Discussion about the Design of Automatic Fire Alarm System for High and Large Open Space

高大开放式空间建筑火灾自动报警系统的设计是现代建筑电气设计的新兴和难点领域。本文结合工程实例分析了高大空间建筑火灾探测存在的烟雾分层、烟雾稀释等问题,比较了极早期火灾探测器与传统火灾探测器的优缺点。论述了高大开放式空间建筑火灾自动报警系统选用极早期空气采样探测器的合理性。

The design of automatic fire alarm system for high and large open space buildings is the new and difficult areas for electrical design of modern building electricity design. In this paper, combined with engineering examples, issues such as smoke layering and smoke dilution in the fire detection for high and large space buildings are analyzed, and the advantages and disadvantages of extremely early fire detectors are compared with those of the traditional fire detectors. The rationality of selection of extremely early air sampling detector for automatic fire alarm system of the high and large open space building is discussed.
