CHECK OPERATION OF ALARM

GREEN MAINS LIGHT IS ON.

TEST BUTTON OPERATES ON ALL ALARMS.

ALL INTERCONNECTED ALARMS OPERATE WHEN EACH TEST BUTTON IS PRESSED FOR 10 SECONDS.

(Ei144/146 ONLY) IF THE UNIT BEEPS EVERY 40 SEC

ONDS FOR OVER20 MINUTES THE BATTERY IS PROB

ABLY DEPLETED. REMOVE UNIT FROM CEILING (SEE FIG 1) AND REPLACE BATTERY. ON THE Ei164/166 UNITS ALLOW CELLS TO CHARGE FOR 2 HOURS (MAINS ON).

DO NOT ATTEMPT TO OPENTHE ALARM AS IT IS PER

MANENTLY SEALED FOR SAFETY.

IF A NUISANCE ALARM OCCURS PRESS THE TEST/HUSH BUTTON TO SILENCE THE ALARM FOR 10 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:

(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 thetop intactas shown. Thereis only oneposition suitable for the surface wiring to enter the alarm.

6. Carefully alignthe mounting plate andscrew 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 thetest/hush buttonfor 10 seconds.The hornwill sound.

CAUTION: Do not attemptto 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 onor near thedistribution 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: Amaximum oftwelve Ei143/144/145/146/ 164/166Smoke or

Heat Alarms maybe interconnected along with an Ei

128 pattress

with relay (see Accessories below).

(If youwish to connectmore than twelvealarms contact yourdistrib

utor). Systemsusing more than 3or 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 incorpo

rated into the system and be readily accessible to all occu

pants sothat thesource of analarm canbe 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: Donot connectthese Alarms toany other typeof Ei

Alarm, or to any other model produced by another manufac

turer, apart from thoselisted above. Doing this may damage the

Alarms and could result in a shock or fire hazard.

The interconnectwire (minimum0.75mm

cable) mustbe treated as

if it was live. It should be insulated and sheathed.

A maximumof 250metres of wirecan beused (maximum resistance between detectors 50 ohms).

These Smoke/HeatAlarms shouldbe interconnected onlywithin the confines ofa single family livingunit. If theyare connected between different units theremay be excessive nuisance alarms.Everybody may not be aware thatthey 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 thatthe functioning of the mains batteryback-up is checked directly after installation as follows:

(i) Turn offthe mains power at the distributionboard and check that the green mains indicator on the alarm is extinguished.

(ii) Press the testbutton and ensure that the horn sounds loudly for 10 seconds. Ensure that any interconnected alarms also sound.

(iii) Repeatthe process on all interconnectedalarms on the system. Turn the mains power on only if the units pass the above test.

(iv) Check thatthe green mains indicator lightis on. (If it isoff 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 secondsto ensure the sensor chamber, electronics andsounder are working. The red lighton the cover willflash while horn is sounding.The alarm will stop whenthe 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 recommendtesting with smoke or heat as theresults can be misleading unless special apparatus is used.

Interconnected alarms

Test the firstunit by pressing thebutton. All the detectors should alarm within about 5 seconds of the first horn sounding and the red light on thefirst unit only will flash once a second. Checkall the otherunits similarly. (Note:Heat alarms signal toother inter

connected alarms about4 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. Ifit is depleted it will give a short beep every 40 seconds.

Models Ei144 & Ei 146 only

Before replacingthe battery,check that thebeeps arenot due toone of the following:

(i) battery snaps not connected properly.

(ii) Onthe Optical SmokeAlarm only (

EI 146/145)if the unitbeeps

and the redlight does not flash atthe same time it indicatesa prob

lem with the smokechamber - see Cleaning the Smoke Alarm section below.

If the beeps have continued for over 20 minutes (and the other causes of beepshave been ruled out -see below) the battery must be replaced.

(iii) Switch off themains and remove the unit as shownin 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. Ifit 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 Eveready522). We recommend that the “use by date” onthe battery should still haveat least 2 years togo. 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 thegreen mains power light is on. Ifit is off the Alarm has beenpowered fromthe cells andthe beeps indicatethey 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 asthey charge up. Fullycharged, the cells willprovide up to 6 months back-up without mains power.

(iii) On the Optical Smoke Alarms only (

EI 166) if the unit beeps

and the redlight does not flash atthe same time it indicatesa prob

lem with the smoke chamber - see Cleaning the Smoke Alarm.

If all ofthe above possible causes ofbeeps have been ruled outbut the beepinghas stillpersisted for over2 hours withthe green lighton

- 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 twoshort beeps abouta second apart atthe end of thehush 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 Ei128 module has a relayrated 250V AC /5 amps. This isuse

ful for remote signalling and turning on lights.

(b) Smoke Alarm Locator Ei 159:

The SmokeAlarm locator isrecommended for systemswith 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 interconnected alarms for 10 minutes, exceptthose sensing fire. It is easily installed between the interconnect and neutral terminals.

(2) The Heatalarms (Ei 143/144/164) give twobeeps 10 minutes

after the test/hush button is pressed.

(3) Ifthe Optical units(EI 146/145/166) beepswithout the redlight

flashing atthe same time, thechamber is defective.Clean the chamber.

4. INTERCONNECTED ALARMS DO NOT ALL SOUND:

(1) Holdtest button for10 seconds afterfirst alarm has sounded

to ensure signal is transmitted to all units.

(2) Switch off mains and check that live, neutral and intercon

nect cableshave beencorrectly connected andthat the con

nections are tight.

1. FREQUENT NUISANCE ALARMS OCCUR:

(1) Close kitchen / bathroom door when in use.

(2) Ensurethat the alarmis sited at least6m away fromsources

of fumes.

(3) Contamination from insects,paint or paint fumes may have

occurred. Clean the alarm - see “User Instructions” leaflet.

(4) If theproblem persists, resiting of theunit 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 flashrapidly 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) Pressthe test/hush button tosilence the Smoke/HeatAlarm

for 10 minutes.

(4) Ifalarm does notstop, switchoff mains andremove 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 batteryis correctly connected and the unithas beeped for over 20 minutes thebattery 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 mainspower light is on. If not, check fuse, cir

cuit breakersand wiring connections. Ifthe green light isoff, the lithium cells will deplete after some months without mains and will need tobe recharged. If the above fails toturn on the green light, a fault may exist. Switch off mains and remove the unit (see figure 1).

(All Alarms)

(1) If thegreen mains light is onand replacing battery, recharg
