Introduction

Description

The BP-319/351 are beltpacks for use with RTS 2-wire intercom systems. The BP319 is a microprocessor controlled one-channel intercom, where the BP-351 is a microprocessor controlled two-channel select intercom beltpack. Both have connections for headset/earset microphones (Dynamic/Electret).

Features

Features of the BP-319/351 include:

• 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.

• Microprocessor controlled Microphone Kill Detect.

• Powered externally, via the intercom system power supply on channel one.

• Headset/earset 4 or 5-pin XLR connection set for intercom operation.

Connections and Controls

BP-319/351 has the following connections and controls:

• Intercom volume control

• Headset connectors that accept XLR type 4 or 5-pin male connector.

• Line connector that accepts an XLR type 3-pin female connector for

intercom line and power input.

• A loop-through connection (XLR male) connects several beltpacks in a

chain. Since this is often the preferred method of connection, a line loop connector has been added to new units. See Figure 1 on page 6.
