DIN Standards Committee Firefighting and Fire Protection

Overview

Duct smoke detectors (DSD) are used as part of a fire detection and fire alarm system or as a stand-alone actuator for a fire protection system to sample the air within air ducts of a building. Detection of smoke can be used as a signal to the connected control and indicating equipment and can be used as a signal to an air-handling system to prevent the spread of smoke within the building. A DSD is required to function satisfactorily not only in the event of a fire, but also in the conditions likely to be met in practice such as corrosion, vibration, direct impact, indirect shock and electromagnetic interference. Some tests specified are intended to assess the performance of the DSD under such conditions. The performance of DSD is assessed from results obtained in specific tests. This document is not intended to place any other restrictions on the design and construction of such equipment. An example for a stand-alone system is given in Annex K. The configuration of a fire detection and fire alarm system is given in EN 54-1. Annex L gives information on power supply. These requirements are system requirements or requirements on other components respectively and do not concern the product requirements of the DSD. This European Standard has been prepared by Technical Committee CEN/TC 72 "Fire detection and fire alarm systems" (secretariat: BSI, Great Britain); on the national level the responsible Working Committee is NA 031-02-01 AA "Brandmelde- und Feueralarmanlagen" ("Fire detection and fire alarm systems") of FNFW.
