Fire Alarm & Emergency Communication System Limitations
While a life safety system may lower insurance rates, it is not a substitute for life and property insurance!
An automatic fire alarm system—typically made up of smoke
detectors, heat detectors, manual pull stations, audible warning
devices, and a fire alarm control panel (FACP) with remote notifica-
tion 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.
An emergency communication system—typically made up of an
automatic fire alarm system (as described above) and a life safety
communication system that may include an autonomous control
unit (ACU), local operating console (LOC), voice communication,
and other various interoperable communication methods—can
broadcast a mass notification message. Such a system, however,
does not assure protection against property damage or loss of life
resulting from a fire or life safety event.
The Manufacturer recommends that smoke and/or heat detectors
be located throughout a protected premises following the
recommendations of the current edition of the National Fire
ProtectionAssociation 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. This document can be found at http://
www.systemsensor.com/appguides/. A study by the Federal
Emergency ManagementAgency (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 designed to
provide early warning against fire, they do not guarantee warning or
protection against fire.Afire 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 building.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 because:
• Barriers such as closed or partially closed doors, walls, chim-
neys, even wet or humid areas 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 out-
lets, such as air conditioning vents.
• Smoke particles 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 devel-
oping fire at the location of detectors, the detectors will not go into
alarm.
Smoke detectors, even when working properly, have sensing limita-
tions. Detectors that have photoelectronic 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.
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 predetermined 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 protection 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 system for the
connection of alarm transmission wiring, communications, signal-
ing, and/or power. If detectors are not so located, a developing fire
may damage the alarm system, compromising its ability to report a
fire.
Audible warning devices such as bells, horns, strobes, speak-
ers and displays 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 peo-
ple with a disability or those who have recently consumed drugs,
alcohol, or medication. Please note that:
• An emergency communication system may take priority over a
fire alarm system in the event of a life safety emergency.
• Voice messaging systems must be designed to meet intelligibility
requirements as defined by NFPA, local codes, andAuthorities
Having Jurisdiction (AHJ).
• Language and instructional requirements must be clearly dis-
seminated on any local displays.
• 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 to or comprehend the meaning
of the signal.Audible devices, such as horns and bells, can have
different tonal patterns and frequencies. 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 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 life safety 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 compatible
with the control panel. It is essential to use only equipment listed for
service with your control panel.
Telephone lines needed to transmit alarm signals from a premises
to a central monitoring station may be out of service or temporarily
disabled. For added protection against telephone line failure,
backup radio transmission systems are recommended.
The most common cause of life safety system malfunction is inad-
equate maintenance. To keep the entire life safety system in excel-
lent working order, ongoing maintenance is required per the
manufacturer's recommendations, and UL and NFPAstandards. At
a minimum, the requirements of NFPA72 shall be followed. Envi-
ronments with large amounts of dust, dirt, or high air velocity require
more frequent maintenance.A maintenance agreement should be
arranged through the local manufacturer's representative. Mainte-
nance should be scheduled as required by National and/or local fire
codes and should be performed by authorized professional life
safety system installers only.Adequate written records of all inspec-
tions should be kept. Limit-D2-2016

Installation Precautions
Adherence to the following will aid in problem-free installation with long-term reliability:
WARNING - Several different sources of power can be con-
nected to the fire alarm control panel. Disconnect all sources of
power before servicing. Controlunit and associated equipment may
be damaged by removing and/or inserting cards, modules, or inter-
connecting cables while the unit is energized. Do not attempt to
install, service, or operate this unit until manuals are read and
understood.
CAUTION - System Re-acceptance Test after Software
Changes: To ensure proper system operation, this product must be
tested in accordance with NFPA 72 after any programming opera-
tion or change in site-specific software. Re-acceptance testing is
required after any change, addition or deletion of system compo-
nents, or after any modification, repair or adjustment to system
hardware or wiring.All components, circuits, system operations, or
software functions known to be affected by a change must be 100%
tested. In addition, to ensure that other operations are not inadver-
tently affected, at least 10% of initiating devices that are not directly
affected by the change, up to a maximum of 50 devices, must also
be tested and proper system operation verified.
This system meets NFPArequirements for operation at 0-49º C/
32-120º F and at a relative humidity 93% ± 2% RH (noncondens-
ing) at 32°C ± 2°C (90°F ± 3°F). However, the useful life of the sys-
tem'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 its peripherals
be installed in an environment with a normal room temperature of
15-27º C/60-80º 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 lightning induced
transients. Although no system is completely immune from light-
ning transients and interference, proper grounding will reduce sus-
ceptibility. Overhead or outside aerial wiring is not recommended,
due to an increased susceptibility to nearby lightning strikes. Con-
sult with the Technical Services Department if any problems are
anticipated or encountered.
Disconnect AC power and batteries prior to removing or inserting
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 modifications,
verify that they will not interfere with battery, transformer, or printed
circuit board location.
Do not tighten screw terminals more than 9 in-lbs. Over-tighten-
ing may damage threads, resulting in reduced terminal contact
pressure and difficulty with screw terminal removal.
This system contains static-sensitive components. Always
ground yourself with a proper wrist strap before handling any cir-
cuits so that static charges are removed from the body. Use static
suppressive packaging to protect electronic assemblies removed
from the unit.
Follow the instructions in the installation, operating, and pro-
gramming manuals. These instructions must be followed to avoid
damage to the control panel and associated equipment. FACP
operation and reliability depend upon proper installation.

Section 1: Product Description
The Notifier FirstCommand NFC-50/100 is a single channel, 50 watt, 25 VRMS, emergency voice evacuation panel that may be used for
fire applications, mass notification applications, or both. The NFC-50/100 comes standard with one speaker circuit. The panel provides
the ability to record fourteen field programmable messages (up to 60 seconds each) with an integral microphone or from an external
audio source. An integral power supply with battery charger supplies operational power. A 50 watt audio amplifier is built into each
panel. An optional second 50 watt amplifier (NFC-BDA-25/70V) is also available for backup purposes or to provide an additional 50
watts. The backup amplifier is available in either 25 volts or 70 volts depending on which application is necessary.
Automatic activation of the NFC-50/100 by an FACP is possible via eight Command Input Circuits (CMD) or via the ACS/ANN Bus
serial communications link from the FireWarden-100X, FireWarden-100-2, NFS2-640, and NFS-320 FACPs.
Two Command Input Circuits can be independently field programmed for activation by an FACP NotificationAppliance Circuit reverse
polarity or by closure of a supervised normally open contact and six Command Input Circuits activate on contact closure. CMD 1 and
CMD 2 provide terminals for NAC input and output to allow installation of the audio panel anywhere along the NAC circuit being used
to activate it.
If the message generator fails, the system automatically reverts to a backup tone generator.
Power is fed independently to each amplifier so that a short circuit in one amplifier will not shut down the other. Full output power of 50
watts per amplifier is generated while in a low battery condition. Power is not diminished when the optional 70 VRMS transformer mod-
ule is installed.Audio is amplified utilizing modern integrated circuits as opposed to transformer technology. This provides for very low
signal distortion for crystal clear audio.
Primary applications for the audio panels include protecting structures such as military facilities, restaurants, schools, auditoriums,
places of worship, buildings with occupancies over 50, etc. The NFC-50/100 is designed to interface directly to addressable or conven-
tional (CMD inputs 1-8) fire alarm control panels or can be used with the NFC-50/125DApanel to distribute audio in systems that
require more than 100 watts.
For Canadian applications, refer to Appendix C on page 83.
