Fire Alarm System Limitations
While a fire alarm system may lower insurance
rates, it is not a substitute for fire 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 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 detectors 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 Emergency 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 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 "smoke" from a developing fire
may not reach the sensing chambers of smoke detectors because:
• 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 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 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 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, signaling, and/or power. If detectors are not so
located, a developing fire may damage the alarm system,
crippling 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 medication. 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 responsibility 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 compatible 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 telephone line failure, backup radio transmission systems are recommended.
The most common cause of fire alarm malfunction is inadequate 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 standards. At a minimum, the requirements of NFPA 72 shall be
followed. Environments 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. Maintenance should be
scheduled monthly or as required by National and/or local
fire codes and should be performed by authorized professional fire alarm installers only. Adequate written records of
all inspections 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 con-
nected 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 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 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 software 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 indoor dry operation at 0-49° C/32-120° F
RH (non-condensing) at 32 ±2° C/90 ±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 all peripherals be installed in
an environment with a nominal 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.
and at a relative humidity of 93 ±2%
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 lightning transients and interferences,
proper grounding will reduce susceptibility. Overhead or out-
side 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, 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 removed 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.

Product Description Product Features
SECTION 1 Product Description
The MS-2 is a two zone FACP (Fire Alarm Control Panel) and the MS-4 is a four zone
FACP. The information in this manual refers to both the MS-2 and MS-4 unless
otherwise specified. These control panels provide reliable fire signaling protection for
small to medium sized commercial, industrial and institutional buildings. The FACP is
compatible with System Sensor’s I
conventional smoke detectors that can transmit a maintenance trouble signal to the
FACP indicating the need for cleaning and a supervisory ‘freeze’ signal when the
ambient temperature falls below the detector rating (refer to System Sensor’s I
Installation and Maintenance Instructions document I56-1800-00 for device
specifications). In addition, the control panel is compatible with conventional input
devices such as two-wire smoke detectors, four-wire smoke detectors, pull stations,
waterflow devices, tamper switches and other normally-open contact devices. Refer to
Fire•Lite Device Compatibility Document for a complete listing of compatible devices.
Outputs include one NAC (Notification Appliance Circuit) on the MS-2 and two NACs
on the MS-4. Each FACP has a Form-C Alarm and Trouble relay and 24 VDC special
application resettable power. In addition, the MS-4 has a Form-C Supervisory relay
and a nonresettable special application power output. The FACP supervises wiring, AC
voltage and battery level.
3
detectors which are microprocessor-based

Activation of a compatible smoke detector or any normally-open fire alarm initiating
device will activate audible and visual signaling devices, illuminate an indicating LED,
sound the piezo sounder at the FACP, activate the FACP alarm relay and operate an
optional module used to notify a remote station or initiate a auxiliary control function.
The MS-2E and MS-4E offer the same features as the MS-2 and MS-4 but allows
connection to 220/240 VAC.
Note: Unless otherwise specified, the terms MS-2 and MS-4 are used in this manual to
refer to the MS-2 and MS-2E as well as the MS-4 and MS-4E FACPs respectively.

Backbox Mounting Installation
SECTION 2 Installation
The cabinet can be surface mounted or semi-flush mounted using the optional Trim
Ring P/N: TR-1-R. The door is removable during the installation period by opening
and lifting if off the hinges. The cabinet mounts using two key slots at the top of the
backbox and two additional 0.250” diameter holes located at the bottom.
Carefully unpack the system and check for shipping damage. Select a location for the
cabinet that is in a clean, dry, vibration-free area where extreme temperatures are not
encountered. The area should be readily accessible with sufficient room to easily install
and maintain the control panel. Locate the top of the cabinet approximately five feet
above the floor with the hinge mounting on the left.
Determine the number of conductors required for the devices to be installed and
determine the appropriate knockouts. All wiring must be in accordance with the
National and/or Local codes for fire alarm systems and power supplies.
