I. Overview:

1) Application Scope: Special application scenarios such as communication between the control room and the site, fire fighting command and evacuation rescue in case of emergency; scenarios with long communication distances such as urban pipe galleries, subways, tunnels, ports, etc.

2) This device can be used independently, or it can be networked with devices of the same model via the KT9301 series optical transceivers of our company to realize functions such as call/communication between the main control room and regional control rooms or each regional slave unit.

a. System networked devices include: DH9361 fire telephone master unit, KT9301 series audio data optical transceivers, DH9272 series fire telephone slave units, 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 master unit can be set as "system main unit" or "regional master unit" through the menu;

c. When the system is networked, it can include 17 fire telephone master units and 1683 telephone slave units;

d. The regional master unit can be set to "no transfer", "automatic transfer", "delayed transfer" and other methods through the menu. When a slave unit in this area calls in and the local unit fails to answer in time, it can be transferred to the system main unit according to the predetermined 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 the parallel transmission of power supply, communication and voice signals on two wires, and the wiring has no polarity, which is convenient for construction and debugging.

4) This device can call each other with slave units in this area and perform full-duplex communication. The master unit can communicate with up to 5 slave units at the same time; when used as a "system main unit", the system main unit can call each other with regional master units or regional slave units and perform full-duplex communication, and can communicate with up to 5 master or slave units.

5) This device has the function of noting the location of the slave unit, which can be input via the keyboard or written into the computer using a special tool (KT9302 information editing adapter).

6) This device has very complete detection measures, which can monitor the bus status and the status of the slave unit in real time. When an open circuit or short circuit fault occurs on the line, or the slave unit is "disconnected", it can send out audible and visual alarms. After the fault is eliminated, it can be restored automatically.

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 environment applications. It uses silicone keys for control, with a good hand feel.

8) This device has the function of recording and displaying call and answer time, and can query and display no less than 1000 time records; the system main unit can query the time records saved by each regional master unit through menu operation.

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

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

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

II. Main Technical Indicators:

1) Power Supply: DC24V±10%, Current: ≤1A

Wire: Shielded cable or twisted pair should be used, and the wire diameter should be above 1.5 square millimeters. If the wiring length exceeds 1 kilometer, the wire diameter should be appropriately increased; if a shielded cable is used, the shield layer should be grounded at one end.

Insulation Resistance Between Wires: ≥20kΩ, Capacitance Between Wires: ≤0.7μF

5) Bus Length: ≤1200 meters

6) Recording Time: More than 120 minutes

7) Clock Error: <6s/day

8) Working Environment: Temperature 0～40℃, Relative Humidity less than 95%.
