28、y and the United Kingdom. BS EN 54-28:2016EN 54-28:2016 (E) 6 Introduction Non-resettable line-type heat detectors (NLTHD) have been used for a considerable number of years and are incorporated into fire detection systems and in some countries even into fire alarm systems if accepted by the relevant
29、 authorities. These detectors are typically used in areas where point type heat detectors are presented with challenging environmental characteristics and also, where access to the detectors, may significantly influence the fire alarm system design. This standard defines the minimum system functiona
30、lity for NLTHD products. Due to the various applications for NLTHD, it is necessary to devise separate environmental classification tests for the sensing element and the sensor control units of these systems. It is not the purpose of this standard to define applications or how NLTHD should be used i
31、n applications. Generally NLTHD operate on using the same basic principle. However, they can have different performance with respect to the temperature response. Therefore they have been differentiated by a type code which reflects the nominal alarm temperature, the tolerance range and the maximum a
32、mbient temperature at which they could be used. BS EN 54-28:2016EN 54-28:2016 (E) 7 1 Scope 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
33、 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 disti
34、nguish 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
35、 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. 2 Normative r
