Connecting Speakers

NOTE: If paging zones use the talkback feature, cabling must be shielded and grounded at the AmpliCenter connector, not the speaker.

Using common industry standard procedures or accepted practices of AT&T for telephone equipment, mount speakers and adjust speaker top for each paging zone and run the appropriate cable for 70 volt speaker systems. Use class 2 wiring, and comply with any local safety codes.

The speakers are wired to the AmpliCenter using either of two methods (figure 3-5). Recommended cable size is 24-22 AWG minimum for

20-watts, 18-20 AWG for 100-watts, and 16-18 AWG for 300-watts, with shielded cable for all speakers with talkback.

Connect speaker wire to 70V output connector on rear of AmpliCenter unit.

If there are long speaker runs, it is recommended to use a larger gauge solid wire.
