Fire Detection, Heat-Actuated

Heat sensitive devices may be either "spot" or "line" type and operate at a fixed temperature or on a rapid increase in

temperature (rate-of-rise). Some detectors combine the fixed and rate sensitive principles.

The spacing guides listed are indicative of each detector"s relative sensitivity and, in each case, the spacing guide is the

maximum recommended separation between detectors for smooth-ceiling installations. For a given temperature rating, a

fixed-temperature detector which has a 30 ft (9 m) listing and one which has a 15 ft (5 m) listing will both respond at

approximately the same time to a geometrically growing fire if each is installed at its listed spacing. FM Approved rate-of-rise

detectors all have 30 ft (9 m) listed spacings, the maximum separation recommended by FM Approvals.

Installation of heat detectors at less than maximum spacing is necessary: to achieve earlier response; to compensate for ceiling

obstructions such as beams and joists; and to compensate for ceiling heights greater than 15 ft (5 m). Proper location and use of

heat detectors involves consideration of ceiling construction, the location of partitions, the maximum normal room temperature,

heat produced by the occupancy, and whether detector function is to warn occupants or to automatically actuate protection

equipment. Refer to Standard 72-1993 of the

昨日上午10时许，在临淮路与天长路交口一汽配店二楼仓库，发生失火，由于火势蔓延，引发大量冷煤罐发生爆炸，损失惨重编辑，所幸未造成人员受伤。 编辑赶到时，火势已被扑灭，消防员正在调查失火原因。二楼仓库的窗户只剩下框架，边缘处都是炙烤后的焦痕，地上散落了大量碎玻璃，汽配店工作人员正在搬运其他货物。据获悉，店里的工作人员发现二楼蹿出浓烟报道，上楼查看中，突然传出剧烈的爆炸声响，循声望去，优质CTI-155X缆式线型感温火灾探测器服务商,正宗火警探测、报警设备，进来的十几箱冷煤罐已着火，持续发出炸响声，甚至飞溅砸破玻璃，优质CTI-155X缆式线型感温火灾探测器服务商,优质火警探测、报警设备，崩到窗外。在离门面约十多米远地方，上海道夫自动化仪表工程有限公司,道夫自动化仪表工程,散落了十几个瓶瓶罐罐，都已挤压变形。据报道以为，火灾给老板造成四五万元损失。 根据通知要求，此次专项治理主要分自查自改、督查整改、全面总结等三个阶段组织实施。目前，相关餐饮场所正对照有关规定、标准和要求，按序时进度认真进行自查自改，对查出的隐患，逐一登记、建档，落实整改，切实做到整改措施、责任、资金、时限和预案“五落实”，并将执行燃气防爆有关规定的情况、存在问题及整改计划报相关主管部门。下一步，优质CTI-155X缆式线型感温火灾探测器服务商,正宗火警探测、报警设备供应厂家，各有关部门将组织专家深入现场，进行指导和服务，大力宣传燃气防爆安全知识和有关安全管理要求，及时排查和消除安全隐患，确保安全稳定。 美国7家保险公司近日向丰田汽车提起诉讼，试图追偿在丰田汽车事故中赔付的保险金。保险公司起诉称，在丰田汽车突然加速导致的725起汽车事故中，事故原因是由于丰田汽车没有安装刹车优先系统。丰田发言人Celeste Migliore表示：“任何关于丰田汽车因自身存在缺陷导致汽车突然加速的指控都是毫无根据的。”对丰田提出追偿诉讼的保险公司有美国汽车保险公司、消防员基金保险公司、美国国家担保公司、Ameriprise保险、财产意外保险公司、车主相互保险公司和美国五金相互保险公司。不久前，丰田在一起诉讼中向雷克萨斯车祸的受害人家属支付了1000万美元，以达成庭外和解。
