Fire detection and fire alarm systems - Multi-sensor fire detectors. Point detectors using a combination of carbon monoxide and heat sensors1 Scope This European Standard specifies requirements, test methods and performance criteria for point type multi sensor fire detectors for use in fire detection systems installed in and around buildings (see EN 541: 2011), incorporating in one mechanical enclosure at least one carbon monoxide sensor and at least one heat sensor and where the overall fire detection performance is determined utilizing the combination of the detected phenomena.
