slowly so that it takes longer than 5seconds to cover.The System Controller will signal Fire to the Fire Control Panel after the delay to fire has expired (10s default)Fault Test:Cover the Reflector completely within 2seconds.The System Controller will signal Fault back to the Fire Control Panel after the delay to fault has expired (10s default)Detector Fire LED Test Detector will signal Fire,System Controller will stay Normal.Press to exitwithout performing the testRelay/Controller Wiring Test System Controller signals ‘Fire’to Fire Control Panel Press or to exitIt is possible to perform a Fire Test from the System Controller,to test the wiring to the Fire Control PanelNOTE:The Remote Fire Test is acceptable for Fire Authority Acceptance and Routine Maintenance per

the Reflector are cleaned periodically with a soft lint-free cloth.If the Compensation Level for a particular Detector remains above130for several days,this indicates that cleaning should take place on that Detector.The system should be isolated from the Fire Control Panel before cleaning takes place.After cleaning,verify that the system is operating normally:If the Signal Strength is between92%and108%-leave the system to compensate back to100%(this should take no more than12hours)If the Signal Strength is above108%-reduce Compensation Level until Signal Strength is92—108%,and wait for system to compensate back to100%If the Signal Strength is below92%-perform LASER Targeting,Auto-Align,and Set.How to change Compensation Level:20.Troubleshooting21.1.Multiple Zone WiringWhen using more than one System Controller on a single zone of a conventional Fire Control Panel (FCP),it is important to choose the correct method of wiring.Incorrect wiring may result in a Controller isolating subsequent devices on that zone if it enters a Fault condition,and may prevent these subsequent devices signalling a Fire condition back to the FCP .If the FCP monitors for point detector removal,it is possible to use the following wiring diagrams which use diodes to provide zone continuity in the event of a Fault state on any Controller.Two Detectors connected to Controller:Single Detector connected to Controller on “Det 1”:Note 1–This component is the Fire Resistor.Its value is specified by the FCP manufacturer,and is not supplied with the System Controller.For U.S.installations it is typically a short circuit.Note 2–Recommended diode type:Schottky,60Volt,1Amp;must be UL listed for installations meeting NFPA72.Con C Fire Con D FaultFire Con A Fault Con BCon C Fire Con D FaultFire Con A Fault Con B1.Multiple Zone Wiring(continued)If the FCP does not monitor for detector removal,it is recommended that the following wiring diagram be used.For installations conforming to UL268and NFPA72,the following diagram MUST be used when wiring multiple Controllers onto one zone.Note1–This component is the Fire Resistor.Its value is specified by the FCP manufacturer, and is not supplied with the System Controller.For U.S.installations it is typically a short circuit.EOL–End of Line component.This is supplied with the FCP,and not supplied with the System Controller.Do NOT wire to any unused relay pairs.Con A and Con B are the relay outputs for Detector1;Con C and Con D are the relay outputs for Detector2.2.Event LoggerThe System Controller contains a logging function which will store information for the most recent 50events on each Detector.For each Fire or Fault activation,the controller will store:If there have been power-cycle events on the controller,all timing information will be lost for those events that occurred prior to the most recent of the power-cycles.To erase and restart the event logger,press and hold ‘left’and ‘right’keys together when displaying any of the event log entries.Press ‘tick’when prompted by ‘SurE’.To access the event log,press tick on the Event Logger icon when the relevant detector is highlighted:Event Number01is the most recent event 02is the event before 0103is the event before 02,and so on•The event code –This is the same as the error code (E-__)that would be displayed during the Fault,or one of the following:•99-Log erased •98-Power cycle •97-Fire Detected•96-Remote Fire Test initiated •95-AUTO initiated •94-LASER activated •93-‘Home’initiated•The elapsed time since the event occurred •The duration of the

线型感温探测器设计安装要求

线型感温探测器设计安装要求

线型感温探测器设计安装要求线型感温探测器具有超出其它类型探测器的独特优点,是应用于高风险易燃区和多种类型的工业、商业环境中的理想选择,特别是在具有安装困难和恶劣的条件下使用时,更能体现出传统的点式火灾探测器所不具备的优越性能。

线型感温探测器应根据设置场所的情况选择适宜的类型和安装方式,它是火灾自动报警系统有效和可靠运行的基础,因此线型感温探测器在使用时,必须有专业的设计、安装和完善的管理。

本文以下内容谨做参考。

1.1在设计前应做以下准备工作(1)环境温度的变化范围线型感温探测器具有多种温度等级,以适应正常的或周围环境产生的温度差。

选择合适的温度等级的探测器可以有效的、准确的探测火灾。

(2)线型感温探测器的探测分区和使用长度设定探测器防火分区的目的是为了迅速而准确的探测出被保护区域内发生火灾的部位,如果线型感温探测器的敷设跨越了探测分区,就无法准确的区分报警位置,甚至当一个分区的线型感温探测器出现了故障,会导致其它区域的火灾报警系统无法工作,降低了火灾报警系统的可靠性。

尤其是对于设有自动灭火系统的情况,更加要求准确报出发生火灾的部位,以便启动灭火系统进行火灾扑灭。

这就要求线型感温火灾探测器的一个回路不应跨越2个及以上的探测分区。

探测分区的长度可根据探测区域的重要程度、复杂程度、敷设电缆的特性确定,一般在70m~100m之间设定。

线型感温探测器的每个探测回路长度不宜大于120m。

1.2关于探测器的安装间距和保护范围线型感温探测器敷设区域火灾发生的过程,一般是温度升高→蓄热(受热)→产生可燃气体→产生烟雾→产生明火的过程,火灾早期探测的关键在于温度升高的阶段。

一般线型感温探测器在2m范围内可以对火灾的温度变化快速反应,即线型感温探测器的保护宽度为电缆周围±2m,如超出此范围,线型感温探测器对火灾温度的反应相对变慢,因此设计时应考虑线型感温探测器的保护范围。

另外,如果感温电缆的安装间距过大,也不能快速有效的探测中间区域,因此建议两根感温电缆之间的安装间距不应超过5m,如增大感温电缆的安装间距,必须充分考虑由此带来的不安全因素。

精心整理线型感温探测器设计安装要求线型感温探测器具有超出其它类型探测器的独特优点,是应用于高风险易燃区和多种类型的工业、商业环境中的理想选择,特别是在具有安装困难和恶劣的条件下使用时,更能体现出传统的点式火灾探测器所不具备的优越性能。

线型感温探测器应根据设置场所的情况选择适宜的类型和安装方式,它是火灾自动报警系统有效和可靠运行的基础,因此线型感温探测器在使用时,必须有专业的设计、安装和完善的管理。

本文以下内容谨做参考。

1.1(1(21.2另外,如果感温电缆的安装间距过大,也不能快速有效的探测中间区域,因此建议两根感温电缆之间的安装间距不应超过5m ,如增大感温电缆的安装间距,必须充分考虑由此带来的不安全因素。

1.3线型感温探测器安装的基本原则(1)线型感温探测器是一种感温火灾探测器,探测器必须以连续方式安装,不能抽头或分支,必须符合国家规范。

(2)线型感温探测器由感温电缆、微机调制器(或接线盒)、终端处理器(或终端盒)组成,三部分必须配套使用。

(3)在感温电缆与微机调制器(或接线盒)连接困难时,可以采用信号电缆进行中间连接,信号电缆的绝缘电阻应大于1500M Ω,信号电缆的内阻不大于100Ω。

当使用此种连接方式时,必须得到我们的认可,以确保使用的安全性。

1.4线型感温探测器安装的基本要求线型感温探测器是一种性能先进的火灾探测器,它所具有的功能可满足易燃区的任何防火要求。

虽然线型感温探测器有很强的抗机械损伤能力,当线型感温探测器在安装时还是应避免机械损伤,在线型感温探测器安装过程中的部分损伤很难从探测器的外表进行分辨,但运行一段时间后可能出现不正常的报故障或报警情况,因此线型感温探测器安装时必须注意:(1)避免将感温电缆上压敷重物;(2(3(4在货架中应用时,可将感温电缆安装在天花板下,沿货架过道中心线布置,也可以和喷水灭火系统管道在一起附设,同时将感温电缆固定在竖立的通风道空间。

货架内有比较危险物品时,感温电缆应安装在每一货架内,但不能影响货架的正常工作,以免存取货物破坏感温电缆。

JTW-LD-85-8687线型定温火灾探测器安装使用说明书
1.概述
JTW-LD-85-8687开关量式线型定温探测器(以下简称探测器)为开关量的感温探测器,报警温度为85℃;该探测器由传感电缆、末端盒两部分组成,该探测器满足GB16280-2005标准,可方便地与其它厂家的火灾报警控制器配套使用。

2.主要技术指标
◆环境温度:-30℃~55℃;
◆最大长期工作湿度:90%~98%,短期可达100% ;
◆工作电压:DC18-32V ;
◆末端盒防护等级IP65。

3.探测器安装
A.基本原则
◆传感电缆必须以连续的无抽头或分支的连接布线方式安装,并严
格按照国家规范要求进行,,如确需中间接头时,必须使用专用的
密封接线盒;
◆探测分区的划分依据规范进行,结合探测区域的特征和环境温
度,决定传感电缆使用长度和回路数;
◆可以方便地与其它厂家的火灾报警控制器配套使用。

B.传感电缆的报警温度等级
根据生产工艺的不同,探测器的报警阀值可以在工厂调定,对于特定的区域选择合适的报警阀值主要取决于以下几个因素:
◆根据防护区域可燃物的燃烧特性,确定和选择报警的温度等级;
◆确定传感电缆使用环境的最高环境温度,以确定不动作温度。

C.传感电缆的布设位置
传感电缆的布设原则上应尽可能靠近防护对象,对于要求探测器在火灾发生以前或产生的热导致设备失灵之前,就能够检测出其温度逐步上升或过热的现象,则更应该采用直接接触式布设。

4.系统接线方式
与报警控制器相接时,接至其输入模块的监视端,接线示意图如下(终端电阻视不同厂家的要求而定);
通用接线方式图。
