SMOKE & FIRE ALARM
with Alarm Mute
MODEL SA-775/SA-775B
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. ALL TYPES OF
SMOKE ALARMS HAVE LIMITATIONS. NO TYPE OF SMOKE ALARM 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 an AC 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 THE ALARM. A SMOKE ALARM WILL NOT HELP PROTECT YOU IF IT
IS NOT POWERED. Properly locate your alarm to avoid alarms.
•ASMOKEALARM MAYNOTALWAYS WARN YOUABOUTFIRES CAUSED BY CARELESSNESS
AND SAFETY HAZARDS LIKE SMOKING IN BED, VIOLENT EXPLOSIONS, ESCAPING GAS,
IMPROPER STORAGE OF FLAMMABLE MATERIALS, OVERLOADED ELECTRICAL CIRCUITS,
CHILDREN PLAYING WITH MATCHES, NATURAL CAUSES SUCHAS LIGHTNING, ORARSON.
FIRE PREVENTION IS YOUR BEST SAFEGUARD.
•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.
•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.
DO NOT RESTRICT AIRFLOW AROUND
THE SMOKE ALARM OR PLACE IN AREAS OF OBSTRUCTED AIRFLOW.
•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 (5) residents are sleeping.
•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.
•CURRENT STUDIES HAVE SHOWN SMOKE ALARMS MAY NOT AWAKEN ALL SLEEPING
INDIVIDUALS AND THAT IT IS THE RESPONSIBILITY OF INDIVIDUALS IN THE
HOUSEHOLD WHO ARE CAPABLE OF ASSISTING OTHERS TO PROVIDE ASSISTANCE
TO THOSE WHO MAY NOT BE AWAKENED BY THE ALARM SOUND OR TO THOSE
WHO MAY BE INCAPABLE OF SAFELY EVACUATING THE AREA UNASSISTED.

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. If a hall is more than 40 feet (12 meters) long,
install a smoke alarm at each end.
•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
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 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.

THIS SMOKE ALARM WILL NOT OPERATE WITHOUT A BATTERY INSTALLED.
PROPER BATTERY MUST BE INSTALLED IMMEDIATELY WHEN LOW
BATTERY SIGNAL IS GIVEN OR THE UNIT WILL FAIL. TEST WEEKLY. READ
AND FOLLOW ALL INSTRUCTIONS OR UNIT WILL NOT OPERATE PROPERLY.
FALSE ALARMS (SEE "Alarm Mute" CONTROL)
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 alarm, 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 "Alarm Mute" feature if it is a false alarm.
INSTALLATION
Your smoke alarm is designed for easy mounting on wall or ceiling. A complete mounting kit is
included with the smoke alarm. First, attach the mounting bracket on the wall or ceiling with the
screws provided. Second, push and turn the smoke alarm clockwise on the mounting bracket.
(Note: Your smoke alarm is equipped with a safety device which prevents mounting unless a battery
is installed. If your smoke alarm will not lock into the mounting bracket, check to make sure a battery
is installed.)
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.

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 “Alarm Mute” 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).

OPERATION, TESTING & MAINTENANCE
OPERATION: The smoke alarm is operating once the battery is connected. 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.
FALSE ALARMS "Alarm Mute" Feature: Units with the "Mute" 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 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
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 "Mute" feature may be used repeatedly until the air has cleared.
CAUTION: Before using the “Alarm Mute" feature, identify the source of smoke and be
certain that safe conditions exist.
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).
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.
RV INSTALLATION -
WARNING: TEST SMOKE ALARM OPERATION AFTER VEHICLE HAS BEEN IN STORAGE,
BEFORE EACH TRIP, AND AT LEAST ONCE PER WEEK DURING USE. An identical marking is
to be provided by the recreational vehicle manufacturer that shall be permanent and located, visibly,
within 24 inches (610mm) of the smoke alarm.
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.
BATTERY REPLACEMENT
The smoke alarm comes with 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 an Alkaline type (Eveready Energizer #522, Duracell #MN1604.
REPAIRS AND SERVICES
The smoke alarm contains less than 1 microcurie (37 kilobecquerel) of Americium 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 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
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 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 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.
