Over deze norm
This European Standard applies to non-resettable (digital) line type heat detectors consisting of a sensing element using 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 and around buildings and civil engineering works. The non-resettable sensing element has a fixed temperature alarm threshold and does not distinguish between short circuit and alarm condition. This European Standard also covers non-resettable line type heat detectors intended for use in the local protection of plant and equipment. Non-resettable line type heat detectors with special characteristics and developed for specific risks are not covered by this standard. This European Standard specifies the requirements and performance criteria, the corresponding test methods and the evaluation of conformity of the product to the standard.
