Functional principle and features
According to EN 50291, the COWM300 ABUS CO alarm is
designed and approved exclusively for detecting CO (carbon
monoxide) in private homes.
Application in industrial facilities, offices, boats, caravans or
mobile homes is therefore not permitted.

Functional principle and features
14
The battery-operated ABUS CO alarm (COWM300) detects carbon
monoxide (CO) in even low concentrations, then gives off an acoustic as
well as optical signal.
The purpose of the CO alarm is to protect persons against the acute
effects of carbon monoxide. However, it cannot prevent the chronic affects
of carbon monoxide exposure or offer persons with special risks complete
safety.
The CO alarm is not a substitute for smoke, fire or other
alarms.
It does not detect smoke, heat or other gases.
In addition, the electrochemical sensor can only detect CO on
time in a limited area (max. 60 m², depending on the
environmental conditions).

Formation & dangers from carbon monoxide
15
Formation & dangers from carbon monoxide
Poisonous effect
Carbon monoxide (CO) is a colourless, odourless, non-
irritating gas which can quickly become a deadly threat.
Carbon monoxide bonds to the pigment of the red blood cells,
thereby preventing the transport of oxygen, which can lead to
unconsciousness and death by suffocation.
High concentrations of CO can lead to dead in just a few
minutes.

Formation & dangers from carbon monoxide
16
Typical symptoms of poisoning
Low
CO concentration
Mild headaches, nausea, tiredness, flu-like symptoms
Medium
CO concentration
Bad headaches, racing heart, vomiting
High
CO concentration
Cramps, confusion, unconsciousness, cardiac
arrhythmia
Please note that the symptoms can occur earlier with
children, pregnant women, senior citizens and persons with
respiratory or heart diseases and even low CO levels could
cause organ damage in unborn children.

Formation & dangers of carbon monoxide
17
Sources of carbon monoxide & preventative measures
Carbon monoxide is created, among others, during
incomplete combustion processes (e.g. defective floor
heating or clogged smoke outlets).
Installing a CO alarm is not a substitute for the proper
installation, use and maintenance of fuel-burning devices
including related ventilation and exhaust gas systems.
Have such devices/systems installed only by qualified
persons. Acquire the devices/systems in perfect technical
condition and have them regularly inspected.
Make sure that ovens, chimneys and the like are kept clean
at all times.
Never operate barbecues, deck ovens, heating devices or
other devices intended for use outside inside closed rooms.

Behaviour in case of alarm
18
Behaviour in case of alarm
When a carbon monoxide alarm sends out a signal, take the following measures
in the specified order:
(1) Keep calm and open all doors and windows to increase the
rate of ventilation. Stop using all combustion devices and
make sure that they are switched off.
(2) Press the Test/Reset button to switch off the alarm signal.
Do not enter the affected area until the CO concentration
has fallen below the critical level.
(3) If the CO concentration is still critical after the muting time of
5 min, the CO alarm goes off again. (For values over 999°
ppm, the alarm signal cannot be switched off!)
(4) Leave the building in particular when the CO level is high or
when the source cannot be instantly detected and alert
occupants, if applicable.
(5) Call the fire service/rescue worker immediately. Follow their
instructions. Inform them that you assume carbon monoxide
it being inhaled.
(6) Do not use the affected combustion device until the cause
of CO emission has been removed by a professional.

Behaviour in case of alarm | Selecting location
19
(7) Check the functionality of the CO alarm after it has triggered
(using Test/Reset button) and replace the batteries if
necessary.
Selecting location
General
The design and spacial distribution of residential buildings as well as the number,
type and location of carbon monoxide sources can vary greatly. However, there
are general instructions concerning where the device should and should not be
installed to keep the risk of false alarms as low as possible.

Selecting location
20
Which room?
Installation for optimum safety:
In every room that contains a combustion device.
In every room that is used as a sleeping area.
In every hallway per floor.
In every room in which people spend long periods of time and from
which they could not hear an alarm from another part of the building.
