Fire detection and fire alarm systems - Carbon monoxide detectors. Point detectors Ingestion-build-264231 wall bushing or a bushing1 Scope This European Standard specifies requirements, test methods and performance criteria for point detectors using carbon monoxide sensing for use in fire detection and fire alarm systems in and around buildings (see EN 541: 2011). This European Standard provides for the assessment and verification of consistency of performance (AVCP) of carbon monoxide point detectors to this EN. This European Standard does not apply to fire detectors
