Ionization Smoke Alarms are generally more effective at detecting flaming
fires, which consume combustible materials rapidly and spread quickly.
Sources of these fires may include paper burning or a grease fire.
Photoelectric Smoke Alarms are generally more effective at detecting
smoldering fires, which smolder for hours before bursting into flame. Sources
of these fires may include cigarettes burning in couches or bedding.
For Maximum protection, use both types of smoke alarms on each level
of your home.
INSTALLER: Please leave this manual
with the smoke alarm
• Smoke Alarms can only work if they are properly located, installed,
and maintained, and if smoke reaches them. They are not
• This Alarm meets the 10/1/1999 UL standard for a new horn "alarm"
pattern for smoke alarms. This sound is different than other Smoke
Alarms you may have installed or may have heard in other locations.
You must test this alarm and educate all members and guests of the
residence or business of this different horn pattern.
• Different Smoke Alarm Sounds. If this unit replaces another 9 volt
smoke alarm or is being used for additional protection where other
smoke alarms are present, than everyone who might hear this alarm
must be made aware of the different smoke alarms horn sounds.
• 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 units cannot work if the AC power is cut off by an electrical
fire, an open fuse, a circuit breaker or any other 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. Anything preventing smoke from reaching the alarm may delay, or
prevent an alarm. A smoke alarm cannot detect fire in the walls,
chimney or roof unless and until a significant amount of smoke reaches
the alarm. A closed door may prevent smoke from reaching an alarm on
the other side of the door. Smoke alarms may not sense fire on another
level or floor of a residence. That is why you should install alarms on all
levels and in each sleeping area of a residence. When possible install
interconnected alarms Interconnected units may provide earlier warning
than stand-alone units since all units alarm when one detects smoke.
• Smoke Alarms may not be heard. Though the alarm horn in this unit
meets or exceeds current UL standards, it may not be heard for many
reasons These include, but are not limited to: the unit is located outside
a closed or partially closed door, residents recently consumed alcohol or
drugs, the alarm is drowned out by other noise like the TV, stereo,
traffic, weather, air conditioner or other appliances, residents are hearing
impaired or sound sleepers.
• Smoke alarms have a limited life and are not foolproof. Smoke
alarms will wear out over time like any appliance. Test your alarm at
least once per week Always replace detectors immediately if they are
not working properly, if they display any type of problem or prior to 10
years of use. They are not a substitute for property or life insurance
• Smoke alarms may not have time to alarm before the fire causes
damage, injury or even death. Examples of this include persons
smoking in bed, children playing with matches or lighters, fires caused
by violent explosions, natural causes like lighting, arson, escaping gas,
overloaded electrical circuits, carelessness or by other safety hazards
• Never disconnect the battery to silence the alarm.
• This unit will not alert hearing-impaired residents. Special Alarms
with flashing strobe lights are needed for the hearing impaired.
• This is a single station alarm. Do not attempt to connect this to any
other device
• Do not install this alarm over an electrical box. Do not use this
detector as a replacement for an AC or AC/DC smoke alarm. Only use
as an additional alarm for greater protection or as a replacement for a
battery operated smoke alarm.
• Caution -Do not paint this unit. Paint may clog the openings to the
sensing chamber and will prevent the unit from working properly.
• Caution -Do not stand too close to the unit when testing, silencing or
during an alarm as the loud horn could damage your hearing. When
testing move away when the horn starts sounding.
• Caution -This smoke alarm is not designed for buildings, which require
complete fire alarm systems. Buildings of this type include but are not
limited to hotels, motels, dormitories, hospitals, nursing homes and group
homes. This applies to single-family homes that have been converted for
any of these uses.
• Caution -This smoke alarm may not give adequate warning to those with
physical limitations of any kind. Additional measures should be taken to
insure their safe evacuation if a fire does occur. Install a professional fire
alarm system that is connected to a call center. If possible, keep them on
the ground level with more than one escape route available to them.
• Caution -Smoke alarms sound their horns when they detect smoke. They
do not detect heat, flame or gas. They will not operate if smoke does not
reach them.
Practice Fire Safety
Putting up smoke alarms is just one part of protection against fires. You must
also reduce the chances of a fire starting and have a plan that you have
practiced for everyone escaping if a fire does occur.
Escape Planning
• Make a floor plan indicating all doors and windows and plan at least two
escape routes from each room. Upper story rooms may require a rope or
chain ladder for safe escape.
• Have a meeting and discuss your escape plan, showing everyone what to
do in case of fire.
• Determine a meeting location outside the building/RV/Boat where you can
safely meet if a fire does occur.
• Familiarize everyone with the sound of this smoke alarm and all other
smoke alarms in the building/RV/Boat. Train everyone to safely leave the
building/RV/Boat when they hear the smoke alarm(s).
• Update and practice your escape plan at least every six months. Inform
guests and others of your plan and meeting place.
• Teach everyone how to check doors and not to open them if they are hot.
Also to stay low and not to breath smoke, fumes or gases.
What to do when the alarm sounds.
Warning -Never ignore any alarm. If the alarm sounds and you are not
absolutely certain of the source of the smoke, get everyone out of the
house/RV/Boat immediately.
• Leave immediately by your plan of escape. Every second counts, do not
waste time getting dressed (except life vests if needed) or picking up
• Feel doors before opening them to see if they are hot. If a door is cool,
open it slowly and check for fire and heat before you proceed. Do not
open a hot door - use an alternate escape route.
• Stay close to the floor if air is smoky, Take short shallow breaths through a
wet cloth if possible.
• Once outside, go to your selected meeting place and make sure everyone
is there.
• Call the Fire Department from outside of the building with the activated
alarm, at a safe location•
Do not return to your home until fire officials say that it is safe.
Series SA-668 Smoke Alarms are single station alarm devices and should
not be connected to other detection units. This equipment should be installed
in accordance with the National Fire Protection Association's Standard No 72
and NFPA 302 if installed on a boat.
For your information the National Fire Protections Association's
Standard reads as follows:
"2-2 111 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"
"2-22 1 In new construction, where more than one smoke detector is
required by 2-2 1, they shall be so arranged that operation of any
smoke detector shall cause the alarm in all smoke detectors within
the dwelling to sound"
"A-2521 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 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 operation".
Additionally, the California State Fire Marshal states that the
minimum number of required smoke alarms in not enough to give:
the earliest warning under all conditions. The California Sate Fire
Marshal states: "Early warning detection is best achieved by the
installation of fire detection equipment in all rooms and areas of the
household as follows: smoke alarm installed in each separate
sleeping area (in the vicinity, by outside bedrooms), and heat or
smoke alarms in the living rooms, dinning rooms, bedrooms,
kitchens, hallways, finished attics, furnace rooms closets, utility and
storage rooms, basements, and attached garages"
Additional local building and regulatory codes may apply in your
area Specific requirements for smoke alarm installation vary from
state to state and from area to area. Check with you local Fire
Department for current requirements where you live If you install
AC or AC/DC units, it is recommended that they be interconnected
for added protection.
Smoke Alarm Placement in Single Family Dwellings
Minimum coverage, as recommended by the National Fire
Protection Association (NFPA), is one smoke alarm on every floor,
in every sleeping area, and in every bedroom. In new construction,
the smoke alarms must be AC powered and interconnected. See
above for details
For added coverage, it is recommended that you install a smoke
alarm in all rooms, halls, storage areas, finished attics and
basements where temperatures normally remain between 40 F and
100 F (4.4 C and 37.8 C). Make sure no door or other obstacle
could keep smoke from reaching the alarm
See home drawing for further information.
Install Smoke Alarms:
• On every level of your home, including finished attics and
• Inside every bedroom, especially if occupants sleep with the door
partly or completely closed.
• In basements, install a smoke alarm on the ceiling at the
bottom of the stairwell.
• Install smoke alarms on peaked, cathedral, or gabled ceilings 3
feet from the highest point (measured horizontally). Install a smoke
alarm in each room that is divided by a partial wall (either coming
down from the ceiling at least 8 inches or coming up from the floor).
ƒ Install a smoke alarm as close to the center of the ceiling as
possible. If this is not practical, install no closer than 6 inches from the wall
or corner. Also, if local codes allow wall mounting, install alarms on walls
between 4 and 5 inches from ceiling/wall intersections.
ƒ At the top of the first-to-second floor stairway.
ƒ In the hall near every sleeping area. If the dwelling has multiple sleeping
areas, install a unit in each area. If a hall is more than 30 feet long; install
a unit at each end.
Smoke Alarm Placement in Mobile Homes and RVs/Boats
Mobile homes and RVs/Boats built after 1978 were designed and insulated
to be energy efficient. In mobile homes and RVs/Boats built after 1978,
smoke alarms should be installed as described in previous section - "Smoke
Alarm Placement in Single Family Dwellings".
Older mobile homes and RVs/Boats may have little or no insulation
compared to today's standards. Outside walls and roofs are often made on
poorly insulated metal, which can transfer head and cold from outdoors.
This makes the air right next to them hotter or colder than the rest of the
inside air. These layers of hotter or colder air can keep some from reaching
a smoke alarm
Therefore, install smoke alarms in such units only on inside walls. Place
them between 4 and 6 inches (10 to 15 cm) from the ceiling. If you are
unsure how much insulation is in your mobile home or RV, put the alarm on
an inside wall. Or if you notice that the walls or ceiling are not unusually hot
or cold, put the alarm on the inside wall.
For minimum security, install one alarm as close to the sleeping area as
possible. For more security place one alarm in each room. Before you put
up any alarms read the section in this manual -"Locations Where Smoke
Alarms Should NOT Be Installed". See RV/Boat drawing for further
of combustion particles (stove, furnace, water heater, space heater, etc.)
if possible. Ventilate these areas as much as possible.
In air streams near kitchens. Air currents can draw cooking smoke into
the sensing chamber of a smoke alarm near the kitchen.
In very damp humid or steamy areas, or directly near bathrooms with
showers. Keep units at least 10 feet away from showers, saunas,
dishwashers, etc.
Where the temperatures are regularly below 40o F or above, 100o F,
including unheated buildings, outdoor rooms, porches, or unfinished
attics or basements.
In very dusty, dirty or greasy areas. Do not install a smoke alarm directly
over the stove or range. Clean a laundry room unit frequently to keep it
free of dust or lint.
Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow
smoke away from the unit, preventing it from reaching the sensing
In insect infested areas. Insects can clog the openings to the sensing
chamber and cause unwanted alarms.
Less than one foot away from fluorescent lights. Electrical "noise" can
interfere with the sensor.
"Dead air" spaces may prevent smoke from reaching the smoke alarm.
To avoid dead air spaces, install smoke alarms as close to the center of
the ceiling as possible. If this is not possible, install the smoke alarm at
least 6 inches from the wall or corner.
For wall mounting (if allowed by building codes) smoke alarms should be
placed between 4 and 5 inches from the wall I ceiling line.
On a peaked, gabled, or cathedral ceiling, keep smoke alarms at least 3
feet from the highest point (measure the distance horizontally).
power to the Alarm. When production of combustion are sensed, the unit
sounds a loud alarm which continues until the air is cleared
False Alarms "Mute" control: Models (S/SLL) with the mute feature have
the capability of temporarily reducing the sensitivity of the alarm circuit for
approximately 10 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 horn is muted by pushing and holding the test button on the
alarm cover for 5 seconds. The smoke alarm will automatically reduce
sensitivity and the LED will "flash” every 10-20 seconds for approximately 10
minutes to indicate the alarm is in temporary mute condition. The smoke
alarm is completely operational during the mute cycle and will alarm if the
smoke density increases. After the 10 minute mute cycle the alarm will
"beep" twice letting you know it has automatically returned to normal
CAUTION: Before using the "mute" feature, identify the source of smoke
and be certain that safe conditions exist.
Test the alarm by pushing the test button on the smoke alarm
cover for at least three seconds, until the alarm sounds. The alarm sounds if
