SMOKE ALARMS
Sufficient smoke must enter the Smoke Alarm before it will re-
spond. The Smoke Alarm needs to be within 7.5 metres of the
fire to respond quickly. It also needs to be in a position where its
alarm can be heard throughout your home, so it can wake the
occupants in time for 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,
(apart from kitchens etc. see Locations to Avoid).
A Smoke Alarm should be located between the sleeping area
and the most likely sources of fire (living room or kitchen for ex-
ample), but it should not be more than 7.5 metres from the door
to any room where a fire might start on the escape route from the
house.
Important: These Smoke/Heat Alarms are designed for a sin-
gle occupancy in a residential type environment.
A Smoke Alarm should be sited within 3m of bedroom doors for
improved audibility.
HEAT ALARMS
The Heat Alarm gives a fire warning when the temperature at the
unit reaches 58°C. It is ideal for kitchens, garages, boiler houses
and other areas where there are normally high levels of fumes,
smoke or dust i.e. places where Smoke Alarms cannot be in-
stalled without the risk of excessive nuisance alarms.
A Heat Alarm should only be used in a room adjoining an escape
route, in conjunction with Smoke Alarms on the escape routes.
All the Heat Alarms and Smoke Alarms should be intercon-
nected to ensure the early warning will be heard, particularly by
somebody sleeping. A properly designed early warning fire sys-
tem ensures the alarm is given before the escape routes be-
come blocked with smoke. Therefore, there must be Smoke
Alarms along the escape routes as Heat Alarms would not give
sufficient warning. However, a fire in a closed room (e.g.
kitchen) adjoining the escape route, can eventually cause the
corridor to become smoke-logged due to smoke leaking out
from around the door before adequate warning can be given by
detectors in the corridor. (Smoke leaking out from a room is of-
ten cool and slow moving so it can take a long time to rise to the
ceiling, and travel to a detector which could be some distance
away). A Heat Alarm in the closed room will give early warning of
fire in that room and help overcome this problem.
RECOMMENDED LOCATIONS
Figure 2 illustrates where Smoke Alarms and Heat Alarms
should be located in a typical two storey house. Note the spac-
ings in “Recommended Protection” which ensure the early de-
tection of fire and that warning will be heard.
Locate Heat Alarms in rooms adjoining or on escape routes -
kitchens, garages, boiler houses etc. where Smoke Alarms are
unsuitable. Install within 5.3m of potential sources of fire.
Single Storey Dwelling.
If the Home is on one level (a bungalow or mobile home for ex-
ample) you should put the first Smoke Alarm in a corridor or hall-
way 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 a person in the bedrooms. (for example, see fig-
ure 3)
If the bungalow is very large and the corridor or hallway is more
than say 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.
Multi Storey Dwellings
If the dwelling has more than one storey it must have an inter-
connected alarm on each level for minimum protection.
Maximum Protection
For maximum 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). Ensure
that they are all interconnected. 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 occu-
pant 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.

Checking you can hear the Smoke & Heat Alarms
With the Alarm sounding in its intended location, check you are
able to hear it in each bedroom with the door closed, above the
sound of the radio. The radio 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 a person.
If a Smoke Alarm is too far away for it to wake a person, it is best
to lnterconnect to another Smoke Alarm or Heat Alarm near the
bedroom. The alarms can be interconnected - when one alarm
senses smoke, all interconnected alarms respond (see below
for further details).
LOCATIONS TO AVOID
Don’t place Smoke Alarms in any of the following areas:
·Bathrooms, kitchens, shower rooms, garages or other
rooms where the smoke alarm may be triggered by steam,
condensation, normal smoke or fumes. Keep at least 6
metres (20 feet) away from sources of smoke.
Don’t place Heat Alarms in any of the following areas:
·Bathrooms, shower rooms or other room where the unit
may be triggered by steam or condensation.
Don’t place Smoke or Heat Alarms in any of the following areas:
·Places where the normal temperature can exceed 40°C or
be below 4°C e.g. attics, furnace rooms etc. directly above
ovens or kettles, as the heat/steam could cause nuisance
alarms.
·Near a decorative object,door,light fitting,window mould-
ing etc., that may prevent smoke or heat from entering the
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 or
heat from reaching the unit.
·Next to or directly above heaters or air conditioning
vents,windows,wall vents etc. that can change the direc-
tion of airflow.
·In very high or awkward areas (eg. over stairwells) where it
may be difficult to reach the alarm (for testing, hushing or
battery replacement).
·Locate away from very dusty or dirty areas as dust build-up
in the chamber can impair performance. It can also block the
insect screen mesh and prevent smoke from entering the
smoke detector chamber.
·Locate the unit at least 1 metre from dimmer controlled lights
and wiring - some dimmers can cause interference.
·Locate unit at least 1.5m and route wiring at least 1m away from
fluorescent light fittings as electrical “noise” and/or flickering
may affect the unit. Do not wire into the same circuit as fluores-
cent lights or dimmers.
·Do not locate in insect infested areas. Small insects get-
ting into the smoke detector chamber can cause intermittent
alarms. Insects and contamination on the Heat Alarm sen-
sor can increase its response time.
·
The locations must comply with applicable building regulations.
Hot smoke rises and spreads out, so a central ceiling position is
the preferred location. The air is “dead” and does not move in
corners, therefore Smoke & Heat Alarms must be mounted
away from corners. Place the unit at least 0.5m ) from any light
fitting or decorative object which might obstruct smoke / heat en-
tering the Alarm. Keep at least 0.5m away from walls. See fig-
ure 4. (Smoke Alarms should be located directly on the ceiling or
up to 0.57m below it. Heat Alarms should be located directly on
the ceiling or up to 90mm below it).
Wall mounting is not recommended for these Alarms.
Sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke/Heat
Alarm 0.9m from the highest point measured horizontally (see
figure 5), because “dead air” at the apex may prevent smoke
from reaching the unit.
The Alarm is designed to be permanently mounted , using it’s
own built-in terminal block to connect it to the mains. The mount-
ing plate can be screwed directly to the ceiling. Alternatively it
can be screwed to a standard junction box. It requires a current
of 40mA. The Alarm must not be exposed to dripping or splash-
ing. There are important markings on the underside of the alarm.
IMPORTANT PRECAUTION:Do not install the actual
alarm itself in new or renovated buildings until all work is
completed (including floor coverings) and the building has
been fully cleaned. The wiring can be installed when appro-
priate. (Excessive dust and debris from building work can
contaminate the smoke chamber or heat sensor and cause
problems, it will also invalidate the guarantee). If it must be
installed, cover it completely, particularly around the
edges, with a dust cover (eg. with the elasticated cover sup-
plied or a plastic bag), until all cleaning is finished.
The Alarm must not be connected when the house wiring insula-
tion is being checked with high voltages.
WARNING: Mains operated Alarms should be installed and in-
terconnected by a qualified electrician in accordance with local
institutions. Failure to install this Alarm correctly may expose the
user to shock or fire hazards.
An ALL-POLE MAINS SWITCH with a contact separation of at
least 3mm in each pole shall be incorporated in the electricial in-
stallation of the building.
WARNING: The Alarm must be continuously powered 24 hours
a day so it is important that it is not on a circuit that can be turned
off by a switch.
INSTALLATION
1. Select a location complying with the above advice.
2. Disconnect the AC mains supply from the circuit that is going
to be used.
3. Remove the mounting plate from the Smoke/Heat Alarm by re-
leasing the tamper-proof catch with a small screwdriver as shown in
figure 1 and sliding the Alarm from the plate.
4. The house wiring must be connected to the terminal block on
the mounting plate as follows:
L: Live - connect to the house wires coloured brown, red or
marked L.
N: Neutral - connect to the house wires coloured blue, black or
marked N.
IC: Interconnect - connect to the third core. (If you are not inter-
connecting units, do not connect anything to the IC terminal).
(See below for information on interconnecting).
Warning: Mixing Live & Neutral wires will damage intercon-
nected alarms.
We recommend the use of 6243Y mains cable when intercon-
necting units. Use the third core for interconnection.
Do not use an earth wire for the interconnect line.
Lift off the wiring cover as shown in Fig 6.
N.B. The alarm does not need to be earthed. However the termi-
nal marked is provided for the convenience of the installer so
that any copper earth wire or cable coloured green or green &
yellow, can be safely terminated.
To interconnect the Alarms connect all the IC terminals together
as shown in Figure 8.
5. If the mains wires are recessed, bring the wires through the
rear hole in the mounting plate as shown in figure 7.
If the mains wires are being brought along the surface:
(a) position the mounting plate so the cable trunking is as shown
in figure 7.

(b) carefully cut around the knockouts on the two alarm side
walls so it blends with the contours of the alarm sidewall.
Important: only cut the thinned down knockout section and
leave the top intact as shown. There is only one position suitable
for the surface wiring to enter the alarm.
6. Carefully align the mounting plate and screw into place. Con-
nect the wires to the terminal block. With recessed wiring, en-
sure the rear gasket seals around the edge of the hole in the
ceiling or wall. This is to prevent air draughts affecting the
smoke / heat entering the alarm. If the orifice is too large it
should be sealed with silicone rubber or equivalent.
Replace the wiring cover. Check the battery is connected (140
series only).
Carefully line up the unit on the base and slide on.
Press the test/hush button for 10 seconds. The horn will sound.
CAUTION: Do not attempt to remove the Alarm without first re-
leasing the tamper clip as shown in Figure 1.
7. Connect the mains power to the alarm circuit. Check the
green light is on. Attach the label provided to the distribution
board to identify the alarm circuit.
Attach the ‘Mains Smoke / Heat Alarm’ label on or near the distri-
bution board and write in date installed and the number of
alarms on the circuit.
Check the operation of the Alarm as outlined below.
INTERCONNECTING EI ELECTRONICS SMOKE / HEAT
ALARMS
Note: A maximum of twelve Ei143/144/145/146/ 164/166 Smoke or
Heat Alarms may be interconnected along with an Ei 128 pattress
with relay (see Accessories below).
(If you wish to connect more than twelve alarms contact your distrib-
utor). Systems using more than 3 or 4 alarms must be very carefully
planned to ensure nuisance alarms are not excessive. e.g. from
cooking or weekly testing.
·Smoke Alarm Locator Switch (EI 159) should be incorpo-
rated into the system and be readily accessible to all occu-
pants so that the source of an alarm can be quickly identified.
·All alarms must be cleaned and maintained regularly.
·A qualified person must be on call to quickly remove any
faulty alarms (i.e. units with red light flashing), which are
causing all the alarms to sound.
WARNING: Do not connect these Alarms to any other type of Ei
Alarm, or to any other model produced by another manufac-
turer, apart from those listed above. Doing this may damage the
Alarms and could result in a shock or fire hazard.
The interconnect wire (minimum 0.75mm2cable) must be treated as
if it was live. It should be insulated and sheathed.
A maximum of 250 metres of wire can be used (maximum resistance
between detectors 50 ohms).
These Smoke/Heat 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.
INSPECTION & TESTING PROCEDURE
After installation check all the Alarms
We recommend that the functioning of the mains battery back-up is
checked directly after installation as follows:
(i) Turn off the mains power at the distribution board and check that
the green mains indicator on the alarm is extinguished.
(ii) Press the test button and ensure that the horn sounds loudly for
10 seconds. Ensure that any interconnected alarms also sound.
(iii) Repeat the process on all interconnected alarms on the system.
Turn the mains power on only if the units pass the above test.
(iv) Check that the green mains indicator light is on. (If it is off check
circuit breakers, fuses and wiring etc.) Check the red light on the
cover flashes every 40 seconds.
(v) Press the test button for up to 10 seconds to ensure the sensor
chamber, electronics and sounder are working. The red light on the
cover will flash while horn is sounding. The alarm will stop when the
button is released. Pressing the test button simulates the effect of
smoke or heat during a real fire and is the best way to ensure the
Alarm is operating correctly.
WARNING: DO NOT TEST WITH FLAME.
This can set fire to the Alarm and damage the house.
We do not recommend testing with smoke or heat as the results
can be misleading unless special apparatus is used.
Interconnected alarms
Test the first unit by pressing the button. All the detectors should
alarm within about 5 seconds of the first horn sounding and the
red light on the first unit only will flash once a second. Check all
the other units similarly. (Note: Heat alarms signal to other inter-
connected alarms about 4 seconds after their own horn sounds.
Optical alarms signal within about a second.
Checking Battery Back-up
When the unit is beeping:
The Alarm automatically monitors the battery every 40 seconds to
ensure that it is satisfactory. If it is depleted it will give a short beep
every 40 seconds.
Models Ei144 & Ei 146 only
Before replacing the battery, check that the beeps are not due to one
of the following:
(i) battery snaps not connected properly.
(ii) On the Optical Smoke Alarm only (EI 146/145) if the unit beeps
and the red light does not flash at the same time it indicates a prob-
lem with the smoke chamber - see Cleaning the Smoke Alarm sec-
tion below.
If the beeps have continued for over 20 minutes (and the other
causes of beeps have been ruled out - see below) the battery must
be replaced.
(iii) Switch off the mains and remove the unit as shown in figure 1a.
Remove depleted battery and replace with one of the specified 9V
alkaline batteries. The alarm cannot be replaced on the mounting
plate unless a battery is installed. After replacing the battery, slide
on the mounting plate then press the test button and ensure horn
sounds loudly before you turn on the mains. If it is satisfactory turn
on the mains and check that the green light comes on. Note: Only
use the specified Alkaline batteries shown on the base label
(Duracell MN1604 or Eveready 522). We recommend that the “use
by date” on the battery should still have at least 2 years to go. Older
batteries will give beeps prematurely. We recommend that the bat-
tery is replaced each year for optimum performance.
Models Ei161, Ei164 & Ei 166 only
(i) Check that the green mains power light is on. If it is off the Alarm
has been powered from the cells and the beeps indicate they are de-
pleted. Re-connect the mains, check fuse, circuit breakers and wir-
ing. If in doubt contact a qualified electrician. The beeps should
cease within 2 hours as the cells charge up.
(ii) The cells may be depleted. The beeps should cease within 2
hours as they charge up. Fully charged, the cells will provide up to 6
months back-up without mains power.
(iii) On the Optical Smoke Alarms only (EI 166) if the unit beeps
and the red light does not flash at the same time it indicates a prob-
lem with the smoke chamber - see Cleaning the Smoke Alarm.
If all of the above possible causes of beeps have been ruled out but
the beeping has still persisted for over 2 hours with the green light on
- the rechargeable cells are probably defective. The Smoke / Heat
Alarm must be returned to the manufacturer for repair or replace-
ment (see section Getting Your Alarm Serviced).
(Please note: The ionisation alarms (EI140/141/161) give two short
beeps about a second apart at the end of the hush period (i.e. about
10 minutes after test/hush button has been pressed. These two
beeps should not be confused with low battery beeps.
(a) Relay Module EI 128:
The Ei 128 module has a relay rated 250V AC / 5 amps. This is use-
ful for remote signalling and turning on lights.
(b) Smoke Alarm Locator Ei 159:
The Smoke Alarm locator is recommended for systems with three or
more Smoke / Heat Alarms as it helps quickly identify the unit in
alarm and reduces the impact of nuisance alarms.
Pressing the Smoke Alarm Locator button will silence all intercon-
nected alarms for 10 minutes, except those sensing fire. It is easily
installed between the interconnect and neutral terminals.
(2) The Heat alarms (Ei 143/144/164) give two beeps 10 minutes
after the test/hush button is pressed.
(3) If the Optical units (EI 146/145/166) beeps without the red light
flashing at the same time, the chamber is defective. Clean the
chamber.
4. INTERCONNECTED ALARMS DO NOT ALL SOUND:
(1) Hold test button for 10 seconds after first alarm has sounded
to ensure signal is transmitted to all units.
(2) Switch off mains and check that live, neutral and intercon-
nect cables have been correctly connected and that the con-
nections are tight.

1. FREQUENT NUISANCE ALARMS OCCUR:
(1) Close kitchen / bathroom door when in use.
(2) Ensure that the alarm is sited at least 6m away from sources
of fumes.
(3) Contamination from insects, paint or paint fumes may have
occurred. Clean the alarm - see “User Instructions” leaflet.
(4) If the problem persists, resiting of the unit should be consid-
ered.
2. ALARM SOUNDS FOR NO APPARENT REASON:
(1) Identify the alarm source. On interconnected units, the red
light on the cover will flash rapidly only on the unit which is
the source of the alarm.
(2) Check for fumes, steam etc. from the kitchen or bathroom.
Paint and other fumes can cause nuisance alarms.
(3) Press the test/hush button to silence the Smoke/Heat Alarm
for 10 minutes.
(4) If alarm does not stop, switch off mains and remove unit (see
figure 1). (Only remove alarm with red light flashing, the others are
probably satisfactory).
3. LOW BATTERY & OTHER BEEPS:
(On Ei144/146 only)
If the battery is correctly connected and the unit has beeped for
over 20 minutes the battery is probably depleted. Obtain a new
battery, disconnect the mains, then remove the alarm and re-
place the depleted battery.
(On Ei164/166 only)
Check the green mains power light is on. If not, check fuse, cir-
cuit breakers and wiring connections. If the green light is off, the
lithium cells will deplete after some months without mains and
will need to be recharged. If the above fails to turn on the green
light, a fault may exist. Switch off mains and remove the unit
(see figure 1).
(All Alarms)
(1) If the green mains light is on and replacing battery, recharg-
ing lithium cells or cleaning unit has not stopped beeps, a
fault may exist. Disconnect the mains first and replace the
unit (see figure 1).
