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: We suggest the use of an incense
stick or cigarette as the way in which
these products burn produces a readable
localized amount of CO. A readable level
of carbon monoxide will not be given off
by other sources of smoke, for example an
extinguished candle or match.

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

NOTE: If the level of CO in the sensor
doesn’t reach 50ppm then the Sensor Test
