Introduction
Line type heat detectors (LTHD) 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 LTHD products. LTHD are based upon many
unique operating principles. It is the intention of this standard to define common operating characteristics for
each type of LTHD in conjunction with existing EN 54 detector standards, so that line type heat detectors have
a response behaviour comparable to that of point type heat detectors.
Due to the various applications for LTHD, 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 LTHD 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 LTHD: non-integrating and integrating systems.
Therefore the subclasses A1N, A2N, BN, … GN have been created for non integrating systems and the
subclasses A1I, A2I, BI, … GI have been created for integrating systems.
1 Scope
This European Standard applies to LTHD consisting of a sensing element using an optical fibre, a pneumatic
tube or an electrical sensor cable connected to a sensor control unit, or 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 buildings and tunnels.
This standard also covers LTHD intended for use in the local protection of plants and machinery.
LTHD with special characteristics and developed for specific risks are not covered by this standard.
This standard specifies the requirements and performance criteria. This standard specifies the corresponding
test methods and the evaluation of conformity of the product to the standard.

3 Terms, definitions and abbreviations
For the purposes of this document the terms and definitions given in EN 54-1:1996 and the following apply.
3.1 Terms and definitions
3.1.1
analogue detector
detectors, the sensing element of which, produces an output signal functionally related to the heat sensed.
3.1.2

the function of the line type heat detector.
EXAMPLE Terminating device, filter, switch
3.1.3
integrating detector
detectors where the response to temperature is summed in some way, (not necessarily linearly), along a
length of the sensing element. For such detectors, the output to the sensor control unit is therefore a function
