a For both wall and ceiling mounted
apparatus the following applies:
•
The apparatus should be at a horizontal
distance of between 1m and 3m from
the potential source
•
If there is a partition in a room, the
apparatus should be located on the
same side of the partition as the
potential source
•
Carbon Monoxide detectors in rooms
with sloped ceilings should be located at
the high side of the room
b In addition to the previous points the
following must be observed:
If the apparatus is located on a wall:
•
it should be located close to the ceiling;
•
it should be located at a height greater
than the height of any door or window;
•
it should be at least 150mm from the
ceiling.
If the apparatus is located on the ceiling:
•
it should be at least 300mm from any
wall and any ceiling obstruction e.g.
light fittings.
Apparatus located in sleeping rooms and in
rooms remote from a fuel burning appliance:
•
Apparatus located in sleeping rooms or
located in rooms remote from the fuel-
burning appliance should be located
relatively close to the breathing zone of
the occupants
Where not to put the detector
The apparatus should not be installed:
•
In an enclosed space (for example in a
cupboard or behind a curtain)
•
Where it can be obstructed (for example
by furniture)
•
Directly above a sink
•
Next to a door or window
•
Next to an extractor fan
•
Next to an air vent or other similar
ventilation openings
•
In an area where the temperature may
drop below -10°C or exceed 40°C
•
Where dirt and dust may block the sensor
•
In a damp or humid location (for example
in a bathroom)
•
Less than 1m/3 feet from any appliance
•
Within 1m (3 feet) of mobile phones
Caravans
Caravans may have additional risks of carbon
monoxide ingress through air vents due
to the nearby presence of other vehicles,
engines, generators or barbecues, however
this does not change the basic guidance
on location of the alarm. Caravans should
be fitted with an alarm in the same room
as any combustion appliance(s), located
in accordance with previous advice in this
section. If the caravan has a single living
space which incorporates the sleeping
accommodation, it can be considered to
be equivalent to a bedsit, and a single
alarm is sufficient. However, any sleeping
accommodation which is in a separate room
