BSI对火灾探测和火灾报警系统标准进行修订

发布时间: 2017-12-27 15:18:13   审校:睿智  

 

英国标准协会(BSI)修订了火灾探测和火灾报警系统的标准。BS 5839-1:2017标准涵盖了商业建筑物及其周围的火灾探测和火灾报警系统的规划、设计、安装、调试和维护。 

BS 5839-1:2017关于建筑物火灾探测和火灾报警系统标准,用于非住宅房屋系统的设计、安装、调试和维护的规程是参照两卷中的政府消防安全指南,批准文件B中包括英格兰的建筑规定,也涵盖消防安全事宜和周围的建筑物。

国家安监总局是其中一个针对BS 5839-1提出建议的组织,因此它对承包商来说至关重要。修订后的标准与涉及所有与非住宅房屋火灾报警和检测系统的调试、安装、设计和规划相关的人员。

修订后的标准中一些关键变化如下: 

i.)         修改了L2火灾报警系统的定义。L2火灾报警系统旨在为建筑物内的所有逃生路线提供自动检测服务;

ii.)       修订后的指南收录了应用、测试多传感器探测器中不同传感器的方法;

iii.)      第17、18条要求阐明应用了语音报警装置(VAD)及视频图像设备(VID)

iv.)      标准中其中一部分是关于供电测试,以及电池或应急电源应持续时长;

v.)       针对夜间工作人员的指导,以便他们能够识别警报。

BSI建筑环境市场开发部负责人安特·伯德(Ant Burd)说:“BS 5839-1根据消防工业协会和消防总长协会的意见进行了修改。

“对于任何参与安装或维护商业火灾探测和火灾报警器的人员来说,这是一份准入文档,对于业内承包商来说是必不可少的。”

在标准的正文中,术语“火灾探测和报警系统”指的是系统中包含一个或两个手动呼叫点、鸣响器,以及联合了大量自动火灾探测器、手动呼叫点、鸣响器的复杂网络系统。

该术语还包括能够提供信号以启动其他消防系统和设备(例如灭火系统、烟雾控制系统、自动门释放设备)操作的系统或安全措施(例如关闭空气处理系统,关闭油阀或气阀、升降机)。它不适用于其他系统和设备,也适用于其辅助电路与接口。

BS 7273系列的有关部分介绍了BS 5839-1中所述的系统对某些消防系统运行设施进行规划、安装和维修的建议。同样地,BS 5839-1也未给出在任何给定的场所都要安装火灾报警系统的建议。关于住宅火灾探测和报警系统的建议见BS 5839-6。

这项标准预计会与这些主要组织相关:消防工业协会;电气承办商协会;国家电气安装检验委员会;消防安全协会;预防损失认证委员会;国家安全监察局;消防主任协会;安全系统和警报检查委员会;特许建筑服务工程师学会;英国电缆协会;BRE建筑研究院;电气工程师

学会;全国消防员协会;伦敦消防和应急规划局。

 

BSI revises standard for fire detection and fire alarm systems

BSI, the business standards company, has revised its standard for fire detection and fire alarm systems. The standard, BS 5839-1:2017, covers the planning, design, installation, commissioning and maintenance of fire detection and fire alarm systems in and around

commercial buildings. 

BS 5839-1:2017 Fire detection and fire alarm system for buildings. Code of practice for design, installation and commissioning and maintenance of systems in non-domestic premises is referred to in both volumes of the government’s statuary guidance for fire safety,

Approved Document B, which concerns building regulations [in England] covering fire safety matters within and around buildings.

The National Security Inspectorate is among organizations which consider the recommendations given in BS 5839-1 mandatory, and thus essential for contractors to follow. The revised standard is relevant to anyone involved in the commissioning, installation, design

and planning of fire alarm and detection systems for non-residential dwellings.

Some of the key changes over the standard it replaces include: 

i.)            Improved definition of the L2 fire alarm system. L2 Fire Alarm Systems are designed to offer automatic detection on all escape routes within a building

ii.)           Modified guidance for use of multi-sector detectors, with distinct sections dedicated to both the application and testing of these

iii.)          Clauses 17 and 18 require clarification as to the use of Voice Alarm Detectors (VADs) and Visual Indicator Devices (VID)

iv.)         Inclusion of a section in the standard concerning the testing of the power supply, and how long any batteries or contingency power supply should last for

v.)          Guidance for persons who work at night so they can recognize the alarm

Ant Burd, Head of Market Development for Built Environment at BSI, said: “BS 5839-1 was revised with input from the Fire Industry Association and the Chief Fire Officers Association.

“It will be a go-to document for anyone involved in the installation or maintenance of commercial fire detection and fire alarms, and will prove essential for contractors in the industry.”

The term ‘fire detection and alarm systems’, in the context of this standard, includes systems comprising of only one or two manual call points and sounders, as well as complex networked systems that incorporate a large number of automatic fire detectors, manual

call points and sounders.

The term also includes systems which are capable of providing signals to initiate the operation of the other fire protection systems and equipment (such as fire extinguishing systems, smoke control systems or automatic door release equipment) or safety measures

(such as the shutting down of air handling systems, closing of oil or gas valves, or grounding of lifts). It does not apply to other systems and equipment themselves, or the ancillary circuits to interface with them.

Recommendations for the planning, installation and servicing of facilities for operation of certain fire protection systems by the systems addressed within BS 5839-1 are given in the relevant part of the BS 7273 series. Equally, BS 5839-1 does not recommend whether

or not a fire alarm system should be installed in any given premises. Recommendations for fire detection and alarm systems in dwellings are covered in BS 5839-6.

Some notable organizations which the standard is expected to be relevant to include: Fire Industry Association; Electrical  Contractors Association; National Inspection Council for Electrical Installation; Fire Safety Association; Loss Prevention Certification Board;

National Security Inspectorate; Chief Fire Officers Association; Security Systems and Alarms Inspection Board; Chartered Institution of Building Services Engineers; British Cables Association; BRE Building Research Establishment; Institution of Electrical Engineers;

National Association of Fire Officers; London Fire and Emergency Planning Authority.
