SENSOR TEST
CAUTION: Sensor testing should only be
performed by a responsible adult. This
test should only be performed once a month.
Excessive testing will shorten the life of the
power pack.
NOTE: Aerosol CO test kits may be used
in order to avoid having to burn incense
sticks or cigarettes. However we recommend
that incense sticks are used as they are
cheap and readily available. A readable level
of carbon monoxide will not be given off
by other sources of smoke, for example an
extinguished candle or match.
Step 1: If the alarm is wall mounted unhook it
from the fixing screws.
Step 2: Hold the Test/Mode button down
until the spanner icon appears in the
bottom left hand corner of the screen
and the bar graph ‘scans’ from left
to right. This indicates the alarm is in
sensor test mode where the sampling
rate of the sensor has increased and the
alarm can be tested using a known source
of CO.
Step 3: Light an incense stick or cigarette
using a match or lighter. Extinguish the
lighter, or put out the match and place it into
a dish of water.
Step 4: Hold the incense stick or burning
cigarette 15cm (6 inches) below the detector,
so that the smoke goes into the holes at the
bottom of the detector. As the smoke gets
into the alarm the display will show the
amount of CO being detected. When the
level of CO in the sensor reaches 50ppm the
alarm will sound a single alarm cycle, this
confirms that the sensor is working correctly
and is the end of the sensor test. The alarm
will return to normal standby mode.
Step 5: 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 level of CO in the sensor
doesn’t reach 50ppm then the Sensor Test
mode will time out and finish automatically
after 3 minutes. Even if the level doesn’t
reach 50ppm, as long as the display shows a
reading of CO then you can be confident that
