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.

When the alarm sounds, immediately evacuate the premises

before beginning any investigation.

1. Install in the centre of the ceiling (if possible) using the

screws supplied (see section 5.0).

2. Connect battery: Connect battery snaps firmly (see figure

1). Press the test button and horn should sound.

3. 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.

4. The wireless interconnect will operate as received once

the batteries are connected. We strongly recommend

house coding your alarms to prevent interference from

neighbouring systems (see section 6)

5. Test weekly.

6. Proper protection usually requires more than one Smoke

Alarm.

7. If the Ei3105RF Smoke Alarm beeps without the red light

flashing at the same time then clean the unit, as this is the

automatic test feature indicating the chamber is degraded.

8. A Smoke Alarm does not prevent fires.

9. Plan your escape route.

10. If you have any doubt or query about Smoke Alarms

consult the supplier or your local Fire Brigade.

2. INTRODUCTION

Congratulations on purchasing Ei3105RF or Ei3100RF /

Ei3500RF RadioLINK Smoke Alarms. You can easily install

these alarms throughout the house in closed rooms, corridors

and in insulated attics for the fastest response to developing

fires.

Closed doors are great for slowing down the spread of

fire, but unfortunately they can also greatly slow down the

response time of alarms, as they block the smoke getting

to them. Without interconnection, closed doors also greatly

reduce the alarm sound level throughout the house, so even

though the fire is detected early, the alarm may not be heard.

The Ei3105RF and Ei3100RF / Ei3500RF Radio Smoke

Alarms offer the comfort of interconnection without the hassle

of installing the interconnect wires. The wireless interconnect

helps ensure the alarm will be heard everywhere - including

the bedrooms.

The wireless interconnect will operate as received once the

batteries are connected. To check operation, first connect

all the batteries (see section 1, para 2.) and then hold down

the test button on the first unit until the amber light comes

on continuously for 3 seconds. All the other smoke alarms

will respond within 5 seconds. If there is any possibility of a

neighbour having a similar system, you should house code

your units so your system will not cause his/hers to alarm or

vice versa. This is easily done and only takes a few minutes-

(see section 6.0).

3. LOCATING YOUR SMOKE ALARMS

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. The smoke alarms

need to be in positions where they can be heard throughout

your home, so they can wake you and your family in time for

everyone 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 recommended protection you should put individual

Smoke Alarms in all the rooms (apart from the kitchen) 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.

3.1 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 2).

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.

3.2 Multi Storey Dwellings

If your home has more than one floor, at least one alarm

should be fitted on each level (see figure 4). The Ei3105RF

and Ei3100RF / Ei3500RF Wireless Smoke Alarms are ideal

in this situation as they are automatically interconnected

without wiring.

3.3 Recommended Protection

Fire authorities recommend you put individual Smoke Alarms

in or near 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.

3.4 Checking you can hear your Smoke Alarms

With the Smoke Alarms sounding in their intended locations,

check you are able to hear them in each bedroom with the

door closed, above the sound of your Audio/TV Systems.

The Audio/TV systems 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. These RadioLINK

Smoke Alarms will help to ensure the alarm will be heard

through-out the house.

4. POSITIONING YOUR SMOKE ALARM

4.1 On a ceiling

Hot smoke rises and spreads out, so a central ceiling position

is the recommended 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 from any

light fitting or decorative object which might obstruct smoke

entering the Smoke Alarm. Keep at least 0.3m away from

walls and corners (see figure 5).

4.2 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 below the ceiling. Keep at least 0.3m from corners.

(see figure 5).

4.3 On a sloping Ceiling

In areas with sloping or peaked ceilings install your Smoke

Alarm 0.90m from the highest point measured horizontally

(see figure 6), because “dead air” at the apex may prevent

smoke from reaching the unit.

4.4 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 (uninsulated) 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 or battery replacement.

• Locate unit at least 1.5m away from fluorescent light

fittings as electrical “noise” and/or flickering may affect the unit.

in to the chamber can cause intermittent alarms.

5. INSTALLING YOUR SMOKE ALARMS

5.1 Attaching to Ceiling

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.

(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.

Battery Missing indicator

The unit is 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).

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 replace the cover match up snap-in hinges and gently

press together until base and cover snap together. Test the

installed Smoke Alarm - see section 7 “Manually Testing your

Smoke Alarm (page 10)”.

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

Connectors to the Battery.

4.Check the radio link interconnection by holding the test

button down until the amber light has come on continuously

– this indicates that the alarm is now transmitting radio link

signals. You should now be able to hear the other alarm(s)

in the distance. If you do not hear the other alarm(s) (see

section 5.2 below).

5. The units, as received, will transmit and receive the default

RF signal. However, to avoid other neighbouring systems

interfering with your alarms, we recommend that you “house

code” your alarms.

Install all the other alarms similarly.

5.2 If RadioLink is not working

It is imperative that all smoke alarms in your system

communicate with each other. The number of walls, ceilings

and metal objects in the radio link signal path reduces the

strength of the radio link signals between the smoke alarms.

Accordingly, one or more smoke alarms may have difficulties

in communicating to all the other units in the system.

It is recommended that with systems of 3 or more alarms one

central unit is made into a Repeater Unit (see section 6 below).

If, when checking the radio link interconnection, some of the

alarms do not respond to the button test, then you will need

Figure 8

to make one a repeater, or rotate / re-locate the units. There

are a number of reasons why the radio link signals may not

reach all the smoke alarms in your system (see section 10.2

on “Limitations of Radio Frequency Signals”). However, you

should try making one unit into a repeater, rotating the smoke

alarms or re-locating the smoke alarms (e.g. move them away

from metal surfaces or wiring).

Rotating and/or re-locating the smoke alarms may move

them out of the range of existing smoke alarms even though

they may have already been house coded correctly in the

system. It is important therefore to check that all detectors

are communicating in their final installed positions. If smoke

alarms are rotated and/or resited, we would recommend

that all the smoke alarms are returned to the factory settings

and then house coded again in their final positions (see

section 6.0). The radio link interconnection should then be

re-checked again.

6. HOUSE CODING YOUR ALARMS

House coding your alarms will prevent neighbouring alarm

systems from setting off your own alarms and vice versa.

The house coding process changes the radio signal from the

common factory signal to a unique radio code for each unit.

6.1 House Code Procedure

Ensure that the battery is connected to all alarms before

beginning the house code procedure.

1. Open the cover by pulling the tab. Press the house code

switch and hold until the amber light comes on and then

release. The amber light will then flash rapidly for about 1

second to indicate the unit is now in the house code mode

(see figure 9).

2. Similarly press and hold the house code switch on the

second installed unit until its amber light comes on and then

release. Put all the remaining alarms into the house code

mode in the same manner.

3. When in the house code mode, the amber light will flash a

number of times every 5 seconds to indicate:

(a) the alarm is in house code mode and

(b) the number of units that have been identified as being part

of your system.

For example with 3 alarms in your system, you should see

3 amber light flashes every 5 seconds, with 4 alarms in your

system you should see 4 amber light flashes and so on. The

maximum number of light flashes that can be seen is 12. It is

recommended that a maximum of 12 units are interconnected.

(Please note that during the house coding process one alarm

may sound for 1 minute.)

Check that the number of amber light flashes corresponds to

the number of units in the system. If not see section 5.2.

4. The units will stay in house code mode for 15 minutes and

then reset automatically. Alternatively they can be taken out of

house code mode quickly by pressing and holding the house

code switch until the amber light comes on again. The amber

light will go out immediately when the switch is released,

indicating that the alarm is no longer in house code mode.

(Note: The Wireless Alarms can be returned to the originally

factory settings by pressing and holding the house code

switch on until the amber light flashes slowly. This will take

about 6 seconds. This cancels the house code mode.

Additional Wireless Smoke Alarms can be added to the

system at any time. Simply put all the units, the additional

units and those previously installed, into the house code

mode at the same time.

Boosting the RadioLINK Range

Making an Ei3105RF or Ei3100RF / Ei3500RF Repeater Unit

In the normal installations (single storey and two-storey

houses), the RF signal range should be sufficient to activate

the alarms. However, in certain circumstances some alarms

may not receive the radio link signals and then it will be

necessary to set up an alarm as a repeater smoke alarm.

The function of the repeater smoke alarm is to receive and

re-broadcast the signals, so effectively boosting the signal

range throughout the installation. We recommend that when

three or more alarms are installed a centrally positioned

unit is converted into a repeater unit.

To make a repeater unit:

(i) Choose a centrally positioned Smoke Alarm

(ii) Press and hold the test button until the alarm sounds and

the amber light comes on, then immediately (while the light

is on) press and hold the House Code switch until the amber

light flashes slowly. (The amber light will flash 15 times to

indicate that the Smoke Alarm is in Repeater Mode).

Note: It is recommended that only one Smoke Alarm be

designated as a repeater unit in any house installation. More

then one repeater unit in any single system may cause signal

interference and could result in units not communicating with

each other.
