VoIP dial-up equipment for PA systems
The 19“ LI140 connects telephones with a PA system. It can be used for industrial applications as well as in the traffic and transportation sector. The VoIP dial-up equipment for PA Systems can be used with a business telephone system with SIP-protocol. The LI140 delivers speech between a telephone and a PA system and automatically answers incoming calls.
A configurable password protects the PA system against unauthorized access. It has to be entered before accessing the system.
Once the user correctly entered the password over the telephone keypad, it is possible to select speakers and use different line arrays. Thereby, several different lines can be used simultaneously. The person calling always ends a call.
Through the serial RS-232 Interface the settings of the LI140 can be changed.
The system uses a voltage of 24V DC.
