SMOKE DETECTORS FOR MINIMUM SECURITY
• Install basement detectors at the bottom of the basement stairwell.
•
Install second-floor detectors at the top of the first-to-second floor stairwell. Be
sure no door or other obstruction blocks the path of smoke to the detector.
•
Install additional detectors in your living room, dining room, family room, attic,
utility and storage rooms.
•
Install smoke detectors as close to the center of the ceiling as possible. If this is
not practical, put the detector on the ceiling, no closer than 20 inches (50 cm)
from any wall or corner, as shown in Figure 5.
•
If some of your rooms have sloped, peaked, or gabled ceilings, try to mount
detectors 0.91 meter measured horizontally from the highest point of the ceiling
as shown Figure 6.

This alarm is only intended to be ceiling mounted or no more than 12
inches below the ceiling.
This alarm will only indicate the presence of carbon monoxide gas at
the sensor. Carbon monoxide gas may be present in other areas.
The user shall actuate the test and/ or alarm reset/silence feature
remotely (via an electronic signal or aerosol test gas), or by use of a person’s
finger or thumb, and that the use of any other instrument(s) is strictly prohibited.

CAUTION
(As required by the California State Fire Marshall)
“Early warning fire detection is best achieved by the installation of fire detection
equipment in all rooms and areas of the household as follows: (1) A smoke
detector installed in each separate sleeping area (in the vicinity, but outside of the
bedrooms), and (2) Heat or smoke detectors in the living rooms, dining rooms,
bedrooms, kitchens, hallways, attics, furnace rooms, closets, utility and, storage
rooms, basements and attached garages.”
“For your information, the National Fire Alarm and Signaling Code, NFPA 72, reads
as follows:”
“29.5.1 *Required Detection.”
*29.5.1.1 Where required by applicable laws, codes, or standards for a specific type
of occupancy, approved single- and multiple-station smoke alarms shall be
installed as follows:
(1) *In all sleeping rooms and guest rooms
(2) *Outside of each separate dwelling unit sleeping area, within 21 ft (6.4 m) of any
door to a sleeping room, the distance measured along a path of travel
(3) On every level of a dwelling unit, including basements
(4) On every level of a residential board and care occupancy (small facility),
including basements and excluding crawl spaces and unfinished attics
(5) *In the living area(s) of a guest suite
(6) In the living area(s) of a residential board and care occupancy

Locations not to install your detector
Nuisance alarms take place when smoke detectors are installed where they will
not work properly. To avoid nuisance alarms, do not install smoke detectors in the
following situations:
• Combustion particles are the by-products of something that is burning. Thus,
in or near areas where combustion particles are present you do not install the
smoke detectors to avoid nuisance alarms, such as kitchens with few windows
or poor ventilation, garages where there may be vehicle exhaust, near furnaces,
hot water heaters, and space heaters.
•
Do not install smoke detectors less than 20 feet (6 meters) away from places
where combustion particles are normally present, like kitchens. If a 20-foot
distance is not possible, e.g. in a mobile home, try to install the detector as far
away from the combustion particles as possible, preferably on the wall. To
prevent nuisance alarm alarms, provide good ventilation in such places.
•
When air streams passing by kitchens, the way how a detector can sense
combustion particles in normal air-flow paths is graphically shown in Figure 7,
which indicates the correct and incorrect smoke detector locations concerning
this problem.

WARNING! !
This product is intended for use in ordinary indoor locations of family living units. It
is not designed to measure compliance with Occupational Safety and Health
Administration (OSHA) commercial or industrial standards. OSHA has established
that continuous exposure levels of 50ppm should not be exceeded in an 8 hour
period. Individuals with a medical problem may consider using warning devices
which provide audible and visual signals for carbon monoxide concentrations
under 30ppm.

FOR SMOKE DETECTOR
Smoke detectors should be installed in accordance with the NFPA Standard 72
(National Fire Protection Association, Batterymarch Park, Quincy, MA 02169). For
complete coverage in residential units, smoke detectors should be installed in all
rooms, halls, storage areas, basements, and attics in each family living unit.
Minimum coverage is one detector on each floor and one in each sleeping area.
Here, we have useful tips for you:
•
Install one separate smoke detector in every bedroom and one smoke detector
in the floor as a minimum protection. Install one separate smoke detector in
every room, except kitchen and bathroom for more security, as shown in Figure
2 and Figure 3.
•
Install a smoke detector on every floor of a multi-floor home or apartment, as
shown in Figure 4.
•
Install a smoke detector inside every bedroom.
•
Install smoke detectors at both ends of a bedroom hallway if the hallway is
more than 40 feet (12 meters) long.
•
The detector is not to be located within 5 feet (1.5m) of any cooking appliance.
•
In damp or very humid areas, or near bathrooms with showers. Moisture in
humid air can enter the sensing chamber, then turns into droplets upon cooling,
which can cause nuisance alarms. Install smoke detectors at least 10 feet (3
meters) away from bathrooms.
In very cold or very hot areas, including unheated buildings or outdoor rooms.
If the temperature goes above or below the operating range of smoke detector,
it will not work properly. The temperature range for your smoke detector is 40
to 100 F (4.4 C to 37.8 C).
In very dusty or dirty areas, dirt and dust can build up on the detector’s sensing
chamber, to make it overly sensitive. Additionally, dust or dirt can block
openings to the sensing chamber and keep the detector from sensing smoke.
Near fresh air vents or very drafty areas like air conditioners, heaters or fans,
fresh air vents and drafts can drive smoke away from smoke detectors.
Dead air spaces are often at the top of a peaked roof, or in the corners between
ceilings and walls. Dead air may prevent smoke from reaching a detector. See
Figures 5 and 6 for recommended mounting locations.
In insect-infested areas. If insects enter a detector’s sensing chamber, they may
cause a nuisance alarm. Where bugs are a problem, get rid of them before
putting up a detector.
Near fluorescent lights, electrical “noise” from fluorescent lights may cause
nuisance alarms. Install smoke detectors at least 5 feet (1.5 meters) from such
lights.
Your smoke detector is not to be used with smoke alarm guards.
