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
annually
. Excessive
testing will cause the life of the power pack to be shortened.
NOTE:
Aerosol CO 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.
• Read all steps thoroughly before attempting the sensor test
Step 1
If the detector is wall or ceiling mounted unhook
the detector from the screws.
Step 2
Cover the sounder vents with one hand. Press and
hold the Test/Reset button down with your thumb/
finger until the Fault LED illuminates yellow and
the sounder sounds for a second time (this should
happen after around 5 seconds). Release the
Test/Reset button. Upon releasing the Test/Reset
button the Fault LED will flash yellow once every
second. This indicates that the sampling rate of
the detector has increased and can be tested
using a known source of CO.
