CO DETECTOR 36-2932
Carefully read the entire instruction manual before
you place, mount or use your new CO detector.
Save the instructions for future use.
Good to know about carbon
monoxide CO
Carbon monoxide (CO) is an odourless, invisible,
tasteless and very toxic gas. CO effects haeomoglob-
in, by impairing its ability to absorb oxygen. The effect
of CO causes the body acute oxygen starvation. The
following symptons can be caused by CO poisoning.
All family members should be aware of the effects of
the following concentrations of CO in the air:
-
Low concentration (under 200 ppm): Light
headache, nausea, tiredness, cold-like symptoms.
-
Medium concentration (between 200-400 ppm):
Pounding headache, drowsiness, confusion, heart
palpitations. Can be fatal within 3 hours exposure.
-
High concentration (over 400 ppm): Throwing
up, unconsciousness, respiratory distress etc.
Can be fatal after less than 3 hours exposure,
even in seconds, depending on the dosage.
What amount of CO concentration can
damage me or my family?
This is varies very much from person to person. CO
is a poisonous gas and affects people in different
ways. Age, weight, size, general state of health are
some of the factors that have influence. Certain
categories of people; such as, foetuses, infants,
children, elderly and people with heart or lung condi-
tions are always at higher risk.
Your CO warner is calibrated to respond to the fol-
lowing levels of CO (according to EN50291:2001).

The alarm warns through a siren which sends 4
repeated signals, while at the same time the red
control light under the test button blinks 4 times. A
pre-warning takes place at 40 ppm when the red
control light blinks every 8th second.
Where can CO be produced?
CO is produced through the incomplete burning of
fossile fuel such as natural gas, bottled gas, paraffin,
coal, petrol, diesel oil, or wood. Incomplete burn-
ing can occur in all household burning appliances
which use combustion for heating or energy, e.g.
gas ranges, water heaters, radiators, boilers, gas
ovens, fireplaces, pellet burners, portable grills, and
of course in all forms of petrol or oil-driven engines
(e.g. lawn mowers, vehicles etc.)
When functioning normal and well maintained the
use of the above equipment is not dangerous.
Smoke and burning gases are ventilated out through
a chimney or ventilation pipe. Normally there is no
risk of CO with equipment that only uses electricity.
There are always two demands for a burner to func-
tion correctly:
-
Adequate supply of air (oxygen) so that
complete burning is achieved
-
Correct ventilation of the gases
Do not forget to check regularly and maintain all
types of burners!
Example for common risks for CO poisoning
-
Technical problems with equipment, depending
on faults, lack of service or maintenance.
-
Faulty chimney or ventilation pipe which can
have fallen or clogged (e.g. bird nest, snow,
etc.)
-
Faulty ventilation direction of air, so called back
draught.
-
Faulty installation of burner.
-
In equipment which is used regularly; for shorter
periods of time, or by different people.
-
Chimneys of the wrong size etc.
-
Garden grills which are used indoors.
Recommended placement of
your CO detector
Different buildings have dif-
ferent layouts. The following
is some general advice to
help detect CO early on –
and at the same time reduce
the risk of false alarm. The
best protection is obtained
if you place a CO detector
in or near every room which
has a burner, in rooms that
are often frequented and in the bedroom. Always
place one CO detector per floor! For increased safety
several CO detectors can be interconnected.
If you have
several burners
, but only
one
CO detec-
tor
you should in the first place think of the following:
1. if there is one burner in your bedroom install
your CO detector there
2. if there is one burner in any room where you
spend a lot of time, e.g. TV room, install your
CO detector there
3. if you live in a small house (one room) with a
kitchenette install the detector as far away as
possible from the range, however as close as
possible to the bed.
4. if the burner is in a special room e.g. boiler room
place the detector just outside this room, so that
it is easier for you to hear the alarm signal
Your CO detector can either be placed on a wall or
on the ceiling. It should be possible for you to be
able to maintain, test and hear the detector. Always
remember the following:
Placement of CO detector in the
same room
as the
burner:
On wall:
-
Mounted high on the wall
-
Higher than any door or
window-frame
-
At least 15 cm from the ceiling
On ceiling:
-
At least 30 cm from any wall
-
For sloping ceiling mount 30 cm
from the highest point.
In both cases:
-
If the room has a separate lower level mount the
detector on the same side of the burner.
-
Mount the CO detector at least 150-200 cm
distance from the burner.
Placement of CO detector in bedroom, or
another
room
other than the burner:
-
Mount the detector close to where you spend
time and breathe.
Never place the CO detector in the follow-
ing places
-
Outdoors, or in a wet or humid environment
-
Close to any type of exhaust outlet
-
Behind a curtain, closet or cornice
-
Directly above the dish counter, oven or range
-
Next to any door, window, weathering vent or
such where there is a risk for draughts.
-
Next to a ventilation canal or fan
-
Where the temperature can drop below 10 °C or
rise above 40 °C
-
Where humidity is less than 30% or higher than
90% relative humidity
-
Where dirt or dust can affect the detector’s sensor
-
Close to strong chemicals, or detergents which
can affect the detector’s sensor
Note!
The CO detector is used only to detect CO
gas. To detect other gases e.g. bottled gas or natu-
ral gas you should use an appropriate gas detector;
and for protection against fire, you should use a
normal smoke detector. Your CO detector is con-
structed to warn normal healthy people of danger-
ous concentration of CO gas. For people with medi-
cal problems this sensitivity can in certain cases
be too low. In that case consult a doctor or other
person with medical knowledge.
