MOUNTING
Detectors should be mounted mainly near places particularly exposed to the presence of carbon monoxide, which is produced due to the
combustion of fuels such as: gas, wood, coal. In order to avoid false alarms it is recommended to keep a 2 meter distance from the possible
carbon monoxide sources. Sensors should be mounted at a height of 150 cm from the ground. In order to provide an optimum protection,
sensors should be also mounted in closed rooms where the household members stay for a longer time, e.g. especially in bedrooms. In
multi-storey buildings it is advised to mount at least one sensor per each floor. Detectors should not be installed both in the so called blind
spaces (e.g. a niche covered by furniture or curtains or in the gable of the roof, etc.) and in places where their operation will be affected by
the direct supply of fresh air (e.g. near doors, windows, ventilation grilles, fans). Also, these devices should not be placed in areas exposed
to dust, dirt, aerosols and household chemicals that can permanently damage the detector.
In order to mount the device it is required to:
• remove the back cover in the counter-clockwise direction to release the clips
• check if the batteries are properly mounted, in case mount new ones (3 batteries AA type)
• screw the back cover to the wall by means of the attached screws and mount the device on it by turning it in the clockwise direction until
you can hear a click
FUNCTIONS
First activation
After batteries are properly mounted, the device switches on the LCD screen, the red LED and emits a single sound signal. Next press the
„TEST” button to activate the testing procedure. In case the test has been successful, the device switches off the LCD screen and switches
to the operation mode that is signalled every 10 seconds by the green LED flash.
Test procedure
After pressing the TEST button, the device performs the test procedure by checking the sensor’s efficiency. The display shows „000” and
every 5 seconds a repeated sound signal is emitted and the red LED remains switched on. After 30 seconds the device should return to
the operation mode signalled by switching off the LCD screen and a flashing green LED (every 10 seconds). It means the test procedure
has been successful. Device testing is recommended at least once a month.
Alarm
If a sensor detects a dangerous carbon monoxide level, it will automatically switch on the LCD screen showing the carbon monoxide
level and will emit a sound alarm every 5 seconds, whereas the red LED will flash. In case an alarm occurs, it is required to ventilate
immediately the particular room and to leave it at once. It is also important to notify the relevant services to check the cause of excessive
concentration of carbon monoxide.
Mute alarm function
In case the alarm is activated, press the TEST button to mute the sound signal for a few minutes. If the dangerous carbon monoxide level
is still so high, the alarm will be activated again.
Battery discharge signalling
In case the battery charge level is low the display shows the following message „Lb” and starts emitting a single sound signal with a
flashing red LED every 20 seconds. It is required to change the battery immediately.
Device failure signalling.
The device is equipped with an auto-diagnostic system, which shows „Err” on the LCD screen in case of a sensor failure occurrence.
Additionally, a double sound signal is emitted and the yellow LED starts flashing. The alarm is repeated every 5 seconds. The device
failure requires its user to contact the service.
Signalling the electro-chemical sensor’s end of life
After the lifetime of an electrochemical sensor is exceeded, the display shows „End” and, additionally, a triple sound signal is emitted
every 50 seconds with a flashing yellow LED. This means the end of life of the sensor and the necessity to replace it with a new one.
Carbon monoxide, commonly referred to as coal smoke, is a highly toxic, colourless and odourless gas easily spreading in the air. It is
produced in the process of an incomplete combustion of many fuels such as wood, fuel oil, gas, gasoline, kerosene, propane, coal and oil.
Incomplete combustion is caused by a lower oxygen level necessary for a complete combustion. The above may be due to a lack of fresh
(external) air supply to the device where the combustion takes place or due to contamination, usage or improper adjustment of the gas
burner or too early closure of the fire box or oven. The following can also be the causes of carbon monoxide accumulation: clogged chim-
neys and clogged ventilation ducts. The above is especially dangerous in homes where windows are tightly closed or sealed for winter. The
danger of asphyxiation is due to the fact that carbon monoxide is an undetectable gas to humans because it is colourless and odourless.
It enters the body through the respiratory system and next it is absorbed into the bloodstream. In the human’s respiratory system, carbon
monoxide is assimilated with haemoglobin 210 times faster than oxygen blocking the flow of oxygen to the body. The above results in a
serious threat to human health and life. It prevents the proper distribution of oxygen in the blood and causes damage to brain and other
organs. The consequence of an acute poisoning can be an irreversible damage to the central nervous system, coronary insufficiency, heart
attack or even death. That is why, it is so important to mount carbon monoxide detectors in lodgings, to control regularly carbon monoxide
generating equipment (stoves, boilers, gas water heaters, etc.) and to control ventilation ducts.
In case of an alarm it is required to:
• Ventilate the particular room by opening the windows and doors
• immediately leave the room, although the alarm is switched off, it is important to define the cause of its occurrence by controlling
the condition and the flow of ventilating ducts, the condition of the heating units and eventually notify the relevant services (e.g.
fire-brigade, gas-works),
• in case any of the household members has a poisoning symptom (headaches and dizziness, nausea) it is required to immediately
notify the ambulance.
Maintenance and usage remarks
• Clean the device regularly, keep clean the sensor’s air inlet - mount the device in places meeting the requirements regarding
temperature and humidity,
• do not cover the device with paint while painting the room,
• do not spray the cleaners directly on the device,
• do not allow to flood the sensor,
• mount the sensor according to the requirements,
• it is absolutely required to replace the sensor in case the sensor’s end of life.
It is important to take into account that carbon monoxide sensors perfectly raise the protection of
household members, but they do not provide 100% certainty of carbon monoxide fumes detection due
to a possibility of a device failure, battery discharge and the impact of external factors on the sensor.
Therefore, it is required to systematically test the sensor’s efficiency (in accordance with this manual
instruction) and the heating units (stoves, cookers) to minimize the risk of occurrence of a dangerous
carbon monoxide level in the air.
Before mounting the sensor, read this manual instruction first.
