5．待全部探测器安装完毕，且确认无误后，接通探测器电源，探测器指示灯首先按 1秒1次的频
率快闪，然后进入正常监视状态每 3～8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、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. 探测器附带保护罩如图 7 所示，在现场安装未使用前，请勿摘除，以免探测器受到污染。
图 7
4. 探测器并联使用时，要保证多个探测器在同时上电情况下，最大上电电流不要超过主机检测的报
警电流门限, 建议级联数量小于 5只。
5. 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；探测器至空调送风口边的水平距离不应小于 1.5m，

6. 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 9所示。
图9
7. 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。
图 10
8. 探测器安装在具有送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 11 所示。
图 11
9. 当探测器必须安装在送风口附近时，必须保持一定的距离，如图 12 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。
图 12
10. 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。

Instruction Manual of JTY-GD-S839 Point-type Photoelectric Smoke Detector
Read through these instructions before using this device to ensure correct installation and use!
I. General
JTY-GD-S839 point-type photoelectric smoke detector is a two-wire switch-type smoke 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 smoke detector 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 detector is alarming 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 sensor has an automatic
compensation function against dust accumulation and can reduce the effect of dust on the sensitivity of the sensor.
The smoke 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. The smoke detector is not applicable in places, i.e. there is dust, aggressive gas, inflammable gas, oil mist,
vapor, or salinity etc in the environment.
II. Features and technical parameters
1. Working voltage: DC12V/24V (allowance: DC9V ~ 27V)
2. Working current: Power on ＜250µA
During monitoring ＜50µA @ DC 12V & ＜80µA @ DC 24V
In alarm mode 1mA~20mA @ DC 12V (Depends on DC input voltage and the
resistance for measuring alarm current in power input loop)
3. Working indicator: During monitoring, the red indicator blinks once per 3 s ~ 8 s.
In alarm mode, the red indicator remains on.
4. Environment:
temperature: -10℃~+55℃
Relative humidity:≤95%
(40℃±2℃non-condensing)
5. Exterior size: as shown in figure 1,
75mm×51mm×31mm (with the base)
6. Weight: about 50g
7. Distance from floor: ≤12m
8. Areas covered: see the provisions in the GB50116-98

Details of the installation and commissioning are as following：
1. Installed base can be used as follows：
a) Prepare the shop drawing and fix the auxiliary base onto the defined location with two M4 bolts
installed through the two fixing holes (A、B shown in figure 2).
b) Magnet install into designated A, B fixed hole as shown in figure 2 , after the base and
c) the detector assembly, adsorbed detector on the metal cabinet or rack through the magnet;
d) According to the shop drawing, use a drill to bore two Φ6mm holes onto defined location, then put
two expandable plastic stoppers into the holes separately, fix the auxiliary base onto the defined
location with two ST3.5×20mm tapping screws installed through the two fixing holes (A & B
shown as below figure).
2. Disconnect the power, connect all bases correctly as per the shop drawing, and then connect the
controllers to the corresponding input ports.
3. Make sure that all smoke detectors types correspond with the ones noted in the shop drawing.
4. To be installed and disassembled the smoke detector, as shown in figure 5 and figure 6.
5. Don’t power on the controller until all smoke detectors have been mounted correctly; to confirm correct,
connect detector power supply. First, the red indicator blinks by 1 second frequency, and then enter the
normal state to monitor every 3 ~ 8 seconds blinks once, indicating that detectors have begun working;
6. Alarm test of the detector is performed by special tool or puffing smoke directly. The red indicator
remains on after the detector alarms. After testing reset the detector to monitoring state.
IV. Precautions for engineering installation
1. Check that the sensor type matches that indicated in the construction drawing.
2. Calculation of protection area and installation quantity of sensors. The protection area is about 60m2
when the space height is 6~12m; The protection area is about 40m2when the space height is below 6m.
3. The protective cover attached to the sensor is shown in figure 7. During onsite installation before use, do
not remove the cover to prevent the sensor from being contaminated.

4. When the sensors are used in parallel, ensure that when multiple sensors are energized at the same time,
the maximum power current does not exceed the alarm current threshold detected by the main machine,
and it is suggested that the connection quantity be less than 5.
5. The sensor installation shall comply with relevant stipulations in the national standards GB50116-98
“Code for design of automatic fire alarm system” and GB50166-2007 “Code for installation and
acceptance of fire alarm system”, for example, the horizontal distance from the sensor to the wall-beam
edge shall be no less than 0.5m; there shall be no materials within 0.5m around the sensor; the
horizontal distance from the sensor to the edge of the AHU air inlet shall be no less than 1.5m, and that
to the opening of the perforated air supply ceiling shall be no less than 0.5m, etc.
6. When the sensor is installed within the cabinet, there shall be certain clearance between the sensor and
the inner wall of the cabinet, and there shall be no materials within 0.2m around the sensor, as shown
in figure 9.
7. The smoke sensor shall not be mounted above an electric heater or heat radiation fan or within the air
duct or air chamber, since dust and condensation are easily generated at such places, leading to an
error reporting of the sensor.
8 . When the smoke sensor is mounted in the room with air supply and air return ducts, such sensor shall
be mounted on the path through which the airflow goes towards the air return duct, as shown in figure
11.
Fig.8

9．When the smoke sensor must be mounted near an air inlet, a certain distance must be kept, as shown in
figure 12. Correct installation position may enable the sensor to fast and accurately detect a fire.
Incorrect installation position may cause the sensor to be slow to alarm or even issue a false alarm due
to the interference of the high-speed air flow from the air duct.
10．The wiring of the smoke sensor shall meet relevant electric design codes in the national standard
GB50116-98 “Code for design of automatic fire alarm system”, for example, the lines for fire control,
communication and alarm shall be protected with metal pipes and hidden within non-combustible
structures; lines of different systems, different voltages or different currents may not be laid within one
pipe or the same slotted hole; the cable shaft of light current circuit and that of heavy current circuit
shall be arranged separately. If they must be used together due to condition limitations, the light current
circuit and the heavy current circuit shall be respectively arranged at both sides of the shaft, etc.
V. Maintenance
1. In according to the GB50166-2007, smoke detectors shall be tested every 6 months; for smoke detectors
that have been mounted and are working, biennial cleaning and maintaining is recommended.
2. The working environment greatly influences the serviceability of the smoke detector; when the smoke
detector is mounted in a dust prone area or in high speed wind environment, the detector maintenance
shall be done in shorter intervals.
3. Failed smoke 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 smoke detector failure caused by intentional damages; misuse, unauthorized
adjustments, modifying or disassembling and we are not responsible for any consequences caused by
above behaviors.
