奥瑞那集团光子技术有限公司OT502 使用说明书 V3.0
1.0 概述1.1 JTY-GD-OT502点型光电感烟火灾探测器(以下简称探测器)是我公司成功研制的新一代智能火灾探测器，该探测器采用红外散射原理设计，内置先进的MCU 微处理器，具有现场参数采集，自动检测探测器两端电压等功能，制造工艺采用先进的SMT 贴片技术。
完善的屏蔽措施，对电磁环境恶劣场所有着很好的抗干扰能力。
同时也采用了防潮湿、防腐蚀、防霉变等措施,对沿海高潮湿地区有着很好的防护能力。
1.2 该探测器采用电子编码方式编址，编址后与我公司生产的OZH4800等火灾报警控制器配合使用，探测器正常工作时，绿灯闪亮，当检测到火警信号时红灯常亮。
1.3 该产品为红外光电型感烟火灾探测器。
2.0 结构特征及工作原理2.1壳体材料和颜色采用ABS 复合塑胶设计成型，外观美观、安装方便.2.2工作原理、工作特性该探测器原理是通过红外光线传感器来测量烟的浓度的，探测器的迷宫在结构设计时红外光束是偏离传感器的。
当烟雾进入到迷宫内，烟雾粒子会将部分光束散射到传感器上。
若烟雾的浓度逐渐增加，就会有更多的光束被散射到传感器上。
在到达传感器的光束达到一定的程度探测器就会报警，报警时探测器指示灯常亮，并向控制器反馈火警信号，直到复位控制器为止。
控制器通过检测回路中探测器反馈的火警信号启动控制设备。
2.3 主要部件3.0 技术特征3.1 工作电压：DC20V-30V 3.2 监视电流: ≤350uA报警电流：≤2mA3.3 线制：二线制，无极性3.4 环境条件：温 度 -10℃～+50℃。
相对湿度 ≤95%（40±2℃）3.5尺寸及重量直径:100mm 高度:43.8mm 重量:82g4.0 安装4.1 安装基础、条件及要求4.1.1探测器对烟雾、灰尘、水雾及挥发性气体敏感，因此对那些灰尘大、经常有水雾等场所不适用；另外风速≥5m/s 的风口也不宜安装，因为这些地方烟雾很难积聚。
4.1.2 安装前探测器应保存在防尘、防潮、防霉的地方。

开动，也应在有关人员的严格监视下进行。当输送机检修时，刮
板仍可能通过链轮运载煤和矸石，应格外小心不要站在卸载端和
机尾端的链轮对面。
f) 设备运行时应和运动部件保持一定的安全距离。
g) 当检修设备或输送机运行时，操作人员应注意安全。
链条上进行任何工作都是危险的。
L) 拆卸和更换液压件时，应先释放掉压力。
