way in which these products burn means
the smoke given off contains a detectable
localised amount of carbon monoxide.
Alternative sources of smoke, for example
an extinguished candle or match, will not
contain sufficient levels of carbon monoxide
to obtain a response from the detector during
this test. Please note your CO detector will not
detect smoke.
CAUTION: Sensor testing should only
be performed by a responsible adult.
This test should only be performed once a
month. Excessive testing will cause the life
of the power pack to be shortened.
NOTE: CO test kits may be used in
order to avoid having to burn cigarettes,
incense sticks etc. However we recommend
that incense sticks are used as they are cheap
and readily available.
