| ANOTACE "ČSN EN 54-28 This European Standard applies to non-resettable line-type heat detectors consisting of a sensing element using an electrical sensor cable which can be connected to a sensor control unit or 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 (see EN 54 1:2011). The non-resettable sensing element has a fixed temperature alarm threshold and does not distinguish between short circuit and alarm condition. This European Standard specifies the requirements and performance criteria, the corresponding test methods and provides for the Assessment and Verification of Constancy of Performance (AVCP) of non-resettable line-type heat detectors to this European Standard. 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." | ||
