LOCATING ALARMS
SMOKE ALARMS
Sufficient smoke must enter the Smoke Alarm before it will
respond. The Smoke Alarm needs to be within 7.5 metres (25
ft)ofthefiretorespondquickly.Italsoneedstobeinaposition
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 warningisgiven.Formaximumprotectionyoushouldput
individual Smoke Alarms in all the rooms where fire is most
likely to break out, (apart from kitchens, bathrooms 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
example).Itshouldnotbemorethan7.5metres(25ft)fromthe
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
single occupancy in a residential type environment.
ASmokeAlarmshouldbesitedwithin3mofbedroom doorsfor
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
housesandotherareaswherethere arenormallyhighlevels of
fumes, smoke or dust i.e. places whereSmoke Alarms cannot
be installed without the risk of excessive nuisance alarms.
A Heat Alarm should only be used in a room adjoining an
escaperoute,inconjunctionwithSmokeAlarmsonthe escape
routes.
All the Heat Alarms and Smoke Alarms should be
interconnected to ensure the early warning will be heard,
particularly by somebody sleeping. A properly designed early
warning fire system ensures the alarm is given before the
escape routes become 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 outfromaroomis oftencoolandslowmoving soitcan
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
closedroomwill giveearlywarningoffireinthatroomandhelp
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
spacingsin“RecommendedProtection”which ensuretheearly
detection of fire and the warning will be heard.
Locate Heat Alarms in rooms adjoining or on escape routes -
kitchens,garages,boilerhousesetc.whereSmokeAlarmsare
unsuitable. Install within 5.3m (17 feet) of potential sources of
fire.
Single Storey Dwelling.
If the Home is on one level (a bungalow or mobile home for
example) you should put thefirst Smoke Alarm ina corridor or
hallwaybetween thesleepingandlivingareas.Placeitasnear
to the living area as possible, but make sure you can hear it
loudlyenoughtowakeaperson inthebedrooms.(for example,
see figure 3) Single storey Dwelling with Recommended

Ifthebungalowisverylarge andthecorridororhallway ismore
than say 15 metres (50 ft) long, one Smoke Alarm will not be
sufficient.Thisisbecausenomatter whereitislocateditwillbe
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
interconnected 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
likelyplacefor afire tostartatnight,followedbythe kitchenand
then the diningroom. Youshould also considerputting 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 alsoconsiderputting SmokeAlarms inanyrooms where
the occupant is unable to respond very well toa fire starting in
the room, such as an elderly or sick person or a very young
child.
Fire Authorities (including the Home Office, UK) recommend
that both Optical and Ionisation Smoke Alarms should be
fitted for the fastest response to all types of fires. An Optical
Alarmshouldbelocateddownstairsto detectslow smouldering
fires (e.g. from a cigarette burning in a couch or bedding,
overheated PVC wiring etc). An Ionisation Alarm should be
located upstairs to detect fast flaming fires(e.g. paper burning
inacontaineroragreasefireinthekitchen)which couldrapidly
block the main escape route.
Checking you can hear the Smoke & Heat Alarms
WiththeAlarmsoundinginitsintendedlocation,checkyouare
abletohearit ineachbedroomwiththedoorclosed,abovethe
soundofthe radio.Theradioshouldbe settoareasonablyloud
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 interconnect to another Smoke Alarm or Heat Alarm
near the bedroom, so when one alarm senses fire, all
interconnectedalarmsrespond(seebelowforfurtherdetails).
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
(104°F) or be below 4°C (39°F) 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
moulding etc., that may prevent smoke or heat from
entering the Alarm.
•
Surfacesthatarenormallywarmerorcolderthantherestof
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
direction of airflow.
•
In veryhigh orawkward areas(eg.over stairwells)where it
may be difficult to reach the alarm (for testing, hushing or
battery replacement).
• Locateawayfromverydusty ordirtyareas asdustbuild-up
inthechambercanimpairperformance. Itcanalsoblock the
insect screen mesh and prevent smoke from entering the
smoke detector chamber.
•
Locate the unit at least 1 metre (3 feet) from dimmer
controlled lights and wiring - some dimmers can cause
interference.
•
Locateunitatleast 1.5m(5feet)androutewiringatleast1m
(3 feet) away from fluorescent light fittings as electrical
“noise” and/or flickering may affect the unit.
•
Donotlocateininsectinfestedareas.Smallinsectsgetting
into the smoke detector chamber can cause intermittent
alarms. Insectsandcontamination ontheHeatAlarmsensor
can increase its response time.
POSITIONING SMOKE/HEATALARMS
Thelocationsmustcomplywithapplicablebuildingregulations.
Hotsmokerisesandspreadsout,so acentralceilingpositionis
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 300mm (12 inches)
from any light fitting or decorative object which might obstruct
smoke / heat entering the Alarm. Keep at least 300mm (12”)
away from walls. See figure 4. (Smoke Alarms should be
located directly on the ceiling or up to 570mm below it. Heat
Alarms should belocated directlyon theceiling or upto 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 90mm (3 feet) from the highest point
measured horizontally(seefigure 5),because “deadair”at the
apex may preventsmoke from reaching theunit.
INTERCONNECTING SMOKE/HEAT
ALARMS
When a fire is sensed the alarm must be given throughout the
house. Up to twenty (20) Smoke Alarms (models EI 180, 181,
185, 186 only) and Heat Alarms (model EI 183, 184 only) can
be interconnected so that when one senses fire all alarm.
Caution: Do not interconnect to any other type of alarm.
Theunitinitiatingthe alarmcanbeidentifiedbytheredLEDon
the cover flashing every second. Figure 6 shows the
interconnect wiring.
Note:Itisonly necessarytowireonerelay tothecontrolpanel.
If any alarm senses fire this relay will change state due to the
signal on the interconnect line.
These Alarms should be interconnected only within the
confines ofasinglefamilylivingunit. Iftheyareinterconnected
between different units there may be excessive nuisance
alarms.Everybodymaynotbeawarethattheyarebeingtested
or thatitisa nuisancealarmcausedbycooking etc.Whenone
unit alarms all relays will switch.
Systems using more than 3 or 4 alarms mustbe 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 incorporated
into the system and be readily accessible to all occupants so
that the source of an alarm can be quickly identified. (see
Accessory section).
All Alarms must be cleaned and maintained regularly.
A competent person must be on call to quickly remove any
faulty alarms (i.e. units with red light flashing), which are
causing all alarms to sound.
INSTALLING SMOKE/HEAT ALARMS
The Alarm is designed to be permanently mounted , using it’s
own built-in terminal blocks to connect it to the panel. The
mounting plate can be screwed directly to the ceiling after
connecting the wires.
IMPORTANTPRECAUTION:Donot installtheactualalarm
itself in new or renovated buildings until all work is
completed(includingfloor coverings)andthebuildinghas
been fully cleaned. The wiring can be installed when
appropriate. (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 supplied or a plastic bag), until all
cleaning is finished.
Warning: Wiring should only be installed by an Electrician in
accordance with current IEE wiring regulations for electrical
installation. The installation must also be in accordance with
thecontrolpanelinstructionsandtheinstructionsinthisleaflet.
Warning: The mains circuit used to power the control panel
must be a 24 hour voltage circuit and be wired on a separate
circuit (one with no other lights or applilances) to ensure
maximum reliability of the supply.
Warning: The Alarms must be connected to a panel that
supplies a permanent voltage that cannot be switched off.
Warning: For safety reasons the voltage supply from the
control panel must not be greater than 30V (peak or d.c.) and
mustbeeitherindependentofthesupplymainsorisolatedfrom
it by double or reinforced insulations.
Warning:IfthecontrolpanelisnotprovidedwithanALL-POLE
MAINSSWITCH(withacontactspecificationofatleast3mmin
each pole), then the electrical installation of the building shall
incorporate an ALL-POLE MAINS SWITCH, (with a contact
separation of at least 3mm in each pole).
Installation
Select a location complying with the above advice.
1. Remove the mounting platefrom theSmoke Heat Alarmby
releasing the tamper-proof catch with a small screwdriver as
shown in figure 1a and sliding the alarm from the plate.
2.Liftthefoamflapcoveringthecircuitonthe mountingplate.If
necessary movethejumpersonS1and/orS2 (seefigure7)by
carefully lifting them and placing them over the required pins.
3. If surface wiring the unit remove the required breakaways.
Low voltage signal cable is satisfactory (e.g. wire 0.22mm

)
providedtheresistancebetweentheunitsandthepanelisless
than 20 ohms.
All wiring must comply with local codes. Connect the wires to
the terminals as shown in the wiring diagram (figure 6). The
gasket flap can be tucked behind the terminals while this is
being done. Place gasket flap back over circuit board and
terminals.
4.Carefullyalignthemountingplateandscrewintoplace.With
recessed wiring,ensurethereargasket sealsaroundtheedge
ofthehole intheceiling.Thisis topreventairdraughtsaffecting
the smoke / heat entering the alarm. If the orificeis too large it
should be sealed with silicone rubber or equivalent.
Check the battery is connected in the back of the alarm ( EI
181, 184, 186 only).
Carefully line up the unit on the base and slide on.
Press the test/hush button for 10 seconds. The horn should
sound (EI 181, 184, 186 only).
7.Connectthepanelpowertothealarmcircuit.Thegreenlight
on the mounting plate should turn on.
Check the operation of the Alarm as outlined in the next
section.
CHECKING AND MOUNTING YOUR
ALARMS
INSPECTION & TESTING PROCEDURE
After installation, after re-occupation following a holiday, and
weekly, check all your Alarms as follows:
Checkthegreenlightisilluminatedonthemountingplate.This
shows the panel is supplying power.
Press the test button for up to 10 seconds to ensure the
sensor chamber, electronics and sounder are working. A red
light on the cover will flash while horn is sounding. The relay
contacts should change over with the EI185, EI186 relay
contacts when the horn sounds with the EI180, EI181, EI183,
EI184, it contacts within 6 seconds after the horn sounds. 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.
Wedonotrecommendtestingwith smokeorheatastheresults
can be misleading unless special apparatus is used.
Check for any sign of contamination such as cobwebs or dust
and clean the alarm as described below if necessary.
Interconnected alarms
Test the first unit by pressing the button. All the detectors
should alarm within about5 seconds of thefirst horn sounding
and the red light on the first unit only will flash once a second.
The relay contacts should change over about 6 seconds after
the horns sound. Check all the other units similarly. (Note:
Ionisation and Heat alarms signal to other interconnected
alarms, about 4 seconds after their own horn sounds. Optical
alarms signal within about a second).
