²        Maximum capacity of single unit: it is can be connected with 15 loops. And the intelligent unit number of each loop connected is not more than 127.

²        Loop automatic identification: the control unit can automatically register and address with intelligent unit on the loop bus without any manual number dialing or electronic encoder.

²        Wiring method: the loop method is the preferred loop wiring one of AHGBUS, and also can be adapt to tree structure wiring.

²        Loop wiring automatic diagnosis: under the loop wiring, the circuitry turnoff can be found to the malfunction point. And the short circuit can be protected by pedestal insulator which makes the systematic loss minimum.

²        Double-end power supply of loop: under loop wiring, even if circuitry suffers short circuit and turnoff, the double-end power supply can be supplied which does not affect the work of non-malfunction unit.

²        Figure and writing display terminal: it takes 10.4’ TFT true color LCD, and WINDOWS interface, and integrate with all the functions of IDT, to provide rich .information presentation and clear and visual operation interface.

²        Multiple operation methods: the touch panel and keypad is supplied; and standard keyboard and mouse with two-level input and operation scheme.

²        Classified alarm windows: the alarm information includes fire alarm, startup, malfunction, incidents and shielding etc which displayed as types. Each kind of messages can reach to ten thousand ones.

²        Historical record storage: it is with black-box function, which can save the latest alarm messages for 1000 ones.

²        Automatic linkage: supplies and/or linkage relation programmed freely by user to realize automatic linkage of fire prevention equipment.

²        Unit shielding: the field unit with problem can be temporarily insulated by software shielding on the Control unit and relieved shielding after problem is settled.

²        Serial ports extension: one serial communication port can be extended out by RS232 serial port card, which can connect with IDT or remote control unit equipment etc.

²        Automatic switch between the main power and spare power: the automatic switch method is taken to ensure uninterrupted run of the system.
