KT9301 Bus Fire Telephone Optical Terminal / Fiber Optic Telephone Host and Subunit / Networked Fire Telephone Host

KT9301 Bus Fire Telephone Optical Terminal / Fiber Optic Telephone Master and Slave Units/ Networked Fire Telephone Host

I. Overview:

1) Application Scope: Works with fire telephone or fire broadcast equipment to achieve long-distance audio data transmission via optical fiber; suitable for urban utility tunnels, subways, tunnels, ports, and other scenarios requiring long communication distances.

2) This device is divided into "Master End KT9301/M" and "Regional End KT9301/S." The "Master End" is typically installed in the main control room, while the "Regional End" is placed in various regional control rooms. The "Master End" and "Regional End" are connected via single-mode optical fiber.

3) The "Master End" and "Regional End" must be used together and connected directly through optical fiber.

4) This device operates on a DC 24V power supply, with a wide input voltage range, making on-site power sourcing convenient.

5) It uses an integrated transceiver laser module, dual-wavelength multiplexing over single-mode single fiber, and features an FC plug-and-play optical interface.

5) This device has a self-test function, allowing for the detection of display components.

6) Compliance Standards: "Fire Alarm Control System GB 16806-2006" and its Amendment No. 1.

II. Main Technical Specifications:

1) Power Supply: DC24V ±10% Current: ≤300mA

2) Analog Signal Interface: Mini-DIN6 interface, must use dedicated cables

3) Optical Interface: FC plug-and-play

4) Operating Wavelength: 1310nm/1550nm

5) Transmission Distance: ≥25km

6) Operating Environment: Temperature 0～40°C, relative humidity less than 95%.
