The PA-30 can directly drive up to thirty 8 Ohm paging speakers or fifty 70 Volt or 25 Volt paging speakers. This small and lightweight chassis design is possible by utilizing new amplifier technology that is 300% 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, 1A2 key systems, and PABXs, as well as No-KSU phones and multiline phones.

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. Either a loud electronic warble or one of three other soft chime sounds may be selected. An external "night transfer" switch can be added to turn loud ringing on or off in night bell applications.

The PA-30 eliminates the installation of multiple bells, relays and paging cards.
