PA System Telephone Interface RH2818I

The Telephone Interface RH2818I can automatically answer an incoming phone call and broadcast the caller's voice over the PA system and even to individual zones,and a microphone input is provided for talking back to the caller.

By adding a telephone interface to a PA system and being given a fix telephone number,we have introduced the ability to make announcements and paging calls from telephones. Telephones are not special or dedicated functionally in the way that microphones are. They are regular telephones,that might be local to the building, the site, or in fact they can be anywhere,national or even international.
