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.

¥ 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
fig 1).
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 interconnection 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 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 program 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 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
4
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.
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 maximum 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 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.

areas.
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 automatically 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 ceiling having exposed beams or joists, or built-in radiant heating) 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 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.
¥ 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 prevent 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 family into a safe place, before you start investigating.
Check the house carefully in case there is a small fire smouldering somewhere.
Check whether there is some source of smoke or fumes, for
example cooking fumes being drawn past the Smoke Alarm
by an extractor.
8
If there are frequent nuisance/false alarms it may be necessary to re-locate the device away from the source of the
fumes.
If you installed the smoke alarms as received and did not program 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 optional 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
9
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 necessary.
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 misleading 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 seconds (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 distance.
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 continuously (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 systems do not interfere with your system. The following procedure programs the units so each learns the serial numbers of
all the other units on the system. After they have been programmed they will only communicate with units programmed
at the same time (that were within range).
10
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 seconds 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 program 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 previously 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 positions.
11
Clear the serial numbers learned by:
- disconnecting the battery
- waiting 10 seconds
- holding the test button down while re-connecting the battery
snaps to the Ei405 & Ei405C only. With the Ei405TY &
Ei405TYC models hold the test button down while sliding it on
to the mounting plate.
Then put it into the program mode by pressing the test button
three times within 1.5 seconds. It will now flash the blue light
once every 5 seconds indicating there is just one unit (i.e.
itself) in the system.
Put all the other units into the program mode and confirm that
the blue light on each unit is flashing 6 times every 5 seconds
indicating that RF links are now all satisfactory.
RF Remote Control Ei 410 (Optional)
The optional Remote Control Ei410 allows you to test, hush or
locate units.
Test:
Press Test button on remote control. The red light on the control will come on continuously to indicate it is transmitting an
RF signal. The Smoke Alarms within range will alarm in
10 seconds, with the red light on the smoke alarm flashing
rapidly. (This indicates that the chamber has been tested in
exactly the same way as if the test button on the unit itself had
been pressed).
Hush:
If a unit is giving a nuisance alarm e.g. from cooking fumes,
pressing the Hush button on the remote control, within range
of the alarm, will silence it for 10 minutes. Note only units
sensing smoke i.e. with their red light flashing rapidly, will
have their smoke sensitivity reduced. However, all units will
be silenced.
Locate:
If all the units are in alarm due to one sensing smoke, pressing the Locate button on the remote control within range of
each unit will silence all units except ones sensing smoke.
(Note this is different to the operation of the Hush button
which silences all units). This is a very useful feature, when
for example twelve units are alarming simultaneously, as the
unit initiating the alarm can be quickly indentified (even in a
closed bedroom) and the problem quickly resolved.
House Coding:
If you are house coding your Smoke Alarms you must also
include the Remote Control. It is put into program mode by
holding down the Test & Locate buttons simultaneously
until the red light flashes. The flashing will continue for 15
minutes indicating the remote control is in program mode.
12
The unit can be quickly removed from the program mode by
holding down the Test & Locate buttons simultaneously.
(The house coding can be removed, if necessary, from the
remote control by first disconnecting the battery for 10 seconds and then reconnecting the battery while holding down
both the Test & Locate buttons).
6.5 Power Indicator Light.
The Smoke Alarm has a red Power Indicator Light which
flashes once a minute to show the Smoke Alarm is powered.
Check regularly. Replace the Smoke Alarm if the flashing
stops.
6.6 Hush Feature
These smoke alarms have a silencer feature to help you control nuisance false alarms.
1. To cancel a false alarm, press the test & hush button. The
alarm will automatically switch to a reduced sensitivity condition. This condition allows unwanted alarms to be silenced for
a period of approximately 10 minutes. The red light will flash
every 10 seconds (instead of 40 seconds) to let you know the
unit has been silenced. It can also be silenced using the Hush
Button on the optional remote control Ei 410, provided it is
sensing smoke itself.
2. The unit will reset to normal sensitivity at the end of the
silenced period. If additional silenced time is required, simply
push the test button again.
3. If the cause of the alarm is not clear, it should be assumed
that it is due to an actual fire and the dwelling should be
evacuated immediately.
If kitchen usage/layout is such that there are an unacceptable
level of nuisance alarms, re-locate the Smoke Alarm further
away where it will be less affected by cooking fumes etc.
6.7 Cleaning your Smoke Alarm
Clean your Smoke Alarm regularly. Use a soft bristle brush or
the brush attachment of your vacuum cleaner to remove dust
and cobwebs from the sides and cover slots where the smoke
enters. Keep cover closed while cleaning. Do not vacuum or
brush inside the Smoke Alarm.
WARNING: Do not paint your Smoke Alarm.
Other than the maintenance and cleaning described in this
leaflet, no other customer servicing of this product is required.
Repairs, when needed, must be performed by the manufacturer.
13
6.8 Automatic Self-Test
The smoke chamber automatically tests itself every 40 seconds. If the chamber is degraded it will beep without the red
light flashing at the same time. If this happens clean the unit.
If the beeping persists and the beep does not coincide with an
red light flash, return the unit for service (see Getting your
Smoke Alarm Serviced ).
6.9 Dust & Insect Contamination
All Smoke Alarms and particularly the optical (photoelectric)
type are prone to dust and insect ingress which can cause
false alarms.
The latest design, materials and manufacturing techniques
have been used in the construction of our Alarms to minimise
the effects of contamination. However it is impossible to completely eliminate the effect of dust and insect contamination,
and therefore, to prolong the life of the Smoke Alarm you must
ensure that it is kept clean so that excess dust does not build
up. Any insects or cobwebs in the vicinity of the Smoke Alarm
should be promptly removed.
In certain circumstances even with regular cleaning, contamination can build up in the smoke sensing chamber causing
the alarm to sound. If this happens the alarm must be
returned to us for servicing or replacement. Contamination is
beyond our control, it is totally unpredictable and is considered normal wear and tear. For this reason, contamination is
not covered by the guarantee and a charge is made for all
servicing work.
If you experience persistent false alarms, in particular locations, due to contamination of the smoke chamber you could
consider fitting an ionisation type Smoke Alarm. The principle
of ionisation detection makes it less vulnerable to the effects
of dust or insect contamination.
6.10 Replacing the Battery (Model Ei 405 & Ei405C only)
A fresh Alkaline Battery should last for over a year. When the
battery power is low and replacement is necessary, the Alarm
will beep and the red light will flash at the same time about
once per minute for at least 30 days. The battery must then
be replaced. Replace the battery if the alarm does not sound
when the Test Button is pressed. For maximum reliability,
replace the battery at least once a year (see fig 1a for how to
remove unit from the mounting plate).
6.11 End of life
The entire Smoke Alarm must be replaced if:-
(i) The unit is installed for over 10 years (check the replacement year marked on the unit).
14
(ii) Low Battery beeps (Model Ei 405TY & Ei405TYC only)
The unit is giving a short beep every 40 seconds and the red
light flashes at the same time for longer than 1 hour. (If the
unit beeps without the red light flashing at the same time see
Cleaning your Smoke Alarm above).
(iii) The unit fails to sound the horn loudly when the test button is pressed.
Before the Smoke Alarm is discarded, remove from the
mounting plate (Ei405TY & Ei405TYC only) to stop beeps or
the possibility of the unit alarming. With the Ei405 & Ei405C
just disconnect the battery. Do not put the Smoke Alarm
into a fire.
7. HARDWIRE INTERCONNECTION
(Models: Ei 405C & Ei 405TYC only)
Sometimes it may be required to interconnect to battery powered Ei Electronics Smoke Alarms which do not have wireless
interconnect. If any of the interconnected units detect smoke the
Ei 405C & Ei 405TYC model will send a Radio alarm signal.
A maximum of twelve (Ei 405C, Ei 405TYC, Ei 3105TYC, Ei
100TYC, Ei 105C, Ei103C or Ei 100C only) Smoke / Heat
Alarms may be wired together such that when one unit senses smoke all other units sound a warning. This helps ensure
smoke alarms will be heard. Do not connect to any other
device as it may damage the unit or affect performance.
Figure 9
Figure 8
e.g. Ei 105C e.g. Ei 3105TYCH
Ei 405TYC
15
A maximum of 250 metres (820ft) of signal cable can be used,
(maximum resistance between detectors 50 ohm). The units
are interconnected by wiring all the terminals marked 1
together, and all the terminals marked 2 together (as in fig 8)
before screwing the mounting plate to ceiling. Draughts,
through the ceiling, from wiring openings, conduit, or mounting boxes/holes, may blow smoke away from the sensing
chamber, making it insensitive. It is essential that all such
openings including the wiring hole (see figure 9) be closed by
silicone sealant or similar.
1. Remove the Smoke Alarm from the mounting plate as
shown in fig 1a
2. Lift the wiring cover on the mounting plate as shown in fig 9.
3. Connect the two core cable to the terminal block as shown
in fig 10.
4. Replace the wiring cover and attach the smoke alarm to the
mounting plate.
After wiring together the Interconnect Smoke Alarms, test the
first unit by pressing the button. All the detectors should
alarm and the test button on the first unit will flash about once
a second. Please note it can take up to 5 seconds for some
of the interconnected units to sound. Check all the other units
similarly.
Check the Radio Interconnect as described above.
These Smoke Alarms should be interconnected only within
the confines of a single family living unit. If they are connected between different units there may be excessive nuisance
alarms. Everybody may not be aware that they are being tested or that it is a nuisance alarm caused by cooking etc.
8. IMPORTANT SAFEGUARDS
When using household protective devices, basic safety precautions should always be followed, including those listed
below
¥ Please read all instructions.
¥ Rehearse emergency escape plans so everyone at home
knows what to do in case the alarm sounds.
Figure 10
16
¥ Constant exposure to high or freezing temperatures, high
humidity or a high level of nuisance alarms may reduce the
life of the battery.
¥ Nuisance alarms can be quickly silenced by fanning vigor-
ously with a newspaper or similar to remove the smoke or
press the test / hush button.
¥ Do not attempt to remove, recharge or burn the battery, as
it may explode.
¥ If it is necessary to remove the battery for separate dis-
posal, handle carefully to avoid possible eye damage or
skin irritation if battery has leaked or corroded.
¥ To maintain sensitivity to smoke, do not paint or cover
smoke alarm in any manner; do not permit any accumulation of cobwebs, dust or grease.
¥ If unit has been damaged in any way or does not function
properly,do not attempt a repair. Return Smoke Alarm (see
- Getting your Smoke Alarm Serviced).
¥ This appliance is intended ONLY for premises having a
residential type environment.
¥ This is not a portable product. It must be mounted follow-
ing the instructions in this instruction leaflet.
¥ Smoke Alarms are not a substitute for insurance. The sup-
plier or manufacturer is not your insurer.
8.2 Limitations of Smoke Alarms
Smoke Alarms have significantly helped to reduce the number
of fire fatalities in countries where they are widely installed.
However independent authorities have stated that they may
be ineffective in some circumstances. There are a number of
reasons for this:
¥ Smoke Alarms will not work if the batteries are depleted or
if they are not connected. Test regularly and replace the
entire unit when it fails to operate.
¥ Smoke Alarms will not detect fire if sufficient smoke does
not reach the alarm. Smoke may be prevented from reaching the Alarm if the fire is too far away, for example, if the
fire is on another floor, behind a closed door, in a chimney,
in a wall cavity, or if the prevailing air draughts carry the
smoke away. Installing smoke alarms on both sides of
closed doors and installing more than one smoke alarm as
recommended in this leaflet very significantly improve the
probability of early detection.
¥ The Smoke Alarm may not be heard.
¥ Radio Interconnect may not work due to interference or the
signal being blocked by furniture, renovations etc.
¥ A smoke alarm may not wake a person who has taken
drugs or alcohol.
17
¥ Smoke Alarms may not detect every type of fire to give suf-
ficient early warning. They are particularly ineffective with:
fires caused by smoking in bed, escaping gas, violent
explosions. poor storage of flammable rags and/or liquids,
(for example petrol, paint, spirits etc), overloaded electrical
circuits, arson, children playing with matches.
¥ Smoke Alarms don t last indefinitely. The manufacturer
recommends replacement after 10 years as a precaution
¥ Use the Smoke Alarm Test Button to familiarise your fami-
ly with the Alarm sound and to practice fire drills regularly
with all family members. Draw up a floor plan that will show
each member at least 2 escape routes from each room in
the house. Children tend to hide when they don t know
what to do. Teach children how to escape, open windows,
and use roll up fire ladders and stools without adult help.
Make sure they know what to do if the alarm goes off.
9. PLANNING YOUR ESCAPE ROUTE FOR
WHEN THE ALARM GOES OFF
1. Check room doors for heat or
smoke. Do not open a hot door.
Use an alternate escape route.
Close doors behind you as you
leave.
2. If smoke is heavy, crawl out,
staying close to floor. Take short
breaths, if possible, through a wet
cloth or hold your breath. More
people die from smoke inhalation
than from flames.
3. Get out as fast as you can. Do

8.2 FIRE SAFETY HINTS
Store petrol and other flammable materials in proper containers.
Discard oily or flammable rags.
Always use a metal fireplace screen and have chimneys
cleaned regularly.
Replace worn or damaged sockets, switches, home wiring
and cracked or frayed electrical cords and plugs.
Do not overload electrical circuits.
Keep matches away from children.
Never smoke in bed. In rooms where you do smoke, always
check under cushions for smouldering cigarettes and ashes.
Service central heating systems regularly.
Be sure all electrical appliances and tools have a recognised
approval label.
This device cannot protect all persons at all times. It may not
protect against the three most common causes of fatal fires:
1. Smoking in bed.
2. Leaving children at home alone.
3. Cleaning with flammable liquids, such as petrol.
Further information can be obtained from the Fire Brigade.
10. WHAT IS THE BEST SMOKE ALARM OPTICAL OR IONISATION ?
Both types respond in all standard fires but each type may
respond faster to particular fires as shown. Ei Electronics
manufactures two complementary 10 Year Smoke Alarms,
Optical Smoke Alarm Ei 3105TYCH and Ionisation Smoke
Alarm Ei 100TYC with built-in Lithium battery. For dual
pro-
tection install each type.
These can be hard wired interconnected to the Optical
Ei405C or Ei405TYC alarms for wireless transmission of
alarm signal between floors.
Ion Sensor
Best for fast flaming fires
- small smoke particles
Optical Sensor
Best for slow smouldering fires
- large smoke particles
19
The Home Office states (in FB2):
If your home has more than one floor, at least one alarm
should be fitted on each level. In this case, a combination of
Optical and Ionisation alarms, preferably interconnected, will
give the best protection.
