The TJ102 Fire Telephone Panel is the core of a dedicated fire fighters telephone system. It adopts a two-bus communication design and works together with TJ201 wall-mounted extension, TJ202 hand-held extension and ITJ301 fire telephone jack to provide full-duplex voice communication between the fire control room and firemen at each floor or zone.
The panel supports 1–126 address codes with no duplication, and an address book can be created either by automatic login of extensions or by importing data from an SD card. A real-time clock with battery backup keeps time even when power is off, ensuring that the built-in 24-minute voice recorder and 999-event history log store accurate incident information for after-event review.
All configuration operations are protected by a two-level password system (user and admin) to avoid accidental mis-operation. The panel is powered by DC 20–28 V (typical 24 V), provides up to 2000 m communication distance, and is suitable for integration in GB16806 fire alarm & linkage control systems for office buildings, shopping malls, hospitals, schools, factories and other public or industrial facilities.
