TJ101 Fire Telephone Panel | Wall Mounted Two-Bus Fire Fighters Telephone System

3. Product Description

The TJ101 Fire Telephone Panel is the central controller of a dedicated fire fighters telephone system. It uses two-bus communication technology and works together with TJ201 wall-mounted extension, TJ202 hand-held extension and TJ301 fire telephone jack, plus an external DC 24 V power supply, to build a complete fire telephone network in the building.

The panel supports address codes from 1-126 with no duplication, and the address book can be created automatically by extension login or imported from an SD card using address book software. A built-in real-time clock with backup battery keeps time even during power loss, ensuring accurate time stamps for every incident.

During a fire or emergency, the operator in the fire control room can call up to five extensions at the same time, or any extension can lift the handset / plug into a jack to automatically call the panel. The panel automatically records the time, address and voice content of each conversation (up to 24 minutes total) and stores 999 incident records for later query and playback.

All parameter settings are protected by a two-level password system (user / admin), avoiding accidental changes. With a communication distance up to 2000 m, simple two-wire bus wiring and compact wall-mounted housing, TJ101 is ideal for fire telephone systems in office buildings, shopping malls, hospitals, schools, factories, warehouses and other public or industrial facilities that require GB16806-compliant fire emergency communication.
