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 the mounting plate in the centre of the ceiling (if pos­sible) using the screws supplied (see section 5.0)

2. Connect battery:

§ Model Ei405 - connect battery snaps firmly (see figure 1a).
Press the test button and horn should sound.

§ Model Ei405TY — sliding the unit on to the mounting plate
will connect the batteries (see figure 1b). 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. Model Ei405 - When the Alarm beeps and the red light
flashes at the same time replace the battery (see figure 7 to
remove unit from the mounting plate).

7. Model Ei405TY - When the Alarm beeps and the red light
flashes at the same time or the blue light flashes every 9
seconds it indicates the battery is depleted and the entire
alarm must be replaced. This normally occurs after 10
years has elapsed (see figure 7 to remove unit from the
mounting plate).

8. Proper protection usually requires more than one Smoke
Alarm.

9. If the 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.

10. A Smoke Alarm does not prevent fires.

11. Plan your escape route.

12. If you have any doubt or query about Smoke Alarms con­sult the supplier or your local Fire Brigade.

2. INTRODUCTION

Congratulations on purchasing Ei405 RadioLINK Smoke
Alarms. You can easily install these alarms throughout the
house in closed rooms, corridors and in the attic 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 Ei405 RadioLINK 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 figure 1) and then hold down the test button
on the first unit until the blue light comes on continuously for

3.5 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).

A remote control Ei410 is available to allow you to test and
hush the alarms, without having to reach up to the smoke
alarms on high ceilings. The remote control also has a
"Locate" button to identify the unit causing the alarm - this is
excellent, particularly at night, as it rapidly identifies where the
fire is located. This is ideal for larger systems, as the distur­bance in the house can be kept to a minimum e.g. no need to
enter all the bedrooms to check to see if the red light is flash­ing rapidly (indicates that the unit is detecting smoke).

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 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 rec­ommended protection you should put individual Smoke
Alarms in all the rooms (apart from the kitchen, where heat
alarms should be used) 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.

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 Ei405/405TY
RadioLINK 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 it 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 0.30m from any
light fitting or decorative object which might obstruct smoke
entering the Smoke Alarm. Keep at least 0.30m away from
walls and corners. See figure 5.

4.2 Wall Mounting

When a ceiling position is not possible (for example on a ceil­ing having exposed beams or joists, or built-in radiant heat­ing) put the top edge of your Smoke Alarm between 0.15m

B15026/R0/RF/UC/ENG/405 1/3/04 5:05 PM Page 6

7

and 0.30m below the ceiling. Keep at least 0.30m 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 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 on Ei405
model.

§ 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

We recommend that up to 12 smoke alarms can be intercon­nected with the radio link. We strongly recommend that all
alarms are house coded during the installation (see section

6).

5.1 Installation Procedure

1. Select a location complying with the above advice.

2. Remove the mounting plate from the Smoke Alarm. If it has

been latched release the tamperproof catch with a small
screwdriver, as shown in figure 7, and slide the alarm from the
mounting plate.

3. Place the base on the ceiling/wall exactly where you want

to mount the unit. With a pencil, mark the location of the two
screw holes.

4. It may be necessary to rotate/resite units to maximise the

radio link signals (see section 5.2). Consequently we advise
to use only one screw initially. Taking care to avoid any elec­trical wiring in the ceiling, drill one hole through the centre of
one of the marked locations. Push the plastic screw anchors
provided into the drilled hole. Screw in firmly. The second
screw may then be used to securely fix the alarm in place
after the radio link interconnection is verified.

5. Connect the battery to the battery snaps as shown in figure

1a (model Ei405 only).

6. Carefully line up the unit on the base and slide on as shown

in figure 1b. (This connects the batteries in the Ei405TY
Smoke Alarm).

7. Press the test button on each alarm to ensure that the

smoke alarm works (see figure 8).

8.Check the radio link interconnection by holding the test but-
