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.

Where such connections are present the detector shall be assessed
