本推荐规程旨在为设计工程师和最终的电厂操作员提供帮助。使用本推荐规程将为操作人员提供更连贯、更有用的电厂警报应用。本推荐规程的目标是减少报警差异、混乱、过度噪音水平和信息过载，但不适用于事件的事后分析。本推荐做法将解决以下报警相关问题。功能分组优先级顺序和一致性颜色格式和显示音频和音高确认、重置和测试功能干扰报警这些项目分别处理，并考虑它们之间的关系。 本推荐规程适用于使用灯或灯箱显示的报警，但不适用于基于软件的报警（例如，基于CRP的报警），旨在补充ISA-18.1-1979（R2004）、报警器序列和规范提供的信息。

This recommended practice is provided for the benefit of design engineers and, ultimately, plant operators. Use of this recommended practice will result in a more coherent and useful application of plant alarms for operations personnel. The goal of this recommended practice is to reduce alarm discrepancies, clutter, excessive noise levels, and information overload, but it is not intended for post-factum analysis of events.This recommended practice will address the following alarm-related issues.Functional groupingPrioritizationOrder and consistencyColorsFormats and displaysAudio tone and pitchAcknowledge, reset, and test functionsNuisance alarmsThese items are addressed both individually and with respect to their relationships with one another.This recommended practice pertains to alarms displayed using lights or light boxes, but not software-based alarms (e.g., CRP-based alarms) and is intended to supplement the information provided by ISA-18.1-1979 (R2004),Annunciator Sequences and Specifications.
