Viking PA-30 - amplifier

This small and lightweight chassis design is possible by utilizing powerful amplifier technology that is more inefficient than old designs competitors use. High efficiency means much less heat dissipation, a smaller size, higher reliability, and lower cost. The PA-30 provides loud ringing and paging to electronic key systems. Paging is accomplished by connecting the PA-30 to a paging port or unused telephone line input (trunk port) of nearly any phone system. The PA-30 paging amplifier will also generate adjustable loud ringing from a ringing analog line or from a dry contact closure. The PA-30 eliminates the installation of multiple bells, relays and paging cards.
