SD360EN-EI00 01/2016
Introduction
Paradox’s SD360 single station photoelectric smoke detector is designed to
sense smoke that comes into the alarm chamber. It does not sense gas, or
flame. This smoke detector is designed to give early warning of developing
fires by giving off the alarm sounds from its built-in alarm horn. It can provide
precious time for you and your family to escape before a fire spreads.
However, the smoke detector makes such pre-warning of fire accident
possible, only if the smoke detector is located, installed, and maintained
properly as described in this User Manual.
WARNING:
This smoke detector is designed for use in a single residential unit
only, which means that it should be used inside a single family home or
apartment. It is not meant to be used in lobbies, hallways, basements, or another
apartment in multi-family buildings, unless there are already working alarms in
each family unit. Smoke detectors, placed in common areas outside of the
individual living unit, such as on porches or in hallways, may not provide early
warning to residents. In multi-family buildings, each family living unit should set
up its own smoke detectors.
WARNING:
This detector is not meant to be used in non-residential buildings.
Warehouses, industrial or commercial buildings, and special purpose non-
residential buildings require special fire detection and alarm systems. This
detector alone is not a suitable substitute for complete fire detection systems for
places where many people live or work, such as hotels or motels. The same is true
of dormitories, hospitals, nursing homes or group homes of any kind, even if they
were once single family homes.
WARNING:
This detector will not alert people who are hard of hearing. It is
strongly recommended that the special-purpose smoke detectors using lights or
vibrating devices, should be installed to alert occupants who are hard of hearing.
Location to Install Your Smoke Detectors
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 a smoke detector in each separate room and exit way except
kitchen, as shown in Figure 1 and Figure 2.
• Install a smoke detector on every floor of a multi-floor home or
apartment, as shown in Figure 3
• Install a minimum of two detectors in any household
• 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
• 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 possi-
ble. 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 4
• If ceiling mounting is not possible and wall mounting is permitted by
your local and state regulations, put wall-mounted detectors
between 4 and 6 inches (10 ~ 15 cm) from the ceiling as shown in
Figure 4
• If some of your rooms have sloped, peaked, or gabled ceilings, try to
mount detectors 3 feet (0.9 meter) measured horizontally from the
highest point of the ceiling as shown in Figure 5
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 burn-
ing. Thus in or near areas where combustion particles are present you
do not install the smoke detector 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 kitch-
ens. 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 pos-
sible, preferably on the wall. To prevent nuisance 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 detector at least 10 feet (3 meters) away from bathrooms
• In very cold or very hot areas, including unheated buildings or out-
door 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 0~49ºC
• In very dusty or dirty areas, dirt and dust can build up on the detec-
tor’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
