DIN EN 50292:2024-07

This document is intended primarily for persons who, in the course of their work, are responsible for installing carbon monoxide (CO) detection devices in residential buildings and rooms used for similar purposes. The document serves as a guide for the selection, installation, use, and maintenance of carbon monoxide detection devices intended for continuous operation in residential buildings, caravans, and boats when installed in a fixed location. This guide is intended to cover all types of private living spaces, including habitable recreational vehicles such as mobile and fixed caravans, as well as mobile homes and recreational boats such as canal boats. In cases where stationary caravans are used as permanent dwellings, EN 50291-1 shall apply. For all other types of caravans, EN 50291-2 shall apply. This guide should be read in conjunction with EN 50291-1 and EN 50291-2 and together with any additional applicable national or local regulations. This document refers to the installation of two types of devices: a) Type A devices for visual and audible alarms and with a switching function in the form of an output signal for direct or indirect control of ventilation or an additional device; b) Type B devices for visual and audible alarms only. This document is intended as a guide for persons who, in the course of their work, are required to install devices for the detection of carbon monoxide (CO) in residential buildings. It is also intended for anyone who may supply such detectors to the public for subsequent installation in accordance with national regulations, so that they can give recommendations based on good technical practice. Devices for the detection of carbon monoxide are not a substitute for the proper installation and regular maintenance of fuel-burning appliances or the regular cleaning of chimneys, even if they can offer the user additional safety. Carbon monoxide detectors for private use, with or without a switching function, can allay concerns about fuel safety and may be particularly useful in certain cases. It is important to understand that the toxicity of carbon monoxide can have different effects depending on a person's physical condition. Therefore, a carbon monoxide detector that complies with the EN 50291 series of standards may not fully protect people with certain medical conditions. This document excludes apparatus for the detection of combustible gases (see EN 50244) and for industrial installations or commercial premises. Carbon monoxide detectors are not intended as an alternative to smoke detectors.
