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 National Fire Protection Association and design specifications published by

jurisdictional authorities, as appropriate.

宝马日前宣布将从2003年8月1日起，开始受理新款5系列的预约定单。最早于今年10月底交车。将要投放日本市场的新车共三款，分别为“525i”、“530i”及“545i”，均配有汽油引擎。价格方面，525i为570万日元（约合人民币35.6万元）；530i为675万日元（约合人民币42.2万元）；545i为880万日元（约合人民币55万元）。 　　新款5系列中，配备17英寸和18英寸车轮的530i和545i标准配备防爆轮胎，正规CTI-TC105感温火灾探测电缆105供应商,铜芯电缆相关，即使爆胎也可行驶一段距离。在17英寸车轮上，采用普利斯通（Bridgestone）生产的侧面加强型防爆轮胎。车体尺寸为长4841×宽1846×高1468mm，轴距2888mm。与现行款相比，长、宽、高分别增加了66mm、46mm及33mm，轮距增加了58mm。 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，上海道夫自动化仪表工程有限公司,道夫自动化仪表工程,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CelesteMigliore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。 　　半个多世纪以来，正规CTI-TC105感温火灾探测电缆105供应商,铝芯电缆相关，赛多利斯工业技术一直在不断创新和改进称量技术，始终走在称量技术发展的最前沿。目前，赛多利斯工业称重产品遍布各个领域，既有在欧莱雅洗发香波生产线上，正规CTI-TC105感温火灾探测电缆105供应商,信号电缆相关，相对精度达到20万分之一的配料系统，也有单只量程高达500吨的柱式传感器——被BASF公司用在世界各地的巨型料仓上;既有用于诺华制药疫苗生产线上最高洁净环境、满足卫生设计要求的IF不锈钢超薄台秤;也有随Jules Verne号运载火箭进入国际空间站的防爆工业秤和传感器。
