Effects of carbon monoxide poisoning
Carbon monoxide binds the haemoglobin in the blood which reduces
the oxygen transported in the body. Highly concentrated CO leads to
death within minutes.
35 ppm
The highest permissible CO value over a period of 8
hours
200 ppm
Light headache, fatigue, dizziness, nausea after 2 to 3
hours
400 ppm
Headache in the area of the forehead within 1 to 2
hours, risk of death after 3 hours
800 ppm
Dizziness, nausea and convulsions within 45 minutes,
loss of consciousness within 2 hours, death within 2 to 3
hours
1600 ppm
Headaches, dizziness and nausea within 20 minutes,
death within 1 hour
6400 ppm
Headaches, dizziness and nausea within 1 to 2
minutes, death within 10 to 15 minutes
Note:
Indication shows max. 999ppm!
Rooms in which a carbon monoxide
alarm must be installed
Ideally, a carbon monoxide alarm should be installed in every room
with a combustion device or where a flue/chimney passes through. If
there are combustion devices in more than one room, however, and
there are only a limited number of alarms or just one alarm available,
the following points should be taken into account in the selection of
the best location:
!
If there is a combustion device in a room in which you sleep, you
should install an alarm in this room.
!
If there is a combustion device in the room in which you spend a lot
of your time, e.g. the living room, you should install an alarm in this
room.
!
In a 1-room apartment, the alarm should be installed as far away as
possible from the cooking facilities but close to the sleeping area.
!
If there is a combustion device in a room which is normally not used
(e.g. boiler room), you should install a carbon monoxide alarm
directly outside this room so that the alarm can be heard more
easily. Alternatively, an external alarm siren can be connected to the
alarm's switching output.
Placement
The CO alarm is designed to be wall-mounted.
The installation location must be selected in accordance with
the following criteria:
When the CO alarm is installed in the room where there is a
combustion device:
!
The alarm should be installed close to the ceiling but no closer than
150 mm from the ceiling.
20 -
GB
!
The alarm should be placed at a height above that of all doors and
windows.
!
The carbon monoxide alarm should be placed at a distance which,
measured horizontally, is between 1 m and 3 m from the possible
source.
!
If there is a partition in a room, the detector should be on the same
side of the partition as the possible source.
!
In rooms with slanted ceilings, the CO alarm should be installed on
the higher side of the room.
When the CO alarm is installed in bedrooms and in rooms
which are far away from a combustion device:
!
The carbon monoxide alarm should be installed at a height of
1.5 m above floor level.
The following locations are not suitable installation
sites:
!
Outside of buildings, e.g. for the monitoring of open gas-bottle
crates
!
Separated areas (e.g. closet interiors or behind curtains) which
could, in the event of a gas leak, prevent the alarm from triggering
!
Next to a door or window
!
In air currents from fans (ventilation, air-conditioning, etc.)
!
Close to an air vent (e.g. extraction hood) or other similar
equipment Ventilation openings
!
Areas in which the temperature can fall below -10° C or rise above
+40° C
!
Damp or wet rooms such as bathrooms and showers where the
relative humidity can rise above 95%
!
Directly next to a cooking stove
!
Directly above cooking facilities
!
Directly above a drain or a basin
!
Areas where dirt and dust can clog the sensor
!
In rooms with potentially explosive atmospheres
The alarm must not be used outdoors!
Installation
Make sure that the voltage is disconnected during installation
and when connecting the power supply!
Two screws are used to fasten the alarm to the wall or selected
location. Use the enclosed screws. Both the assembly holes and the
connection terminals are under a cover plate. The cover plate is
attached simply with two pins and can be lifted off carefully without
the need for tools.
Make absolutely sure to install the alarm at the height
specified in the chapter entitled 'Placement'!
