GB | CO alarm
Warning device (alarm) for monitoring the concentration of the poisonous gas carbon monoxide (CO)
This manual contains important safety information regarding the installation and operation of the
warning device. Read the manual carefully and store it in a safe place for future use or for when the
device is passed on to another user.
Warning
The installation of a warning device (alarm) for monitoring CO concentration is not a substitute for
correct installation, use and maintenance of fuel-burning devices, including proper ventilation and
exhaust systems. This warning device for monitoring CO concentration is designed for protecting
persons against the acute effects of short-term exposure to carbon monoxide, but cannot fully protect
persons with particular health conditions. When in doubt, consult your doctor. Long-term exposure to
low concentrations of CO (>10 ppm) can cause chronic effects. When in doubt, consult your doctor.
The device is only used to detect carbon monoxide (CO), not any other gases. If you are unsure what
caused the alarm to go off, always assume the alarm was triggered by dangerous levels of carbon
monoxide and evacuate the inhabitants.

What Is Carbon Monoxide (CO)
Carbon monoxide (CO) is an odourless, invisible, highly poisonous gas. It is generated through incom-
plete combustion of fuels, such as wood, wooden coal, coal, fuel oil, paraffin, gasoline, natural gas,
propane, butane, etc., and from cigarette smoke. A dangerous concentration of CO can form if the
fuel-burning device is faulty or not properly maintained, if the fuel is blocked or the room insufficiently
ventilated. The seriousness of poisoning from CO inhalation depends on the concentration (listed as
number of particles per million, ppm) and the duration of exposure.
