MODEL USI-5204
(Part #USI-5204HA)
COMMERCIAL RESIDENTIAL (UTHA)
SMOKE & FIRE ALARM WITH SILENCE CONTROL
READ ALL INSTRUCTIONS
The smoke alarm has a recommended service life of at least 10 years under normal conditions.
The smoke alarm uses an extremely small amount of a radioactive element in the ionization
chamber. Do not tamper with radioactive sealed source or try to repair the smoke alarm
yourself. Refer to instructions for repairs.
SMOKE ALARM LIMITATIONS AND FUNCTIONS
•
THERE ARE TWO BASIC SMOKE ALARM TYPES - IONIZATION AND PHOTOELECTRIC.
Ionization smoke alarms are your best overall choice for reliability and fast response time,
since they quickly sense small "invisible" smoke particles and will also sense larger "visible"
smoke particles. Photoelectric smoke alarms may respond more quickly in certain types of
fires, for example - slow smoldering fires with large "visible" smoke particles. ALLTYPES OF
SMOKEALARMS HAVE LIMITATIONS. NO TYPE OF SMOKEALARM CAN SENSE EVERY
KIND OF FIRE OR SMOKE EVERY TIME.

WARNING - SMOKEALARMS WILLNOTWORK DURINGALOSS OF POWER. SINCEASMOKE
ALARM WILL NOT WORK WITHOUT POWER, having an alarm(s) that works from two completely
different power sources, such as anAC direct wire with battery backup smoke alarm, can give you an
extra measure of protection in case of anAC power failure or a dead battery.
USING A SMOKE ALARM IN A SMOKY AREA LIKE A KITCHEN, OR IN A HIGH HUMIDITY
AREA NEAR A SHOWER, CAN CAUSE FALSE ALARMS. DO NOT TURN OFF THE AC
POWER TO QUIET THEALARM. ASMOKE ALARM WILL NOT HELP PROTECT YOU IF IT
IS NOT POWERED. Properly locate your alarm to avoid nuisance alarms.

•
•
INSTALLING SMOKE ALARMS MAY MAKE YOU ELIGIBLE FOR LOWER INSURANCE
RATES, but SMOKE ALARMS ARE NOT A SUBSTITUTE FOR INSURANCE. Homeowners
and renters alike should continue to insure their lives and properties.
SMOKEALARMS CANNOT WORK WITHOUT POWER. Battery operated units cannot work if the
batteries are missing, disconnected or dead, if the wrong type of batteries are used or if the batteries
are not installed correctly. AC (only) powered units cannot work if the AC power is cut off for any
reason. If you are concerned about the limitations of battery orAC power, install both types of units.
SMOKE ALARMS CANNOT DETECT FIRES IF THE SMOKE DOES NOT REACH THEM.
Smoke from fires may not reach the sensing chamber and set off the alarm. One unit should
be installed inside each bedroom or sleeping area.
•
•
SMOKE ALARMS MAY NOT DETECT FIRE ON ANOTHER FLOOR OR AREA OF THE
HOME. Recommended minimum protection is at least one unit in every sleeping area and
every bedroom on every level of your home. Interconnected units may provide earlier warning
than stand-alone units since all units alarm when one detects smoke.
•
SMOKEALARMS MAYNOT BE HEARD. The alarm horn in this unit meets or exceeds current
standards, but it may not be heard if: (1) the unit is located outside a closed or partially closed
door; (2) residents recently consumed alcohol or drugs; (3) the alarm is drowned out by noise
from stereos, TV's, air conditioners or other appliances or (4) if residents are hearing impaired
or sound sleepers.
•
•
•
•
SMOKE ALARMS ARE NOT FOOLPROOF. You must test the unit weekly to ensure your
continued protection. Smoke alarms cannot prevent or extinguish fires.
SMOKEALARMS HAVEA LIMITED LIFE. The unit should be replaced immediately if it is not
operating properly. You should always replace a smoke alarm after 10 years.
SMOKE ALARMS ARE NOT TO BE USED WITH DETECTOR GUARDS UNLESS THE
COMBINATION HAS BEEN EVALUATED AND FOUND SUITABLE FOR THAT PURPOSE.

AVOID THESE LOCATIONS
•
•
the garage – products of combustion are present when you start your automobile.
near appliances or areas where normal combustion regularly occurs (kitchens, near furnaces,
gas hot water heaters). Use smoke alarms with Silence Control for these areas.
in areas with high humidity, like bathrooms or areas near dishwashers or washing machines.
Install at least 3 feet (0.9 meters) away from these areas.
•
•
•
in areas of turbulent air such as air returns or heating and cooling supply vents, smoke alarms
shall not be located where airflow prevents operation of the alarms.
in extremely dusty, dirty or insect-infested areas. Loose particles interfere with smoke alarm
operation.
•
•
in areas where temperature may fall below 400F (4.40C) or rise above 1000F (37.80C).
closer than 1 foot (0.3m) from fluorescent lights, electrical "noise" and flickering may affect the
alarm's operation.
•
•
closer than 3 feet (0.9m) horizontal path from the tip of the blade of a ceiling suspended (paddle)
fan.
on a poorly insulated ceiling or exterior wall (mount smoke alarm on an inside wall).
THIS SMOKE ALARM WILL NOT WORK WITHOUT 120 VAC POWER AND A
GOOD BATTERY PROPERLY INSTALLED. THE SMOKE ALARM SHOULD BE
TESTED WHEN INSTALLED AND THEN TESTED WEEKLY AFTER THAT.
FALSEALARMS
The smoke alarm is designed to minimize false alarms. Smoking will not normally set off the alarm
unless smoke is blown directly into the smoke alarm. Combustion particles from cooking may set
off the alarm if the smoke alarm is located close to the kitchen cooking surface. Large quantities of
combustion particles are generated from spills or broiling.
If the smoke alarm does sound, check for fires first. If a fire is discovered, get out and call the fire
department. If no fire is present, check to see if one of the reasons listed above may have caused
the alarm. Use the "silence" feature if it is a false alarm.
INSTALLATION AND OPERATION
INSTALLATION INSTRUCTIONS: CAUTION!! READ CAREFULLY.
CAUTION: THIS UNIT IS SEALED. THE COVER IS NOT REMOVABLE!
•
•
A mounting plate is provided on the back of the alarm.
Remove the mounting plate from the back of the alarm by holding the mounting plate and twisting
the alarm in the direction indicated by the "TURN TO REMOVE" arrow on the side of the alarm
base.
Installation of this unit must conform to the electrical codes in your area; Article 760 of the
National Electrical Code, NFPA 72, 101; SBC (SBCCI); UBC (ICBO); NBC (BOCA): OTFDC
(CABO), and any other local or building codes that may apply. Wiring and installation must
be performed by a licensed electrician. Failure to follow these guidelines may result in injury
or property damage.
This unit must be powered by a 24-hour, 120V AC 60Hz circuit. Be sure the circuit cannot be
turned off by a switch, dimmer or ground fault circuit interrupter. Failure to connect this unit
to a 24-hour circuit may prevent it from providing constant protection.
IMPORTANT: Do not subject this smoke alarm to megger, high voltage or high-pot tests.
Remove the smoke alarm(s) before high-potting tests occur on the circuit or system.
(Ref. Section 550-17, National Electric Code, 2002 Edition).
ELECTRICAL SHOCK HAZARD
Turn off power to the area where you will install this unit at the circuit breaker or fuse box
before beginning installation. Failure to turn off the power before installation may result in
serious electrical shock, injury or death.
TAMPER LOCKING PIN: To make your alarm somewhat tamper resistant, a locking pin has been
provided (break-away part of mounting plate). Using this tamper pin will deter children and others
from removing the alarm from the mounting plate. To use the tamper pin, insert it into the hole in the
side of the alarm after the alarm has been installed on the mounting plate. Using long nose pliers,
pull the tamper pin out of the hole. It is now possible to remove the alarm from the mounting plate.

2. Wiring Instructions:
a. The appropriate power supply is 120 Volt single phase power supplied from a non-switchable
circuit NOT protected by a ground fault circuit interrupter.
b. Turn off main power to the circuit before wiring the smoke alarm.
c. There are three pigtail leads (black, white and yellow) coming from the AC QUICK
CONNECTOR. The proper wire connection is as follows:
WIRES FROM QUICK CONNECTOR
CONNECT TO
BLACK
WHITE
YELLOW
"HOT" side of AC line
"NEUTRAL" side of AC line
Interconnect wires of other units
For units that are used as single smoke alarms, do not connect the yellow wire to anything. Insulate
this wire (tape it) in place to make certain the yellow wire cannot contact any metal parts.
Interconnected units can provide earlier warning of fire than stand-alone units, especially if
a fire starts in a remote area of the dwelling. This smoke alarm may be interconnected with
as many as 11 other USI ELECTRIC model smoke alarms such as USI-1103, USI-1203, USI-
1204, USI-1209, USI-1213, USI-2204, USI-3204 and 6 other units which may be a combination
of Carbon Monoxide Alarms such as USI-7385, USI-7390, USI-7485, USI-7490, USI-7795, Heat
Alarms/USI-2430 or Relay Modules/USI-960 for a total of not more than 18 interconnected
devices.
Interconnected CO alarms will only respond if a CO alarm / event initiates the alarm. All other
alarms remain silent.
Interconnected smoke alarms, heat alarms and relay modules will only respond if a smoke
alarm / event or heat alarm / event initiates the alarm. All CO alarms remain silent.
Note that units without battery backup will not respond during an AC power failure.
NOTE: Relay Modules/USI-960 will not respond if a CO alarm / event initiates the alarm.
INPUT:
120 VAC
60 HZ
.05A
The yellow wire is used only for multiple station operation with USI ELECTRIC Model alarms
only. Connecting this yellow wire to any other circuits may result in damage. When alarms
are interconnected, all units must be powered from a single AC branch circuit. If local codes
do not permit be sure the neutral wire is common to both phases. The maximum wire run
distance between the first and last alarm/device in an interconnected system is 1,000 feet.
NOTE: Use standard household wire (18 gauge or larger, rated at least 300V, as required by
local codes) available at all electrical supply/hardware stores.
The wiring to be used shall be in accordance with the provisions ofArticles 210 and 300.3(B)
of the National Electrical Code, ANSI/NFPA70. In addition, the resistance of the interconnecting
wiring shall be a maximum of 10 Ohms.
Early warning fire detection is best achieved by the installation of fire detection equipment in
all rooms and areas of the household as follows: A smoke alarm installed in each separate
sleeping area (in the vicinity of, but outside of, the bedrooms) and heat or smoke alarms in
living rooms, dining rooms, kitchens, hallways, attics, furnace rooms, closets, utility storage
rooms, basements and attached garages. Test the smoke alarm weekly to assure proper
operation.
3. Attach the mounting plate to the electrical junction box.
4. To activate 9 volt battery and alarm, hold the QUICK DRAW(R) battery drawer closed, pull and
remove the PULL-TAB. Discard PULL-TAB.

7. Turn on AC power and check the LED's for proper operation. The green LED lights to indicate
AC power. The red LED will flash every 40-60 seconds to indicate proper operation.
OPERATION, TESTING & MAINTENANCE
OPERATION: The smoke alarm is operating once the power is connected and turned on (the battery
must also be installed). When products of combustion are sensed, the unit sounds a loud alarm
which continues until the air is cleared.
This alarm incorporates the internationally recognized horn signal for evacuation. During alarm
mode, the horn produces three short beeps followed by a two second pause and then repeats.
STANDBY CONDITION: The red LED flashes once every 40-60 seconds to indicate the unit is
properly functioning.
LOCAL ALARM CONDITION: The red LED flashes rapidly and the unit emits a loud, pulsating
alarm sound.
REMOTE ALARM CONDITION: The red LED is off and the unit emits a loud, pulsating alarm.
GREEN LED: The green LED is on whenever AC power is turned on.
TESTING: Test by pushing the test button on the smoke alarm cover until the alarm sounds, then
release. The alarm sounds if all electronic circuitry, horn and battery are working. The alarm may
continue to sound for up to 10 seconds after the button is released. If no alarm sounds, the unit may
have a defective battery or other failure. Test the smoke alarm weekly to assure proper operation.
NEVER use an open flame of any kind to test this unit. You might accidentally damage or set
fire to the unit or to your home. The built-in test switch accurately tests the unit's operation
as required by Underwriters Laboratories Inc. (UL).
(UTHA) Sensitivity Indicating Means
The sensitivity indicating means for this Smoke and FireAlarm is the use of the analyzer for Smoke
Detectors Model 501-A or 501-A/Bat Aerosol Generator Manufactured by Gemini Scientific Corp.,
1122-B Aster Ave., Sunnyvale, CA 94086.
The Equivalent UL 268 Light obscuration %/Ft as measured by this instrument must be between
1.55% Obs./Ft. and 0.85% Obs./Ft (1.20 + 0.35% Obs./Ft.).
(UTHA) Go/No-Go Field Test
The Go/No-Go test for this Smoke and FireAlarm is the use of a UL Listed can type aerosol smoke
detector tester. The instructions for the use of this tester are given on the container.
If you choose to use an aerosol smoke product to test the smoke alarm, be certain to use one
that has been Listed to Underwriters Laboratories, Inc. Safety Standards and use it only as
directed. Use of non-UL Listed products or improper use of UL Listed products may affect
the smoke alarm's sensitivity.
FALSE ALARMS "SILENCE" CONTROL: Units with the "silence" feature have the capability of
temporarily reducing the sensitivity of the alarm circuit for approximately 3-9 minutes. This feature is
to be used only when a known alarm condition such as smoke from cooking activates the smoke
alarm. The smoke alarm "silence" feature is activated by pushing the Hold to Silence button on the
smoke alarm cover for at least three seconds. The smoke alarm will automatically reduce sensitivity
and the red LED will light for approximately 3-9 minutes to indicate the alarm is in the temporary
silent condition. The smoke alarm will gradually regain normal sensitivity and sound the alarm if
particles of combustion are still present. The "silence" feature may be used repeatedly until the air
has cleared.

Before using the alarm "silence" feature, identify the source of smoke and be certain that
safe conditions exist.
(UTHA) MAINTENANCE:
The smoke alarm is virtually maintenance free. However, under dusty conditions, a vacuum hose
may be used to clear the sensing chamber of dust.
Clean the smoke alarm at least once a month to remove dust, dirt or debris.Always turn off power
to smoke alarm before cleaning. Using a soft brush or wand attachment to a vacuum cleaner,
vacuum all sides and cover of smoke alarm. Be sure all the vents are free of debris.
If the smoke alarm is false alarming and cannot be restored to normal operation, the smoke alarm
should be replaced.
BACKUP BATTERY REPLACEMENT
Disconnect AC power before changing battery. Shock hazard exists if AC power is miswired.
The smoke alarm uses a 9 Volt battery. The battery should last for at least one year under normal
operating conditions. The smoke alarm has a low battery indicator, an audible "beep." It will operate
at 30-40 second intervals for a minimum of 7 days. When this indication occurs, replace the battery
with anAlkaline type (Eveready Energizer #522, Duracell #MN1604), Carbon-Zinc type (Gold Peak
#1604P, Eveready #216). Use the convenient QUICK DRAW(R) pull-out batterydrawer for easy battery
replacement.
Pull the QUICK DRAW(R) battery drawer open and remove the battery. While observing polarity,
push the replacement battery into the battery drawer until it is held securely in place. Carefully close
and latch the battery drawer.
REPAIRS AND SERVICES
The smoke alarm contains less than 1 microcurie (37 kilobecquerel) ofAmericium 241, a radioactive
material. The distribution of these ionization-type smoke alarms is licensed by the U.S. Nuclear
Regulatory Commission; the consumer is exempt from any licensing or requirements. If the
smoke alarm is defective in any way, do not tamper with the unit. Return the unit for servicing. (See
warranty for instructions or in-warranty returns.) There will be a service charge for repairing out of
warranty units.

DEVELOP AND PRACTICE A PLAN OF ESCAPE
BASICS OF ESCAPE PLAN
o
Make a floor plan indicating all doors and windows and at least two escape routes from each
room. Second story windows may need a rope or chain ladder.
o
Have a family meeting and discuss your escape plan, showing everyone what to do in case of
fire.
o
o
Determine a place outside your home where all of you can meet if a fire occurs.
Familiarize everyone with the sound of the smoke alarm and train them to leave your home when they
hear the sound.
o
o
Identify children's bedrooms with red stickers placed in the upper left corner of the windows. They
are available from your local fire department.
Practice a fire drill at least every six months. Practice allows you to test your plan before an
emergency. You may not be able to reach your children. It is important they know what to do!
WHAT TO DO WHEN THE ALARM SOUNDS
o
Leave immediately by your plan of escape. Every second counts, so don't waste time getting
dressed or picking up valuables.
o
In leaving, don't open any inside door without first feeling its surface. If hot, or if you see smoke
seeping through cracks, don't open that door! Instead, use your alternate exit. If inside door is
cool, place your shoulder against it, open it slightly and be ready to slam it shut if heat and smoke
rush in.
o
o
o
o
Stay close to the floor if air is smoky. Breathe shallowly through a cloth, wet if possible.
Once outside, go to your selected meeting place and make sure everyone is there.
Call the fire department from your neighbor's home – not from yours!
Don't return to your home until fire officials say that it is all right to do so.
NATIONAL FIRE PROTECTION ASSOCIATION REQUIRED PROTECTION
For your information, the National Fire Protection Association's Standard 72, reads as follows:
“11.5.1 One- and Two-Family Dwelling Units. 11.5.1.1 Smoke Detection.
Where required by applicable laws, codes, or standards for the specified
occupancy, approved single- and multiple-station smoke alarms shall be
installed as follows: (1) In all sleeping rooms. Exception: Smoke alarms
shall not be required in sleeping rooms in existing one- and two-family
dwelling units. (2) Outside of each separate sleeping area, in immediate
vicinity of the sleeping rooms. (3) On each level of the dwelling unit, including
basements. Exception: In existing one- and two-family dwelling units,
approved smoke alarms powered by batteries are permitted.
“A.11.8.3 Are More Smoke Detectors Desirable? The required number of
smoke detectors might not provide reliable early warning protection for those
areas separated by a door from the areas protected by the required smoke
detectors. For this reason, it is recommended that the householder consider
the use of additional smoke detectors for those areas for increased
protection. The additional areas include the basement, bedrooms, dining
room, furnace room, utility room, and hallways not protected by the required
smoke detectors. The installation of smoke detectors in kitchens, attics
(finished or unfinished), or garages is not normally recommended, as these
locations occasionally experience conditions that can result in improper
