JTY-GD-S832 点 光电感烟火灾探测器使用说明书
安装、使用前,请仔细阅读本说明书
一.概述
JTY-GD-S832 型点型光电感烟火灾探测器(以下简称探测器,外观如图 1
所示)采用无极性电源输入,能够探测火灾时产生的烟雾及时发出报警信号。探
测器采用了 CPU控制,能够智能判断火灾时产生的烟雾浓度。探测器处于监视
状态时,红色指示灯闪烁,工作电流小;当现场烟雾浓度超过设定的报警阈 时,
探测器进入报警状态,红色指示灯常亮,同时继电器动作。探测器带有继电器干
接点输出,报警信号以继电器触点动作变化的形式给出,且具有报警锁定功能,
报警的复位只能通过短暂断电来实现。探测器具有灰尘积累自动补偿功能,能 减
少灰尘对探测器灵敏度的影响。
探测器适用于火灾发生时有大量烟雾产生,而正常情况下无烟雾的场所,
如:饭店、宾馆、教学楼、办公楼、计算机房、通讯机房、书库和档案库等工业
与民用建筑。但不适用于有大量粉尘、水雾滞留的场所;不适用于可能产生蒸汽
和油雾的场所;不适用于正常情况下有烟滞留的场所。

三.安装与调试
按照国家标准 GB50116-98 中的相关规定和要求确定保护区域中探测器的
安装位置、安装间距和数量。
探测器的安装需要使用配套底座。配套底座如图 3所示,外型尺寸为 75mm
×51.8mm×5mm(长×宽×高),固定孔为 5mm×10mm,固定孔间距为
52mm~66mm。探测器通过4PIN 插拔式端子(见图4)与外界接线,其中 D1、
D2 脚为电源输入端口;K1、K2 脚为继电器输出端口。
图3图4
安装与调试的具体方法如下:
1.底座安装可采用如下方式:
1)按施工图纸,使用 2枚M4 螺钉,通过图 3中所示的 A、B固定孔,
将配套底座固定在指定的位置上,且应确认底座已安装牢靠;
2)按施工图纸,在指定位置上钻 6mm 孔,塞入附带的料膨胀胶塞,
使用 2枚ST3.5×20mm 的自攻螺钉,通过图 3中所示的 A、B固定
孔将配套底座固定在膨胀胶塞上;
3)将指定磁钢装入图 3中所示的 A、B固定孔,底座与探测器装配 ,
通过磁钢将探测器吸附在金属机柜上,此安装方式为选配安装方式。
2.切断控制器电源,按施工图纸,先将所有底座正确连接,再接入控制器相
应的输入端口;
3.确认探测器类型与施工图纸上所注类型相匹配;
4.安装和拆卸探测器见图5和图6:
图5图6
5.待全部探测器安装完毕,且确认无误,接通探测器电源,探测器先闪烁
1次,然进入正常监视状态约每 6秒闪烁一次,表明探测器已开始工作;
6.最使用专用工具或直接吹烟的方式对探测器进行报警测试。探测器报警
指示灯将常亮,同时控制器给出相应的报警提示信息。测试结束 恢复
控制器,使探测器回到监视状态。
7.当探测器安装底座旋到位时,内部终端电阻(47KΩ)会通过底座上导接片接
入继电器输出端口(K1,K2)之间。导接片的安装与拆卸,如图 7和图8所示。
图7图8
四. 工程安装注意事项
1.确认探测器类型与施工图纸上所注类型相匹配。
2.探测器的保护面积及探测器安装数量计算:
空间高度在6~12米时,保护面积约为60平方米;
空间高度在6米以下时,保护面积约为40平方米。

3.探测器安装应符合国家标准 GB50116-98《火灾自动报警系统设计规范》和
国家标准 GB50166-2007《火灾自动报警系统施工及验收规范》中 的 相关规
定,如:探测器至墙壁梁边的水平距离不应小于 0.5m;探测器周围0.5m
内不应有遮挡物;探测器至空调风口边的水平距离不应小于 1.5m,至多
孔风顶棚孔口的水平距离不应小于 0.5m 等,如图 9所示。
图9
4.探测器安装在机柜内部时,要求探测器距离机柜内壁应有一定的间隙,探
测器周围水平距离0.2 米内不应有遮挡物,如图 10 所示。
图10
5.避免把探测器安装在电热水器、机器散热风扇的上方或是装在风道、风室
内。这些场所容易产生粉尘颗粒和冷凝水雾,容易导致探测器误报,如图
11 所示。
6.探测器安装在具有 风和回风管路的房间时,探测器应该安装在流向回风
口的气流流经的路径上,如图 12 所示。
图12
7.当探测器必须安装在风口附近时,必须保持一定的距离,如图 13 所示。
正确的安装位置可以使探测器迅速、准确地探测到火灾。相反,不正确的
安装位置,不但使探测器报警缓慢,而且探测器还容易受到风口的高速气
流的干扰而产生误告警。
8.探测器的布线应符合国标《火灾自动报警系统设计规范GB50116-98》中
相关的电气设计规范,如:消防控制、通讯和报警线路应采取穿金属管保
护,并宜暗敷在非燃烧体结构内;不同系统、不同电压、不同电流类别的
线路不应穿于同一根管内或线槽的同一槽孔内;弱电线路的电缆竖井宜与
强电线路的电缆竖井分别设置。如受条件限制必须合用时,弱电与强电线
路应分别布置在竖井两侧等。
五. 维护
1.按国家标准 GB50166-2007《火灾自动报警系统施工及验收规范》的要求,
探测器每半年至少测试一次;已安装使用的探测器,建议每二年进行一次清
洗、维护。
2.工作环境的好坏对探测器的性能有很大的影响,对在容易产生灰尘、高风速
等影响正常使用的环境下安装使用的探测器,应缩短其维护保养的周期。
