专业H8045N LHD制造商_优质火警探测、报警设备服务商-上海道夫自动化仪表工程有限公司

General

The siemple and proven technology of digital Linear Heat

Detection (LHD) cable, makes it a product of choice for

difficult and challenging applications where other

technologies struggle to work.

With it’s ease of installation and low maintenance it also

provides a cost effective solution where project

expenditure requires to be kept at a minimum.

The sensing cable is formed from a pair of twisted steel

conductors each with temperature sensitive insulation

and then an overall Nylon outer sleeve. When the

temperature sensitive insulation reaches it’s

predetermined alarm temperature the two conductors

short together providing the digital or switched signal.

The cable can be connected to any unit capable of

monitoring a switched signal, i.e. Conventional fire

panel, addressable switch monitor unit or PLC.

The nylon outer sleeve of the H8040N offers good

chemical and water resistance, allowing it to be

deployed in harsh and dirty environments.

　　依据《电气用品安全法施行令》第九条，上海道夫自动化仪表工程有限公司,道夫自动化仪表工程,以下相关LED灯、LED灯具已成为管制对象：额定电压100V～300V，50Hz、60Hz，正宗H8040 LHD感温报警器,优质火警探测、报警设备，额定功率1W及以上、有一个金属灯头的LED灯泡;额定电压100V～300V，50Hz、60Hz，额定功率1W及以上的LED灯具(防爆灯具除外)。纳入管制的LED灯、LED灯具，圆形PSE测试所依据的安全和电磁兼容标准只有省令1项，省令2项的协调标准尚未出台，正宗H8040 LHD感温报警器,原装进口火警探测、报警设备，因此与LED相关的IEC标准不在《电气用品安全法》接受范围。日本通过分门别类进行抽查管制电气用品。目前，日本主要用E14、E26灯头，国内企业出口这类产品时需要注意灯头的规格。中国的大功率LED产品可以出口到日本，灯管出口到日本无需PSE认证，灯具、电源以及直流灯杯可以通过独立包装出口合理规避日本法规。 　　那么这些鱼龙混杂的销售门店，正宗H8040 LHD感温报警器,正宗火警探测、报警设备制造厂家，是否具有防火卷帘门的销售资质呢?10月6日，记者向公安部消防局科技处进行了咨询，据一名陈姓工作人员介绍，防火卷帘门生产企业必须获取公安部消防产品合格评定中心下发的消防产品型式认可证书，方可生产、销售、安装防火卷帘门产品。消费者若想了解一家企业是否具有合格消防产品的生产资质，可以通过中国消防产品信息网进行查询，在该网站提供的“中国消防产品质量信息查询系统”中输入关键词，就能查询到生产消防产品的企业信息以及获得市场准入时候的检验报告的详细内容。
