MINUTES.

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 torespond quickly. It also needsto be in aposition 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 requiretwo

or moreto ensure thata reliable early warningis
given. Formaximum protectionyou should putindividual 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 mostlikely sources of fire (living room orkitchen for ex

­ample), but itshould not be more than 7.5metres from the door
to anyroom wherea fire mightstart on theescape route fromthe
house.

Important: These Smoke/Heat Alarms are designed for a sin

­gle occupancy in a residential type environment.

A Smoke Alarmshould be sited within 3m ofbedroom doors for
improved audibility.

HEAT ALARMS

The HeatAlarm givesa fire warningwhen thetemperature at the
unit reaches58°C. Itis ideal forkitchens, garages, boilerhouses
and other areas where thereare 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 HeatAlarm shouldonly be usedin a roomadjoining anescape
route, inconjunction withSmoke Alarms onthe escaperoutes.

All the Heat Alarms and Smoke Alarms should be intercon

­nected to ensurethe early warning will be heard,particularly by
somebody sleeping.A properly designed earlywarning 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 escaperoutes 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 thedoor before adequate warning can begiven by
detectors in the corridor. (Smoke leakingout from a room is of

­ten cool andslow moving so itcan take a long timeto rise to the
ceiling, and travel to a detector which could be some distance
away). AHeat Alarmin the closedroom will giveearly warningof
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 typicaltwo storey house. Note the spac­ings in “Recommended Protection” which ensure the early de­tection of fire and that warning will be heard.

Locate Heat Alarms in rooms adjoining or on escape routes ­kitchens, garages, boiler housesetc. where Smoke Alarms are
unsuitable. Install within 5.3m of potential sources of fire.

Single Storey Dwelling.

If the Home is onone level (a bungalow or mobile home for ex

-

ample) youshould put thefirst Smoke Alarmin a corridoror hall

­way between the sleeping and living areas. Place it as near to
the living areaas possible, but make sureyou can hear it loudly
enough towake aperson in thebedrooms. (for example,see fig

­ure 3)

If the bungalowis very large and the corridoror hallway is more
than say15 metres long,one Smoke Alarm willnot be sufficient.
This isbecause no matter where itis located it willbe 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 theyare allinterconnected. The livingroom isthe most likely
place for afire to start at night, followed bythe kitchen and then
the dining room. You should also consider putting Smoke
Alarms in any bedrooms where fires might occur, for instance,
where thereis anelectrical appliance suchas an electricblanket
or heater, or where the occupant is a smoker. You could also
consider putting Smoke Alarms in any rooms where the occu

­pant is unableto respond very well to afire 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 soundingin its intended location, check you are
able to hear itin each bedroom with the door closed,above the
sound ofthe radio. The radioshould be set toa reasonably loud
conversation level. If you can’t hear it over your radio the
chances are that it wouldn’t wake a person.

If aSmoke Alarm is toofar away forit to wakea person, it isbest
to lnterconnect to another SmokeAlarm or HeatAlarm 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 couldcause nuisance
alarms.

·

Near adecorative object, door, light fitting,window mould­ing etc., that may prevent smoke or heat from entering the

Alarm.

· Surfaces that are normally warmer or colder than the rest

of the room (forexample 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. thatcan change thedirec

-

tion of airflow.

·

In veryhigh or awkward areas(eg. over stairwells) whereit
may be difficult to reach the alarm (for testing, hushing or
battery replacement).

·

Locate awayfrom verydusty or dirtyareas asdust build-up
in thechamber canimpair performance. Itcan also blockthe
insect screen mesh and prevent smoke from entering the
smoke detector chamber.

·

Locate theunit at least 1 metrefrom dimmer controlled lights
and wiring - some dimmers can cause interference.

·

Locate unitat least1.5m androute wiringat least 1m awayfrom
fluorescent light fittings aselectrical “noise” and/or flickering
may affect theunit. Do not wire into thesame circuit as fluores

-

cent lights or dimmers.

·

Do not locate in insect infested areas. Small insects get

­ting intothe smoke detectorchamber can causeintermittent
alarms. Insects and contamination onthe Heat Alarm sen

­sor can increase its response time.

·

The locationsmust complywith applicable buildingregulations.

Hot smokerises and spreads out, soa central ceiling positionis
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 unitat least 0.5m ) from any light
fitting ordecorative objectwhich might obstructsmoke / heaten

-

tering the Alarm. Keep at least 0.5m away from walls. See fig

­ure 4.(Smoke Alarms shouldbe locateddirectly on theceiling or
up to 0.57mbelow it. Heat Alarms should be locateddirectly on
the ceiling or up to 90mm below it).

Wall mounting is not recommended for these Alarms.

Sloping Ceiling

In areaswith sloping orpeaked ceilings installyour 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-interminal block toconnect itto the mains.The mount

­ing plate can be screwed directly to the ceiling. Alternatively it
can bescrewed to a standard junctionbox. It requires acurrent
of 40mA. TheAlarm must not be exposedto dripping or splash

­ing. Thereare importantmarkings on theunderside ofthe alarm.

IMPORTANT PRECAUTION: Do not install the actual

alarm itself in new or renovated buildings until all

work is
completed (including floorcoverings) and the buildinghas
been fullycleaned. The wiringcan be installed whenappro

­priate. (Excessive dust and debris from building work can
contaminate the smokechamber or heat sensor andcause
problems, it willalso invalidate the guarantee).If it must be
installed, cover it completely, particularly around the
edges, witha dustcover (eg. withthe elasticated coversup

­plied or a plastic bag), until all cleaning is finished.

The Alarmmust not

be connectedwhen the housewiring insula

-

tion is being checked with high voltages.

WARNING:

Mains operated Alarms should beinstalled and in

­terconnected by a qualified electrician in accordancewith local
institutions. Failureto installthis Alarm correctlymay expose the
user to shock or fire hazards.

An ALL-POLE MAINS SWITCH witha contact separation of at
least 3mmin each poleshall be incorporated inthe electricial in

­stallation of the building.

WARNING:

The Alarmmust be continuously powered24 hours
a dayso it isimportant that itis not on acircuit that canbe turned
off by a switch.

INSTALLATION

1. Select a location complying with the above advice.

2. Disconnect theAC mains supply from the circuitthat is going
to be used.

3. Remove the mounting plate from the Smoke/Heat Alarm by re

­leasing thetamper-proof catch with asmall screwdriver asshown in
figure 1 and sliding the Alarm from the plate.

4. The housewiring must be connected tothe 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 - connectto the third core. (If you arenot 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. Thealarm does notneed to beearthed. However thetermi­nal marked is providedfor the convenienceof theinstaller so
that any copper earth wire or cable coloured green or green &
yellow, can be safely terminated.

To interconnectthe Alarms connect allthe IC terminalstogether
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:
