| Resumen: | 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,
intended for use in fire detection and fire alarm systems installed
in and around buildings and other civil engineering works (see EN
54-1:2011). This European Standard specifies the requirements and
performance criteria, the corresponding test methods and provides
for the Assessment and Verification of Constancy of Performance
(AVCP) of resettable line-type heat detectors to this EN. 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 EN. This
European Standard does not cover line-type heat detectors that are
based on non-resettable, fixed temperature electrical cables (so
called digital systems).
