INTRODUCTION
Everday’s single station photoelectric smoke detector is designed to sense
smoke that comes into the detector chamber. It does not sense gas, heat, 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 detector is located, installed, and maintained
properly as described in this User's Manual.
WARNING:
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
detectors 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 detectors.
WARNING:
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.
Please refer NFPA 101, the Life Safety Code, NFPA71, 72A, 72B, 72C, 72D,
and 72E for smoke detector requirements for fire protection in buildings not
defined as “households”.
WARNING:
strongly recommended that the special-purpose smoke detectors, using
lights or vibrating devices, should be installed to alert occupants who are
hard of hearing.

LOCATIONS TO INSTALL YOUR SMOKE DETECTOR
Smoke detectors should be installed in accordance with the NFPA Standard
74 (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 good tips for you:
• Install a smoke detector in the hallway outside every separate bedroom
area, as shown in Figure 1. Two detectors are required in homes with
two bedroom areas, as shown in 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 a smoke detector inside every room where one sleeps with the
door partly or completely closed, since smoke could be blocked by the
closed door and a hallway alarm may not wake up the sleeper if the
door is closed.

• 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 4
inches (10 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 codes, put wall-mounted detectors between 4 and
6 inches (10 ~ 15 cm) from the ceiling, also see 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.

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, 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 room, 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 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

• 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 power from a DC-power operated detector 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.
F to 100oF (4oC to 38oC).
INSTALLING YOUR SMOKE DETECTOR
This smoke detector is made to be mounted on the ceiling or on the wall if
necessary. Since this smoke detector is a single-station type, it cannot be
linked to other detectors.
WARNING: Do not connect this smoke detector 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, and then decide where to install a detector. 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 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, drill 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.
7. Line up the side slot of the bracket and the detector. Push the detector
onto the mounting bracket and turn it anti-clockwise to fix it into place.
Pull outward on the detector to make sure it is securely attached to the
mounting bracket.
