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.
!
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
