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.
