Features and Functions
The Model 7245-005 Indoor Remote Subset Amplifier Enclosure provides terminations for the following:
• Connectorized subset cabling • System cabling
• Plug-in remote amplifier • Auxiliary input signals (SmartSeries stations only)
• External speaker(s)
Description of Major Components
For the following discussion, refer to Figure 2, which provides a block diagram of the enclosure. The
Model 7245-005 Amplifier Enclosure can be divided into 3 primary sections. Each of these sections is
described in greater detail below.
Subset Connector
The 24-position subset connector J2 links the remote subset with the amplifier and enclosure. This
interface enables the microphone, receiver, hookswitch, page switch, party line, speaker, and auxiliary
input signals of the subset to be connected to the amplifier and system cabling.
Amplifier Connector
The 16-position amplifier connector J1 and 6-position amplifier connector J3 links the amplifier with the
subset and system cabling. This interface enables the ac power, microphone, receiver, hookswitch, page
switch, party line, page line, speaker, mute, and auxiliary input signals of the amplifier to be connected to
the subset and system cabling.
Terminal Blocks
Terminal blocks TB1 and TB2 provide connection points for the system cable, an 8-ohm or 16-ohm
speaker, and the auxiliary inputs signals. In addition, the terminal blocks provide connectivity to the
subset receptacle and remote subset amplifier connector.
