JTY-HM-TX3703 linear beam smoke detector (hereinafter referred to as the detector) is a coded reflective linear infrared beam smoke detector The detector must be used in conjunction with the reflector. The detector adopts a new and reasonable structural design, and is equipped with a unique laser module and digital tube indication during the debugging process, making the debugging process more concise. This detector can be used in shopping malls, fitness centers, gymnasiums, exhibition halls, museums, hotel lobbies, printing factories, garment factories, Warehouses and other places. 2. Features 1. Communication mode: non-polar two bus; 2. With automatic compensation function, it can automatically compensate for the influence caused by factors such as dust and vibration to a certain extent, which improves the the reliability of the detector; 3. Easy to debug, with concentric laser module indication, it is easy to find the optical path, and there is a digital tube display, which can indicate the intensity of reflected light; 4. The sensitivity and distance value can be set by hand-held encoder on site; 5. The PCB board is fully sealed and protected. 6. Support coding and non-coding two application modes. 3. Technical parameters 1. Operating Voltage: Bus: 15~28V Power: DC 20V~28V 2. Working current: Bus current: ≤2mA Power supply current: monitoring current ≤23mA Alarm current≤33mA Debug current≤55mA 3. Optical path orientation dependence angle: ±0.5 degrees (the data take the average value of the left and right minimum deflection angles) 4. Response threshold: 2.3dB±0.5dB 5. Sensitivity level: 3 levels in total Level 1 sensitivity: the highest sensitivity Secondary sensitivity: medium sensitivity Three levels of sensitivity: the lowest sensitivity 6. Coding method: electronic coding (coding range is 1~254) 7. Fire alarm and fault contact output (the output terminal is invalid in encoding mode): Fire alarm relay: contact capacity 30V/2A, terminals HJ1 and HJ2 are normally open under normal conditions, and closed under fire alarm conditions. Fault relay: contact capacity 30V/2A, terminals GZ1 and GZ2 are normally open in normal state, and closed in fault state. 8. Operating environment: temperature -10℃～+55℃, relative humidity ≤95%RH, non-condensing. 9. color: gray 10. Enclosure rating: When used in ordinary environments, the enclosure protection level is IP30; When used in special environments, the protection level of the shell is IP66 after being sealed with glue. 11. Optical path length: 8m ~ 100m 12. Weight: Approx. 476g 13. Executive standard: GB 14003-2005
