一.概述

JTGB-ZW-CF6002点型紫外火焰探测器(以下简称探测器)通过探测物质燃烧所产生的紫外线来探测火灾，适用于火灾发生时易产生明火的场所，对发生火灾时有强烈的火焰辐射或无阴燃阶段的火灾以及需要对火焰作出快速反应的场所均可采用本探测器。该探测器与其他探测器配合使用，更能及时发现火灾，尽量减少损失。

二.特点

l    探测器内置单片机，采用智能算法，既可以实现快速报警，又可以降低误报率。

l    探测器采用继电器型输出方式（常开，常闭可选），可直接控制其它设备。

l    传感器选用高性能进口紫外光敏管，具有灵敏度高，性能可靠，抗粉尘污染、抗潮湿及抗腐蚀能力强等优点。

三.技术特性

1.工作电压：

额定工作电压：DC24V

工作电压范围：DC12V~ DC30V

2.工作电流：

监视电流：≤10mA

报警电流：≤30mA

3.输出容量：

无源常开或常闭（可通过探测器内部PCB上JP1选定为常开-NO或常闭-NC）两种可选输出，触点容量1A，DC24V

4.输出控制方式：

通过探测器内部PCB板上跳线器（JP2）可设置为自锁(LOCK)和非自锁(UNLOCK)。

4.1报警自锁方式：

探测器报警后，锁定报警状态，需断电后方可恢复到正常状态。

4.2报警非自锁方式：

探测器报警后，火警源撤销后，探测器可自行恢复到正常工作状态。

5.上电时间≤3S

6.指示灯：正常时，大约每隔5S闪亮一次，表示监测状态；报警时常亮。

7.光谱响应范围：180nm～290nm

The device is an Ultraviolet-only flame detector designed to detect fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. It detects in the ultraviolet (UV) spectral range for optimized speed of response.
It is fast and capable to detecting the ultraviolet (UV) rays emitted by a burning substance and is used in high hazard applications such as petrochemical plants, munitions factories and other areas where flammable or explosive liquids or solids are handled or stored.
The flame sensor adopts an ultraviolet photosensitive tube, with qualities of highly sensitive, reliable, dust-resistant, corrosion proof and moisture-resistant, therefore is not sensitive in sunlight, dust, oil, tolerance of fume, and humidity. Set in a standard calibration to detect a flames at a distance of 25 meters, which flame created by 2Kg ethanol in a Container of Base 33cmX33cm, Height 5cm.
