1.1 本指南涵盖除喷水灭火系统以外的船上火灾探测系统的选择、安装、维护和测试。 1.2 本指南适用于所有规划、设计、安装或使用船上火灾报警系统的人员。由于本指南包括监管要求，因此适用于受监管和船舶分类规则约束的船舶。然而，本文所述的原则也适用于不需要满足火灾探测和报警系统法规的不受监管的商业船只、游乐船只、军用船只和类似船只。 1.3 限制-- 本指南不构成法规或船舶分类规则，适用时必须查阅这些法规或规则。 1.4 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 船上火灾探测系统的目的是提供警报，以减少火灾对生命安全的威胁，并将火灾对船舶运行的威胁降至最低。 鉴于很少有船只在尺寸或布局上相同，因此火灾探测系统必须进行相应的定制设计。一个精心设计的系统提供了一个合理的替代品，可以让机组人员在每个可能发生火灾的受保护空间持续监视火灾。 4.2 火灾探测系统的基本功能是在实际情况下尽快自动可靠地指示火灾情况，并提醒责任人火灾的存在和位置。本系统设计和应用指南介绍了系统布局中的各个步骤，并概述了设计系统所需的信息。 4.3 美国海岸警卫队和国际海上人命安全公约（SOLAS）法规已被列为本指南中的要求。为确保完整有效的系统或纳入良好行业实践而制定的其他指南作为建议。

1.1 This guide covers the selection, installation, maintenance, and testing of shipboard fire detection systems other than sprinkler systems. 1.2 This guide is intended for use by all persons planning, designing, installing, or using fire alarm systems onboard vessels. As it includes regulatory requirements, this guide addresses those vessels subject to regulations and ship classification rules. However, the principles stated herein are also suitable for unregulated commercial vessels, pleasure craft, military vessels, and similar vessels that are not required to meet regulations for fire detection and alarm systems. 1.3 Limitations— This guide does not constitute regulations or ship classification rules, which must be consulted when applicable. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 The purpose of a shipboard fire detection system is to provide warning so as to reduce the life safety threat from fire and to minimize the fire threat to the operation of the ship. Given that few ships are identical either in size or layout, it follows that the fire detection system will have to be custom designed accordingly. A well-designed system provides a reasonable substitute to having crew members on constant fire watch in every protected space where a fire might occur. 4.2 The basic function of the fire detection system is to automatically and reliably indicate a fire condition as quickly as is practical and to alert responsible individuals of a fire's existence and location. This system design and application guide addresses the individual steps in the layout of the system and provides an overview of the information needed to design a system. 4.3 The U.S. Coast Guard and the International Convention for the Safety of Life at Sea (SOLAS) regulations have been stated as requirements within this guide. Additional guidelines to assure complete and effective systems or to incorporate good industry practices are stated as recommendations.
