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.

Note:-

• When the battery is first connected the Alarm may sound

for 2-3 seconds - this is normal.

• A Smoke Alarm does not prevent fires.

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

• Test weekly.

• Replace battery yearly or when it beeps once a minute.

• 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 by fanning with a

newspaper or similar to help remove smoke from the unit.

Locating your Smoke Alarm

Sufficient smoke must enter your Smoke Alarm before it will

respond. Your Smoke Alarm needs to be within 10 paces (23

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 (seven 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 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.

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.

If your home is on more than one level you will require a

smoke alarm on each storey (see figure 3).

a fire on lower floors in sufficient time to ensure an adequate

escape.

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 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.

(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

Interconnect Smoke Alarm Ei100C is designed for this - when

one alarm senses smoke, all connected alarms respond. (see

page 9 for further details).

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 30cm from any light fitting

or decorative object which might obstruct smoke entering the

Smoke Alarm. Keep at least 15 cm away from walls and

corners. See figure 4.

Figure 4 Figure 5

10277-R12-9V-UC 29/9/09 7:49 AM Page 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 15

and 30 cm (6 and 12 inches) below the ceiling. Keep at least

15cm (6 inches) from corners. (see figure 4).

In areas with sloping or peaked ceilings install your Smoke

Alarm 90 cm (3 feet) 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

metres (20 feet) away from sources of smoke - 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

moulding 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, battery replacement etc).

(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.

The Silencer Smoke Alarm Ei100S 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 10 for more

details).

Installing your Smoke Alarm

(a) Attaching to Ceiling or Wall.

(NB: for wiring the Ei100C Interconnect model see page 9)

The Smoke Alarm is battery operated and needs no wiring,

(Ei100C excepted). 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, drill a hole through the centres of the marked locations.

Push the plastic Screw Anchors provided into-the drilled

holes. Screw in firmly.

(b) Connecting the battery.

With a pencil, write the date of Battery installation on the inside

of the Cover to remind you when to replace the battery (4).

Lift Battery from Battery holder, and snap Battery Connectors

to Battery. They fit together only one way (Figure 7).

Gently push Battery into Battery Holder (9)

To close the cover match up Snap-in Hinges (5) and gently

press together until Base and Cover snap together.

NOTE: You may hear a loud chirp when attaching the Battery

Connectors to the Battery. N.B. The emergency light Smoke

Alarm needs 2 batteries (see page 9 for details). Test the

installed Smoke Alarm - see section 5(a) below.

All models are fitted with a warning flag which pops up when

the battery is removed. This prevents the cover from closing

when there is no battery in the unit. When the battery is being

installed or changed, this flag must be held down while gently

pushing the Battery into the Battery Holder. (Figure 8).

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.

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

9). The alarm will stop sounding

shortly after the Button is

released. If the alarm fails to

sound, follow this checklist.

1. Check Battery Connectors to be sure they are firmly

snapped to the Battery.

2. Replace the Battery. (Check the date marked on the Cover

when you last replaced the Battery).

3. Refer to “Cleaning Your Smoke Alarm” (c) below.

WARNING: DO NOT TEST WITH FLAME.

This can set fire to the Alarm and damage the house.

We do not recommend testing with smoke or heat as the

results can be misleading unless special apparatus is used.

(b) Replacing the Battery(ies)

Test the alarm for correct operation using the test button

whenever the battery(ies) is/are replaced.

A fresh Battery should last about one year. When Battery

power is low and replacement is necessary, the Alarm will

“beep” about once per minute for at least 30 days. The battery

must then be replaced. Replace battery if the alarm does not

sound when the Test Button is pressed. For maximum

reliability, replace battery at least once a year.

On Smoke Alarms with a Power Indicator flashing light, if the

light ceases flashing replace the battery. Be sure to replace

the Battery as soon as possible to ensure proper operation

and to avoid a leaking Battery. Leakage could cause damage

to the Alarm, furniture, and carpeting.

For replacement batteries, refer to the information inside

Smoke Alarm Cover.

WARNING: Use of any other battery may be detrimental to

the operation of the Smoke Alarm.

Clean your Smoke Alarm regularly. Use a soft bristle brush or

the brush attachment of your vacuum cleaner to remove dust

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.

Smoke Alarms with Additional Features

A range of Smoke Alarms are produced which are optimized

for different locations and/or uses.

(a) Power Indicator Light.

A number of Smoke Alarms have a Power Indicator Light

which flashes once a minute through the test button to show

the Smoke Alarm is powered. Replace the battery if the

flashing stops.

(b) Emergency Light Smoke Alarm Ei100L

When the smoke alarm senses smoke, the bright emergency

light turns on to help identify and light the escape route. The

Smoke Alarm should therefore be located where it will light

the escape route - in a hallway, above a stairs or near the exit.

Connection and Replacement of Batteries.

The smoke alarm uses two different types of standard 9 volt

10277-R12-9V-UC 29/9/09 7:49 AM Page 8

batteries, an alkaline battery and a general purpose battery.

1. Connect an alkaline battery (use only Duracell MN1604 or

Eveready 522) to the blue battery connector to power the

light. This battery when fresh will normally last 1 year in the

stand by mode and provide over 15 minutes of light when in

alarm. The Smoke Alarm is normally shipped with the alkaline

battery connected to facilitate the customer - this does not

deplete the battery.

2. Connect the general purpose battery to the black battery

connector to power the smoke alarm. This battery when fresh

will normally last over one year before it needs replacement.

Replace both batteries when the smoke alarm gives a short

chirp every minute or when the light looks dim during a button

test.

Use only batteries specified on the Smoke Alarm, the use of

other batteries could have a detrimental effect on smoke

alarm operation or light output.

A maximum of 12 interconnect Ei100C or Ei105C 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.

Warning: Do not interconnect to any other Smoke Alarms.

A maximum of 250 metres (820ft) of 18 AWG (0.82mm) 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 10. 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 be closed by silicone sealant or similar.

You must press in and hold the test button for at least 4 to 5

seconds, as there is a time delay on some units.

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 every

2 seconds. Check all the other units similarly.

When interconnected units are in alarm, the red flashing light

indicates the unit sensing smoke.

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.

10277-R12-9V-UC 29/9/09 7:49 AM Page 9

(d) Silencer Smoke Alarm Ei100S

This model has a special false alarm silencer feature to help

you control nuisance false alarms.

1. To cancel a false alarm, press the Silencer 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.

2. The unit will reset to normal sensitivity at the end of the

silenced period. If additional silenced time is required, simply

push the Silencer 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 usage/layout is such that there are an unacceptable level of

nuisance alarms, even with the Silencer Smoke Alarm, re-

locate the Smoke Alarm farther away from the kitchen where

it will be less affected by cooking fumes.

Important Safeguards

When using household protective devices, basic safety

precautions should always be followed, including those listed

on next page.

•Please read all instructions.

•Rehearse emergency escape plans so everyone at home

knows what to do in case the alarm sounds.

•For replacement batteries, refer to the information inside

smoke alarm.

•NOTE: Constant exposure to high or freezing temperatures

or high humidity may reduce the life of the batteries.
