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 consi-
dering 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 com-
bustion 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
Selecting location Behaviour in case of alarm, Selecting location
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.
Installation and start-up
The following two variants are possible for operating the CO
alarm:
Wall installation
Take the following steps in the specified order to install the
alarm on the wall:
1. Hold the mounting base in a horizontal position at the
desired location and mark the drill holes.
2. Drill the holes with a suitable power drill ø 5 mm at the
previously marked locations.
