Installation of JTY-GD-DG312 smoke alarm in electrical cabinet.

Time: 2018-05-05 View: 2857
DG312 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, apply to the electrical cabinet, can very good protection safety cabinet to prevent the occurrence of fire, the following is how it works:
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-test: under normal conditions, press the self-test button,

The detector carries out its own internal function test, relay output.

Technical characteristics
