1. Basic Information about your Smoke Alarm
A Smoke Alarm is an early warning device. Used correctly it
can give you and your family valuable extra time to escape.
Push the power-on button (inside the cover) until it clicks to
connect the battery permanently. Close the cover and press the
test button - horn should sound. Note: Battery cannot be
disconnected using the power on button.
• A Smoke Alarm does not prevent fires.
• Install correctly, in the centre of the ceiling if possible.
• Test weekly.
• 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.
• Nuisance alarms can be quickly silenced for 8 minutes by
pressing the hush button on the cover.
• The complete smoke alarm must be replaced by the year
marked on the unit.
• The complete Smoke Alarm must also be replaced if it beeps
every 40 seconds for over an hour as this indicates the
battery is depleted. Cut the “end of life” red wire before
discarding, to stop beeps.
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/25 feet) 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.
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) 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.
2
B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:50 AM Page 1

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).
(b) Multi Storey Dwellings
Multi storey dwellings should have a smoke alarm at each level
(see figure 3). The best place for your first Smoke Alarm is in
the downstairs hallway near the stairs. 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.

(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 the locations to avoid, mentioned on page 5). 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 should 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.
(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 you.
If a Smoke Alarm is too far away for it to wake you, it is best to
link it to another Smoke Alarm near the bedroom. The model Ei
100TYC Smoke Alarms can be interconnected so when one
alarm senses smoke, all connected alarms respond. (see page
6 for further details).
3. Positioning your Smoke Alarm
(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 300mm (12 inches) from any
light fitting or decorative object which might obstruct smoke
entering the Smoke Alarm. Keep at least 300 mm (12 inches)
away from walls and corners. (See figure 4).
(b) 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 150 and 300mm (6
and 12 inches) below the ceiling. Keep at least 300mm (12
inches) from corners. (See figure 4).
4
B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:50 AM Page 3

(c) On a sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke
Alarm 900mm (3ft) from the highest point measured
horizontally (see figure 5), because “dead air” at the apex may
prevent smoke from reaching the unit.
(d) 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 metre
(20 ft) away from sources of nuisance alarms - wall mounting
if necessary.
• Attics or other places where extremes of temperature may
occur (below 4°C/34°F or above 40°C/104°F).
• 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 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 (5 feet) and route wiring at least 1m
(3 feet) away from fluorescent light fittings as electrical
“noise” and/or flickering may affect the unit.
• Locate the unit at least 1 metre (3ft) from dimmer controlled
lights and wiring - some dimmers can cause interference.
• Locate away from very dusty or dirty areas as dust build-up
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 getting
in to the chamber can cause intermittent alarms.
(e) 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.

This Smoke Alarm is designed for more difficult areas, as you
can silence the alarm for 8 minutes. This gives time for smoke
or fumes to clear, (see page 8 for more details).
4. Installing your Smoke Alarm
(a) Attaching to Ceiling or Wall
(NB details of how to interconnect the Smoke Alarm Ei100TYC
are given on page 7).
The Smoke Alarm is battery operated and needs no wiring,
(except when interconnecting). Use figure 6 below, as a help in
mounting.
1. Pull Cover open at Tab (2). Remove Cover from Base by
separating at rear Snap-in Hinges (5).
2. Place the Base on ceiling or wall exactly where you want to
mount the unit. With a pencil, mark the location of the Screw
Holes (6).
3. Taking care to avoid any electrical wiring in the ceiling or wall,
B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:51 AM Page 5

drill a hole through the centers of the marked locations. Push
the plastic Screw Anchors provided into the drilled holes. Screw
in firmly.
(b) Connecting the built-in Lithium battery
Push the power-on button (8), (see figure 6) until it clicks to
connect the battery permanently. Note: You may hear a loud
chirp when pressing the button. This is normal.
To close the cover match up the snap-in hinges (5) and gently
press together until they are attached. Press the test button (3)
- the horn should sound to show the Smoke Alarm is now
working. If the horn does not sound try pushing the power-on
button (8) again. Note: The power-on button cannot be used to
disconnect the battery.
5. Interconnecting your Smoke Alarm
A maximum of twelve Ei100TYC 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. (Model Ei100TY & Ei100TYK can not be
interconnected).
The Ei100TYC Ionisation Smoke Alarm may also be
interconnected to the Ei Optical Smoke Alarm, model number
Ei3105TYC.
Warning: Do not interconnect to any other Smoke Alarms
A maximum of 250 metres (820 feet) of wire 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 shown in
Figure 7. An opening should be made in the label covering the
wiring hole in the base, and the wires routed into the unit as
shown. Note that the wiring inside the unit must be kept clear of
the test button contacts, but must not impede the air flow.
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 are
sealed 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
within about 5 seconds. Check all the other units similarly.
7
B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:51 AM Page 6

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.
Indicator light
When interconnected units are in alarm the fast flashing red
light behind the test button indicates the unit initiating the
alarm. To silence a nuisance alarm, the hush button on the unit
with the fast flashing red light must be pushed. (Pressing the
hush button on any of the other units will not silence the alarm.)
6. Looking after your Smoke Alarm
(a) Testing your Smoke Alarm
It is recommended that you test your Smoke Alarm once a
week to be sure the unit is working. It will also help you and
your family to become familiar with the sound of the Alarm.
Press and hold the test button until
the Alarm sounds (it may take up to
10 seconds), (Figure 8). The Alarm
will stop sounding shortly after the
button is released. If the Alarm fails
to sound, follow this checklist.
1. Press the power on button to
connect the battery permanently.
2. Check the cover is correctly
snapped on to its hinge and that it is
fully closed.
3. Refer to “Cleaning Your Smoke
Alarm” 6 (c) on page 9.
WARNING: Do not test with flame.
This can set fire to your Smoke Alarm and damage your house.
We do not recommend testing with smoke as the results can be
misleading unless special apparatus is used. Pressing the test
button simulates the effect of smoke during a real fire and is the
best way to ensure the Smoke Alarm is operating correctly.
Power Indicator Light
Some Smoke Alarms (models Ei100TY and Ei100TYC) have 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. (This
does not apply to the Ei100TYK model).
(b) Hush Button
This model has a special false Alarm silencer feature to help
you control nuisance false alarms.
1. To cancel a false Alarm, press the Hush Button located on the
lower right-hand corner. The Alarm will automatically switch to a
reduced sensitivity condition. This condition allows unwanted
alarms to be silenced for a period of approximately 8 minutes.
8
B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:51 AM Page 7

2. The unit will reset to normal sensitivity at the end of the
silenced period. If additional silenced time is required, simply
push the Hush Button again.
3. To quickly return to normal non-silenced operation, simply
push the Test Button; the Alarm will sound briefly and return to
its normal, sensitive Alarm mode.
4. 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 where it
will be less affected by cooking fumes etc.
(c) 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.
WARNING: Do not paint your Smoke Alarm.
Other than 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.
(d) End of life
The entire Smoke Alarm must be replaced if:-
(i) The unit is installed for over 10 years (check the replace by
date marked on the side of the base).
(ii) The unit is giving a short beep every 40 seconds for over 1
hour.
(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 6a with a scissors to stop the low battery beeps
or the possibility of the unit alarming. Do not put the Smoke
Alarm into a fire.
We recommend that the unit is maintained (i.e. battery checked
and unit cleaned) as described above at least yearly.
7. Important Safeguards
When using household protective devices, basic safety
precautions should always be followed, including those listed
below:
• Please read all instructions.
• Rehearse emergency escape plans so everyone at home
knows what to do in case the Alarm sounds.
9
B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:51 AM Page 8

• NOTE: Constant exposure to high or freezing temperatures or
high humidity may reduce the life of the batteries.
• Do not cut the power lead to stop Alarm sounding as the
battery cannot be reconnected. (Pressing the Hush Button or
fanning vigorously with a newspaper or similar will remove
nuisance smoke from the Smoke Alarm and stop it
sounding.)
• Dispose of the complete Smoke Alarm including the batteries
inside. Do not attempt to recharge or burn the batteries, as
they may explode.
• 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.
• The black chamber located in the Smoke Alarm contains a
small amount of radioactive material (0.9 Microcuries
Americium 241). Do not tamper with the chamber. You may
safely install and clean the Smoke Alarm following
instructions in this leaflet.
• 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 13.)
• In the United Kingdom Ionisation Smoke Alarms can be
disposed of in normal household refuse, but due to the tiny
amount of radioactive material contained in the unit, no more
than one Alarm per dustbin.
• In the Republic of Ireland Ionisation Smoke Alarms should be
returned for disposal to the nearest address at the end of this
leaflet.
• This appliance is intended for residential type environments
only.
• 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.
(b) 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 up to 35% of all fires. 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 entire
Smoke Alarm when battery is depleted.
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, 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
10
B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:51 AM Page 9

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.
The Smoke Alarm must be replaced after 10 years operation.
The Smoke Alarm has been designed to operate for 10 years
and it is covered by a 5 year limited guarantee. The 10 year life
is based on accelerated testing, as the actual Smoke Alarm
has not been on test for 10 years. The batteries in this Alarm
cannot be replaced, and when the batteries are depleted, you
must replace the complete Smoke Alarm for continued
protection against fire.
8. Planning your Escape for when the Alarm
goes off
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 - see below.
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. Most
people die from smoke inhalation
rather 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.
