IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate properly because of dead, missing or weak
batteries, a build-up of dirt, dust or grease on the Smoke Alarm cover, or
installation in an improper location. Clean the Smoke Alarm as described in
“Regular Maintenance,” and install a fresh battery, then test the Smoke Alarm
again. If it fails to test properly when you use the test button, or if the prob-
lem persists, replace the Smoke Alarm immediately.
•
If you hear a “chirp” approximately once a minute, replace the
battery.
•
If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
•
If the alarm sounds when no smoke is visible, try cleaning or
relocating the Smoke Alarm. The cover may be dirty.
•
If the alarm does not sound during testing, make sure it is receiving
AC power from the household current.
•
The Escape Light
®
bulb is not replaceable. In the unlikely event that
the Escape Light
®
does not operate during testing, please obtain
warranty service.
Always discharge the branch circuit before servicing an AC or AC/DC
Smoke Alarm. First, turn off the AC power at the circuit breaker or fuse
box. Next, remove the battery from Smoke Alarms with battery back-up.
Finally, press and hold the test button for 5-10 seconds to discharge the
branch circuit.
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
Do not try fixing the alarm yourself – this will void your warranty!
RECOMMENDED LOCATIONS
FOR SMOKE ALARMS
Installing Smoke Alarms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends 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 “Agency Placement Recommendations” for details. For additional cover-
age, 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 (4˚ C) and 100˚ F (38˚ C). Make sure no door or other
obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
•
On every level of your home, including finished attics and basements.
•
Inside every bedroom, especially if people sleep with the door partly or
completely closed.
•
In the hall near every sleeping area. If your home has multiple sleeping
areas, install a unit in each. If a hall is more than 40 feet long (12 meters),
install a unit at each end.
•
At the top of the first-to-second floor stairway, and at the bottom
of the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to state
and from region to region. Check with your local Fire Department for current
requirements in your area. It is recommended AC or AC/DC units be inter-
connected for added protection.
AGENCY PLACEMENT RECOMMENDATIONS
NFPA 72 (National Fire Code)
Smoke Alarms shall be installed in each separate sleeping room, outside each
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, Alarms shall be so arranged that operation of any one
Alarm shall cause the operation of all Alarms within the dwelling.
Smoke Detection-Are More Smoke Alarms Desirable? The required number
of Smoke Alarms might not provide reliable early warning protection for those
areas separated by a door from the areas protected by the required Smoke
Alarms. For this reason, it is recommended that the householder consider the
use of additional Smoke Alarms 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 Alarms.
The installation of Smoke Alarms in kitchens, attics (finished or unfinished),
or garages is not normally recommended, as these locations occasionally
experience conditions that can result in improper operation.
California State Fire Marshal (CSFM)
Early warning 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, but outside bedrooms),
and Heat or Smoke Alarms in the living rooms, dining rooms, bedrooms,
kitchens, hallways, finished attics, furnace rooms, closets, utility and storage
rooms, basements, and attached garages.
LOCATIONS TO AVOID FOR SMOKE ALARMS
For best performance, AVOID installing Smoke Alarms in these areas:
•
Where combustion particles are produced. Combustion particles form
when something burns. Areas to avoid include poorly ventilated kitchens,
garages, and furnace rooms. Keep units at least 20 feet (6 meters) from
the sources of combustion particles (stove, furnace, water heater, space
heater) if possible. In areas where a 20-foot distance is not possible – in
modular, mobile, or smaller homes, for example – it is recommended
the Smoke Alarm be placed as far from these fuel-burning sources as
possible. The placement recommendations are intended to keep these
Alarms at a reasonable distance from a fuel-burning source, and thus
reduce “unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm
is placed directly next to a fuel-burning source. 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 (3 meters) away from showers,
saunas, dishwashers, etc.
•
Where the temperatures are below 40˚ F (4˚ C) or above 100˚ F (38˚ C)
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 sensing chamber.
•
In insect infested areas. Insects can clog openings to the sensing
chamber and cause unwanted alarms.
•
Less than 12 inches (305 mm) away from fluorescent lights. Electrical
“noise” can interfere with the sensor.
•
In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching
the Smoke Alarm.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke Alarm.
To avoid dead air spaces, follow the installation recommendations below.
On ceilings, install Smoke Alarms as close to the center of the ceiling as
possible. If this is not possible, install the Smoke Alarm at least 4 inches (102
mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke
Alarms should be placed between 4 inches (102 mm) and 12 inches (305
mm) from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm
within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally.
Additional Smoke Alarms may be required depending on the length, angle,
etc. of the ceiling's slope. Refer to NFPA 72 for details on requirements for
sloped or peaked ceilings.
INSTALLING SMOKE ALARMS IN MOBILE HOMES
For minimum security install one Smoke Alarm as close to each sleeping area
as possible. For more security, put one unit in each room. Many older mobile
homes (especially those built before 1978) have little or no insulation. If your
mobile home is not well insulated, or if you are unsure of the amount of insula-
tion, it is important to install units on inside walls only. Smoke Alarms should be
installed where temperatures remain between 40˚ F (4˚ C) and 100˚ F (38˚ C).
This equipment should be installed in accordance with NFPA (National Fire
Protection Association) 72 and 101. National Fire Protection Association, One
Batterymarch Park, Quincy, MA 02269-9101. Additional local building and
regulatory codes may apply in your area. Always check compliance
requirements before beginning any installation.
