This guide provides guidelines for the organization' of fossil-fueled power generating plant alarm and monitoring information into types and categories@ taking into consideration information usefulness and limitations. This guide further serves to establish guidelines for correlating type and category of alarm and monitoring information with the appropriate information-display devices. Adherence to the categorization and the corresponding information-display techniques presents prioritized alarm and monitoring information to the operator which is appropriately proportioned between the window annunciator@ CRT@ mimic display@ and printer. This also permits a reduction in the number of window annunciators over historic practices. Purpose. It is the purpose of this guide to define the logical classifications for categories of plant information and to identify display techniques available for monitoring and reporting this information to plant personnel. Use of this guide will: (1) Aid engineers in achieving a balanced and integrated design in alarm monitoring systems (2) Assist control-room operator@ supervisory@ and training personnel (3) Improve proficiency of control room operators (4) Enhance plant generating station safety@ efficiency@ and availability
