Basic Information about your Smoke Alarm

A Smoke Alarm is an early warning device. Used correctly it can give you and your family valuable extra time to escape.

Note:-

When the battery is first connected the Alarm may sound for

2-3 seconds and/or the LED may flash quickly for 10 sec onds - this is normal.

A Smoke Alarm does not prevent fires.

Install correctly, in the centre of the ceiling if possible.

Test monthly.

When the Alarm beeps and

LED flashes at the same time

replace battery. If the Alarm beeps without

the LED flashing at the same time then clean unit as this is the automatic test feature tell ing you the chamber is degraded.

Plan your escape route.

Proper protection may require more thanoneSmoke Alarm.

If you have any doubt or query about Smoke Alarms consult

the supplier or your local Fire Brigade.

Locating your Smoke Alarm

Sufficient smoke must enter your Smoke Alarm before it will respond. Your Smoke Alarm needs to be within 10 paces (23 feet) 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 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 early warning is given. For maximum protection you should put individual Smoke Alarms in allthe 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 (seven me tres) from the door to any room wherea fire might start and block your escape from the house.

(a) Single Storey Dwelling.

If your Home is on one level (a bungalow or mobile home for ex ample) 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 1)

If your bungalow is very large and the corridor or hallway is more than say 22 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.

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 2).

b) Multi Storey Dwellings

If your home is on more than one level the best place for your first Smoke Alarm is in the downstairs hallway near the stairs. (for example see figure 3). This is because smoke is likely to be detectable in the hallway before it reaches the upstairs landing and bedrooms. Your second Smoke Alarm should be upstairs, because the downstairs Smoke Alarm is unlikely to detect the smoke from a fire in a bedroom upstairs.

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). The living room is the most likely placefor a fire to start at night, followedby 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 orsick person or a very young child.

(d) 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 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 you.

If a Smoke Alarm istoo far away for it towake you, it is bestto link it to another Smoke Alarm near the bedroom. The Interconnect Smoke Alarms EI105C and EI100C are designed for this - when one alarm senses smoke, all connected alarms respond.

Positioning your Smoke Alarm

Figure

IDEAL IN CENTRE OF CEILING

DE AD AIR S PACES NEVER WITHIN 15cm

OF ANY COR NE R

Figure 5

90cm

(a) Ceiling Mounting

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 Alarms must be mounted away from corners. Place the unit at least 30cm (12 inches) from any light fitting or decorative object which might obstruct smoke entering the Smoke Alarm. Keep at least 15 cm (6 inches) away from walls and corners. See figure 4.

(b) Wall Mounting

When a ceiling position is not practical (for example on a ceiling having exposed beams or joists, or built-in radiant heating) put the top edge ofyour Smoke Alarm between 15 and 30 cm (6 and 12 inches) below the ceiling. Keep atleast 15cm(6 inches)from corners. (see figure 4).

In areas with sloping or peaked ceilings install your Smoke Alarm 90 cm (3 feet) from the highest point measured horizon tally (see figure 5), because “dead air” at the apex may prevent smoke from reaching the unit.

(d) Locations to Avoid

Don’t place your Smoke Alarm in any of the following areas:

· Bathrooms, shower rooms, garages or other rooms

where the smoke alarm may be triggered bysteam, condensation, normal smoke or fumes.

· Attics or other places where extremes of temperature may

occur (below 4°C/34°F or above 40°C/104°F).

· Near a decorative object, door, light fitting, window

molding etc., that may prevent smoke from entering the

Smoke Alarm.

Surfaces that are normally warmeror 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 direc

tion of airflow.

In very high or awkward areas where it may be difficult to reach the alarm (for testing, battery replacement etc).

Locate unit at least1.5m (5feet) and route wiring at least 1m (3 feet) away from fluorescent light fittings as electricial “noise” and/or flickering may affect the unit.

Locate away from very dusty or dirty areasas 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.

(e) 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 smoulder ing somewhere.

Check whether there is some source of smoke or fumes, for ex ample cooking fumes being drawn past the Smoke Alarm by an extractor.

If there are frequent nuisance/false alarms it may be necessary to re- locate the device away from the source of the fumes.

Fanning vigorously with a newspaper or similar will help silence alarm.

LABEL

The Smoke Alarm is battery operated and needs only wiring, if the Inter-Link facility is being used.

1. Pull cover open at tab. Remove cover from base by separat ing at rear snap-in hinges by rotating cover backwards.

2. Place the base on ceiling or wall exactly where you want to mount the unit. With a pencil, mark the location of the screw holes.

3. Taking care to avoid any electrical wiring in the ceiling or wall, drill a hole through the centres of the marked locations. Push

the plastic Screw Anchors provided into the drilled holes. Screw in firmly.

(b) Connecting the battery

The battery is easily removed from the holder by holding back one of the plastic clips while lifting the battery with the other hand.

Snap Battery Connectors to Battery. They fit together only one way.

Figure 7

Gently push Battery into Battery Holder

With a pencil, write thedate of battery installation on theinside of the cover to remind you when to replace the battery.

To close the cover match up snap-in hinges and gently press to gether until base and cover snap together. Test the installed Smoke Alarm - see section “Manually Testing your Smoke Alarm”.

NOTE: You may hear a loud chirp when attaching the Battery Connectors to the Battery.

Battery Missing indicator

Some models are fitted with a warning flag which pops up when the battery is removed. This prevents the cover from closing when there is no battery in the unit. When the battery isbeing in stalled or changed, this flag must be held down while gently pushing the Battery into the Battery Holder. (Figure 7(a)).

Figure 7(a)

Looking after your Smoke Alarm

(a) Automatic Self-Test

The smoke chamber automatically testsitself every 40 seconds. If the chamber is degraded it will beep without

the LED flashing at the same time. If this happens clean the unit. If the beeping persists and the beep does not coincide with an LED flash, re turn the unit for service (see “Getting your Smoke Alarm Serv iced”)

(b) Manually Testing your Smoke Alarm

It is recommended that you test your Smoke Alarm at least once a month 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 (it may take up to10 seconds), (Figure 8). The alarm will stop sounding shortly after the Button is released. If the alarm fails to sound, follow this checklist.

1. Check Battery Connectors to be sure they are firmly snapped to the Battery.

2. Replace the Battery. (Check the date marked on the Cover when you last replaced the Battery).

3. Check forany signof contaminationsuch as cobwebs or dust and clean the alarm as described on page 9 if necessary.

Figure 8

Figure 9

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.

A fresh Battery should last about one year. When Battery power is low and replacement is necessary, the Alarm will “beep” and the LED 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 batteryat least oncea

year.

Test the alarm for correct operation using the test button when

ever the battery is replaced.

If the Power Indicator light ceases flashing, replace the battery. Be sure to replace the Battery as soon as possible to ensure proper operation and to avoid a leaking Battery. Leakage could cause damage to the Alarm, furniture, and carpeting.

For replacement batteries, refer to thelabel inside SmokeAlarm Cover.

WARNING: Use of any other battery may be detrimental to the operation of the Smoke Alarm.

(d) 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 from the sides and cover slots where the smoke enters. Keep cover closed while cleaning. Do not vacuum or brush inside the Smoke Alarm. To clean the cover, remove it completely and use only mild soap and water. Dry coverthoroughly before replacing it. 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.

Interconnecting your Smoke Alarms

A maximum of 12 EI 105C Smoke Alarms maybe wired together such that when one unit senses smoke all other units sound a warning. This helps ensure smoke alarms will be heard. The unit can be also connected to EI100C Ionization type Smoke Alarms. Do not connect to any other device as it may damage the unit or affect performance.

A maximum of 5,000 feet (1,500 metres) of 18 AWG (0.82mm) wire 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 figure 9 before screwing to ceiling). Draughts from wiring openings, conduit, or mounting boxes/holes, may blow smoke away from the sensing chamber, making it insensitive. It is es

sential that all such openings be closed by silicone sealant or similar.

After wiring together the Interconnect Smoke Alarms, test the first unit by pressing the button. All the detectors should alarm

PAGE 6,7,8&9

B10274

REV-2

Page 3

and the test button on the first unit will flash about once a sec ond. Check all the other units similarly.

These Smoke Alarms should be interconnected only within the confines of a single family living unit. If they are connected be tween 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.

Important Safeguards

When using household protective devices, basic safety precau tions 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. For replacement batteries, refer to label inside smoke

alarm. NOTE: Constant exposure to high or freezing temperatures

or high humidity may reduce the life of the batteries. Do not disconnect battery to stop alarm sounding. (Fanning

vigorously with anewspaper or similar will remove nuisance smoke from the Smoke Alarm and stop it sounding.)

· Do not attempt to recharge or burn batteries, as they may

explode. Wrap in paper and discard normally.

· When removing battery, 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 page 12.)

This appliance is intended for household use ONLY and not for commercial or industrial use.

This is not a portable product. It must be mounted following the instructions in this instruction leaflet.

Smoke Alarms are not a substitute for insurance. The sup plier or manufacturer is not your insurer.

(b) Limitations of Smoke Alarms

Smoke Alarms have significantly helped to reduce the number of fire fatalaties 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 rea sons for this:

Smoke Alarms will not work if the batteries are depleted or if they are not connected, or if the wrong type of battery is used. Test regularly and replace batteries at least yearly or when depleted.

Smoke Alarms will not detectfire 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 recom mended in this leaflet very significantly improve the prob ability of early detection.

The Smoke Alarm may not be heard.

A smoke alarm maynot wakea personwho hastaken drugs

or alcohol. Smoke Alarms may not detect every type of fire to give suffi

cient early warning. They are particularly ineffective with: fires caused by smoking in bed,escaping gas,violent explo sions. poor storage of flammable rags and/or liquids, (for ex ample petrol, paint, spirits etc), overloaded electrical circuits, arson, children playing with matches.

Smoke Alarms don’t last indefinitely. The manufacturer rec

ommends replacement after 10 years as a precaution.

Planning your Escape for when the Alarm

goes off

Use the Smoke Alarm Test Button to familiarize your family 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 - see below.

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 not stop for packing. Have a prearranged meeting place outside for all family members. Check everybody is there.

4. Call the Fire Brigade from a neigh bour’s house. Remember to give your name and address.

5. NEVER re-enter a burning house.

(b) FIRE SAFETY HINTS

Store petrol and other flammablematerials 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 smoldering cigarettes and ashes.

Service central heating systems regularly.

Be sure all electrical appliances and tools havea recognised ap proval 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 obtainedfrom the Home Office Publication entitled “Smoke Detectors in the Home” (FB2) or from your local fire prevention officer.

IMPORTANT NOTICE

DUST & INSECT CONTAMINATION

All Smoke Alarms and particularly the optical (photoe lectric) type are prone to dust and insect ingress which can cause false alarms.

The latest design, materials and manufacturing tech niques have been used in the construction of our Alarms to minimize the effects of contamination. However it is impossible to completely eliminate theeffect of dustand insect contamination, and therefore, to prolong the life of the SmokeAlarm 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 cham ber 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 our ionisation type Smoke Alarm. The principle of ionisation detectionmakes it less vulnerable to the effects ofdust or insect contamination.

WARNING

DO NOT INSTALL THE ACTUAL SMOKE ALARM IN NEW OR RENO

VATED BUILDINGS UNTIL ALL WORK IS COMPLETED (INCLUDING FLOOR COVERINGS) AND BUILDING HAS BEEN FULLY CLEANED.

(Excessive dust & debris from building work can contaminate the smoke chamber and cause problems).

An installed smoke alarm must be removed or cov ered fully (with a plastic bag or similar) before reno vations begin.
