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 notification capability—can provide early warn ing 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 met hods—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
Protection Association S tandard 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 Management Agency (an agency of the United
States governme nt) 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. 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 building.
A second-floor detector, for example, may not sense a first-floor
or basement fire.
Particles of combustion or “smok e ” from a developing fire
may not reach the sensing chambers of smoke detectors
because:
• Barriers such as closed or partially closed doors, walls, chimneys, 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 aw a y from de tectors by air
outlets, such as air conditioning vent s.
• 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 designe d to ala rm 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 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 growt h, neither type of detector i s
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 al arm
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 shoul d 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,
signaling, 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,
speakers 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 people 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 desi gned to meet intelligibility requirements as defined by NFPA, local codes, and
Authorities Having Jurisdiction (AHJ).
• Language and instructional requirements must be clearly disseminated on any local displays.
• Strobes can, under c ertain circumstances, cause seizures in
people with conditions such as epilepsy.
• Studies have sh own that certain people, even when they he ar
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
l
is
ted 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
inadequate maintenance. To keep t he entire life safety sys tem in
excellent working order , ongoing mai ntenance is required per the
manufacturer's recommendations, and UL and NFPA standards. At a minimum, the requirements of NFPA 72 shall be followed. Environments with large amounts of dus t, dirt, or hig h air
velocity require more frequent maintenance. A maintenance
agreement should be arranged through the local manufacturer's
representative. Maintenance should be scheduled monthl y or as
required by National and/or local fire codes and should be performed by authorized professional life safety system installers
only . Adequate written reco rds of all inspecti ons should be kept.

Installation Precautions
Adherence to the following will aid in problem-free installation with long-term reliability:
WARNING - Several different sources of power can be
connected to the fire alarm control panel. Disconnect all
sources of power before servicing. Control unit and associated equipment 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 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 operation or change in site-specific software. Reacceptance testing is required after any change, addition or
deletion of system components, or after any modification,
repair or adjustment to system hardware or wiring. All components, circuits, system operations, or sof tware functions known
to be affected by a change must be 100% tested. In addition,
to ensure that other operations are not inadvertently 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 NFPA requirements for operation at 0-49º
C/32-120º F and at a relative humidity 93% ± 2% RH (noncondensing) at 32°C ± 2°C (90°F ± 3°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 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 initia ting and indicating device loops. Most devices cannot tol erate 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 subject ed to li ght ning induced transients. Although no system is completely
immune from lightning transients and interf erence, proper
grounding will reduce susceptibility. Overhead or outside aerial
wiring is not recommended, due to an increased susceptibility
to nearby lightning strikes. Consult 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. Overtightening may damage threads, resulting in reduced terminal
contact pressure and difficulty wit h screw terminal removal.
This system contains static-sensitive components.
Always ground yourself with a proper wrist strap before handling any circuits 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 inst al lati on, ope rati ng, and programming manuals. These instructions must be followed to
avoid damage to the control panel and a ssociated equipment.
FACP operation and rel iability depend upon proper inst allat ion.

Section 1: Product Description
The MS-9050UD is a combination FACP (Fire Alarm Control Panel) and DACT (Digital Alarm
Communicator/Transmitter) all on one circuit board. This compact, cost effective, intelligent
addressable control panel has an extensive list of powerful features. The combination of Fire-Lite’s
newer series devices and legacy 300 Series devices, along with the MS-9050UD FACP, offer the
latest in fire protection technology. The power supply and all electronics are contained on a single
circuit board housed in a metal cabinet, providing a complete fire control system for most applications. Availa ble accessories include local and remote upload/download software, remote annunciators and reverse polarity/city box transmitter.
The integral DACT transmits system status (alarms, troubles, AC loss, etc.) to a Central Station via
the public switched telephone network. It also allows remote programming or interrogation of the
control panel using the PS-Tools Upload/Download utility via the public switched telephone network. Any personal computer with Windows
of 2400 baud or faster and Upload/Download software kit PK-CD, containing PS-Tools, may serve
as a Service T erminal. This allows download of the entire program or upload of the entire program,
history file, walktest data and current status.
The MS-9050UDC is a ULC-approved Canadian version of the FACP which offers the same features as the MS-9050UD, but is supplied standard with a dress panel and one built-in ANN-LED
annunciator. Refer to“Canadian Option” on page 91 for a full descriptio n.
The MS-9050UDE offers the same features as the MS-9050UD but allows connection to 220/240

2.5 Notification Appliance Circuits
The control panel provides two NACs (Notification Appliance Circuits) Style Y (Class B) or Style
Z (Class A). Each circuit is capable of 2.5 amps of current. Total current in alarm for all external
devices cannot exceed 2.5 amps (refer to “Calculating the System Current Draw” on page 154).
Use UL listed 24 VDC notification appliances only. Circuits are supervised and power-limited.
Refer to the Fire-Lite Device Compatibility Document for a listing of compatible notification appliances. The NACs, which are located on the main circuit board, may be expanded via the Fire-Lite
FCPS Series field charger/power supplies.
NACs can also be configured for auxiliary power. If set for auxiliary power (door holder, resettable
power, non-resettable power) do not connect notification appliances. Refer to Section 1.2, “Specifications” for power capability.
The following sections describe the configuration and wiring of Style Y and Style Z Notification
Appliance Circuits on the FACP main circuit board.
2.5.1 Configuring NACs
The Notification Appliance Circuits are configured for Style Y (Class B) or Style Z (Class A) by
properly wiring the NAC devices to TB1 on the main circuit board as illustrated below.
