SAFETY AND SECURITY
45
(i.e. the 6th segment is shown the unit will
sound a loud audible alarm (85 dB at 1m
(3 feet)) and the Alarm LED below the
symbol on the front of the detector will flash
red once every second.
The Alarm will sound
• Between 60 and 90 minutes when exposed
to a minimum of 50ppm of CO.
• Between 10 and 40 minutes when exposed
to a minimum of 100ppm of CO.
• Within 3 minutes when exposed to a
minimum of 300ppm of CO.
Alarm silence
It is possible to temporarily silence the
alarm up to two times if the level of CO that
triggered the alarm is less than 200ppm. After
ventilating the property you can temporarily
silence the alarm by pressing the Test/Mode
button, the alarm will stop and the silence
mode symbol will appear on the screen. The
silence mode will last for up to 3 minutes. If the
CO level remains too high the alarm will trigger
again or if the level of CO rises above 200ppm
then the detector will automatically re-enter
alarm mode. If the level of CO has fallen to a
satisfactory level the silence mode icon will
disappear, the unit will exit alarm mode and
the segments of the bar graph will slowly
disappear as the CO in the sensor clears.
Alarm in absence:
If the Peak level reading symbol is
showing on the screen but there is no full
alarm sound and you are not pressing the
test button, then your detector is warning
that it has detected Carbon Monoxide in your
absence. Immediately vacate the premises and
seek medical attention for anyone suffering the
effects of CO poisoning (headache, nausea).
Treat this as a serious warning. Call a qualified
technician and have the problem investigated
and rectified immediately.
Error signal
The unit continuously checks the set-
tings of its sensor and circuitry. If any of these
settings
are found to be incorrect, the detector will emit
a single chirp once per minute and the display
will show “Err” for error and an error code,cy-
cling between “Err”and the particular
error code.
Low power pack signal
If the power pack becomes low then the de-
tector will emit a single chirp once per minute
and the low power pack icon will flash on the
screen.
! IMPORTANT: A single chirp once per
minute together with an error signal 14 or
low power pack warning does NOT mean
that the detector has detected carbon
monoxide.
If you experience an error condition or low
power pack warning and the product is still
within warranty then contact technical support.
If the product is no longer in warranty replace
immediately!
