The JTY-HM-TX3703 linear beam smoke fire detector (hereinafter referred to as the detector) is a coded reflective linear infrared beam smoke detection
The detector must be used with the reflector.
The detector adopts a new and reasonable structure design, and is equipped with a unique laser module and digital tube indication during the debugging process, so that the debugging process is made
Simpler. This detector can be used in shopping malls, fitness centers, gymnasiums, exhibition halls, museums, hotel lobbies, printing houses, garment factories,
Warehouses and other places.
Second, the characteristics
1. Communication mode: non-polar two bus;
2. With automatic compensation function, it can automatically compensate for the influence caused by dust, vibration and other factors to a certain extent, which is improved
reliability of the detector;
3. Simple debugging, with concentric laser module indication, can easily find the optical path, there is a digital tube display, can indicate the reflected light intensity;
4. The sensitivity and distance value can be set through the handheld encoder on site;
5. PCB board full sealing protection process.
6. Support coding and non-coding application modes.
