Feedback Eliminators and Page Repeaters
Real-time paging can always create feedback if the
volume is loud enough and the speaker is located
near the paging telephone. Since feedback is so
predictable, it's best to eliminate it right from the
start by incorporating a feedback eliminator/page
repeater into your original layout.
A feedback eliminator works by digitally recording
the page and then playing it after the paging
party hangs up. Since the page is already in digital
memory, the page repeater repeats the page at least
one more time. Most listeners do not recognize their
pages on the first call and multiple manual pages
waste employee time.
The Importance of Zoning
Even when the system is properly designed, paging
can be disruptive. It interrupts conversations, and
is distracting. That's why it's so important to limit
paging to only those areas of a building where the
paged party is likely to be. The best way to do that
is to add zoning to a paging layout.
The diagram below shows a simple 4-zone layout,
with a separate paging zone for the factory, office
area, conference room, and lunch room.

A feedback eliminator/page repeater time shifts the page to
prevent feedback and it automatically repeats the page for
better recognition and response.
