Your CO alarm monitors levels of CO as parts per million
(ppm) in the air surrounding the detector.
35ppm
The maximum allowable concentration for
continuous exposure for healthy adults in
any 8 hour period, as recommended by the
Occupational Safety & Health Administration
200ppm Slight headache, fatigue, dizziness, nausea
after 2 - 3 hours.
400ppm Frontal headaches within 1 - 2 hours, life
threatening after 3 hours.
800ppm Dizziness, nausea & convulsions within 45
minutes. Unconsciousness within 2 hours.
Death within 2 - 3 hours.
If you suspect CO may be affecting you, open the doors
& windows to ventilate. Turn off your appliances & leave
the premises.
Common Sources of CO
• Oil & gas boilers
• Portable generators
• Oil or solid fuel cookers
•
Gas or paraffin heaters
• Barbecues
• Clogged chimneys
•
Wood or gas fireplaces
• Cigarette smoke
• Gas appliances

This CO alarm should not be seen as a substitute for the
proper installation, use & maintenance of fuel-burning
appliances (including appropriate ventilation & exhaust
systems), nor the sweeping of chimneys.
What To Do In The Event Of An Alarm
WARNING:
A loud alarm is a warning that potentially lethal
levels of carbon monoxide are present. Never ignore this
alarm, further exposure can be fatal. Immediately check
residents for symptoms of CO poisoning. Contact the
proper authorities to resolve all CO problems.
• Keep calm; open doors & windows to ventilate the
property.
• Stop using all fuel-burning appliances & if possible,
turn them off.
• Evacuate the property, leaving doors & windows open.
• Ring your fuel supplier on their emergency number.

__________________________________________
• Depending on the level of CO detected, it can take
up to 10 minutes to clear the sensor and the alarm to
stop. Do not re-enter the property until the alarm has
stopped.
• Get medical help immediately for anyone suffering
the effects of CO poisoning (headache, nausea), and
advise that carbon monoxide poisoning is suspected.
• Do not use appliances again until they have been
checked by an expert.
Understanding the Product’s Indicators
The higher the concentration of CO detected, the quicker
the alarm will respond. When sufficient CO is detected a
loud audible signal of 4 chirps repeated (85 dB at 1m/3
feet) will sound & the Alarm LED will flash red every 5
seconds. The alarm will sound:
Between 60 & 90 mins when exposed to 50ppm of CO.
Between 10 & 40 mins when exposed to 100ppm of CO.
Within 3 mins when exposed to 300ppm or more of CO.
Fault / End of Life Signal:
The alarm constantly checks the settings of its sensor &
circuitry. If the battery power is low, the alarm will chirp
once per minute & the Fault LED will flash amber.
If the amber LED flashes at a separate time from the chirp,
a fault is indicated.
IMPORTANT:
If you experience an error condition or low
battery warning and the product is still within warranty
then contact Customer Support. If the product is no longer
in warranty replace immediately.
