Description

This part of ISO 7240 applies to resettable line-type heat detectors consisting of a sensing element distributed either continuously or discretely at close intervals along its length and 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. Examples of such technology are an optical fibre, a pneumatic tube, or an electrical sensor cable

This document specifies the requirements and performance criteria, the corresponding test methods and provides for the Assessment.

This document also covers resettable line-type heat detectors intended for use in the local protection of plant and equipment.

This document does not cover line-type heat detectors that are based on non-resettable, fixed temperature electrical cables (so called “digital” systems).
