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.

• 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 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.

B14355-R4-TY-UC-ENG-3105 21/12/10 1:30 PM Page 2

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.

Recommended locations, Figures 1, 2, & 3

for minimum protection

• on each storey

• in each sleeping area

• every 7.5 metres of hallways & rooms

• within 3 metres of all bedroom doors

for maximum protection

• in every room (except bathrooms and kitchens)

Figure 3: Multi Storey Dwelling

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.

B14355-R4-TY-UC-ENG-3105 21/12/10 1:30 PM Page 4

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 Alarms must be

mounted 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 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 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.

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

separating at rear snap-in hinges by rotating cover

backwards.

B14355-R4-TY-UC-ENG-3105 21/12/10 1:30 PM Page 6

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.

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.

Figure 6

B14355-R4-TY-UC-ENG-3105 21/12/10 1:30 PM Page 7

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

nuisance false alarms.

Figure 7

B14355-R4-TY-UC-ENG-3105 21/12/10 1:30 PM Page 8

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.

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.

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

B14355-R4-TY-UC-ENG-3105 21/12/10 1:30 PM Page 9

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 into a fire.
