Features and Functions
The 7245-004 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
7245-004 Amplifier Enclosure can be divided into three primary sections. Each of these sections is
described 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 24-position amplifier connector J1 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 - 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.
