2. LOCATING SMOKE ALARMS
Sufficient smoke must enter the Smoke Alarm before it will
respond. Your Smoke Alarm needs to be within 10 paces (7.5
metres) of the fire to respond quickly. It also needs to be in a
position where its alarm can be heard throughout your home,
so it can wake you and your family in time for you all to
escape. A single Smoke Alarm will give some protection if it is
properly installed, but most homes will require two or more to
ensure that a reliable early warning is given. For maximum
protection you should put individual Smoke Alarms in all the
rooms where fire is most likely to break out (except bathroom
and kitchen).
Your first Smoke Alarm should be located between the sleeping area and the most likely sources of fire (living room or
kitchen for example). But it should not be more than 10 paces
(7.5 metres) from the door to any room where a fire might start
and block your escape from the house.

A Smoke Alarm is an early warning device. Installing Smoke
Alarms can give you and your family valuable extra time to
escape.

a) Ceiling Mounting
Hot smoke rises and spreads out, so a central ceiling position
is the preferred location. The air is “dead” and does not move
in corners, therefore Smoke Alarms must be mounted away
from corners.
Place the unit at least 0.5 m from any light fitting or decorative
object which might obstruct smoke entering the Smoke Alarm.
Keep at least 0.5 m away from walls and corners. (see Figure
4)
• Locate away from very dusty or dirty areas as dust build-
Wall mounting is not recommended for Smoke Alarms.
b) Mounting on a Sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke
Alarm 90 cm from the highest point measured horizontally,
because “dead air” at the apex may prevent smoke from
reaching the unit.
c) Locations to Avoid
Don’t place your Smoke Alarm in any of the following areas:
• Bathrooms, kitchens, shower rooms, garages or other
rooms where the Smoke Alarm may be triggered by steam,
condensation, normal smoke or fumes. Keep at least 6 m
away from potential sources of fumes.
• Attics or other places where extremes of temperature may
occur (below 4oC or above 40oC).
• Near a decorative object, door, light fitting, window
moulding etc., that may prevent smoke from entering the
Smoke Alarm.
• Surfaces that are normally warmer or colder than the rest
If your bungalow is very large and the corridor or hallway is
more than say 22 paces (15 metres) long, one Smoke Alarm
will not be sufficient. This is because no matter where it is
located it will be more than 7.5 metres from potential fires.
c) Maximum Protection
For maximum protection you should put individual Smoke
Alarms in all the rooms where fire is most likely to break out,
(apart from kitchens, bathrooms etc., see “Locations to
Avoid”). The living room is the most likely place for a fire to
start at night, followed by the kitchen and then the dining
room. You should also consider putting Smoke Alarms in any
bedrooms where fires might occur, for instance, where there
is an electrical appliance such as an electric blanket or heater,
or where the occupant is a smoker. You could also consider
putting Smoke Alarms in any rooms where the occupant is
unable to respond very well to a fire starting in the room, such
as an elderly or sick person or a very young child.
If a Smoke Alarm is too far away for it to wake you, it is best
to interconnect it to another Smoke Alarm near the bedroom.
A maximum of twelve Smoke Alarms may be interconnected
(See page 1 for the model numbers of Smoke Alarms with
interconnect), so that all interconnected Alarms respond when
one Alarm senses smoke (see page 9 for further details).
3. POSITIONING YOUR SMOKE ALARM
Position your Smoke Alarm to comply with applicable building
regulations.
Figure 5
Figure 4
Ideal: Centre of the ceiling
In houses with more than one sleeping area, Smoke Alarms
should be placed between each sleeping area and the living
area. (For example, see Figure 2)

to alarm. It can also block the insect screen mesh and prevent smoke from entering the smoke detector chamber.
Figure 7a
• Do not locate in insect infested areas. Small insects getting into the smoke detector chamber can cause intermittent alarms.
d) Nuisance/False Alarms
If, when the Alarm goes off, there is no sign of smoke, heat or
noise to indicate that there is a fire, you should get your family into a safe place, before you start investigating.
Check the entire house/apartment carefully in case there is a
small fire smouldering somewhere.
Check whether there is some source of smoke or fumes, for
example cooking fumes being drawn past the Smoke Alarm
by an extractor.
If there are frequent nuisance/false Alarms it may be necessary to relocate the device away from the source of the fumes.
WARNING: Smoke Alarms do not function without a battery.

Fanning vigorously with a newspaper or similar will help
silence the Alarm by removing smoke from the sensing
chamber.
4. INSTALLING YOUR SMOKE ALARM

see page 9).
1. Pull cover open at tab. Do not remove the base from the
back of the Smoke Alarm.
of the room (for example attic hatches, uninsulated exterior walls etc). Temperature differences might stop smoke
from reaching the unit.
2. Find a suitable location, place the base of the Smoke Alarm
against the ceiling and mark the position of the screw holes
with a pencil.
• Next to or directly above heaters or air conditioning
3. Taking care to avoid any electrical wiring in the ceiling drill

vents, windows, wall vents etc. that can change the
direction of airflow.
a) Single Storey Dwelling
If the home is on one level (a bungalow or mobile home for
example) you should put the first Smoke Alarm in a corridor or
hallway between the sleeping and living areas. Place it as
near to the living area as possible, but make sure you can
hear it loudly enough to wake a person in the bedrooms. (See
Figure 1)
b) Multi Storey Dwellings
If your home is on more than one level the best place for your
first Smoke Alarm is in the downstairs hallway near the stairs.
(For example, see Figure 3). This is because smoke is likely

to be detectable in the hallway before it reaches the upstairs
landing and bedrooms. Your second Smoke Alarm should be
upstairs, because the downstairs Smoke Alarm is unlikely to
detect the smoke from a fire in a bedroom upstairs. We
strongly recommend that Smoke Alarms are fitted on each
story.
d) Checking you Can Hear your Smoke Alarm
With the Smoke Alarm sounding in its intended location,
check you are able to hear it in each bedroom with the door
closed, above the sound of your radio. The radio should be
set to a reasonably loud conversation level. If you can’t hear
it over your radio the chances are that it wouldn’t wake a person.

away from fluorescent light fittings as electrical “noise”
and/or flickering may affect the unit.
• Locate the unit at least 1 metre from dimmer controlled
lights and wiring - some dimmers can cause interference.

a) Automatic Self-Test
The smoke chamber automatically tests itself every 40 seconds. If the chamber is degraded the unit will beep, without
the LED flashing at the same time. If this happens clean the
unit.
b) Checking the Smoke Alarm
It is recommended that you test
your Smoke Alarm at least once a
week to be sure the unit is working properly. Press and hold the
Test Button until the Alarm
sounds (it may take up to 10 seconds), (see Figure 8). It will also
help you and your family to
become familiar with the sound of
the Alarm.
Figure 8
c) Replacing the Battery
Fresh batteries should last about one year. When the battery
is nearly depleted and needs to be replaced the unit beeps
once a minute for at least 30 days. The alarm will stop beeping when the battery has been replaced. Also replace the battery if pressing the test button does not cause the Alarm to
sound. For maximum reliability, replace the battery at least
once a year.
Insert the new battery as soon as possible to ensure proper
functioning of the unit. Leakage could cause damage to the
Alarm, furniture, and carpeting.
A flashing light every 40 seconds (without the unit beeping)
does not mean that the battery needs to be replaced.
c) Safety Lock
All models are fitted with a warning flag (safety interlock),
which pops up preventing the cover from being closed when
no battery is inserted. When inserting or replacing a battery
the flag must be pushed down into the battery holder.
Note: Also check proper functioning of the Smoke Alarm
after re-occupation following a holiday etc. by pressing
the test button.

For replacement batteries, refer to the label on the smoke
chamber.
WARNING: The use of other batteries could have a detrimental effect on the Smoke Alarm.
d) Cleaning your Smoke Alarm
Smoke Alarms are not excessively prone to dust and insect
ingress but should still be cleaned from time to time. Use the
narrow nozzle attachment of your vacuum cleaner to remove
dust, insects and cobwebs. To clean the cover, wipe with a
damp cloth.
WARNING: Do not paint your Alarm.
Apart from the maintenance and cleaning described in this
leaflet, no other customer servicing of this product is required.
Repairs, when needed, must be performed by the manufacturer.
WARNING: Do not connect EI Smoke Alarms to any
device apart from those listed on page 1 - this includes
units from other manufacturers.
A maximum of 250 m metres (820 ft) of wire can be used
(maximum resistance between detectors 50 ohms). The units
are interconnected by wiring all the terminals marked ‘1’
together, and all the terminals marked ‘2’ together as in Figure
9. Draughts from wiring openings, conduit, or mounting
boxes/holes, may blow smoke away from the sensing chamber, making it insensitive. It is essential that all such openings
be closed by silicone sealant or similar.
After wiring together the Interconnect Smoke Alarms, test the
first unit by pressing the button. All alarms should sound within 10 seconds. The red light should flash every second only
on the unit that is being tested. Check all the other units similarly.
6. SMOKE ALARMS WITH INTERCONNECT
A maximum of twelve Smoke Alarms may be interconnected
so that all Alarms respond when one Alarm senses smoke.
( For the model numbers of Smoke Alarms with Interconnect
see page 1). This ensures that the alarms will be heard everywhere within the building.

sible. Draw up a floor plan that will show each member at
least 2 escape routes from each room in the house. Children
tend to hide when they don’t know what to do. Teach children
how to escape, open windows, and use roll up fire ladders
and stools without adult help. Make sure they know what to do
if the Alarm goes off.
2. If smoke is heavy, crawl out,
staying close to floor. Take short
breaths, if possible, through a wet
cloth or hold your breath. More
people die from smoke inhalation
than from flames.
3. Get out as fast as you can. Do
not stop for packing. Have a prearranged meeting place outside for
all family members. Check
everybody is there.
4. Call the Fire Brigade from a
neighbour’s house. Remember to
give your name and address.
5. NEVER re-enter a burning
house.

8. IMPORTANT SAFEGUARDS
When using household protective devices, basic safety precautions should always be followed, including those listed
below:
7. HUSH FEATURE
These Smoke Alarms should be interconnected only within
the confines of a single family living unit. If they are connected between different units there may be excessive nuisance
alarms. Not everybody may be aware that the Alarm is being
tested or that it is a nuisance alarm caused by cooking etc.
Some models have a hush feature (see page 1) to help you
control nuisance/false alarms.
1. To cancel a false alarm, press the test button. The alarm
will automatically switch to a reduced sensitivity condition.
This condition allows unwanted alarms to be silenced for a
period of approximately 10 minutes. The red light will flash
every 10 seconds (instead of 40 seconds) to let you know the
unit has been silenced.
2. The unit will reset to normal sensitivity at the end of the
silenced period. If additional silenced time is required, simply

ly reduce the number of fire fatalities.
• However, independent authorities have stated that they
may be ineffective in some circumstances. There are a
number of reasons:
• Smoke Alarms will not work if the batteries are depleted or
if they are not connected properly, or if the wrong type of
battery is used. Test regularly and replace batteries at least
yearly or when depleted.
• Alarms will only detect fire if sufficient smoke or heat
Do not disconnect the battery to stop alarm sounding.
(Fanning vigorously with a newspaper or similar will remove
nuisance smoke from the Smoke Alarm and stop it sounding).

reaches the alarm’s sensors. Smoke may be prevented
from reaching the Alarm if the fire is too far away, for example, if the fire is on another floor, behind a closed door, in
a chimney, in a wall cavity, or if the prevailing air draughts
carry the smoke away.
• Installing Smoke Alarms on both sides of closed doors and
installing more than one Smoke Alarm as recommended in
this leaflet very significantly improves the probability of
early detection.
• The Alarm may not be heard.
Do not attempt to recharge or burn batteries, as they may
explode. Depleted batteries should be discarded properly.

explosions. poor storage of flammable rags and/or liquids,
(for example petrol, paint, spirits etc), overloaded electrical
circuits, arson, children playing with matches, for example.
• Smoke Alarms do not last indefinitely.
If the unit has been damaged in any way or does not function
properly, do not attempt a repair. Return Smoke Alarm to the
manufacturer (see “Getting your Smoke Alarm Serviced”,
page 14).
This appliance is intended for domestic household use only.
The manufacturer recommends a regular weekly check and
replacement of the unit after 10 years as a precaution.
9. PLANNING YOUR ESCAPE FOR WHEN
THE ALARM GOES
This is not a portable product. It must be permanently mounted following the instructions.
Use the Alarm test button to familiarise your family with the
Alarm sound and to practice fire drills regularly with all family
members to rehearse evacuating the building as fast as pos-
11
12
Do not overload electrical circuits.
Keep matches and lighters away from children.
Never smoke in bed. In rooms where you do smoke, always
check under cushions for smouldering cigarettes and ashes.
Service central heating systems regularly.
1. Check room doors for heat or
smoke. Do not open a hot door.
Use an alternate escape route.
Close doors behind you as you
leave.
If kitchen or bathroom usage/layout is such that there is an
unacceptable level of nuisance alarms, re-locate the Smoke
Alarm further away where it will be less affected by cooking
fumes, steam etc.
For replacement batteries, refer to the label inside the Smoke
Alarm.
In order to keep contamination to a minimum, the latest
design, up-to-date materials and methods are used in the production of this Alarm. However, it is impossible to completely
eliminate the effect of dust and insect contamination, and
therefore, to prolong the life of the Alarm you must ensure that
it is kept clean so that excess dust does not build up. Any
insects or cobwebs in the vicinity of the Smoke Alarm should
be promptly removed.
If there are frequent nuisance/false alarms in certain locations
you should consider moving the alarm.
Smoke Alarms are no substitute for insurance. The supplier or
manufacturer is not your insurer.
Rehearse emergency escape plans so everyone knows what
to do in case the alarm sounds.
Figure 9
All Smoke Alarms are prone to dust and insect ingress which
can cause false alarms or failure to alarm.
In certain circumstances even with regular cleaning, contamination can build up in the smoke sensing chamber causing
the alarm to sound or fail. If this happens the Alarm must be
returned to us for servicing or replacement. Contamination is
beyond our control, it is totally unpredictable and is considered normal wear and tear. For this reason, contamination is
not covered by the guarantee and a charge is made for servicing such units.
push the test button again.
3. If the cause of the alarm is not clear, it should be assumed
that it is due to an actual fire and the dwelling should be evacuated immediately.
Be sure all electrical appliances and tools have a recognised
approval label.
Contact the local authorities or the Fire Brigade for further
information.
