20 PRS-CSR Remote Call
Station
20.1 Introduction
The PRS-CSR Remote Call Station is used for making
live speech or pre-recorded announcements to any
pre-assigned zones or to execute any pre-defined
actions. The remote call station is connected to the
system through the PRS-CSI Call Station Interface with
a Cat-5 cable. This makes the remote call station
suitable to operate the system from remote sites. See
figure 20.1 for a block diagram of the remote call
station.
The PRS-CSR Remote Call Station is a successor to the
LBB4438/00 Remote Call Station. You can only use the
PRS-CSR in combination with the PRS-CSI Call Station
Interface. You cannot use the PRS-CSR in combination
with the (old) LBB4437/00 Call Station Interface. You
can only use the LBB4437/00 to connect LBB4438/00
and LBB4439/00 remote call stations to the system.
