Optical beam smoke detector Conventional Reflective Beam Detector smoke alarm

JTY-HF-GST102 type linear beam smoke fire detector is a non coding reflection type linear infrared beam smoke detector. The detector must be used in conjunction with the reflector, but it is necessary to use one or four reflectors depending on the distance between the two. The detector has the following characteristics:
The transmitting part and the receiving part are combined into one, and the installation is simple and convenient;
The utility model has the function of automatic calibration, which ensures that the utility model can be debugged by a single person in a short time, and the operation is simple and convenient;
With self diagnostic function, can monitor the internal fault detector;
With automatic compensation function, to a certain extent, the dust pollution, the location of the offset and the aging of the transmitter and other factors that cause the reduction of the received signal can be automatically compensated;
Can be set at the scene of three levels of sensitivity, suitable for different places of dust;
Passive output contact with fire alarm and fault;
The design of the detecting light path is ingenious and the anti-jamming performance is strong;
Seal design, waterproof performance;
Patent product, patent number is ZL03358053.7.
