BS EN 54-222015 EN 54-222015 E 6 Introduction Resettable line-type heat detectors RLTHD have been incorporated into fire alarm systems for a considerable number of years. 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 functionality for RLTHD products. RLTHD are based upon many unique operating principles. It is the intention of this standard to define common operating characteristics for each type of RLTHD in conjunction with existing EN 54 detector standards, so that resettable line-type heat detectors have a response behaviour comparable to that of point type heat detectors. Due to the various applications for RLTHD, 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 RLTHD should be used in applications. However, the standard indicates two general fields of application, room protection and secondly local protection. The standard defines separate response test classifications for these two fields. Generally there are two functional principles employed by RLTHD non-integrating and integrating systems. Therefore separated subclasses have been created for non integrating systems and for integrating systems. BS EN 54-222015 EN 54-222015 E 7 1 Scope This European Standard applies to resettable 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, intended for use in fire detection and fire alarm systems installed in and around buildings and other civil engineering works see EN 54-12011. 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 resettable line-type heat detectors to this EN. This European Standard also covers resettable line-type heat detectors intended for use in the local protection of plant and equipment. Resettable line-type heat detectors with special characteristics and developed for specific risks are not covered by this EN. This European Standard does not cover line-type heat detectors that are based on non-resettable, fixed temperature electrical cables so called “digital” systems. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

For such detectors, the output to the sensor control unit is therefore a function of the temperature distribution along the length of the sensing element EXAMPLE Pneumatic systems. 3.1.3 linear line-type heat detector detectors which respond to heat applied to any point along the length of the sensing element 3.1.4 line-type heat detector LTHD detector which responds to heat sensed in the vicinity of a continuous line Note 1 to entry: A line-type heat detector may consist of a sensor control unit, a sensing element and functional units. 3.1.5 local protection application applica
