to observe correct polarity, and do not force the batteries into the
compartment. The LED indicator should flash once every 7 seconds,
indicating normal operation.
Note: If the batteries are not installed correctly, the smoke detector will not
function.
3. Install the smoke detector back onto the mounting bracket, as indicated in
step 3 of
Detector Mounting Procedure on a previous page, and test its
operation as described in
TESTING THE SMOKE DETECTOR.

NFPA RECOMMENDATIONS REGARDING SMOKE DETECTOR
INSTALLATION
For your information, the National Fire Protection Association's Standard 74,
Section 204 reads as follows: "2-4.1.1; Smoke detectors shall be installed outside
of each separate sleeping area and 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. The provisions of 2-4.1.1 represent
the minimum number of detectors required by this standard. It is recommended
that the householder consider the use of additional smoke or heat detectors for
increased protection for those areas separated by a door from the areas
protected by the required smoke detectors under 2-4.1.1 above. The
recommended additional areas are: living room, dining room, bedrooms(s),
kitchen, attic (finished or unfinished), furnace room, utility room, basement,
integral or attached garage, and hallways not covered under 2-4.1.1 above.
However, the use of additional detectors remains the option of the householder."
This equipment should be installed in accordance with this standard (National
Fire Protection Association, Batterymarch Park, Quincy, MA 02269). State and
local codes and ordinances may conflict with the above standard. We suggest
you contact your local fire authority for local requirements regarding smoke
detectors.
RECOMMENDED LOCATIONS FOR SMOKE DETECTORS
To minimize the risk of fire causing injury, loss of life or loss of property, detectors
should be located on every level of a residence – basements, first floor, second
floor and attic if it is furnished – and in every separate sleeping area. More
specifically, detectors should be located:
1. Between sleeping areas and potential sources of fire such as kitchen, garage,
basement or utility room. In homes with only one sleeping area on one floor, a
detector should be put in the hallway outside the bedrooms as shown below.
In single floor homes with two separate sleeping areas, two detectors are
required, one outside each bedroom area as shown below. In multi-level
homes, detectors should be located in bedroom areas and at every
finished level of the home as shown below. Basement level detector should
be located in the bottom of basement stairwells. Second floor detectors
should be located at the top of the first-to-second floor stairwell so long as no
door or other obstruction blocks the path of smoke.
2. Inside every bedroom where a smoker sleeps or an electrical appliance is
operated. This detector should be in addition to the hallway detectors as
described above.
3. Inside all bedrooms where people sleep with the door closed. Smoke and
poisonous combustion gases are significantly blocked by a closed door. This
detector should be in addition to the hallway detectors described above.
4. At each end of a hallway serving the bedrooms if the hallway is in excess of
40 feet (12m) in length.
WHERE NOT TO LOCATE DETECTORS
To avoid false alarms and/or improper operation, avoid installation of smoke
detectors in the following areas:
• KITCHENS - smoke from cooking may cause a nuisance alarm. LOCATE
DETECTORS AT LEAST 20 FEET (6m) FROM KITCHENS IF POSSIBLE.
• IN AIRSTREAMS PASSING BY KITCHENS - smoke from cooking may enter
normal air movement paths between outlets and returns if these paths run by
kitchens, causing a nuisance alarm. LOCATE DETECTORS AWAY FROM
SUCH AIRSTREAMS IF POSSIBLE.
• BATHROOMS - excessive steam from a shower may cause a nuisance alarm.
LOCATE DETECTORS AT LEAST 10 FEET (3m) FROM BATHROOMS IF
POSSIBLE.
• NEAR FORCED AIR DUCTS used for heating or air conditioning - air
movement may prevent smoke from reaching the detector.
• NEAR FLUORESCENT LIGHT FIXTURES - "noise" generated by these
fixtures may cause a nuisance alarm.
• NEAR FURNACES OF ANY TYPE - air and dust movement and normal
combustion products may cause a nuisance alarm.
• THE PEAK OF AN "A" FRAME TYPE OF CEILING - "Dead Air" at the top may
prevent smoke from reaching the detector.
• GARAGES - products of combustion are present from running automobile
engines and may cause a nuisance alarm.
