本文件适用于可重置线型热探测器，该探测器由一个传感元件组成，该传感元件沿其长度连续或离散分布，并直接或通过接口模块连接到传感器控制单元，用于安装在建筑物内和周围以及其他土木工程中的火灾探测和火灾报警系统。此类技术的示例包括光纤、气动管或电气传感器电缆 本文件规定了要求和性能标准、相应的测试方法，并提供了评估。 本文件还涵盖了用于工厂和设备本地保护的可重置线型热探测器。 本文件不包括只能响应一次且基于固定温度电缆的不可重置线型热探测器。

This document 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 plants and equipment. This document does not cover non-resettable line-type heat detectors that can only respond once and are based on fixed temperature electrical cables.
