Carbon monoxide sensor

Since the beginning of 2018, the installation of a carbon monoxide sensor has become mandatory.

In the following text, we will provide more detailed information about the homes where it is required. A carbon monoxide detector must be installed in all dwellings that have a gas appliance connected to a chimney, primarily gas-powered water heaters. In the case of gas heating, a carbon monoxide sensor is mandatory. However, it would also be reasonable to install a sensor in all living spaces that are connected to the combustion process, such as wood-burning ovens, fireplaces, stoves, etc.

The installation of a carbon monoxide detector is optional if the construction prevents the generation of carbon monoxide and its entry into the living space. This can be achieved by allowing combustion air to directly enter the heating device from the outside air, and directing the combustion gases directly to the outside air through the chimney. In such cases, the installation of a sensor is not mandatory.

How does a carbon monoxide sensor work?

A carbon monoxide sensor triggers an alarm when the level of carbon monoxide in the air reaches a dangerous point for human health or life. It is recommended to have a carbon monoxide detector in every room, as it only indicates the concentration of carbon monoxide present in the immediate vicinity of the device.

Why is carbon monoxide dangerous?

The inhalation of toxic gases, including carbon monoxide or carbon dioxide, is the main cause of death during fires. Carbon monoxide is a colorless, odorless, and tasteless gas that spreads in a way that often goes unnoticed by people. The initial symptoms of carbon monoxide poisoning include headaches, dizziness, fatigue, and nausea. While awake, a person may often fail to associate these symptoms with carbon monoxide, and they may not perceive them at all while asleep.

Where should the carbon monoxide sensor be installed?

During installation, it is essential to follow the manufacturer’s instructions. Unlike smoke detectors, which are mounted on the ceiling, carbon monoxide detectors should be attached to the wall of the room, approximately one and a half to two meters above the floor. Specialists recommend installing the sensor at breathing height, which corresponds to the level of a person’s face when sitting on the sofa in the living room and at the height of the pillow in the bedroom.

The sensor should be installed at a distance of 1-3 meters from the carbon monoxide source, and it should not be placed near ventilation systems or air ducts.

In multi-story buildings, a carbon monoxide sensor should be installed on each floor and, if possible, in each bedroom.

If the gas boiler is located in the bathroom, it is important to ensure that the carbon monoxide sensor is suitable for use in humid conditions. Look for the IP marking on the product, which should be at least IP44.

The carbon monoxide detector should not be installed in garages, kitchens, boiler rooms, or areas where the temperature exceeds 40 degrees Celsius or drops below 10 degrees Celsius.

How to maintain a carbon monoxide detector?

The operational status of the carbon monoxide sensor should be checked once a month by pressing the control button. A beeping sound confirms that the device is functioning properly.
The carbon monoxide detector must be regularly cleaned of dust and dirt. A vacuum cleaner or a cloth can be used for this purpose.

The carbon monoxide sensor is battery-powered, and it signals low battery levels with an intermittent sound signal. When this occurs, the battery should be replaced immediately.
