紧急出口装置是安装于公共场所出口门内侧的门控装置。紧急情况发生后,场所内人员涌向出口门,轻触或按压该装置的触发部位(actuating bar),即可瞬间开启门锁将门打开向外逃生。美国消防协会(NFPA)在《生命安全规范》(NFPA 101)中对紧急出口装置的定义是:“由一个门锁和一个向外出逃方向施力即能将此门锁开启的机构组成的装置”。国内目前仅有行业标准SN/T 1878-2007《紧急出口装置通用技术要求》,对该装置做了具体规定,该标准以等同采用ANSI/BHMA A156.3-2001的方式制定。本文分析了ANSI/BHMA A156.3《紧急出口装置》2008版与2001版的主要差异,并对2008版中备受关注的热熔防火销做了重点介绍。
Emergency exit device is installed in public places inside the exit gate control device. After an emergency, personnel in the facility flock to the exit door, and by touching or pressing the actuating bar of the device, the door can be unlocked momentarily to open the door to escape. The National Fire Protection Association (NFPA) defines emergency exit devices in the Code of Safety in Life (NFPA 101) as follows: “A mechanism consisting of a door lock and an outward force to open the door Device ”. Currently only the industry standard SN / T 1878-2007 “emergency exit device general technical requirements” to make the specific provisions of the device, the standard equivalent to adopt ANSI / BHMA A156.3-2001 approach. This article examines the major differences between the 2008 and 2001 versions of the ANSI / BHMA A156.3 Emergency Exit Device and highlights highlights of the 2008 release of hot melt fire pegs.
