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

for 20s(Set for each Detector)19.Cleaning the SystemThe system will automatically compensate for dust build-up by changing the Compensation Level.However,it is recommended that the Detector lenses and 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 event•The signal strength when the event occurred (if applicable)•The AGC value when the event occurred (if applicable)2.Event Logger(continued)Press left to access olderevents,and right to

auto-repeat function on any key.To move the motor in any given direction more than once, press the key multiple times4.Cover the Reflector.If the Signal Strength does not drop by more than half,the

普通感烟探测器与智能型感烟探测器的区别

普通感烟探测器与智能型感烟探测器的区别图1 JTY-GD-G3型感烟探测器首先看一下国内火灾报警行业的老大海湾的JTY-GD-G3型火灾探测器,内部是板号为F7.820.1336的一块板子和防尘罩组成,其电路板图片如上图所示,这块板子从电路板工艺来说,电路元件装配使用表面安装技术(SMT),板面上面有个八位单片机存储器,是探测器板的核心部件,通过在探测器内部固化的运算程序,用于对外界环境参数变化进行判断,但由于存储器容量有限,在实际使用中还是由主机来维持整个系统的运算图2 JTY-GM-LA1550A型感烟探测器图2是深圳泰和安的JTY-GM-1550A型感烟探测器从做工上面看制造工艺要比海湾稍逊一些,单片机存储器看其管脚数量要比海湾的存储量稍大,结合泰和安第三代平衡总线技术的特点,较一般厂家的探测器智能,对现场环境参数可进行自动补偿,但在实际使用中的稳定性及其外壳防护等级较业内其它厂家的产品来说也有待提高进口产品:安舍牌感烟探测器以上是国产火灾报警阵营内的主力军,我们再来看看进口火灾报警产品的特点,安舍火灾报警系统是世界最先进的安全防灾系统之一,拆开探测器一看果然很有内涵,其内部电路如图3所示,探测器有内置CPU,拥有对报警浓度作出自我检测功能及及时作出报警反应,这样可以避免探测器和控制器之间进行不必要的数据通讯,和传统国产的探测器相比,这种探测器对主机的依赖大大下降,减轻了主机的工作量,提高了整个系统的稳定性,真正实现了分布智能,另外进口品牌大多使用环形布线方式,虽在线路长度上面要比国产的树形总线要长,但是由于进口设备功耗极低(就普通探测器而言,为国产的一半),其线径可以大大缩小,当然进口探测器占据着高端市场,其价格相对国产探测器来说也是比较高的。
国产:JTY-GD-AHG992001新沃牌感烟探测器在师傅那里我还看到了工艺及技术和安舍感烟探测器有异曲同工之处的火灾探测器,我还以为也是安舍一个系列的探测器,没想到师傅说这个是国产的,是西安一家名叫新沃科技的公司生产的,让我惊讶的是国内原来也有技术性这么强的火灾报警厂家,师傅说新沃科技原来是安舍在中国的合作伙伴,后来安舍退出了中国市场,安舍的先进技术在新沃的新产品中得以保留,新沃现在的环形总线技术、分布智能在国内同行业中都是具有相当的优势的。

感烟火灾探测器JTY-GD-G3设计使用说明书
一、特点
JTY-GD-G3型点型光电感烟火灾探测器采用无极性信号二总线技术,可与海湾公司生产的各类火灾报警控制器配合使用。
本探测器主要具有以下特点:
(1)内置带A/D转换的八位单片计算机,具备强大的分析、判断能力,通过在探测器内部固化的运算程序,可自动完成对外界环境参数变化的补偿及火警、故障的判断,存储环境参数变化的特征曲线,极大提高了整个系统探测火灾的实时性、准确性;
(2)采用电子编码方式,现场编码简单、方便;
(3)采用指示灯闪烁的方式提示其正常工作状态,可在现场观察其运行状况;
(4)底部采用密封方式,可有效防水、防尘、防止恶劣的应用环境对探测器造成的损坏;
(5)专利产品,专利号为ZL99311724.4。
二、主要技术指标
(1)工作电压:总线24V
(2)监视电流≤0.6mA
(3)报警电流≤1.8mA
(4)报警确认灯:红色,巡检时闪烁,报警时常亮
