Tanda Reflective Linear Beam Smoke Detector

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 brand-new and reasonable structural design, and is equipped with a unique laser module and  digital tube instructions during the debugging process, so that the debugging process Simpler. 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 dust, vibration  and other factors to a certain extent, which improves The reliability of the detector; 

3. Simple debugging, with concentric laser module indication, easy to find the light path, and digital tube display,  which can indicate the intensity of reflected light; 

4. The sensitivity and distance value can be set through the handheld encoder on site; 

5. PCB board fully sealed protection technology. 

6. Support two application modes: addressable and Conventional mode. Three, technical parameters 1. Operating Voltage: Bus: 15~28V Power supply: DC 20V~28V 2. Working current: Bus current: ≤2mA Power supply current: monitoring current ≤23mA Alarm current ≤33mA Debug current ≤55mA 3. Dependency angle of optical path orientation: ±0.5 degrees (the data is the average 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-level sensitivity: the lowest sensitivity 6. Coding method: electronic coding (coding range is 1～254) 

7. Fire alarm and fault contact output (output terminal is invalid when in coding mode): Fire alarm relay: The contact capacity is 30V/2A. When normal, the terminals HJ1 and HJ2 are normally open and  closed in the fire alarm state. Fault relay: The contact capacity is 30V/2A. When normal, the terminals GZ1 and GZ2 are normally open, and they  are closed in a fault state.

8. Use environment: temperature -10℃～+55℃, relative humidity≤95%RH, no condensation. 

9. color: gray 

10. Enclosure rating: When used in a normal environment, the enclosure protection level is IP30; When used in special environment, the protection grade of the shell is IP66 after the glue sealing treatment. 

11. Optical path length: 8m～100m 

12. Weight: about 476g 

13. Executive standard: GB 14003-2005 

14. Status indication of the detector:
