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 and/or the LED may flash quickly for 10 seconds

- this is normal.

• A Smoke Alarm does not prevent fires.

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

• Test monthly.

• When the Alarm beeps and LED flashes at the same time

replace battery.

• If the Alarm beeps without the LED 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.

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 twoor 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.

B10274-R4-105B-U&C-ENG 30/9/09 8:23 AM Page 2

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 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.

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.

(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 Alarms Ei105C and Ei100C are designed

for this - when one alarm senses smoke, all connected alarms

respond.

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 (12 inches) from any light

fitting or decorative object which might obstruct smoke entering

the Smoke Alarm. Keep at least 15 cm (6 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 15 and 30 cm (6

and 12 inches) below the ceiling. Keep at least 15cm (6 inches)

from corners. (see figure 4).

B10274-R4-105B-U&C-ENG 30/9/09 8:23 AM Page 3

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, 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/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, battery replacement etc).

• Locate unit at least 1.5m (5 feet) and route wiring at least 1m

(3 feet) 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 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.

B10274-R4-105B-U&C-ENG 30/9/09 8:23 AM Page 4

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.

Installing your Smoke Alarm

(a) Attaching to Ceiling or Wall

(NB: For Interconnecting see page 9)

The Smoke Alarm is battery operated and needs only wiring, if

the Inter-Link facility is being used.

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

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

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.

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.

B10274-R4-105B-U&C-ENG 30/9/09 8:23 AM Page 5

(b) Connecting the battery

The battery is easily removed from the holder by holding back

one of the plastic clips while lifting the battery with the other

hand.

Snap Battery Connectors to Battery. They fit together only one

way.

Gently push Battery into Battery Holder

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

of the cover to remind you when to replace the battery.

To close the cover match up snap-in hinges and gently press

together until base and cover snap together. Test the installed

Smoke Alarm - see section “Manually Testing your Smoke

Alarm”.

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

Connectors to the Battery.

Battery Missing indicator

Some 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 7(a)).

Looking after your Smoke Alarm

(a) Automatic Self-Test

The smoke chamber automatically tests itself every 40

seconds. If the chamber is degraded it will beep without the

LED flashing at the same time. If this happens clean the unit. If

the beeping persists and the beep does not coincide with an

LED flash, return the unit for service (see “Getting your Smoke

Alarm Serviced”).

B10274-R4-105B-U&C-ENG 30/9/09 8:23 AM Page 6

(b) 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 8). 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. 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.

A fresh Battery should last about one year. When Battery power

is low and replacement is necessary, the Alarm will “beep” and

the LED will flash at the same time about once per minute for

at least 30 days. The battery must then be replaced. Replace

the battery if the alarm does not sound when the Test Button is

pressed. For maximum reliability, replace battery at least once

a year.

Test the alarm for correct operation using the test button

whenever the battery is replaced.

If the Power Indicator 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 label inside Smoke

Alarm Cover.

WARNING: Use of any other battery may be detrimental to the

operation of the Smoke Alarm.

B10274-R4-105B-U&C-ENG 30/9/09 8:23 AM Page 7

(d) 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

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.

Interconnecting your Smoke Alarms

A maximum of 12 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. The unit can be also connected to Ei100C Ionization

type Smoke Alarms. Do not connect to any other device as it

may damage the unit or affect performance.

A maximum of 5,000 feet (1,500 metres) 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 in

figure 9 before screwing to ceiling). 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 the detectors should alarm

and the test button on the first unit will flash about once a

second. 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.

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.

• For replacement batteries, refer to label inside smoke alarm.

• NOTE: Constant exposure to high or freezing temperatures or

high humidity may reduce the life of the batteries.

• Do not disconnect battery to stop alarm sounding. (Fanning

vigorously with a newspaper or similar will remove nuisance

smoke from the Smoke Alarm and stop it sounding.)

B10274-R4-105B-U&C-ENG 30/9/09 8:23 AM Page 8

• Do not attempt to recharge or burn batteries, as they may

explode. Wrap in paper and discard normally.

• When removing battery, 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 12.)

• This appliance is intended for household use ONLY and not

for commercial or industrial use.

• 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 fatalaties 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, or if the wrong type of battery is

used. Test regularly and replace batteries at least yearly or

when 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 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.

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.

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.

(b) 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.
