WARNING

DO NOT INSTALL THE ACTUAL
SMOKE ALARM IN NEW OR
RENOVATED BUILDINGS UNTIL ALL
WORK IS COMPLETED (INCLUDING
FLOOR COVERINGS) AND
BUILDING HAS BEEN FULLY
CLEANED

1. READ THIS FIRST

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

• Open the unit and slide the switch as indicated. This

will connect the battery permanently. Press the test
button and the horn should sound.

• When the battery is first connected the Alarm may sound
for 2-3 seconds and/or the red light may flash quickly for
10 seconds - this is normal.

2.1 Single Storey Dwelling.
If your Home is on one level (a bungalow or mobile home for
example) you should put your 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 you in the bedroom. (for exam­ple, see figure 1)
If your bungalow is very large and the corridor or hallway is
more than say 20 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.

Figure 3: Multi Storey Dwelling

(Excessive dust & debris from building work can
contaminate the smoke chamber and cause
problems).

An installed smoke alarm must be removed or
covered fully (with a plastic bag or similar)
before renovations begin.

& HUSH)

• A Smoke Alarm does not prevent fires.

• Install correctly, in the centre of the ceiling if possible.

• Test weekly.

• If the Alarm beeps without

the red light flashing at the
same time then clean unit as this is the automatic test fea­ture telling you the chamber is degraded.

• Plan your escape route.

• Proper protection may require more than one Smoke
Alarm.

• If you have any doubt or query about Smoke Alarms con­sult the supplier or your local Fire Brigade.

• When the Alarm beeps and

the red light flashes at the
same time it indicates the battery is depleted and the entire
alarm must be replaced. This normally occurs when over
10 years has elapsed.

2. LOCATING YOUR SMOKE ALARM

Sufficient smoke must enter your 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
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.
Y

our 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.

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).

2.2 Multi Storey Dwellings
If your home has more than one floor, at least one alarm
should be fitted on each level (see figure 3). It is recommend­ed that the alarms should be interconnected for best protec­tion.

2.3 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 the locations to avoid, mentioned below). 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.

2.4 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 you.
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.
The Interconnect Smoke Alarms Ei3105TYC and
Ei3105TYCH are designed for this - when one alarm senses
smoke, all connected alarms respond.

3. POSITIONING YOUR SMOKE ALARM

3.1. 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
ed away from corners. Place the unit at least 0.3m (1ft) from
any light fitting or decorative object which might obstruct
smoke entering the Smoke Alarm. Keep at least 0.3m (1ft)
away from walls and corners. See figure 4.

3.2 Wall Mounting
When a ceiling position is not practical (for example on a ceil­ing having exposed beams or joists, or built-in radiant heat­ing) put the top edge of your Smoke Alarm between 15 and
30 cm (6 and 12 inches) below the ceiling. Keep at least 0.3m
(1ft) from corners. (see figure 4).

3.3 On a sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke
Alarm 0.9m from the highest point measured horizontally (see
figure 5), because “dead air” at the apex may prevent smoke
from reaching the unit.

3.4 Locations to Avoid
Don’t place your Smoke Alarm in any of the following areas:

• Bathrooms, kitchen, shower rooms, garages or other
rooms where the smoke alarm may be triggered by steam,
condensation, normal smoke or fumes.

• Attics or other places where extremes of temperature may
occur (below 4°C or above 40°C).

• Near a decorative object, door, light fitting, window
molding etc., that may prevent smoke from entering the
Smoke Alarm.

• Surfaces that are normally warmer or colder than the rest
of the room (for example attic hatches, uninsulated exteri­or walls etc). Temperature differences might stop smoke

Alarms must be mount-

from reaching the unit.

• Next to or directly above heaters or air conditioning
vents, windows, wall vents etc. that can change the
direction of airflow.

• In very high or awkward areas where it may be difficult to
reach the alarm (for testing, etc).

• Locate unit at least 1.5m and route the interconnect wiring
at least 1m away from fluorescent light fittings as elec­tricial “noise” and/or flickering may affect the unit.

• Locate away from very dusty or dirty areas as dust build­up in the chamber can make unit too sensitive and prone
to alarm. It can also block the insect screen mesh and pre­vent smoke from entering the chamber.

• Do not locate in insect infested areas. Small insects get-
ting in to the chamber can cause intermittent alarms.

3.5 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 house 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 re-locate the device away from the source of the
fumes.

Fanning vigorously with a newspaper or similar will help
silence alarm.

The Smoke Alarms with the Hush feature Ei3105TYH &
Ei3105TYCH are designed for more difficult areas as press­ing the test button also silences the alarm for about 10 min­utes (see page 8 for details).

4. INSTALLING YOUR SMOKE ALARM

4.1 Attaching to Ceiling or Wall.

(NB: For Interconnecting see page 11)
The Smoke Alarm is battery operated and needs only wiring,
if the Interconnect facility is being used.

1. Pull cover open at tab. Remove cover from base by sepa-

rating at rear snap-in hinges by rotating cover backwards.

3

2. Place the base on ceiling / wall exactly where you want to
mount the unit. With a pencil, mark the location of the two
screw holes.

Figure 6

3. SLIDE SWITCH
TO CON NECT
BATTERY

3. Taking care to avoid any electrical wiring in the ceiling, drill
holes through the centres of the marked locations. Push the
plastic screw anchors provided into the drilled holes. Screw in
firmly.

4.2 Connecting the built-in Lithium Battery

Slide black switch in direction indicated. This connects the
built-in Lithium Battery permanently.

5. LOOKING AFTER YOUR SMOKE ALARM

5.1 Automatic Self-Test

The smoke chamber automatically tests itself every 40 sec­onds. If the chamber is degraded it will beep without the red
light flashing at the same time. If this happens clean the unit.
If the beeping persists and the beep does not coincide with an
red light flash, return the unit for service (see “Getting your
Smoke Alarm Serviced”)

5.2 Manually Testing your Smoke Alarm

It is recommended that you test your Smoke Alarm at least
once a month to be sure the unit is working. It will also help
you and your family to become familiar with the sound of the
Alarm.

When you press the test button it simu­lates the effect of smoke during a real
fire. So, there is no need to test the
Alarm with smoke.

Press and hold the Test Button until the
alarm sounds (it may take up to 10 sec­onds), (Figure 7). The alarm will stop
sounding shortly after the button is
released. If the alarm fails to sound, fol­low this checklist. Check the age of the
unit - see “replace by” label on base of
unit.

Ensure battery connection switch shown in figure 6 has been
slid fully in direction indicated.

Check for any sign of contamination such as cobwebs or dust
and clean the alarm as described on page 9 if necessary.

WARNING: Do not test with flame.
This can set fire to the alarm and damage the house. We do
not recommend testing with smoke as the results can be mis­leading unless special apparatus is used.

5.3 Power Indicator Light.

The Smoke Alarm has a Power Indicator Light which flashes
once a minute through the test button to show the Smoke
Alarm is powered.Check regularly. Replace the Smoke Alarm
if the flashing stops.

5.4 Smoke Alarms with Hush feature (Ei3105TYH/TYCH)

Some models have a silencer feature to help you control

Figure 7

5 6 7 8

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
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.

If kitchen usage/layout is such that there are an unacceptable
level of nuisance alarms, re-locate the Smoke Alarm further
away where it will be less affected by cooking fumes etc.

5.5 Cleaning your Smoke Alarm

Clean your Smoke Alarm regularly. Use a soft bristle brush or
the brush attachment of your vacuum cleaner to remove dust
and cobwebs from the sides and cover slots where the smoke
enters. Keep cover closed while cleaning. Do not vacuum or
brush inside the Smoke Alarm. To clean the cover, remove it
completely and use only mild soap and water. Dry cover thor­oughly before replacing it.

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 all servic­ing work.
If you experience persistent false alarms, in particular loca­tions, due to contamination of the smoke chamber you could
consider fitting our ionisation type Smoke Alarm. The principle
of ionisation detection makes it less vulnerable to the effects
of dust or insect contamination.

5.7 End of life

The entire Smoke Alarm must be replaced if:-

(i) The unit is installed for over 10 years (check the replace­ment year marked on the unit).

(ii) The unit is giving a short beep every 40 seconds and the
red light flashes at the same time for over 1 hour. (If the unit
beeps without the red light flashing at the same time see
”Cleaning your Smoke Alarm” above).

(iii) The unit fails to sound the horn loudly when the test button
is pressed.

Before the Smoke Alarm is discarded, cut “end of life” red wire
shown in figure 8 with a scissors to stop the low battery beeps
or the possibility of the unit alarming. Perforate the label to
access wire. Do not put the Smoke Alarm

Figure 8

into a fire.

6. INTERCONNECTING YOUR SMOKE ALARM

A maximum of 12 Ei 3105TYC/TYCH or Ei 100TYC Smoke
Alarms may be wired together such that when one unit sens­es smoke all other units sound a warning. This helps ensure
smoke alarms will be heard. Do not connect to any other
device as it may damage the unit or affect performance.
A maximum of 250 metres (820ft) of signal cable can be used,
(maximum resistance between detectors 50 ohm). The units
are interconnected by wiring all the terminals marked 1
together, and all the terminals marked 2 together (as in figure

9) before screwing to ceiling. Draughts, through the ceiling,
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 including the wiring
hole (see figure 9) be closed by silicone sealant or similar.

After wiring together the Interconnect Smoke Alarms, test the
first unit by pressing the button. All the detectors should alarm
and the test button on the first unit will flash about once a sec­ond. Please note it can take up to 5 seconds for some of the
interconnected units to sound. Check all the other units simi­larly.
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. Everybody may not be aware that they are being test­ed or that it is a nuisance alarm caused by cooking etc.

Figure 9

• Please read all instructions.

• Rehearse emergency escape plans so everyone at home
knows what to do in case the alarm sounds.

• Constant exposure to high or freezing temperatures, high
humidity or a high level of nuisance alarms may reduce the
life of the battery.

• Nuisance alarms can be quickly silenced by fanning vigor­ously with a newspaper or similar to remove the smoke.
On units with the hush feature (Ei3105TYH, Ei3105
TYCH) press the test button.

• Do not attempt to remove, recharge or burn battery, as it
may explode.

• If it is necessary to remove the battery for separate dis­posal, handle carefully to avoid possible eye damage or
skin irritation if battery has leaked or corroded.

• To maintain sensitivity to smoke, do not paint or cover
smoke alarm in any manner; do not permit any accumula­tion of cobwebs, dust or grease.

• If unit has been damaged in any way or does not function
properly,do not attempt a repair. Return Smoke Alarm (see

- Getting your Smoke Alarm Serviced page 15.)

•

This appliance is intended ONLY for premises having a
residential type environment.

• This is not a portable product. It must be mounted follow­ing the instructions in this instruction leaflet.

• Smoke Alarms are not a substitute for insurance. The sup­plier or manufacturer is not your insurer.

5.6 Dust & Insect Contamination

All Smoke Alarms and particularly the optical (photoelectric)
type are prone to dust and insect ingress which can cause
false alarms.
The latest design, materials and manufacturing techniques
have been used in the construction of our Alarms to minimize
the effects of contamination. However it is impossible to com­pletely eliminate the effect of dust and insect contamination,
and therefore, to prolong the life of the Smoke 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.
In certain circumstances even with regular cleaning, contam­ination can build up in the smoke sensing chamber causing
the alarm to sound. If this happens the alarm must be

9 10 11 12

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 improve the
probability of early detection.

• The Smoke Alarm may not be heard.

• A smoke alarm may not wake a person who has taken
drugs or alcohol.

• Smoke Alarms may not detect every type of fire to give suf­ficient early warning. They are particularly ineffective with:
fires caused by smoking in bed, escaping gas, violent
explosions. poor storage of flammable rags and/or liquids,
(for example petrol, paint, spirits etc), overloaded electrical
circuits, arson, children playing with matches.

• Smoke Alarms don’t last indefinitely. The manufacturer
recommends replacement after 10 years as a precaution

• Use the Smoke Alarm Test Button to familiarize your fami­ly with the Alarm sound and to practice fire drills regularly
with all family members. 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.

PLANNING YOUR ESCAPE ROUTE FOR

WHEN THE ALARM GOES OFF

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.

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.

8.2 FIRE SAFETY HINTS

Store petrol and other flammable materials in proper contain­ers.

Discard oily or flammable rags.

Always use a metal fireplace screen and have chimneys
cleaned regularly.

Replace worn or damaged sockets, switches, home wiring and
cracked or frayed electrical cords and plugs.

Do not overload electrical circuits.

Keep matches 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.
Be sure all electrical appliances and tools have a recognised
approval label.

This device cannot protect all persons at all times. It may not
protect against the three most common causes of fatal fires:

1. Smoking in bed.

2. Leaving children at home alone.

3. Cleaning with flammable liquids, such as petrol.

Further information can be obtained from the Fire Brigade.

WHAT IS THE BEST SMOKE ALARM -

OPTICAL OR IONISATION ?

Both types respond in all standard fires but each type may
respond faster to particular fires as shown. Ei Electronics man­ufactures two complementary 10 Year Smoke Alarms, Optical
Smoke Alarm Ei 105TYC, Ei 3105TYC and Ionisation Smoke

7. IMPORTANT SAFEGUARDS

When using household protective devices, basic safety pre­cautions should always be followed, including those listed
below

Alarm Ei 100TYC with built-in Lithium battery. For dual

pro-

tection install each type.

The Home Office states (in FB2):

Optical Sensor

Best for slow smouldering fires

- large smoke particles

Ion Sensor

Best for fast flaming fires

- small smoke particles

“If your home has more than one floor, at least one alarm
should be fitted on each level. In this case a combination of
Optical and Ionisation alarms, preferably interconnected, will
give the best protection.

7.2 Limitations of Smoke Alarms

Smoke Alarms have significantly helped to reduce the number
of fire fatalities in countries where they are widely installed.
However independent authorities have stated that they may
be ineffective in some circumstances. There are a number of
reasons for this:

• Smoke Alarms will not work if the batteries are depleted or
if they are not connected. Test regularly and replace the
entire unit when it fails to operate.

• Smoke Alarms will not detect fire if sufficient smoke does
not reach the alarm. 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,
