关于易燃珍善品储存场所消防报警设计的思考

Consideration on the Design of Fire Alarm for Storage Site of Inf lammable Rarity and Treasure

储存易燃珍善品场所消防报警设计的通常做法:选用感烟探测器和感温探测器的组合,气体灭火系统在接到两个独立的火灾信号后才启动。存在的问题:火灾现场温度上升到感温探测器的动作温度时,部分珍贵保护对象可能已经被损毁。考虑藏品的唯一性和不可复制性,其储存场所消防设计应从以下两方面入手:①灭火介质的选择(以气体灭火系统为宜);②火灾自动报警系统的选择(可考虑烟—烟的两个独立信号的组合,而提早灭火控制系统的启动时间)。

The common approach of fire alarm design for the storage site of inflammable rarity and treasure is： adopting the combination of smoke detector and temperature detector, the gas extinguishing system will start after it receives the two independent fire alarm signals. The existing problem is： when the temperature on the fire site rises to the operating temperature of the temperature detector, part of precious objects to be protected may have been burnt out. Considering the uniqueness and nonreproducibility of the museum pieces, the fire alarm design for the storage site of them should proceed with from the following two aspects： selection of the fire extinguishing medium （gas extinguishing system is proper）; selection of the automatic fire warning system （the combination of two independent signals-smoke to smoke can be considered to advance the starting time of the fire extinguishing control system） .
