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.

¥ Models Ei405 & Ei405C - connect battery snaps firmly (see

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

¥ Models Ei405C, Ei405TY & Ei405TYC - slide unit on to

mounting plate to connect the batteries.

¥ 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 fea-

ture indicating the chamber is degraded.

¥Plan your escape route.

¥Proper protection usually requires more than one Smoke

Alarm.

¥If you have any doubt or query about Smoke Alarms con-

sult the supplier or your local Fire Brigade.

¥Models Ei405TY & Ei405TYC - 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.

¥Models Ei405 & Ei405C - When the Alarm beeps and the

red light flashes at the same time replace the battery (see

The wireless interconnect will operate as received once the

batteries are connected. (Program units if nearby systems are like-

ly to cause false alarms).

2. INTRODUCTION

Congratulations on purchasing Ei405 Radio 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 Radio Smoke Alarms offer the comfort of intercon-

nection without the hassle of installing the interconnect wires.

The wireless interconnect helps ensure the alarm will be

heard everywhere - including most importantly, 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) and then hold down the test but-

ton on the first unit until the blue light comes on continuously

for 3.5 seconds. All the other smoke alarms will respond with-

in 5 seconds. If there is any possibility of a neighbour having

a similar system, you should program your units so your sys-

tem will not cause his/hers to alarm or vice versa. This is eas-

ily done and only takes a few minutes- see below (section 6.3).

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 dis-

turbance 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.

3. 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. 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 max-

imum 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 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

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.

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 Radio

smoke alarms are ideal in this situation as they are automati-

cally interconnected without wiring.

3.3 Recommended Protection

For recommended 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.

3.4 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 Hi-Fi System. The Hi-Fi

system 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 Wireless interconnect smoke

alarms will help to ensure the alarm will be heard through-out

the house.

4. POSITIONING YOUR SMOKE ALARM

4.1. 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 (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 5.

4.2 Wall Mounting

When a ceiling position is not possible (for example on a ceil-

ing having exposed beams or joists, or built-in radiant heat-

ing) 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 5).

4.3 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 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 exteri-

or 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.

¥Locate unit at least 1.5m away from fluorescent light fit-

tings 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 pre-

vent smoke from entering the chamber.

¥Do not locate in insect infested areas. Small insects get-

ting in to the chamber can cause intermittent alarms.

4.5 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 fam-

ily into a safe place, before you start investigating.

Check the house carefully in case there is a small fire smoul-

dering 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 neces-

sary to re-locate the device away from the source of the

fumes.

If you installed the smoke alarms as received and did not pro-

gram them, you may be receiving an alarm signal from a

neighbouring system. This can be easy rectified by house

coding your alarms (see section 6.3).

Pressing the test & hush button on the smoke alarm sensing

fire (i.e. with the red light flashing rapidly) will silence the

alarm for 10 minutes. (Pressing the hush button on the option-

al Ei 410 Remote Control acts in the same way).

5. INSTALLING YOUR SMOKE ALARMS

1. Select a location complying with the above advice.

2. Remove the mounting plate from the Smoke Alarm by

releasing the tamperproof catch with a small screwdriver as

shown in figure 1a and sliding 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. 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.

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

1b (models Ei405 & Ei405C only).

6. Carefully line up the unit on the base and slide on. (This

connects the batteries in the Ei 405C, TY, TYC units.

Install all the other alarms similarly.

6. LOOKING AFTER YOUR SMOKE ALARMS

6.1 Manually Testing your Smoke Alarm

It is recommended that you test your Smoke Alarm at least

weekly 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 (Figure 7). The

alarm will stop sounding shortly

after the button is released. Figure 7

If the alarm fails to sound, follow this checklist:

¥Check the age of the unit - see the replace by label on

base of unit.

¥Check the battery snaps are firmly connected on the Ei405

& Ei405C models (see fig 1b).

¥On the Ei405TY & Ei405TYC models ensure the unit is

pushed fully home on the mounting plate, as this connects

the battery.

¥Check for any sign of contamination such as cobwebs or

dust and clean the alarm as described on page 12 if nec-

essary.

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 mis-

leading unless special apparatus is used.

6.2 Checking the Wireless Interconnect

We recommend that the interconnect is tested weekly as

follows:

1. Press and hold the test button on the first alarm for 5 sec-

onds (count up to 10).

2. The horn will sound and then the blue light will come on

continuously for 3.5 seconds. (This indicates that the unit is

transmitting a Radio Alarm signal to the other units). Release

the test button. The local alarm will cease and you should

then be able to hear the other alarms sounding in the dis-

tance.

3. Repeat this procedure for all the other alarms.

If any units appear not to operate remove models (Ei405 &

Ei405C only) from the mounting plate (as shown in figure 1a)

and ensure battery is firmly connected to the snaps. If the

wireless link does not appear to operate ensure you have held

the test button down until the blue light has come on continu-

ously (this could take up to 5 seconds).

(If there still appears to be a problem with the wireless link it

may be necessary to resite/rotate some units - see section

below on "House Coding your Units").

We strongly recommend that you house code your units so

that your system will not be triggered by similar systems in the

neighbourhood.

6.3 House Coding your Units

The units can transmit and receive over 150 metres minimum

(in free space) so it is important to ensure neighbouring sys-

tems do not interfere with your system. The following proce-

dure programs the units so each learns the serial numbers of

all the other units on the system. After they have been pro-

grammed they will only communicate with units programmed

at the same time (that were within range).

Program Procedure

1. Press the test button on the first installed unit three times

within 1.5 seconds. The blue light will come on momentarily

each time to show the button is operating. (If the horn sounds

during these short button depressions, just ignore it). The blue

light will now flash once every 5 seconds. The unit now sends

a radio message every 5 seconds stating it is in the program

mode and containing its own serial number. It is also looking

for similar messages from other units.

2. Similarly press the test button three times on the second

installed unit. After about 30 seconds each of the two units

will be flashing the blue light twice every 5 seconds to indicate

it has detected and learned the serial number of two units (i.e.

itself and the other unit).

3. Similarly press the test button on the third unit, three times

to put it in the program mode. After about 30 seconds all the

units will be flashing the blue light three times every 5 sec-

onds to indicate there are now three units on the system.

4. Similarly press the test button three times on all the other

units to put them in the program mode. (If a Remote Control

Ei410 is to be used it must also be put into the program mode

at this time by holding the Test and Locate button down

simultaneously (see "RF Remote Control" section below). On

each smoke alarm the blue light will flash rapidly to show the

number of units with which it has communicated.

The units will stay in program mode for 15 minutes and then

reset automatically. ( A smoke alarm can be taken out of pro-

gram mode quickly by pressing the test button three times in

1.5 seconds).

N.B. The quickest method of programming the system is to

put all units into the program mode at the same time.

Additional Units

Additional RF alarms can be added to the system at any time.

Siimply put all the units, the additional units and those previ-

ously installed, into the program mode at the same time.

6.4 Troubleshooting RF Interconnection

If, for example, there are 6 units in the system, but two of the

units are only flashing 5 times, it indicates that these two units

are not communicating. Try resiting / rotating the units (e.g.

move it away from metal surfaces or wiring) until they both

flash 6 times while in the program mode.

Note: Resiting/rotating units may move them out of the range

of existing units even though they may have learned all serial

numbers in the system. It is important therefore to check that

all 6 detectors are communicating in their final installed posi-

tions.
