2.2.2 Installation Options

Figure 2-7 through Figure 2-8 illustrates various installation options for the Singlewire-enabled

Speaker.

2.2.2.1 Singlewire-enabled Speaker with Extra Speaker Connection

In Figure 2-7, the Singlewire-enabled Speaker supports an amplified audio output for a second

analog speaker. While the total speaker wattage is the same, by connecting a low cost analog

speaker, additional coverage can be realized.

Speaker Setup

When using the second speaker connection, the digital volume control needs to be set to less than

level 8 while making pages. Some adjustment of this value may be required depending on the

specific PoE switch.
