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.

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.

B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:50 AM Page 2

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).

B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:50 AM Page 3

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.

B14464-R3-100TY-U&C-ENG.qxd 14/3/04 6:50 AM Page 4

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.

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.

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.

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.

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

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.
