Projekta Nr.prEN 54-22
NosaukumsThis European Standard applies to line type heat detectors consisting of a sensing element using an optical fibre, a pneumatic tube or an electrical sensor cable connected to a sensor control unit, either directly or through an interface module to a control and indicating equipment intended for use in fire detection and fire alarm systems installed in buildings and tunnels. This standard also covers line type heat detectors intended for use in the local protection of plant and machinery. Line type heat detectors with special characteristics and developed for specific risks are not covered by this standard. This standard also does not cover line type heat detectors that are based on non-resettable, fixed temperature electrical cables (so called "digital" systems). This standard specifies the requirements and performance criteria. This standard specifies the corresponding test methods and the evaluation of conformity of the product to the standard.
