DIGITAL LINEAR HEAT DETECTION PERFORMANCE CHARACTERISTICS KIDDE ALARMLINE Linear Heat Detection System POINT OF RISK MONITORING BENEFITS I Detection at point of Alarmline Linear Heat Detection (LHD) cable-based systems provide economical temperature monitoring at the precise point of risk. The system is reliable, flexible and has the ability to detect abnormal temperature variances before fire breaks out. Kidde Fire Protection"s comprehensive LHD product portfolio allows a vast range of commercial and industrial fire and overheat risks to be protected, in ambient temperatures of -65 to +238°C risk I Continuois operation within the most adverse environmental Combined cable and detector APPLICATIONS 1 Electrical and mechanical flexibility Cable tunnels Cable tray installations at power stations, airport terminals and railway station complexes can

I Internationally proven be protected by the local installation of Alarmline sensor cables above and below traywork. Fire detection performance is unaffected by adverse environments and response times are potentially less than 10 seconds. I Integration with central fire control systems Floating roof tanks The petrochemical industry requires that fires in these tanks caused by the ignition of combustible gases are extinguished in a short time frame. A rim seal Alarmline instalation will provide enhanced detection of fire allowing an appropriate rapid extinguishing response Conveyors Overheated bearings on conveyor beit support rollers can be rapidly detected. Additional Alarmline protection can be provided above and below the belt, against spillage and the transportation of ignited material Bulk storage Alarmline In-rack protection at multiple levels ensures rapid fire detection. As part of a pre- action system, an advance warning of imminent sprinkler opera water damage to stored goods tion may avoid unnecessary Rail locomotives/rolling stock The flexibility of linear heat detect 　　3月25日夜里11点多，江苏兴化周庄镇一造纸厂突发大火，火势勐烈。接到报警后，上海道夫自动化仪表工程有限公司,道夫自动化仪表工程,兴化消防立即出动4辆车，周庄消防也出动1辆车赶赴火灾现场。大火一直持续了近7个小时才被扑灭。　　经过勘查了解到：起火部位为货品仓库，起火面积为200平方，整个仓库已经被火势重重包围。现场火光冲天，周边还堆放着许多成品纸，若不及时扑灭，后果不堪设想。根据现场情况，消防人员立即部署，对整个生产车间大火进行压制，一直到26日天早晨6点多，大火终于被扑灭。　　随后，消防官兵又对现场余火进行了清理，确认无复燃危险。　　据了解，进口H9650,服务商火警探测、报警设备，此次火灾并无人员伤亡，起火原因还在进一步调查中。 　　二是消防预警设备。这类设备主要是家庭内部防火防爆。根据针对性的强弱也可分为两个部分：一是针对性较强的设备，主要包括烟雾火警探测器和可燃气泄漏探测器，它们在烟雾或可燃气到一定的浓度时就会发出报警，而不是事发后才让用户知晓；二是针对性较弱的设备，主要智能开关、智能插座，进口H9650,优质火警探测、报警设备，这类设备可以对一些老化的家电电线使用情况进行及时反馈，进口H9650,原装火警探测、报警设备出售，甚至可以在发生情况时自动切断电源，做到保护电器和以免火灾发生。 DIGITAL LINEAR HEAT DETECTION TECHNICAL SPECIFICATION Tinned copper-covered steel Conductor diameter 0.3mm 100 ohms All cables Maximum conductor resistance per km at 20-c Veltope Rating Insuiation Material Temperature sensitive to 1 55mm thickness 8028, H8040, H8040N, H8045, H8045N each two cores fred, black) twinned together:3.0mm dia H8069: two cores (black, black and white) winned together: 3.0mm da H9650 two cores (white, black) twinned together: 3 Cmm da H8028: PVC (black;: 4 25mm dia H3069: PVC redi: 4 25mm dia 鳪 040 : Polythene brad ( red with green IO Inner Cores Outer Sheath tracer): 3.85mm dia H8040N: Iblack nylonij 3.0mrs dia H8045 Palythene braid [red with black ID tacerl 3.65mm dia H8045N: (black myloni 3.0rern dia H650 Ruorooolymer white 3.5mm dia Ordering Data For details of sensor supports consult Kidde Fire Protoction data sheet E9832-409 Alarmline Linear Approvals 1.
