SAFETY & SECURITY
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 be performed annually.
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.
Read all steps thoroughly before attempting
to test the sensor.
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.
Step 3 Light a cigarette or an incense stick
using a match or lighter. If using an
incense stick be sure to blow out the
flame so that the incense stick is
smouldering. Extinguish the lighter,
or put out the match and place it into
a dish of water.
Step 4 Turn the detector on its side so that
the vents on the right hand side of
the detector are pointing downwards.
Hold the burning cigarette or incense
stick 15cm (6 inches) below the
detector, so that the smoke enters
the vents on the side of the detector.
An increase in the localised carbon
monoxide level with the sensor to
more than 50ppm will cause the
sounder to sound for one cycle of
four loud beeps and the Fault LED to
illuminate yellow for a short time.
This is the end of the test. The Fault
LED will no longer flash yellow and
the detector will go back to normal
operating mode ie. the Power LED
will flash green once every minute (It
may take up to two minutes of
exposure to the smoke for the
localised level of carbon monoxide
within the sensor to reach over
50ppm). Now move the source of CO
away from the detector as the test is
finished.
Step 5 After step 4, put out the incense stick
or cigarette by placing it into a dish of
water. Ensure that all flames have
been extinguished.
Note: If the localised carbon monoxide level
within the sensor does not reach 50ppm
during the test, the sensor test will stop
automatically after 3 minutes.
