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, see page 3). Treat this as a serious
warning. Call a qualified technician and
have the problem investigated and rectified
immediately. For usefull contact numbers
see page 17.
Error signal:
The unit continuously checks the settings 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,cycling between “Err”and the particular
error code.
Low power pack signal:
If the power pack becomes low then
the detector 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 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
