNET control panel detects a fire alarm condition from a single initiating point,
the SOM-R will be activated, allowing water to flow into the sprinkler piping. Water is
not discharged from a sprinkler head until increased temperature from the fire activates
the sprinkler head.
Output delays are not applied to the activation of the SOM-R. The SOM-R output is
activated immediately upon detection of a fire condition by the FireNET control panel.
73

Important! For proper operation, program the SOM-R Output Attributes as follows:
o Gen Alarm Mode = YES
o Silenceable = NO
o Emergency = NO
o Pre Alarm = NO
o Trouble = NO
o Pattern = CONTINUOUS
o Edit Location Text = SOMR
Program the FRCME attributes as follows:
o Set Input Type = GEN PURPOSE N/C EOL
o Set Input Action = SUPERVISORY
Set Input Latch = NO
o
o
Set Input Delay = 0s
o Edit Location Text = SOMR IS DISABLED
Other settings may be assigned as needed.
Failure to follow these programming instructions may result in incorrect
operation of the SOM-R module!
NOTE: The location text will need to be programmed to state “SOMR PREACTION
DISCHARGE” for all initiating devices, which activates the SOM-R module.
Alarm Verification may not be used with the SOM-R.

Maintenance:
A maintenance agreement should be arranged through the local
manufacturer’s representative and maintenance should be performed annually by
authorized personnel only. To keep a preaction system in excellent working order,
ongoing maintenance is required per the manufacturer’s recommendations and UL and
NFPA standards. At a minimum the requirements of Chapter 13 of NFPA 25 (2010)
shall be followed.
Test Weekly:
The preaction system should be tested weekly to make sure SOM-R,
FRCME and SOM-R-DS (Bypass Keyswitch) are working properly. The most common
cause of an alarm system not functioning when a fire occurs is inadequate
maintenance.

5.15 CZM Conventional Zone Module
The Conventional Zone Module (CZM) connects to the Signal Line Circuit (SLC). The
module allows the analog panel to interface and monitor conventional devices such as
pull stations and two-wire smoke detectors. The CZM is typically used in retrofit
situations where pre-existing conventional zones are removed from a conventional
system and then connected to the analog panel for discrete monitoring of that zone. All
conventional devices connected to a single CZM are reported as a single input. Status
conditions are reported as normal, open or alarm. It supervises the external power
supply as well as the entire zone of devices. Refer to the installation instructions
included with the CZM for more detailed wiring and installation instructions.

5.16 DIMM Dual Input Monitor Module
The Hochiki DIMM Dual Input Monitor Modules were designed to work with pull
stations, water flow switches, and other applications requiring the monitoring of dry
contact alarm initiating devices. The DIMM can monitor two independent inputs with
discrete reporting, yet the module only requires a single address on the SLC Loop. A
typical example would be for use with a waterflow and tamper application. One input
would be connected to the waterflow switch for a fire alarm condition. The second input
would be connected to the tamper switch for a supervisory condition. A single DIMM
module would be used instead of two single input modules such as the FRCME. The
DIMM inputs operate in a similar fashion to the FRCME input. Refer to the installation
instructions included with the DIMM for more detailed wiring and installation
instructions.

5.17 SCI Short Circuit Isolator Module
The SCI short circuit isolator module is designed to help maintain partial SLC loop
operation in the event that the SLC loop becomes shorted, positive to negative. In the
event of an SLC loop short circuit the SLC loop is typically inoperative. By installing SCI
modules throughout the SLC loop only a portion of the loop will be inoperative in the
case of an SLC short circuit. When SCI modules are installed adjacent to every device
for true Style 7 (see Section 5.17.1), no devices are lost from a single short on the SLC
loop.
Connect the SCI module to the FireNET 4127 control panel as shown in Figure 5.17.1.
Refer to the installation instructions included with each SCI for more detailed wiring and
installation instructions.

5.17.1 Class A Operation
The SCI should be located within 5 feet of the FN-4127 control panel on both the
outgoing and incoming SLC loop legs. In addition an SCI should be located between
every SLC loop detector and module as shown in figure 5.17.2 and is required for
NFPA 72 Class A Style 7 compliance. For Class A Style 6 compliance the SCI modules
may be located at strategic locations based on the installer’s or system designer’s
discretion.
In the event of a short circuit on the SLC loop the 2 adjacent SCI modules to the short
(closest SCI on the left and the right of the short) will activate and its LED will turn on.
All the devices between the two SCI modules will be isolated and inoperative. All other
devices on that SLC loop will remain operational. The FN-4127 control panel will
indicate a trouble condition. When installing SCI modules for true Style 7 compliance,
the SCI modules must be installed in a “closed nipple” fashion (see Figure 5.17.2). By
using this method, no devices are lost from a single short on the SLC Loop.

• FN-4127-NIC
Network Devices
• FN-LCD-N Network LCD Annunciator
This section covers the installation of the devices listed above. For proper operation
each of these devices must be programmed using the Loop Explorer software. Please
refer to Section 9 of this manual for more information on programming the functionality
of network devices.
The FireNET system enables information to be transmitted between control panels
using a secure network connection. Up to sixty-four control panels and network
annunciators (nodes) can be connected together and the system can be configured
such that selected information can be displayed or acted upon at each panel.

6.1.1 FN-4127-NIC Network Interface Card
To enable control panels to be connected together
as a network, a network card must be installed in
each panel. This card connects to the FN-4127 on
the rear of the panel door and is held in position by
two M3 screws. The network card is installed in the
exact same fashion for the FN-LCD-N Network LCD
annunciator.
To install a network card, the AC and battery power
must first be switched off and the metal cover over
the front panel PCB removed. The network card can
then be plugged into the two connectors (J1 and J3)
in the bottom right of the main panel PCB and
secured in position with the M3 screws.

Each network node must
be allocated a unique
network address. This is

6.1.1.1 Cable Length
The FireNET network communications protocol has been designed to be extremely
tolerant to interference and data corruption, however as with any system, limitations
must be set to guarantee correct operation. The specified transmission distance limit for
the communications method used is 4000 ft. (1200m) and because the data is retransmitted at each network card, in theory, there can be 4000 ft. (1200m) between
each card if required. The minimum cable size for the FireNET network is #20 AWG.
The network communications uses RS485 technology.
Using the above cable distances however, does not take into account the failure of a
network card to communicate with the system through total power failure or a card
trouble. In this situation, the network card would disconnect itself from the network and
connect the network cable such that it bypasses the card in question. This means that
the total cable length between the cards either side of the disconnected one could be
8000 ft. (2400m), which is outside of the specification for the communications method
used (RS485). This trouble scenario could clearly be extended to more network cards
and this would add 4000 ft. (1200m) of cable length in each case.
A sensible trouble tolerance limit must therefore be suggested to enable the
performance of the system to be predicted. Because of the nature of the fire protection
system, its design is biased towards inherent reliability and failure of a network card,
although possible, is very unlikely. Fire control panels also have substantial back up
power systems, therefore, the likelihood of a total power failure under operational
conditions, is also extremely rare. A suggested tolerance level of one card failure is
therefore recommended. To guarantee operation of the system with one card failure it
is necessary to arrange the network so that a failure will not introduce more than 4000
ft. (1200m) of cable between the two cards, which would be connected together by the
failure. This means that the total cable length between adjacent nodes should not be
more than 4000 ft. (1200m). It is not important how the 4000 ft. (1200 meters) is made
up i.e. it could be 350 ft. (100m) and 3650 ft. (1100m) or 2000ft. (600m) and 2000ft.
(600m).
Using these general rules and the specified or equivalent cable types will provide a
guaranteed performance of networks with plenty of tolerance.

Annunciator
When designing or installing a network of FireNET panels and annunciators, always be
aware of the following:
1. The panel network must be wired as a ring (Class A).
2. There should be no more than 4000 ft. (1200m) maximum cable length between
two adjacent segments.
3. A short circuit at
Point A should automatically disconnect the shorted section
and announce a trouble condition at all panels but the entire network will
continue communicating.
4. A short circuit at
Points A and B should automatically disconnect both sections
and announce trouble at all panels. Communication will continue between
panels1 and 4 and between panels 2 and 3.
5. Open circuit troubles should allow the network to continue operating in the same
way as short circuit troubles.
6. Network cabling should be standard RS485 type for up to 64 nodes.
7. The minimum cable size for the FireNET network is #20 AWG.
86
FireNET 4127 I & O Manual v1.90 UL
Page 87
6.1.1.3 Cable Type
The cable type used for the network connection should be suitable for RS-485
applications. Minimum wire size should be 20ga. twisted, shielded, stranded. RS485
communications cable is typically standard Class 2 communications cable. However,
depending on the AHJ, FPL or FPLR cable may be required. Follow local jurisdictional
and AHJ requirements. NFPA 70 national electric code compliance may be required for
network cabling depending on local jurisdiction, AHJ, regulations, and/or codes.
6.1.1.4 Proper Shield Termination of the Network Cable
In many installations, interference from RFI, EMI or other noise sources can create
problems. In order to reduce the effects of such noise, terminate the shield to the earth
ground terminal block in the main control panel. DO NOT ground the shield at both
ends of the cable!

6.1.2 FN-LCD-N Network Liquid Crystal Display Annunciator
The FN-LCD-N Network Annunciator duplicates the indications of the FN-4127 fire
alarm control panels connected to the same network. The FN-LCD-N connects to the
control panel via the network interface and requires that the main control panel have an
FN-4127-NIC network card fitted.
The FN-LCD-N Network Annunciator is connected to the network and any number of
panels can be connected up to the maximum number of nodes allowed by the network
specification, which is 64 (including control panels).
Specific network attributes and routing information from any or all control panels may
be assigned to the FN-LCD-N. The LCD display and user interface on the FN-LCD-N
operate and indicate in the same manner as the control panel.
The FN-LCD-N is considered a network “node” to the FireNET network just like the
control panels.
For operations and programming refer to Sections 7, 8 and 9 of this manual.

7.1 Operating Modes
This section provides a brief overview of Access Level 1, 2, and 3 operating modes.
Access Level 1 and 2 operating modes are used in the basic system operations
described in this chapter. Access Level 3 is typically used only by installation and
service personnel and is explained in greater detail in Section 8 of this manual.
7.1.1 Access Level 1
When the FN-4127 control panel is in
Power On LED will be lit, and the date and time displayed on the LCD display. Normal
Standby is considered to be in Access Level 1. Some very basic operations can be
done in Access Level 1 by simply pushing the corresponding button(s) on the front
panel controls. For information on which basic user operations can be done from
Access Level 1 see section 7.2.
Note that when using the Denver Door build the control panel buttons are not
accessible until the door is opened.
7.1.2 Access Level 2
Many of the front panel controls and their operations require the user to enter a more
secure operating mode called Access Level 2. This more secure operating mode
prevents unauthorized individuals from operating the FN-4127 fire alarm system. For

Each menu option may be selected by first highlighting it using the up/down arrow keys,
then pressing the right arrow key to select. The six Access Level 2 Main Menu option
functions are described in the following sections.
7.4.2 Disablements
The Disablements menu allows the user to disable individual points, circuits, zones, or
loops on the FN-4127 fire alarm system. This is typically done while the system is being
serviced or tested or to temporarily remove a faulty system device. CAUTION: Any
portion of the system that is disabled will not report an alarm condition.
All disablements have two options, timed or untimed. For disablements up to 24 hours
in length the timed disablement option should be used. This will prompt the user to
enter a disablement time in 30-minute increments from 30 minutes to 24 hours. Once
the disablement begins the FN-4127 will countdown the selected disablement time.
When the time expires the disablement is cancelled automatically.
Untimed disablements should be used only when it is necessary to disable a portion of
the system for over 24 hours. Untimed disablements remain active until they are
manually reset at the panel through the Access Level 2 Main Menu / Disablements
command.

FireNET 4127 I & O Manual v1.90 UL
Page 97
Once you select timed or untimed disablement you can choose to disable loops, zones,
addresses, NAC, or I/O circuits through sub-menus to the Access Level 2 Main Menu /
Disablements option.
As previously discussed highlighting the desired menu option and then pressing the
right navigational arrow selects that option. Pressing the left navigational arrow at any
time backs out of the current menu returning to the previous menu.
Note: The FN-4127 fire alarm system will indicate a disabled condition any time there is
an active disablement on the system, via LCD display text and the “point bypassed”
LED on the front panel. Any item disabled is considered an off-normal condition and will
generate a common trouble condition until the disabled item is returned to normal.
7.4.2.1 Disabling Loops
The Disable Loops sub-menu option to Disablements, allows you to disable an entire
SLC loop with one command. The SLC loop may contain up to 127 analog detectors
and addressable input and/or output modules, as well as up to 127 analog sounder
bases. Disabling an entire SLC loop disables all inputs and outputs on the loop and
should be used only in extreme cases such as a service related problem affecting all
the devices on the SLC loop.
WARNING: Loop disablement does not electrically isolate the panel from the SLC loop
wiring. The SLC loop should be disconnected from the panel before any diagnostic
testing is performed.
Disabling Zones
Each device on the system is assigned to a zone by the system installer. Refer to the
installation records in Section 11 of this manual for a list of all points on the system and
the zones they are assigned to. A zone may consist of one or many points. Disabling a
zone disables all the points assigned to that zone.
Disabling Addresses
Each SLC loop device on the system is assigned a unique address. In some cases an
SLC loop device may have sub addresses as well. Using the Disable Address submenu command the user can individually disable any single address on the system.
97
FireNET 4127 I & O Manual v1.90 UL
Page 98
Disabling NAC Outputs
The disable Audible Device output sub-menu option allows the user to disable all of the
local NAC, SOM, and ASB outputs on the system. This is typically done for periodic
tests so the building occupants are not disturbed while activating each alarm device.
When you choose this option all of the notification appliances connected to the panel
notification appliance circuits and SOM are disabled, as well as any analog sounder
bases.
Disable Panel I/O
The Disable Panel I/O sub-menu option allows a user to disable an individual panel
input or output. This includes individual notification appliance (NAC) circuits, on-board
panel relays, and the on-board digital inputs. This option applies only to on-board
inputs and outputs – SLC loop devices must be disabled by using the Disable
Addresses option.
View / Restore Disablements
The View/Restore Disablements sub-menu option is used to quickly display any system
disablements and optionally reset them to normal. Scroll to the View/Restore
Disablements sub-menu option, press the right navigational arrow to select, and then
follow the prompts on the panel display to view/reset any disablements on the system.
7.4.3 View Devices
The View Devices menu option allows the user to view every SLC loop device. For
each device the panel display will indicate the device type, zone, and location text. In
addition, analog devices such as smoke and heat detectors will also be displayed with
their current analog value. This analog value can be useful in determining if a smoke
detector requires cleaning. Photoelectric detectors also display in terms of obscuration
(%/ft) and the heat detectors in terms of temperature (F°).
For non-analog input devices the current status will be displayed as Off or On. For nonanalog output devices the current status will be displayed as either Off or Activated.
Service personnel who want to verify system devices and troubleshoot potential
problems typically use the View Devices sub-menu option.
7.4.4 Test Zones
The Test Zones sub-menu option is used by service personnel to quickly and easily
perform periodic system tests. Please refer to Section 10 of this manual for a more
detailed explanation. This feature is typically referred to as a “One Man Walk Test.”
