The PA-2A 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-2A to a paging port or unused telephone line input (trunk port) of nearly any phone system.
The PA-2A will also generate adjustable loud ringing from up to 6 analog lines 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-2A eliminates the installation of multiple bells, relays and paging cards. The unit comes complete with a power supply, amplifier, and (1) Viking 25AE paging horn.
