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 /
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
5

6
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

9
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.

10
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.
