The PA-30 can directly drive up to thirty (30) 8 ohm paging speakers or fifty (50) 70 volt paging speakers. The PA-30 provides loud ringing and paging to electronic key systems 1A2 Key systems PABX s 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 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 is easy to install and eliminates the installation of multiple bells relays and paging cards. The unit comes complete with a power supply and integrated 30 watt amplifier.
