Fire detection and fire alarm system - Part 22: Line type heat detectors

This European Standard applies to 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 buildings and tunnels.
This standard also covers line type heat detectors intended for use in the local protection of plant and machinery.
Line type heat detectors with special characteristics and developed for specific risks are not covered by this standard.
This standard also does not cover line type heat detectors that are based on non-resettable, fixed temperature electrical cables (so called "digital" systems).
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.

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
