JTY-HM-GST102 line beam smoke fire detector installation and use manual, mainly introduces the overview, characteristics, technical characteristics, structural characteristics and working principle, installation and wiring, debugging, precautions, use and operation, common faults and maintenance, maintenance and maintenance, spare parts, and scrap.
The JTY-HM-GST102 is a coded reflective linear infrared beam smoke fire detector from GST. The transmitter and receiver are combined in one housing, and the detector must be used with a reflector; the number of reflectors depends on the installation distance. It connects to a fire alarm controller over a bus and uses a built-in microprocessor for alarm and fault analysis.
The manual covers the detector's features, technical characteristics, structure and working principle, installation and wiring, commissioning, operation, common faults and repair, maintenance, accessories and disposal. It gives site restrictions, mounting height and position guidance, sensitivity and address setting, and maintenance procedures. This manual is written in Chinese.
