· In every room in which people spend long periods of time and from which they
could not hear an alarm from another part of the building.
Minimum installation
If the number of alarms is limited or there are combustion devices in more than
one room, the following criteria should be taken into account when installing the
alarms:
· The alarms should be installed in rooms which contain a device without a smoke
outlet or with an open smoke outlet.
· The alarms should be installed in rooms in which occupants spend the most
amount of time.
Where in the room?
Carbon monoxide (CO) has almost the same density as air and therefore distributes
itself uniformly in space. Consider the following points when positioning the CO
alarm:
It is impossible to give exact instructions on the correct arrangement of an alarm
which apply for all types of rooms and their use. The following points should be
taken into account when choosing the optimal location for each corresponding
situation.
Alarm located in the same room as a combustion device
When CO escapes from a combustion point, the heat initially rises. This is why you
should install alarms as high as possible on a free wall in rooms with combustion
devices, while considering the following points:
· The alarm should be assembled on a free wall, at least 200 mm below the ceiling.
· Install the alarm at a height at which you can reach it without tools and at which
you can see all alarm displays. (Between chest and head)
· The alarm should be at a horizontal distance of 1 to 3 m from the possible source
of carbon monoxide.
· If the room is divided, the alarm should be on the same side of the division as

the possible source of carbon monoxide.
· In rooms with slanted ceilings, the carbon monoxide alarms should be installed at
the higher side of the room.
Alarms located in bedrooms and rooms far away from combustion devices
In rooms located far away from combustion devices, the carbon monoxide has
already cooled to room temperature. Due to the fact that CO has nearly the same
density as air, it distributes uniformly in the air.
Consider the following points:
· In bedrooms and in rooms which are located far away from combustion devices,
the devices should be at the breathing level of the occupants (e.g. "desk level" at
the bed-side table in bedrooms and "eye level" in living rooms).
· Make sure there is sufficient spacing to the ceiling as well as to corners and
furnishings (min. 200 mm).
Where alarms should not be installed
· outside (use only possible in closed rooms);
· where they can be blocked (e.g. by furniture);
· on ceilings (only suitable for wall installation);
· next to a door or a window (reliable detection cannot be guaranteed);
· next to an air duct or similar ventilation opening;
· in areas in which the temperature can fall below -10° C and rise over
40° C;
· in rooms that are exposed to large amounts of dust/dirt or grease.
