Selecting location
· 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
