Ei Electronics Smoke Alarm EI105C User Manual

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).  
(a) Ceiling Mounting  
Basic Information about your Smoke Alarm  
Recommended protection, Figures 1,2 & 3  
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.

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

each storey  
b) Multi Storey Dwellings  
each sleeping area.  
Note:-  
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.  
every 7.5 metres (25 ft) of hallways and rooms.  
Maximum protection.  
·
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.  
(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 of your Smoke Alarm between 15 and 30 cm (6 and  
12 inches) below the ceiling. Keep at least 15cm (6 inches) from  
corners. (see figure 4).  
Figure 1: Single Storey Dwelling  
When the Alarm beeps and LED flashes at the same time  
replace battery.  
(c) Maximum Protection  
BEDROOM  
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 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 start-  
ing in the room, such as an elderly or sick person or a very young  
child.  
·
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.  
KITCHEN  
(c) On a sloping Ceiling  
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.  
·

·
Plan your escape route.  
Proper protection may require more than one Smoke Alarm.  
DINING  
If you have any doubt or query about Smoke Alarms consult  
the supplier or your local Fire Brigade.

BEDROOM  
(d) Locations to Avoid  
Locating your Smoke Alarm  
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 by steam, conden-  
sation, normal smoke or fumes.  
Sufficient smoke must enter your Smoke Alarm before it will re-  
spond. 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 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.

separate sleeping areas  
(d) Checking you can hear your Smoke Alarm  
·
·
Attics or other places where extremes of temperature may  
occur (below 4°C/34°F or above 40°C/104°F).  
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 rea-  
sonably loud conversation level. If you can’t hear it over your ra-  
dio the chances are that it wouldn’t wake you.  
KITCHEN  
DINING  
BEDROOM  
Near a decorative object, door, light fitting, window  
molding etc., that may prevent smoke from entering the  
Smoke Alarm.  
RECREATION  
·
·
Surfaces that are normally warmer or colder than the rest of  
the room (for example attic hatches, uninsulated exterior  
walls etc). Temperature differences might stop smoke from  
reaching the unit.  
BEDROOM  
LIVING  
If a Smoke Alarm is too far away for it to wake you, it is best to 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.  
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 where a fire might start and block  
your escape from the house.  
BEDROOM  
Next to or directly above heaters or air conditioning  
vents, windows, wall vents etc. that can change the direc-  
tion of airflow.  
Positioning your Smoke Alarm  
·
·
In very high or awkward areas where it may be difficult to  
reach the alarm (for testing, battery replacement etc).  
Figure 3: Multi Storey Dwelling  
(a) Single Storey Dwelling.  
Locate unit at least 1.5m (5 feet) and route wiring at least 1m  
(3 feet) away from fluorescent light fittings as electricial  
“noise” and/or flickering may affect the unit.  
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)  
Figure 4  
Figure 5  
IDEAL IN CENTRE OF CEILING  
·
·
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 prevent  
smoke from entering the chamber.  
90cm  
DE AD AIR S PACE S  
Do not locate in insect infested areas. Small insects get-  
ting in to the chamber can cause intermittent alarms.  
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.

and the test button on the first unit will flash about once a sec-  
ond. Check all the other units similarly.  
(b) FIRE SAFETY HINTS  
·
Smoke Alarms will not detect fire 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.  
Getting your Smoke Alarm Serviced  
Store petrol and other flammable materials in proper containers.  
If your Smoke Alarm fails to work after you have read the sec-  
tions on “Connecting the battery” and “Looking after your Smoke  
Alarm” contact Customer Assistance at the nearest address  
given at the end of this leaflet. If it needs to be returned for repair  
or replacement put it in a padded box (battery disconnected)  
and send it to “Customer Assistance and Information” at the  
nearest address given on the Smoke Alarm or in this leaflet.  
State the nature of the fault, where the Smoke Alarm was pur-  
chased and the date of purchase.  
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.  
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.  
·
·
The Smoke Alarm may not be heard.  
Important Safeguards  
Do not overload electrical circuits.  
Keep matches away from children.  
A smoke alarm may not wake a person who has taken drugs  
or alcohol.  
When using household protective devices, basic safety precau-  
tions should always be followed, including those listed below:  
·
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.  
Never smoke in bed. In rooms where you do smoke, always  
check under cushions for smoldering cigarettes and ashes.  
Five Year Product Guarantee (excluding battery)  
·
·
Please read all instructions.  
EI Co. Ltd. guarantees this product (excluding battery) against  
any defects that are due to faulty material or workmanship for a  
five year period after the original date of consumer purchase or  
receipt as a gift. This guarantee does not include damage to the  
product resulting from accident or misuse. It also excludes inci-  
dental and consequential damages. If the product should be-  
come defective within the warranty period, we will replace it free  
of charge. (see “Getting Your Smoke Alarm Serviced”)  
Rehearse emergency escape plans so everyone at home  
knows what to do in case the alarm sounds.  
Service central heating systems regularly.  
·
·
·
For replacement batteries, refer to label inside smoke  
alarm.  
Be sure all electrical appliances and tools have a recognised ap-  
proval label.  
·
Smoke Alarms don’t last indefinitely. The manufacturer rec-  
ommends replacement after 10 years as a precaution.  
NOTE: Constant exposure to high or freezing temperatures  
or high humidity may reduce the life of the batteries.  
This device cannot protect all persons at all times. It may not  
protect against the three most common causes of fatal fires:  
Do not disconnect battery to stop alarm sounding. (Fanning  
vigorously with a newspaper or similar will remove nuisance  
smoke from the Smoke Alarm and stop it sounding.)  
Planning your Escape for when the Alarm  
goes off  
1. Smoking in bed.  
Do not interfere with the product or attempt to tamper with it.  
This will invalidate the guarantee.  
2. Leaving children at home alone.  
3. Cleaning with flammable liquids, such as petrol.  
·
·
Do not attempt to recharge or burn batteries, as they may  
explode. Wrap in paper and discard normally.  
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.

When removing battery, handle carefully to avoid possible  
eye damage or skin irritation if battery has leaked or cor-  
roded.  
Further information can be obtained from the Home Office Publi-  
cation entitled “Smoke Detectors in the Home” (FB2) or from  
your local fire prevention officer.

To maintain sensitivity to smoke, do not paint or cover  
smoke alarm in any manner; do not permit any accumula-  
tion of cobwebs, dust or grease.  
What is the best Smoke Alarm - Optical or  
Ion ?  
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.)  
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.  
Both types respond in all standard fires but each type may re-  
spond faster to particular fires as shown. The EI company  
manufactures two complementary 9 volt Smoke Alarms , Opti-  
cal Smoke Alarm EI105C and Ion Smoke Alarm EI100C. For  
dual protection install each type.

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.  
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.  
Smoke Alarms are not a substitute for insurance. The sup-  
plier or manufacturer is not your insurer.  
Ion Sensor  
Best for fast flaming fires  
- small smoke particles  
Optical Sensor  
Best for slow smouldering fires  
- large smoke particles  
(b) Limitations of Smoke Alarms  
Smoke Alarms have significantly helped to reduce the number  
of fire fatalaties in countries where they are widely installed.  
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.  
However independent authorities have stated that they may be  
ineffective in some circumstances. There are a number of rea-  
sons for this:  
4. Call the Fire Brigade from a neigh-  
bour’s house. Remember to give your  
name and address.  
·
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.  
5. NEVER re-enter a burning house.

IMPORTANT NOTICE  
WARNING  
DUST & INSECT CONTAMINATION  
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.  
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 the effect of dust and  
insect contamination, and therefore, to prolong the life  
of the Smoke Alarm 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.  
(Excessive dust & debris from building work  
can contaminate the smoke chamber and  
cause problems).  
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 replace-  
ment. 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.  
An installed smoke alarm must be removed or cov-  
ered fully (with a plastic bag or similar) before reno-  
vations begin.  
B10274-2  
© EI Electronics 2001  
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 detection makes it less  
vulnerable to the effects of dust or insect contamination.
