ULC标准很高兴地宣布，第二版CAN/ULC-S559-13《火灾信号接收中心和系统设备标准》于2013年1月发布。加拿大国家标准由ULC火灾报警和生命安全设备及系统委员会处理和批准。本标准中的要求与CAN/ULC-S561-13《火灾信号接收中心和系统的安装和服务》一致，并广泛借鉴了CAN/ULCS-527-11《火灾报警系统控制单元》中的要求。CAN/ULC-S559涵盖了火灾信号接收中心和系统的要求，包括发射和接收设备、专有火灾接收中心设备和控制单元附件。 火灾信号接收中心系统包括受保护的房屋单元和普通（非危险）室内外位置的接收器。消防信号接收中心和系统设备拟使用的编程方法、测试、服务和其他软件包括在设备评估中。 消防信号接收中心、卫星中心、信号处理中心和桥接中心中使用的信号接收装置也包含在本标准的要求中。本版标准进行了更新，以应对技术进步，其中包括但不限于以下修订:对结构、标记和性能要求进行了修改，以适应信号接收中心的应用； 针对火灾信号接收中心应用的更具描述性的产品标记；整合信号接收中心和专有系统，以确保一致性；检测危及通信电路的替代技术的测试要求；承认在通信系统中使用自动化软件、互联网和VOIP的可靠性；以及对信号安全的新要求。

ULC Standards is pleased to announce the publication of the Second Edition CAN/ULC-S559-13, Standard for Equipment for Fire Signal Receiving Centres and Systems, published under the date of January 2013. This National Standard of Canada was processed and approved by the ULC Committee on Fire Alarm and Life Safety Equipment and Systems.The requirements in this Standard were aligned with CAN/ULC-S561-13, Installation and Services for Fire Signal Receiving Centres and Systems, and have drawn extensively from the requirements contained in CAN/ULCS-527-11, Control Units for Fire Alarm Systems.CAN/ULC-S559 covers requirements for fire signal receiving centres and systems, which include transmitting and receiving equipment, proprietary fire receiving centre equipment and control unit accessories. Fire signal receiving centre systems include protected premise unit and receiver for ordinary (non-hazardous) indoor and outdoor locations. Programming methods, test, service and other software intended for use with the equipment for fire signal receiving centres and systems are included in the evaluation of the equipment. Signal receiving units used in fire signal receiving centres, satellite centres, signal processing centres and bridging centres are also covered by the requirements in this Standard.This edition of the standard was updated to address technological advancements, which include, but not limited to the following revisions:Construction, marking and performance requirements were modified to customize with signal receiving centre applications;More descriptive product markings that are specific to fire signal receiving centre application;Integration of signal receiving centres and proprietary systems to ensure consistency;Testing requirements to detect substitution technology which compromises communication circuits;Recognition of the use of automation software, internet and VOIP reliability in communication systems; andNew requirements for security of signals.
