Digital Anti-Feedback Paging Interface

Product Details

Even the best designed paging systems can experience feedback. Now you can eliminate annoying feedback over your paging speakers with Viking’s FBI-1A digital anti-feedback paging interface.

The FBI-1A utilizes state of the art digital recording technology to record the “live” page from a phone system’s paging port output or unused trunk port. The FBI-1A then immediately plays back the recorded page once or twice (selectable) over the paging system. Pages of up to 32 seconds can be stored and the FBI-1A automatically adjusts to the page length for faster processing. In addition, the FBI-1A can be programmed to provide pre-page and post-page alert tones.
