SMOKEALARM LIMITATIONSAND FUNCTIONS
• THEREARETWO BASIC SMOKEALARM TYPES - IONIZATIONAND 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. ALL TYPES OF SMOKE ALARMS HAVE LIMITATIONS. NO TYPE OF SMOKE
ALARM CAN SENSE EVERY KIND OF FIRE OR SMOKE EVERY TIME.
• WARNING - SMOKE ALARMS WILL NOT WORK DURING A LOSS OF POWER. SINCE A
SMOKE ALARM WILL NOT WORK WITHOUT POWER, having an alarm(s) that works from two
completely different power sources, such as an AC direct wire with battery backup smoke
alarm, can give you an extra measure of protection in case of an AC power failure or a dead
battery.
• USINGASMOKE ALARM INASMOKYAREALIKEA KITCHEN, OR IN A HIGH HUMIDITY
AREA NEAR A SHOWER, CAN CAUSE FALSE ALARMS. DO NOT TURN OFF THE AC
POWER TO QUIETTHEALARM.ASMOKEALARM WILL NOTHELP PROTECTYOU IF IT
IS NOT POWERED. Properly locate your alarm to avoid nuisance alarms.

FIRE PREVENTION IS YOUR BEST SAFEGUARD.
• INSTALLING SMOKE ALARMS MAY MAKE YOU ELIGIBLE FOR LOWER INSURANCE
RATES, but SMOKEALARMSARE NOTASUBSTITUTE FOR INSURANCE. Homeowners
and renters alike should continue to insure their lives and properties.
• SMOKE ALARMS 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 or AC 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.
• SMOKE ALARMS MAY NOT 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.
• SMOKE ALARMS HAVE A 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.

Mobile Home Installation:
For minimum protection, smoke alarms should be installed in compliance with H.U.D. Manufactured Home
Construction Safety Standards, Title 24 CFR, Section 3280.208 and Section 3282. For additional protection,
see Single Story Residence smoke alarm requirements/recommendations for Existing Homes and New
Construction Homes.
Note: For mobile homes built before 1978, install smoke alarms on inside walls between 4” and 12” from
the ceiling (older mobile homes have little or no insulation in the ceiling). This is especially important if the
ceiling is unusually hot or cold.
Install a smoke alarm inside each bedroom and in the hallway outside each separate sleeping area.
Page 2
RECOMMENDED LOCATION OF ALARMS
• Locatethe first smokealarmin theimmediatearea of thebedrooms.Try toprotectthe exit pathas
the bedrooms are usually farthest from an exit. If more than one sleeping area exists, locate
additional smoke alarms in each sleeping area.
• Locate additional smoke alarms to protect any stairway as stairways act like chimneys for
smoke and heat.
• Locate at least one smoke alarm on every floor level.
• Locate a smoke alarm in any area where a smoker sleeps or where electrical appliances are
operated in sleeping areas.
• Smoke, heat and other combustion products rise to the ceiling and spread horizontally. Mounting
the smoke alarm on the ceiling in the center of the room places it closest to all points in the room.
Ceiling mounting is preferred in ordinary residential construction. However, in mobile homes, wall
mountingonan inside partition is preferredtoavoidthe thermal barrierthatmayform at the ceiling.
• When mounting smoke alarm on the ceiling, locate it a minimum of 4" (10cm) from a side wall or
corner (see DiagramA).
• When mounting smoke alarm on a wall, if local codes allow, use an inside wall with the top edge
of the smoke alarm a minimum of 4" (10cm) and a maximum of 12" (30.5cm) below the ceiling/
wall intersections (See DiagramA).

THIS SMOKE ALARM WILL NOT WORK WITHOUT 120 VAC POWER AND A
GOOD BATTERY PROPERLY INSTALLED. THE SMOKE ALARM SHOULD BE
TESTED WHEN INSTALLEDAND THEN TESTED WEEKLYAFTER THAT.
FALSE ALARMS
The smoke alarm is designed to minimize false alarms. Smoking will not normally set off the alarm
unlesssmoke is blowndirectlyinto the smoke alarm. Combustionparticlesfromcookingmayset 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
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, 120VAC 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: Tomake yoursmoke alarm somewhattamper resistant, a lockingpin has
beenprovided.Usingthispinwilldeterchildrenandothersfromremovingthealarmfromthemounting
ring. To use the pin, insert it into the hole in the side of the alarm after it has been installed on the
mountingring. Note thatthetamperpin will havetobe removed inorderto change thebattery, which
can be done easily with a pair of long nose pliers. Using the long nose pliers, pull the pin out of the
hole. It is now possible to remove the smoke alarm from the mounting ring.
1. Turn thesmokealarm counterclockwise toremove it fromthemounting ring. NOTE:Thesmoke
alarmissealed and thecoveris not removable.Yoursmokealarmis also equippedwitha safety
device which prevents mounting unless a battery is installed. If your smoke alarm will not lock
onto the mounting ring, check to make sure a battery is installed.

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'soperation.
• closerthan 3feet (0.9m) horizontalpathfromthe tip of the bladeof aceiling suspended (paddle)
fan.
• on a poorly insulated ceiling or exterior wall (mount smoke alarm on an inside wall).

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 CONNECTTO
BLACK "HOT" side ofAC line
WHITE "NEUTRAL" side of AC line
YELLOW Interconnect wires of other units
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 ring to the electrical junction box.
4. To activate 9 volt battery and smoke alarm, pull and remove the thin colored plastic tab at
battery door hinge. Discard plastic tab.
5. Plug the AC QUICK CONNECTORS together. Push and turn the smoke alarm clockwise
onto the mounting ring.
6. See "TAMPER LOCKING PIN."
Page 4
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-1208, USI-1209, USI-1213, USI-2204, USI-3204, USI-5204 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: Relay Modules/USI-960 will not respond if a CO alarm / event initiates the alarm.
NOTE: Units without battery backup will not respond during an AC power failure.
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 of Articles 210 and
300.3(B) of the National Electrical Code, ANSI/NFPA 70. In addition, the resistance of the
interconnecting wiring shall be a maximum of 10 Ohms.

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:Thesmokealarmis operating once thepoweris connected andturnedon(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
properlyfunctioning.
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
continueto sound for up to10 seconds afterthe buttonis released. Ifno alarm sounds, the unitmay
haveadefectivebatteryorotherfailure.Testthesmoke 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).
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
temporarilyreducing the sensitivityof the alarmcircuit for approximately3-5minutes.This feature is
to be used only when a known alarm condition such as smoke from cooking activates the smoke
alarm.The smoke alarm is deactivated by pushing the test button on the smoke alarm cover for at
least three seconds. The smoke alarm will automatically reduce sensitivity and "beep" every 30-40
secondsfor approximately 3-5minutes to indicatethealarm isinthe temporary silentcondition.The
smokealarmwill gradually reactivateandsound the alarmifparticlesof combustion arestillpresent.
The "silence" feature may be used repeatedly until the air has cleared.
Page 5
Before using the alarm "silence" feature, identify the source of smoke and be certain that
safe conditions exist.
MAINTENANCE:Thesmoke alarmis virtually maintenancefree. However, under dustyconditions,
a vacuum hose may be used to clear the sensing chamber of dust.
Clean the smoke alarm at least once a month toremove dust, dirtordebris.Alwaysturnoffpower

all sides and cover of smoke alarm. Be sure all the vents are free of debris.

BACKUPBATTERYREPLACEMENT
DisconnectAC power before changing battery. Shock hazard exists ifAC power is miswired.
The smoke alarm uses a Long Life 9 Volt ULTRALIFE U9VL-J Lithium Powercell. The battery is
warranted for 10 years under normal operating conditions. The smoke alarm has a low battery
indicator, anaudible "beep." Itwill operate at30-40 second intervalsfor a minimumof 7 days.When
thisindication occurs, replacethe battery. Only thefollowing Lithium battery(available at mostdrug,
hardware or electronic parts stores) should be used for replacement. Lithium type: (ULTRALIFE
U9VL-J).
Push and lift the battery door latch and remove the battery from the battery door. While observing
polarity, pushthe replacement batteryinto the batterydoor until itis held securelyin place. Carefully

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 Haveafamily meeting and discussyourescapeplan, showing everyonewhattodo in case offire.
o Determine a place outside your home where all of you can meet if a fire occurs.
o Familiarize everyone with the sound of the smoke alarm and train them to leave your home when they
hearthesound.
o Identifychildren's bedrooms with redstickers placed intheupper left corner ofthewindows.They
are available from your local fire department.
o 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 THEALARM SOUNDS
o Leave immediately by your plan of escape. Every second counts, so don't waste time getting
dressed or picking up valuables.
o Inleaving, don't openany inside doorwithout first feelingits surface. Ifhot,or ifyousee smoke seeping
throughcracks,don'topenthatdoor! Instead,useyouralternateexit.Ifinsidedooriscool,placeyour
shoulder against it, open it slightly and be ready to slam it shut if heat and smoke rush in.
o Stay close to the floor if air is smoky. Breathe shallowly through a cloth, wet if possible.
o Once outside, go to your selected meeting place and make sure everyone is there.
o Call the fire department from your neighbor's home – not from yours!
o Don't return to your home until fire officials say that it is all right to do so.
