installed by a competent person and in
accordance with the current IEE Wiring
Regulations. If in doubt, consult a
qualified electrician.

effective at detecting flaming fires which
consume combustible materials
rapidly and spread quickly. Sources of these
fires may include paper burning in a waste
paper or rubbish bin or a grease fire in the

4. This alarm is designed to be used
inside a single family building only. In
multi-family buildings, each individual
living unit should have its own alarm.
DO NOT install in non-residential
buildings or places which house many
people like hotels, motels, dormitories,
hospitals, nursing homes or group
homes. This alarm is not a substitute
for a complete alarm system.
Note: For best protection, we recommend
that you install a smoke alarm in every
6. Smoke alarms may not alert every
household member every time. The
alarm sound of the alarm is loud in
order to alert individuals of a potential
danger. However, there may be limiting
circumstances where a household
member may not hear the alarm (i.e.
outdoor or indoor noise, sound sleepers,
the hard of hearing, etc.)
Typical Multi-Story or Split Level Home
Install a smoke alarm on the ceiling or
wall inside each bedroom and in the
hallway outside each separate sleeping
area. If a bedroom area hallway is more
than 30 feet long, install a smoke alarm
at each end. Also, install a smoke alarm
on the top of a first to second floor stairwell.
Typical Single-Story Home
Install a smoke alarm on the ceiling or
wall inside each bedroom and in the hallway
outside each separate sleeping area. If a
bedroom area hallway is more than 30

7. Household members must hear the
alarm’s warning sound and quickly
respond to it, to reduce the risk of
damage, injury or death that may
result from a fire. If a household
member is hard of hearing, install
special smoke alarms with lights or
vibrating devices to alert occupants.
8. Smoke alarms can only sound their
alarms when they detect smoke.
Smoke alarms detect combustion
particles in the air. They do not sense
heat, flames or gas. This smoke alarm
is designed to give audible warning of
a developing fire. However many fires
are fast-burning, explosive or intentional.
Others are caused by carelessness or
safety hazards. Smoke may not reach

to ensure safe escape.

1. Install a smoke alarm as close to the
center of the ceiling as possible. If this
is not practical, mount no closer than
4 inches from a wall or corner. Also, if
local codes allow, install smoke
alarms on the wall between 4 and 12
inches from the ceiling/wall

2. Install a minimum of two smoke
alarms in every home, no matter how
small the home.
PLEASE NOTE: The alarm will not
mount to the plate if the battery is not
installed. You must install the battery.
3. Install a smoke alarm in each room
that is divided by a partial wall either
coming down from the ceiling at least
8 inches, or coming up from the floor.
14.You can now turn the mains power
supply back on and test your alarm.
See the ‘Testing’ section.
4. Install a smoke alarm in lived-in attics
or attics which house electrical
equipment like fires, air conditioners or
2. Remove the mounting plate from the
back of the alarm by turning the plate
counter clockwise.
3. Gently pull the wires through the
centre hole of the plate.
4. Secure the plate to the ceiling or wall
with mounting screws.
5. With a three way connector block,

DO NOT INSTALL SMOKE ALARMS 1. Near appliances or areas where
normal combustion regularly occurs
such as kitchens, near fires or hot
water heaters.
2. In areas with high humidity, like
bathrooms or areas near dishwashers
or washing machines. Install at least
10 feet away from these areas.
3. Near air returns or heating and
cooling supply vents. Install at least 3
feet away from these areas. The air
could blow smoke away from the
detector, interrupting its alarm.
6. Connect the blue wire from the
connector plug to the blue/black
household wire.
8. Lift open the battery pocket door.
9. Connect the new 9V battery to the
battery connector inside the battery
pocket. Be sure that the battery is
securely connected. The alarm may
beep briefly when the battery is

WARNING: This alarm is mains powered
and requires wiring in accordance with
the current IEE Regulations for Electrical
Installations (BS7671).
The circuit used to power the smoke
alarm must be a dedicated permanent
supply that cannot be switched off
accidentally by the normal user. Before
installing ensure the electrical supply is
1. Isolate the power supply by switching
off at the mains.
For inter-connecting line, use only
1.0mm2 to 1.5mm2 solid or stranded
wire. When inter-connecting, the maximum wire length can be up to 1500 feet
between any two alarms using 1.0mm2 or
4000 feet for 1.5mm2. (20 Ohms loop
This alarm can be inter-connected with
as many as 40 KingShield smoke or heat
alarms. Do not try to connect to any
other type or model of alarm other than
KingShield models.
7. If you want to inter-connect more
alarms, connect the yellow wire from
the connector to the inter-connection
wire between the smoke alarms. See
‘Inter-Connecting Your Smoke Alarms’
If it is a single alarm you are installing,
simply cover the yellow wire with
electrical tape and tuck it into the
junction box.
4. Do not install smoke alarms in rooms
where temperatures may fall below
4°C or rise above 38°C.
12.Gently tug the connector to be sure it
is attached securely.
13.Position the alarm on the mounting
plate and turn clockwise to lock into
place. To engage the tamper resist
feature, insert the pin into the notch
on the edge of the alarm when the
alarm is properly positioned on the
mounting plate.
Once the alarm has been installed a
small green LED indicator light should
be visible through the alarm grill, indicating
that it is receiving AC supply. A red LED
indicator light should also flash once a
minute to indicate the battery is healthy
and the unit is operating properly.
If smoke is detected, the unit will emit a
loud pulsating alarm and a red indicator
light will flash quickly and will continue
to do so until the air is clear.
The ‘HUSH’ feature can mute the detector
if it has been advertently triggered by
holding down the ‘TEST/HUSH’ button
for a few seconds. The alarm will be
muted for 10 minutes and then will reset
into normal mode.

If the alarm sounds and you have not
pushed the test button, it is a warning of
a dangerous situation. Your immediate
response is necessary.
To prepare for such an occurrence,
develop family escape plans, discuss
them with all household members, and
practice them regularly.
1. Expose everyone to the sound of the
smoke alarm and explain what the
sound means.
2. Determine two exits from each room
and an escape route to the outside
from each exit.
3. Teach all household members to
touch the door and if it’s hot, they
must use an alternative exit. Instruct
them not to open the door if it is hot.
4. Teach household members to crawl
along the floor to stay below dangerous
smoke, fumes and gases.
5. Determine a safe meeting point for all
members outside the building.
1. Do not panic, stay clam.
2. Leave the building as quickly as possible.
Touch the doors to feel if they are hot
before opening them. Use an alternative
exit if the door is hot. Crawl along the
floor, do not stop to collect anything.
3. Meet at the pre-arranged meeting
point outside the building.
4. Call the fire brigade.
5. Do not go back inside a burning building.
Wait for the fire brigade to arrive.
These guidelines will assist you in the event
of a fire. However, to reduce the chance that
fires will start, practice fire safety rules and
prevent hazardous situations.
WARNING: DO NOT disconnect the
battery to stop an unwanted alarm. This
will stop your fire protection.
