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 particles may be drawn into air returns before reach-
ing 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 cause interference to radio communications. It has been tested and
found to comply with the limits for class A computing device pursuant to Subpart B of Part 15 of FCC Rules, which
is designed to provide reasonable protection against such interference when operated in a commercial environ-
ment.
Operation of this equipment in a residential area is likely to cause interference, in which case the user will be re-
quired to correct the interference at his own expense.

Product Description
10 Document #15140 Rev.G 01/02/02 P/N 15140:G
CHAPTER 1 Product Description
The MS-5024UD is a combination FACP (Fire Alarm Control Panel) and DACT (Digital Alarm Communicator
Transmitter) all on one circuit board. It is a five-zone panel which uses conventional input devices. The panel
accepts waterflow devices, two-wire smoke detectors, four-wire smoke detectors, pull stations and other normally
open contact devices. Outputs include two NACs (Notification Appliance Circuits), alarm and trouble relays, super-
visory and communicator failure relay drivers.
The integral communicator transmits system status (alarms, troubles, AC loss, etc.) to UL-listed Central Stations via
the public switched telephone network. The control panel has a built-in programmer and may also serve as a slave
communicator to a host panel. It also supervises all wiring, AC voltage, telephone line input voltage and battery
level.
The control panel may be programmed or interrogated off-site via the public switched telephone network. Any IBM
compatible personal computer with DOS™4.01 or greater plus Windows™3.1 or greater, with a 1200 baud Hayes™
compatible modem and Fire•Lite Upload/Download software P/N PK-5024UD, may serve as a Service Terminal.
This allows download of the entire program or upload of the entire program, history file, walktest data, current status
and system voltages. The MS-5024UDE offers the same features as the MS-5024UD but allows connection to 220/
240 VAC input.
