1 Description and Specifications
DESCRIPTION
General
The BP-319/351 is a portable user station for
use with RTS 2-wire intercom systems. The
BP-319 is a microprocessor controlled one-
channel intercom, where the BP-351 is a
microprocessor controlled two-channel select
intercom belt pack. Both have connections
for headset/earset microphones (Dynamic or
Electret). The factory setting is for Dynamic.
FEATURES
Features of the BP-319/351 include:
1) Call function that allows the user
to send or receive call signals to
other devices on the intercom
channel, including Audible Call
Alert on the listen side.
2) Microprocessor controlled
Microphone Kill Detect.
3) Powered externally, via the
intercom system power supply on
channel one.
4) Headset/earset 4 or 5-pin XLR
connection set for intercom
operation.
CONNECTIONS & CONTROLS
The BP-319/351 has the following connec-
tions and controls:
Intercom volume control.
Headset connectors that accept an XLR type
4 or 5-pin male connector.
Line connector that accepts and XLR type 3-
pin male connector for the intercom line and
power input.
A loop through connection connects several
belt packs in a chain. Since this is often the
preferred method of connecton, a line loop
connector has been added to new units (see
figure Figure 1).

BP-319-351 OPERATION
PROGRAMMING
The BP-319/351 uses four modes of
operation to control the Mic Kill and
Audible Call Alert features (see table 1,
page 8).
Mic Kill:
When this feature is enabled and a Mic Kill
signal is received from the intercom
channel, the BP-319/351 microphone will
be turned off the Mic Kill signal will have
no affect on microphones attached to the
BP-319/351.
Audible Call Alert
When this feature is enabled, an audible
beep is heard in the headset whenever
there is an incoming call from the same
intercom channel.
When this feature is diabled, no audible
beep is heard for incoming calls.
INTERNAL SWITCHES, JUMPERS,
