JTY-GD-DG312 transmission substation smoke alarm using instructions.

Time: 2018-05-08 View: 2842
Substation, where the voltage is changed. In order to put the power of electricity to the distant place, must take the voltage, a high voltage, near to the users according to the need to reduce the voltage again, this kind of work on lifting voltage transformer substation. The main equipment of substation is switch and transformer. Small is called substation by size. The substation is larger than the substation. A JTY- gd-dg312 produced by the armoring letter is specially designed for substations to better protect the safety of substations, as follows:
Please read the installation instructions before loading or using the product. Please keep this manual properly so that you can check it at any time.
Summary of a.
Networking photoelectric smoke fire detector (hereinafter referred to as the detector) with special structure design of the infrared sensor, reliable performance of MCU, and SMT processing production, has a high sensitivity, stable and reliable, low power consumption, beautiful and durable, convenient use, etc. The product is not suitable for use in the following environment:
Under normal circumstances, there is a smoke detention environment.
There are large dust, water mist, steam, oil mist pollution, corrosive gas environment.
Relative humidity is greater than 97% of the environment.
Ventilation speed is greater than 5m/ SEC.
Ii. Working principle.
The detector USES a special structure designed by the photoelectric sensor to combine the reliable MCU, which can effectively detect the initial smoldering phase of the fire or the smoke generated after it is generated. When smoke into the detector, make the light scattering, accept element feel light intensity, the received light intensity and smoke concentration have certain linear relationship, the detector parameters on site constantly gathering, analysis, and judgment, when confirm the intensity of light field data reaches the threshold, the starter relay output. When the smoke in the environment returns to normal, the detector automatically returns to normal working condition. Self-check: under normal condition, the detector carries out internal function test and relay output according to the self-test test button. Note: when the detector alarm, the output relay has no source contact, and the contact capacity is 1A/24VDC.
3. Technical features.
Power supply: DC9V ~ DC46V.
Current: static current is less than 300uA.
Alarm current is no more than 45mA.
Working temperature: - 20 ℃ ~ + 120 ℃
Relative humidity: 97% RH or less (40 ℃ plus or minus 2 ℃)
Output: the relay contact is normally closed and touched.
Capacity of 1 a / 24 VDC,
Smoke sensitivity: 0.15 ~ 0.3db /m.
Iv. Installation and debugging.
(1) make four dates on the wall according to the installation size.
Fixed hole of 6mm;
(2) insert the expansion plug into the fixed hole and screw in.
Self-tapping screw, reserved about 2-3mm gap;
(3) the detector connects the power cord and the signal line first.
The remaining signals can be cut off according to actual requirements;
Connection mode
Red line -- -dc +.
Black wire --DC-.
Connect DC9-DC46V power supply;
White line NC- relay signal normally closed contact;
White line COM- relay signal common end contact.
5. Instructions.
Normal state: the detector turns on 2HZ 5 relay closed/open, and the detector enters the working state.
Self-check status: the detector should self-check periodically. When pressing the button, the detector relay output contact closure; After releasing the key, the detector automatically returns to normal work.
As a state.
Vi. Failure analysis and exclusion.
No output of alarm: check whether the connection is bad or not frequently. There is too much dust in the sensor to clean the labyrinth with a vacuum cleaner (external black plastic part).
Maintenance of seven
In the course of use, please contact with the supplier as soon as possible, and do not disassemble and repair to avoid accident.
If not used for a long time, the detector must be removed, packed in a box and stored in a ventilated and dry place.
8. Transportation and storage.
Transport and storage according to GB/ t15464-1995 general technical conditions for instrument packaging.
In the process of transportation and storage, the original packaging and seal of the production plant must be kept intact, and the product shall not be impacted seriously.

Environmental temperature should avoid drastic changes. The packing height is not more than 6 storeys, and the height of single piece after unpacking is not more than 5.
