WIRELESS SUPERVISED

PHOTOELECTRIC SMOKE DETECTOR

DÉTECTEUR DE FUMÉE PHOTOÉLECTRIQUE SUPERVISÉ

SANS FILS

Model: EL-2703

INSTALLATION INSTRUCTIONS

GENERAL DESCRIPTION

Electronics Line's smoke detector is single station, photoelectric smoke detector
with a built-in supervised wireless transmitter.
When sufficient smoke is detected, or the test feature is operated, the detector will
sound its alarm horn and the transmitter will send an ALARM message. The Alarm
output in the receiver will remain activated until the alarm condition clears.
The smoke alarm base lock discourages unauthorized removal of the smoke alarm
by requiring a screwdriver to remove the alarm from the base.
The smoke alarm provides the following signals to the control panel:

♦ Alarm
♦ Alarm restore
♦ Low battery
♦ Tamper
♦ Supervision

WARNINGS:

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 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.
This detector is not 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. 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”.

SELECTING A LOCATION

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 and
attics in each family living unit. Minimum coverage is one detector on each floor and
one in each sleeping area.

♦ 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 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.

Where 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 “Where not to install your
smoke detectors”.

Where Not to Install Your Smoke Detectors

False alarms occur when smoke detectors are installed where they will not work
properly. To avoid false alarms, do not install smoke detectors in the following
situations:
♦ Combustion particles are by-products of something burning. Do not install

smoke detectors in or near areas where combustion particles are present,
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 6 meters (20 feet) 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 false alarms, provide good ventilation in such places.

IMPORTANT:

Never try to avoid false alarms by disabling the detector.

♦ Do not mount smoke detectors in the path of fresh air intake. The flow of fresh

♦ Near paint thinner fumes.
♦ In close proximity to an automobile exhaust pipe; this will damage the detector.
♦ In damp or very humid areas or near bathrooms with showers. Moisture in

air in and out can drive smoke away from the smoke detector; thus reducing its
efficiency. Figure 6 indicates the correct and incorrect locations concerning
this problem.

humid air can enter the sensing chamber, then turns into droplets upon
cooling, which can cause false alarms. Install smoke detectors at least 3
meters (10 feet) away from bathrooms.
