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 f or repairs.
SMOKE ALARM LIMITATIONS AND FUNCTIONS
• THERE ARE TWO BASIC SMOKE ALARM TYPES - IONIZATION AND PHO T OELECTRIC .
Ionization smoke alarms (such as this Smoke Alarm) 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 ma y 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 A C direct wire with battery backup smoke alarm, can give you an
extra measure of protection in case of an AC power f ailure 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 T O QUIET THE ALARM. A SMOKE ALARM WILL NO T HELP PRO TECT YOU IF IT
IS NOT POWERED. Properly locate your alarm to av oid nuisance alarms.
• A SMOKE ALARM MAY NOT ALWAYS WARN YOU ABOUT FIRES CAUSED BY
CARELESSNESS AND SAFETY HAZARDS LIKE SMOKING IN BED, VIOLENT
EXPLOSIONS, ESCAPING GAS, IMPROPER STORAGE OF FLAMMABLE MATERIALS,
OVERLOADED ELECTRICAL CIRCUITS , CHILDREN PLA YING WITH MATCHES, NA TURAL
CAUSES SUCH AS LIGHTNING, OR ARSON. FIRE PREVENTION IS YOUR BEST
SAFEGUARD.
• INSTALLING SMOKE ALARMS MAY MAKE YOU ELIGIBLE FOR LOWER INSURANCE
RA TES, b ut SMOKE ALARMS ARE NO T A SUBSTITUTE 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 lev el of your home. Interconnected units may pro vide earlier warning
than stand-alone units since all units alarm when one detects smoke.
• SMOKE ALARMS MAY NO T BE HEARD . The alarm horn in this unit meets or exceeds current
UL 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
continued protection. Smoke alarms cannot prev ent or e xtinguish 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.
weekly to ensure your
RECOMMENDED LOCATION OF ALARMS
• Locate the first smoke alarm in the immediate area of the bedrooms. Try to protect the exit path as
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. Howev er , in mobile homes , w all
mounting on an inside partition is preferred to avoid the thermal barrier that may form at the ceiling.
• When mounting smoke alarm on the ceiling, locate it a minimum of 4" (10cm) from a side wall or
corner (see Diagram A).
• 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 Diagram A).
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 ad ditional 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.
• 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 10 feet (3 meters) awa y from these areas.
• in areas of turbulent air such as air returns or heating and cooling supply vents. Install at least 3
feet (0.9 meters) away from these areas. The air could blow smoke away from the smok e alarm,
interrupting its alarm.
• in extremely dusty, dir ty or insect-infested areas. Loose particles interfere with smoke alarm
operation.
• in areas where temperature may fall below 40
• closer than 5 feet (1.5m) from fluorescent lights, electrical "noise" and flickering may affect the
alarm's operation.
0
F (4.40C) or rise above 1000F (37.80C).
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 .
AV OID THESE LOCATIONS
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. Comb ustion 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 ma y have caused
the alarm. Use the "silence" feature if it is a f alse alarm.
INSTALLATION
FALSE ALARMS
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 ma y appl y . Wiring and installation must
be performed by a licensed electrician. Failure to f ollow these guidelines may result in injury
or property damage.
This unit must be powered by a 24-hour , 120V A C 60Hz circuit. Be sure the circuit cannot be
turned off by a switch, dimmer or gr ound fault circuit interrupter . Failure to connect this unit
to a 24-hour circuit may prevent it from pr oviding constant pr otection.
ELECTRICAL SHOCK HAZARD
T urn off po wer to the area where you will install this unit at the circuit breaker or fuse box
before beginning installation. F ailure to turn off the power before installation ma y result in
serious electrical shock, injury or death.
TAMPER LOCKING PIN: To make your smoke alarm somewhat tamper resistant, a locking pin has
been provided. Using this pin will deter children and others from removing the alarm from the mounting
ring. To use the pin, insert it into the hole in the side of the alarm after it has been installed on the
mounting ring. Note that the tamper pin will have to be remo ved in order to change the battery , 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 possib le to remo ve the smok e alarm from the mounting ring.
1. T urn the smoke alarm counterclockwise to remove it from the mounting ring. NO TE: The smok e
alarm is sealed and the cover is not removable . Your smoke alarm is also equipped with a safety
device which prevents mounting unless a battery is installed. If y our smok e alarm will not lock
onto the mounting ring, check to make sure a battery is installed.
2. Wiring Instructions:
a. The appropriate power supply is 120 V olt single phase power supplied from a non-switchab le
circuit NOT protected by a ground f ault 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 f ollows:
WIRES FROM QUICK CONNECTOR CONNECT TO
BLACK "HOT" side of AC line
WHITE "NEUTRAL" side of AC line
YELLOW 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. If any unit in the series senses smoke, all units will
alarm. This smoke alarm may be inter connected with as many as 11 other UNIVERSAL model
smoke alarms and 6 other units which may be a combination of HD-130 Heat Alarms or RM100 Relay Modules for a total of not more than 18 interconnected devices.
The yellow wire is used
SS-790 AND SS-795 only.
only for multiple station operation with UNIVERSAL Models SS-785,
Connecting this yellow wire to any other circuits may result in
damage. When smoke alarms are interconnected, all units must be powered fr om 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 smoke alarm 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) a vailable at all electrical supply/har dware stores.
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 r ooms, 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."
7. Turn on AC power and chec k the LED's f or proper operation. The green LED lights to indicate
AC power . The red LED will flash every 40-60 seconds to indicate proper operation.
OPERATION: The smoke alarm is operating once the po wer is connected and turned on (the battery
OPERATION, TESTING & MAINTENANCE
must also be installed). When products of combustion are sensed, the unit sounds a loud alar m
which continues until the air is cleared.
This alarm incorporates the internationally recognized hor n signal for evacuation. During alarm
mode, the horn produces three short beeps followed by a two second pause and then repeats. This
pattern is somewhat different than the previous alarm sound, which continually beeped.
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 whenev er AC po wer 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. If no alarm sounds,
the unit may have a def ective battery or other failure .
NEVER use an open flame of any kind to test this unit. You might accidentall y damage or set
fire to the unit or to your home. The built-in test s witch accurately tests the unit's operation as
required by Underwriters Laboratories Inc. (UL).
Do not use aerosol smoke to test the unit. Aerosol contaminants can c log the unit and prevent
smoke from reaching the sensor in a fire emergency .
FALSE ALARMS "SILENCE" CONTROL: Units with the "silence" feature have the capability of
temporarily reducing the sensitivity of the alarm circuit for approximately 8 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 is deactivated b y pushing the test b utton on the smoke alarm cov er f or at
least three seconds. The smok e alarm will automatically reduce sensitivity and "beep" every 30-40
seconds for approximately 8 minutes to indicate the alarm is in the temporary silent condition. The
smoke alarm will gradually reactivate during the 8 minutes and sound the alarm if particles of
combustion are still present. The "silence" f eature 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.
MAINTENANCE: The smoke alarm is virtually maintenance free. Ho wev er, under dusty conditions,
a vacuum hose may be used to clear the sensing chamber of dust.
BACKUP BATTERY REPLACEMENT
Disconnect AC power before c hanging battery . Shoc k hazard exists if A C power is miswired.
The smoke alarm uses a 9 Volt carbon-zinc batter y. The batter y 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 an Alkaline type (Radio Shack Cat. No. 23-553, Eveready Energizer #522,
Duracell #MN1604), Carbon-Zinc type (Gold Peak #1604P [UL], Eveready #216), or Lithium type
(UL TRALIFE U9VL-J).
Push and lift the battery door latch and remove the battery from the battery door. While observing
polarity, push the replacement battery into the battery door until it is held securely in place. Carefully
close and latch the battery door.
REPAIRS AND SERVICES
The smoke alarm contains less than 1 microcurie (37 kilobecquerel) of Americium 241, a radioactive
material. This substance requires that the smoke alarm be returned to the manufacturer or the
Department of Health for disposal. Do not dispose of in any other way. 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 warr anty 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 Determine a place outside your home where all of you can meet if a fire occurs.
o Familiarize everyone with the sound of the smok e alarm and train them to leave your home when the y
hear the sound.
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.
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 T O 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 surf ace . If hot, or if you see smoke
seeping through cracks,
cool, place your 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 ev eryone is there.
o Call the fire department from your neighbor's home –
o Don't return to your home until fire officials say that it is all right to do so.
NA TIONAL FIRE PR O TECTION ASSOCIATION REQUIRED PROTECTION
For your information, the National Fire Protection Association's Standard 72, reads as follo ws:
"2-2.1.1.1 Smoke detectors shall be installed outside of each separate sleeping area in
the immediate vicinity of the bedrooms and on each additional story of the family living
unit including basements and excluding crawl spaces and unfinished attics. In new
construction, a smoke detector shall be installed in each sleeping room."
"A-2.5.2.1 Smoke Detection - 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 smok e detectors in kitchens,
attics (finished or unfinished), or garages is not normally recommended, as these locations
occasionally experience conditions that can result in improper operation."
The equipment should be installed in accordance with the National Fire Protection Association's
Standard 72. (National Fire Protection Association, Batterymarch Park, Quincy, MA 02269).
don't open that door!
Instead, use your alternate exit. If inside door is
not from yours!
