Telephone System Interface

Telephone Mode Switch

The AmpliCenter, when used without a PagePac Plus Controller, connects directly to your facility telephone system for paging. Figure 3-6shows this interconnection. Be sure the Telephone Mode Switch on the rear of the AmpliCenter is set to the type of telephone system you have (see next paragraph).

When used with a PagePac Plus Controller, the AmpliCenter receives its telephone paging input from the controller. Figure 3-6illustrates this interface, as well.

The connection between the AmpliCenter and the page input interface has four possible modes of operation to accommodate a variety of telephone systems. They are as follows:

■Dry loop, 600 ohms

■Dry loop, Hi Z

■Ground start

■Loop start
