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 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. This European Standard specifies the requirements and performance criteria, the corresponding test methods and the evaluation of conformity of the product to the standard. 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 standard. This European Standard does not cover line-type heat detectors that are based on non-resettable, fixed temperature electrical cables (so called "digital" systems).

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.
