I. Overview:

1) Application Scope: Emergency situations, such as communication between the control room and on-site personnel, fire fighting command, evacuation and rescue, and other special application scenarios; scenarios requiring long-distance communication, such as urban pipe galleries, subways, tunnels, ports, etc.

2) This device can be used independently, or it can be networked with the DH9361 panel-mounted fire telephone host via the KT9301 series optical transceivers, or directly networked with the wall-mounted DH9361/BG host via optical fiber, to realize call/communication functions between the main control room and regional control rooms or each regional sub-host.

a. System networking devices include: DH9361/BG fire telephone host, DH9361 fire telephone host, KT9301 series audio data optical transceivers, DH9272 series fire telephone sub-hosts, DH9273(A) series fire telephone jacks, and other components;

Optional components include: DH9277 bus surge protector, DH9279 bus isolator, KT9302 information editing adapter, etc.

b. When the system is networked, the telephone host can be set as "System Main Host" or "Regional Host" via the menu;

c. When the system is networked, it can include up to 17 fire telephone hosts and 1683 telephone sub-hosts;

d. The regional host can be set via the menu to "No Forwarding", "Automatic Forwarding", "Delayed Forwarding", etc. When a call comes in from a sub-host in this region and the local host fails to answer in time, the call can be forwarded to the system main host according to the preset method;

e. When the system is networked, the optical fiber transmission distance can reach more than 25km (single-mode single-fiber);

3) This device adopts our company's two-bus technology, realizing parallel transmission of power supply, communication and voice signals on two wires, with no polarity requirement during wiring, facilitating construction and debugging.

4) This device can call and perform full-duplex communication with sub-hosts in the same region; the host can communicate with up to 5 sub-hosts simultaneously; when used as the "System Main Host", the system main host can call and perform full-duplex communication with each regional host or each regional sub-host, and can communicate with up to 5 hosts or sub-hosts.

5) This device has the function of recording sub-host location information, which can be input via the keyboard or written into the device via a dedicated tool (KT9302 information editing adapter) through a computer.

6) This device has very complete detection measures, which can monitor the bus status and sub-host status in real time, and can send audible and visual alarms when an open circuit or short circuit fault occurs on the line, or when a sub-host "drops offline". It can automatically recover after the fault is eliminated.

7) This device adopts full digital control, each functional unit adopts ARM centralized control, combined with software and hardware technologies, so it can adapt to various complex environmental applications. It uses silicone keys for control, providing a good hand feel.

8) This device has the function of recording and displaying call and answer times; it can query and display no less than 1000 time records; the system main host can query the time records saved by each regional host via menu operations.

9) This device adopts digital recording technology, which is reliable and has a long service life, with automatic call recording; the recording time of a single device is no less than 120 minutes.

10) This device has a self-check function, which can detect display and sound devices.

11) Implementation Standards: "Fire Linkage Control System GB 16806-2006" and Amendment No. 1.
