I. Overview:

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

2) This device can be used alone, or it can be networked with DH9361 panel-mounted fire telephone host via KT9301 series optical transceivers, or directly networked with the same model DH9361/BG wall-mounted host via fiber optic, so as to realize functions such as call/talk between the main control room and regional control rooms or each regional slave.

a. System networking devices include: DH9361/BG fire telephone host, DH9361 fire telephone host, KT9301 series audio data optical transceivers, DH9272 series fire telephone slaves, 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 17 fire telephone hosts and 1683 telephone slaves;

d. The regional host can be set via the menu as "non-transfer", "automatic transfer", "delayed transfer" and other modes. When a call comes in from a slave in this region and the local host fails to answer in time, it can transfer the call to the system main host according to the preset mode;

e. When the system is networked, the fiber optic 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, which facilitates construction and debugging.

4) This device can call with slaves in its own region and perform full-duplex calls. The host can communicate with up to 5 slaves at the same time; when used as a "system main host", the system main host can call with each regional host or each regional slave and perform full-duplex calls, and can communicate with up to 5 hosts or slaves.

5) This device has the function of remarking slave locations, 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 slave status in real time. When an open circuit or short circuit fault occurs on the line, or a slave "drops offline", it will send out audible and visual alarms. After the fault is eliminated, it will automatically recover.

7) This device adopts full digital quantity control, each functional unit adopts ARM centralized control, combined with software and hardware technology, 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 operation.

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 components.

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