IMPORTANT
Additional Instructions for the
Radio Interconnect Heat Alarm Ei3103RF
The Ei3103RF Heat Alarm, usually located in the kitchen, must be
used with Smoke Alarms Ei3100RF and/or Ei3105RF located on the
escape route from the house. The Radio Interconnect will help
ensure the alarm is heard through-out the house as all units will
alarm, if one senses fire.
1. For Location & Positioning see section 2 & 3 of the main
instructions.
2. Pull cover open at tab.
3. 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.
4. 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.
5. Connect the battery and close the cover.
6. The Radio Wireless interconnect will now operate. Pressing the
test button on one unit should cause all the others to alarm. (All
alarms are set in default factory mode and will communicate with
each other).
Installing your Heat Alarms
7. However we strongly recommend that you house code your
alarms to prevent your units setting off your neighbour’s alarms or
vice versa.
To house code all your alarms:
7.1 Open the cover by pulling the tab.
7.2 Press the house code switch (see figure 3a) and hold until the
amber light comes on, then release the switch. The amber light will
then flash rapidly for about 1 second to indicate it is now in house
code mode. Leave the cover hanging open.
7.3 Now similarly press the house code switches on all the rest of
the alarms, within 15 minutes, to put them also into house code
mode. (The alarms automatically come out of house code mode
after 15 minutes).
7.4 When in house code mode, the amber light will flash a number
of times every 5 seconds, to indicate the number of alarms that have
been identified as part of your system. For example with 3 alarms in
your system, you should see 3 amber flashes every 5 seconds.
7.5 Check that the number of amber light flashes (on each alarm)
corresponds to the number of units in the system. If this is not the
case repeat the house code procedure. If there is still a problem
rotate or re-locate the units and then house code the units again in
their final position.
7.6 Close the covers on all the units.
Radio Interconnect Heat Alarm Ei3103RF
Note:
(i) The Ei3103RF model does not have a hush button. If there is a
nuisance alarm, fan cooking fumes etc. away from unit with a
newspaper or similar.
(ii) The Ei3103RF cannot be made into a repeater.
(If you think you need a repeater purchase an Ei Electronics Optical
Smoke Alarm Ei3105RF. (A repeater ‘repeats’ the RF signal to
increase the range).
(iii) When the test button is pressed the RF interconnection can be
checked by listening for the other units sounding.
(The test button may need to be held for up to 10 seconds for the RF
message to be sent). If you need clarification contact us at the
details below.

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.

2. INTRODUCTION
Congratulations on purchasing Ei3105RF or Ei3100RF
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 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 con-
tinuously 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 every-
one to escape. A single Smoke Alarm will give some protec-
tion 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 sleep-
ing 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
B15527-R3-3105RF-UC-ENG 14/10/08 9:35 AM Page 3

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 exam-
ple, 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.
Recommended locations, Figures 2, 3, & 4
for minimum protection
• on each storey
• in each sleeping area
• every 7.5 metres of hallways & rooms
• within 3 metres of all bedroom doors
• all units interconnected
for recommended protection
in addition
• in every room (except bathrooms and kitchens)

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 3).

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 Wireless Smoke Alarms are ideal in this situa-
tion 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 liv-
ing room is the most likely place for a fire to start at night, fol-
lowed 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.
Figure 4: Multi Storey Dwelling
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 conver-
sation 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
5
B15527-R3-3105RF-UC-ENG 14/10/08 9:35 AM Page 5

6
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 ceil-
ing 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 air-
flow.
• 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.

• 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.
5. INSTALLING YOUR SMOKE ALARMS
5.1 Attaching to Ceiling
1. Pull cover open at tab. Remove cover from base by sepa-
rating 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.

Snap Battery Connectors to Battery. They fit together only one
way.
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 but-
ton 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 dis-
tance. 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 commu-
nicate 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 to
Figure 8
B15527-R3-3105RF-UC-ENG 14/10/08 9:35 AM Page 8

9
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 com-
municating 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 sec-
ond 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 sec-
ond 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.
