1.BASIC INFORMATION ABOUT YOUR SMOKE ALARM
A Smoke Alarm is an early warning device. Installing Smoke Alarms can give you and your family valuable extra time to escape.
Note:-
•Install as close to the centre of the ceiling as possible.
•Press the Test Button weekly.
•Replace the battery once a year or when the Alarm beeps once every minute and the red light flashes at the same time.
•If the Alarm beeps without the LED flashing at the same time the unit must be cleaned.
•A Smoke Alarm does not prevent fires.
•Plan your escape route.
•Proper protection may require more than one Smoke Alarm.
•If you have any questions or doubts about Smoke Alarms contact the supplier or your local Fire Brigade.

2. LOCATING SMOKE ALARMS
Sufficient smoke must enter the Smoke Alarm before it will respond. Your Smoke Alarm needs to be within 10 paces (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 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 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 (except bathroom and kitchen).
Your first Smoke Alarm should be located between the sleep- ing area and the most likely sources of fire (living room or kitchen for example). But it should not be more than 10 paces (7.5 metres) from the door to any room where a fire might start and block your escape from the house.
Important: This Smoke Alarm is only suitable for domestic use.

a) Single Storey Dwelling
If the home is on one level (a bungalow or mobile home for example) you should put the 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 a person in the bedrooms. (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
3
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. We strongly recommend that Smoke Alarms are fitted on each story.
c) 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 kitchens, bathrooms etc., see “Locations to Avoid”). 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 occupant 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.
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 a per- son.
If a Smoke Alarm is too far away for it to wake you, it is best to interconnect it to another Smoke Alarm near the bedroom. A maximum of twelve Smoke Alarms may be interconnected (See page 1 for the model numbers of Smoke Alarms with interconnect), so that all interconnected Alarms respond when one Alarm senses smoke (see page 9 for further details).
3. POSITIONING YOUR SMOKE ALARM
Position your Smoke Alarm to comply with applicable building regulations.

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 0.5 m from any light fitting or decorative object which might obstruct smoke entering the Smoke Alarm. Keep at least 0.5 m away from walls and corners. (see Figure 4)
Wall mounting is not recommended for Smoke Alarms.
b) Mounting on a Sloping Ceiling
In areas with sloping or peaked ceilings install your Smoke Alarm 90 cm from the highest point measured horizontally, because “dead air” at the apex may prevent smoke from reaching the unit.
c) Locations to Avoid
Don’t place your Smoke Alarm 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 m away from potential sources of fumes.
•Locate away from very dusty or dirty areas as dust build- up in the chamber can make unit too sensitive and prone to alarm. It can also block the insect screen mesh and pre- vent smoke from entering the smoke detector chamber.
•Do not locate in insect infested areas. Small insects get- ting into the smoke detector chamber can cause intermit- tent alarms.
d) 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 fam- ily into a safe place, before you start investigating.
Check the entire house/apartment carefully in case there is a small fire smouldering somewhere.
Check whether there is some source of smoke or fumes, for example cooking fumes being drawn past the Smoke Alarm by an extractor.
If there are frequent nuisance/false Alarms it may be neces- sary to relocate the device away from the source of the fumes.
Fanning vigorously with a newspaper or similar will help silence the Alarm by removing smoke from the sensing chamber.

WARNING: Smoke Alarms do not function without a battery.
5.LOOKING AFTER YOUR SMOKE ALARM
a)Automatic
The smoke chamber automatically tests itself every 40 sec- onds. If the chamber is degraded the unit will beep, without the LED flashing at the same time. If this happens clean the unit.
b) Checking the Smoke Alarm | Figure 8 |
It is recommended that you test your Smoke Alarm at least once a week to be sure the unit is work-
•Attics or other places where extremes of temperature may occur (below 4oC or above 40oC).
•Near a decorative object, door, light fitting, window moulding etc., that may prevent smoke from entering the Smoke Alarm.
•Surfaces that are normally warmer or colder than the rest of the room (for example attic hatches, uninsulated exteri- or 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 direction 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 least 1.5m and route wiring at least 1 m away from fluorescent light fittings as electrical “noise” and/or flickering may affect the unit.
•Locate the unit at least 1 metre from dimmer controlled lights and wiring - some dimmers can cause interference.
4.INSTALLING YOUR SMOKE ALARM
a)The Smoke Alarm is battery powered with no need for elec- trical wiring (unless units are being interconnected, see page 9).
1.Pull cover open at tab. Do not remove the base from the back of the Smoke Alarm.
2.Find a suitable location, place the base of the Smoke Alarm against the ceiling and mark the position of the screw holes with a pencil.
3.Taking care to avoid any electrical wiring in the ceiling drill two holes through the centres of the marked locations, insert wall plugs and screw the unit into place.

b) Connecting the Battery
Using a pencil, note the date you inserted the battery on the inside of the base for future reference. Remove the battery from the battery holder and connect to the battery connector, (see Figure 7).
Figure 7
9Volt Battery
Battery Connector
The Ei Electronics Smoke Alarm is fitted with a battery con- nector to make connecting the battery safer.
Check the Smoke Alarm as outlined on page 8.
c) Safety Lock
All models are fitted with a warning flag (safety interlock), which pops up preventing the cover from being closed when no battery is inserted. When inserting or replacing a battery the flag must be pushed down into the battery holder.
ing properly. Press and hold the Test Button until the Alarm sounds (it may take up to 10 sec- onds), (see Figure 8). It will also help you and your family to become familiar with the sound of the Alarm.
c) Replacing the Battery
Fresh batteries should last about one year. When the battery is nearly depleted and needs to be replaced the unit beeps once a minute for at least 30 days. The alarm will stop beep- ing when the battery has been replaced. Also replace the bat- tery if pressing the test button does not cause the Alarm to sound. For maximum reliability, replace the battery at least once a year.
Insert the new battery as soon as possible to ensure proper functioning of the unit. Leakage could cause damage to the Alarm, furniture, and carpeting.
A flashing light every 40 seconds (without the unit beeping) does not mean that the battery needs to be replaced.
Note: Also check proper functioning of the Smoke Alarm after
