The TJ301 Fire Telephone Jack is part of the ANWETECH fire fighters telephone system. Installed on the wall in key locations such as staircases, lift lobbies and refuge floors, it provides a robust plug-in socket for hand-held fire telephones.
TJ301 connects to the fire telephone panel (TJ101 or TJ102) through the same two-wire communication bus as the extensions. In normal times it remains in low-current standby; during a fire, the firefighter plugs in a dedicated handset and the system will automatically establish a call with the control room, ensuring fast and clear voice communication.
The jack is designed for standard 86-box wall mounting, with compact dimensions and simple wiring. With low standby current, 30 mA typical operating current and a communication distance up to 2000 m (when used with the panel), TJ301 is suitable for large high-rise projects and complex buildings that require reliable emergency communication at multiple points.
