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 eects 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 eects. 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 o, 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, paran, 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 insuciently
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.

Concentration Symptoms
100 ppm No symptoms – no danger
200 ppm Slight headaches
400 ppm Strong headaches after 1–2 hours
800 ppm Strong headaches after 45 minutes, nausea, faintness and unconsciousness
after 2 hours
1 000 ppm Dangerous concentration – unconsciousness after 1 hour
1 600 ppm Nausea, strong headaches and dizziness after 20 minutes
3 200 ppm Nausea, strong headaches and dizziness after 5–10 minutes, unconsciousness
after 30 minutes
6 400 ppm Nausea, strong headaches and dizziness after 1–2 minutes, unconsciousness
after 10 –15 minutes
12 800 ppm Instant unconsciousness, risk of death after 1–2 minutes
All persons residing on the premises should be made aware of the symptoms of CO poisoning!
The device for monitoring CO concentration activates the alarm if it detects a certain concentration
of CO for a certain duration:
CO concentration in ppm Alarm activation
≥30 120 min
≥50 60 to 90 min
≥100 10 to 40 min
≥300 within 3 min
Installation
The installation must be performed by a qualied person. Ideally, the warning device should be located
in every room with a fuel-burning device. It is strongly recommended to also install warning devices
in bedrooms and rooms where you spend a lot of time.
If the warning device is installed in the same room as the fuel-burning device:
• Place the warning device in the vicinity of the ceiling and above the level of the top edge of
windows and doors.
• When installing onto the ceiling, the warning device must be located at least 30 cm away from
walls.
When installing onto a wall, the warning device must be located at least 15 cm from the ceiling and
180 cm from the oor.
Do not install the warning device in rooms with vaulted ceilings, gable roof etc.
Do not install the warning device in the vicinity of ventilation openings or windows/doors that lead
outside.
Do not install the warning device behind curtains/furniture; doing so would decrease the ability of
the device to correctly detect the CO level.
Do not install the warning device in an area with temperature lower than -10 °C or higher than 40 °C.
If possible, install the warning device approximately at eye level for ease of checking the LED indicators.
If you are only installing one warning device, place it in the vicinity of the bedroom (not in the
basement etc.).
Make sure that you can hear all the installed warning devices from the room where you sleep.
The warning device must be located at a distance of 1 m to 3 m horizontally from the nearest edge
of a potential CO source.
5
The ventilation openings of the warning device must not be covered up.
Do not spray aerosol agents in the vicinity or onto the warning device.
Do not paint the warning device.
If the warning device is located in a room without a fuel-burning device, it must be located in the
vicinity of the breathing area of the persons residing in the room. In open-plan rooms where people both
sleep and spend their time, such as one-room ats, caravans or boats, the device must be located as
far away as possible from cookers while also being in the vicinity of the space reserved for sleeping.
Location meeting the requirements set by NFPA (US National Fire Protection Association)
Suggestions for the placement of additional CO alarms in the building
Installing the Device onto a Wall
(see Fig. 2)
1 – Openings for hanging onto a wall
Drill two holes (ø 5 mm) into the wall; the distance between the holes should be 52 mm.
Insert the wall plugs provided, then insert the screws provided into the wall plugs.
Insert the screws so that ca. 5 mm protrude out of the wall.
Put batteries into the alarm and test its functioning, see Test Mode.
If the alarm works, close the battery cover and t the two openings on the battery cover onto the
protruding screws.
COMMISSIONING
(see Fig. 3)
Insert batteries (2× 1.5 V AA) into the battery compartment on the back. Use alkaline batteries only;
do not use rechargeable 1.2 V batteries (due to their lower voltage).
Warning:
The battery cover cannot be shut unless both batteries are in place! The closing of the battery
cover is prevented by two metal bumps underneath the battery compartment. If you wish to
mount the device onto a wall, batteries must always be inserted and the battery cover closed.
After inserting batteries, you will hear a beep and all three diodes (POWER, FAULT, ALARM) will ash
at the same time. The green POWER LED will ash 1× every 60 seconds after battery insertion; the
device is calibrating. After 60 seconds, the GREEN POWER LED will ash 1× every 40 seconds to
indicate that the batteries are working.
TEST MODE
You can test the functioning of the alarm whenever needed or after every change of batteries.
Press and hold the TEST/SILENCE button. The alarm will simultaneously beep and ash its RED
ALARM LED 4× every 5 seconds.
Release the TEST/SILENCE button; the alarm is ready for use.
