JTY-GD-F321型点型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-F321型点型光电感烟火灾探测器(以下简称探测器)是两线制开关量型感烟探测器。探测器采用无极性两线制连接，可应用在相兼容的传统开关量报警控制系统和监控报警系统中，也可通过接口模块接入智能火灾自动报警控制系统中。探测器实时监测现场烟雾浓度，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值时，探测器进入报警状态，红色指示灯常亮，回路电流迅速增大。探测器的报警信号以回路电流变化的形式给出，且具有报警锁定功能，报警的复位只能通过短暂的断电来实现。

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、油雾的场所；不适用于正常情况下有烟滞留的场所。

二、 特点及技术指标

1. 工作电压：DC24V（允许范围：DC18V～30V） 2. 工作电流：监视状态＜50µA @ DC 24V

报警状态：1mA～10mA（与回路限流电阻有关）3. 工作指示：监视状态红色指示灯每3 ~ 6秒闪烁一次 报警状态红色指示灯常亮

4. 使用环境：温度：-10℃～55℃

相对湿度：≤95%(40℃±2℃ 无凝露)

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2所示，型号为DZ-F101，外型尺寸为Ø100mm×17mm(直径×厚度)，固定孔直径为Ø4.5mm，固定孔间距为56mm～64mm。探测器与控制器相连接时，采用无极性二线制方式，需使用底座的3端和1端（或2端和1端，2端与3端在探测器内部是直接相连的）；探测器与指示门灯连接时，门灯的负端接底座的4端，门灯的正端接控制器电源的+5V输出。

常用多个探测器的连接方式如图3所示。该级连方式可以判断探测器回路断路或探测器摘除引起的故障。终端电阻的大小与相连接的控制器有关，请参考控制器中相应的说明。

安装与调试的具体方法如下：

1. 按施工图纸，使用2枚M4螺钉，通过图2中所示的C、D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. 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. 将探测器的指示灯（如图1中A处所示）与底座安装标识（如图2中B处所示）对准，再将探

测器插入底座，顺时针方向旋转探测器，直至探测器锁定到位； 5. 待全部探测器安装完毕，且确认无误后，接通控制器电源，探测器指示灯将每3～6秒闪烁一次，

表明探测器已开始工作；

6. 最后使用专用工具或直接吹烟的方式对探测器进行报警测试。探测器报警后指示灯将常亮，同

时控制器给出相应的报警提示信息。测试结束后恢复控制器，使探测器回到监视状态。

四、 注意事项

1. 探测器单独测试时，应在测试回路中串接3K的限流电阻。不允许将直流24V 直接接入探测器，

否则报警测试将导致探测器损坏；

2. JTY-GD-F321型感烟火灾探测器通过JK-02B接入智能火灾自动报警控制系统时，级连数量应小

于15只； 3. 随探测器附带的防尘罩，在现场安装结束未开通使用前，请勿过早摘除，以免探测器受到污染； 4. 探测器安装应符合GB50166-92《火灾自动报警系统施工验收规范》中的规定。

五、 维护与保养

1. 按国家标准GB50166-92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；

3. 从产品出厂之日起一年内，按规定要求正常使用的探测器，如因材料或制造工艺的缺陷而失效，

深圳市泛海三江电子有限公司将负责免费维修或更换。如属人为损坏、使用不当或自行调整、

改动、拆开而导致的探测器失效，不属于保修范围，因此而造成的一切后果，本公司将不负任何责任；

Instruction Manual of JTY-GD-F321 Spot-type Photoelectric

Smoke Detector

I. General

JTY-GD-F321 Spot-type photoelectric smoke detector (Detector hereunder) is a two-wire switch-type smoke-sensing detector. As a non-polar two-wire connection is adopted in the detector, it is compatible in conventional switch-type alarm control systems and monitoring alarm systems. The connection can also be connected with automatic fire alarm control systems via the interface module. The detector monitors smoke concentration in the workplace in real time. While monitoring, the red indicator blinks and the working current is low. When the work site smoke concentration has exceeded the preset alarm threshold, the alarm detectors and the red indicator remain on, while the loop current is increased. The detector’s alarm signal can be locked and is displayed by changes in the loop current. The alarm can only be reset by the instant power disconnection.

The detector is applicable in places where fire might generate volume smoke, i.e. in industrial and civil buildings such as in the restaurant, hotel, teaching building, office building, computer room, archives and stack room.

II. Features and technical parameters

1. Working voltage: DC24V (allowance: DC18V ~ 30V) 2. Working current: during monitoring ＜50µA @ DC 24V

In alarm mode 1mA~10mA (depends on the loop current limiting resistance)

3. Working indicator: during monitoring, the red indicator blinks once per 3~ 6s

In alarm mode: the red indicator remains on

4. Environment: temperature: -10℃~55℃

Relative humidity:≤95% (40℃±2℃ noncondensing)

5. Exterior size: as shown in figure 1, Ø100mm×46mm (its height with the seat is 50mm after installation) 6. Weight: 100g

7. Standard: GB4715-2005

8. Distance from floor: ≤12m

9. Areas covered: see the provisions in the GB50116-98 Fig. 1 Code for Design of Automatic Fire Alarm System.

III. Installation and commissioning

Determine the location, mounting distance and numbers for mounting the detectors in the protection area in accordance to the relevant stipulations of GB50116-98.

A DZ-F101 seat shown in figure 2 is required for mounting the detector; its exterior size is Ø100mm×17mm, diameter of the fixing hole is 4.5mm and the distance between the holes is 56mm~64mm.

A non-polar two-wire system is used to connect the detector with the controller, and terminal 3 and terminal 1 shall be used (or terminal 2 and terminal 1, since terminal 2 and terminal 3 are connected directly inside the detector). When you connect the detector with the door lamp, the negative terminal of the door lamp shall be connected with terminal 4 on the seat while the positive terminal of the door lamp is connected with the +5V output of the controlling power supply.

For connecting multiple detectors, see figure 3. From the connection at this level we can find the failures caused by the connection loop open or caused by dismounting the detector. The terminal resistance depends on the controller; for details see instructions attached with the controller.

Details of the installation and commissioning are as following：

1. Prepare the shop drawing and fix the auxiliary seat onto the defined location with two 4M bolts installed

through the two fixing holes (C、D shown in figure 2).

2. Disconnect the power, connect all seats correctly as per the shop drawing, and then connect the

controllers to the corresponding input ports.

3. Make sure that all detector types correspond with the ones noted in the shop drawing.

4. Align the indicator of the detector (A shown in figure 1) to the mark of the seat (B shown in figure 2)

and insert the detector into the seat; turn the detector clockwise until it is locked.

5. Don’t power on the controller until all detectors have been mounted correctly; the red indicator of the

detector blinks once every 3~6s, which indicates that the detector has started working.

6. Alarm test of the detector is performed by special tool or puffing smoke directly. The indicator latches

on after the detector alarms. After testing reset the detector to monitoring state.

IV. Attention

1. When you test the detector separately, a 3K current limited resistance shall be connected to the test loop.

Don’t connect the 24V DC with the detector directly, otherwise, the alarm test will damage the detector. 2. The connected detectors shall be 15 units max when the JTY-GD-F321 photoelectric smoke detector is

connected with the automatic fire alarm control system via the JK-02B.

3. Don’t remove the dust preventive hood attached to the detector until it is completely mounted to prevent

contamination.

4. The detector shall be mounted as per the provisions of the GB50166-92 Code for Construction and

Acceptance of Automatic Fire Alarm System

V. Maintenance

1. In according to the GB50166-92, detectors shall be tested every 6 months; for detectors that have been

mounted and are working, biennial cleaning and maintaining is recommended.

2. The working environment greatly influences the serviceability of the detector; when the detector is

mounted in a dust prone area, the detector maintenance shall be done in shorter intervals.

3. Failed detectors caused by material or defected processes will be repaired or replaced within one year

from the date delivered from this factory; as long as they were used for the designed purpose. Our warranty excludes detector failure caused by intentional damages; misuse, unauthorized adjustments, modifying or disassembling and we are not responsible for any consequences caused by above behaviors.

4. We are responsible for repairing the products that are not included in the warranty; we are always at

your service if you need. Meanwhile, we do hope to obtain some crucial information concerning the product you are going to repair, such as failure status and possible causes, so that we can find out the problem as quick as possible. It is also a reference for developing and improving our products.
