Targeted Communication
The PI35A and SI35A allow background
music to play, without interruption, in se-
lected areas while one or more rooms
communicate directly with the main unit.
This feature is useful in a number of ap-
plications, including:
Schools: A live news broadcast can be
played over the system into all rooms. If
an administrator needs a student, the call
for the student can be placed directly into
the classroom the student is in, without
interrupting the live news broadcast to all
the other classrooms.
Medical Center: If a nurse at the main
desk needs to communicate immediately
with one of the physicians, the nurse can
call directly into the exam room where
the physician is without interrupting the
background music being played in all pa-
tient areas. This keeps the physician’s de-
mand and schedule private, so patients
do not become concerned about the
length of their wait before they get to see
the physician.
Connects To Existing Phone Systems
With the WMT1A Line-Matching Trans-
former, a connection can be made to the
page port from the phone system. This
allows an All-Call/Emergency notice to be
made using the in-house phone system.
