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, NFPA Standard 74, Section 2-4 reads as follows:
“
2-4.1.1 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.
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 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, bedroom(s), kitchen, attic (finished or unfinished), furnace
rooms, utility room, basement, integral or attached garage, and hallways not
included in 2-4.1.1 above. However, the use of additional detectors remains
the option of the householder.”
We recommend complete coverage and use
of additional smoke detectors.
LOCATIONS TO INSTALL YOUR SMOKE DETECTORS
IN MOBILE HOMES AND RVs
Mobile homes and RVs built after about 1978 were designed and insulated to
be energy-efficient. In mobile homes and RVs built after 1978, smoke
detectors should be installed as described above. Older mobile homes and
RVs may have little or no insulation compared to current standards. Outside
walls and roofs are often made of non-insulated metal, which can transfer
thermal energy flow 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 smoke from reaching a smoke detector. Thereby, install smoke
detectors in such units only on inside walls. Place them between 4 and 6
inches (10 ~ 15 cm) from the ceiling. If you are not sure how much insulation
is in your mobile home or RV, then install the detector on an inside wall. If the
walls or ceiling are unusually hot or cold, then install the detector on an inside
wall. Install one detector as close to the sleeping area as possible for
minimum security, or install one detector in each room for security. Before you
install any detector, please read the following section on “LOCATIONS NOT
TO INSTALL YOUR SMOKE DETECTORS”.
LOCATIONS NOT TO INSTALL YOUR SMOKE
DETECTORS
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.
IMPORTANT:
For any reason, do not disable the detector to avoid
nuisance alarms.
˙
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
6, which indicates the correct and incorrect smoke detector locations
concerning this problem.

˙
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 32
o
F to 120
o
F (0
o
C to 50
o
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 4 and 5 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.
WARNING:
Never remove batteries to stop a nuisance alarm. Open a window
or fan the air around the detector to get rid of the smoke. The alarm will turn
itself off when the smoke is gone. If nuisance alarms persist, attempt to clean
the detector as described in this User’s Manual.
WARNING:
Do not stand close to the detector when the alarm is sounding.
The alarm is loud in order to wake you in an emergency. Too much exposure
to the horn at close range may be harmful to your hearing.
INSTALLING YOUR SMOKE DETECTOR
Model SD-218 series smoke detectors are to be mounted on the ceiling or on
the wall if necessary. Since SD-218 series smoke detector is a single-station
type, it cannot be linked to other detectors. Model SD-218 series with I mark
can serve as a single-station, stand-alone unit, or can be interconnected with
other SD-218 series with I mark detectors. (See “HOW TO CONNECT
SD-218*-I DETECTORS TOGETHER.”)
WARNING:
Do not connect the SD-218 series smoke detectors to any other
alarm or auxiliary device. Connecting anything else to this detector will keep it
from working properly.
Read “LOCATIONS TO INSTALL YOUR SMOKE DETECTORS” and
“LOCATIONS NOT TO INSTALL YOUR SMOKE DETECTORS” section in
this Manual first, then decide where to install a detector.
IMPORTANT: For the AC powered model- To avoid the electrical shock
hazard, turn off power to the area where you plan to install the
detector at the fuse box or circuit breaker box
Please follow these steps to install your smoke detector:
1. At the place where you are going to install the detector, draw a horizontal
line six inches long.
2. Remove the mounting bracket from your unit by rotating it
counterclockwise.
3. Place the bracket so that the two longest hole slots are aligned on the line.
In each of keyhole slots, draw a mark to locate a mounting plug and screw.
4. Remove the bracket.
5. Using a 3/16-inch (5mm) drill bit, drills two holes at the marks and insert
plastic wall plugs. Put the detector away from getting plaster dust on it
when you drill holes for mounting.
6. Using the two screws and plastic wall plugs (all supplied), attach the
bracket to the wall.
NOTE
:
If this detector is to be connected to other detectors, read the
instructions in the Section of “How to Interconnected Model with -I Series
Detector Together” before you finish installing the detector. If the detector
is not for interconnection purpose, do not use the “INTERCONNCT” wire.
For AC powered model, please read the message as following:
A power connector with
brown
,
orange (for interconnection model)
,
and
blue
wires is packed with each detector. Use wire nuts to connect
these wires to the AC power supply. Connect the
brown
wire on the
connector to the
brown
AC power supply. Connect the
blue
wire on the
connector to the
blue
AC wire. While the
orange
wire is used for
INTERCONNCT mode only. And the
red
wire is used for 9Vdc output
only.

Plug the power connector into other connector attached at the back of the
detector as shown in Figure 7. It is keyed so it can only be installed one
way. Tug the connector to be sure that it is plugged in correctly. The
connector can be removed at any time by holding the connector body
firmly and pulling it out.
