PA-2A Telecommunication Peripheral Products Paging Amplifier- Loud Ringer Technical Practice July 23, 1998 Add Paging and Multiple Line Loud Ringing to Any Phone System The PA-2A provides loud ringing and paging to electronic key systems, 1A2 Key systems, PABX’s as well as No-KSU phones and multi- line phones. Paging is accomplished by connecting the PA- 2A to a paging port or unused C.O. line input of nearly any phone system. The PA-2A will also generate an adjustable loud warble from up to 6 incoming C.O. lines or from a dry contact closure. An external “night transfer” switch can be added to turn loud ringing on or off in night bell applications. The PA-2A is easy to install and eliminates the installation of multiple bells, relays and paging cards. The unit comes complete with a power supply, amplifier and (1) paging horn. http://www.VikingElectronics.com E-mail...Sales@VikingElectronics.com Features Applications • Two watts of paging power • Amplified loud paging • Sixth line optically coupled for use with fax • Night bell switches • Background music • Ring sensitivity adjustment • Loud ringing • Can provide background music from an external source Specifications • Paging from an unused trunk or paging port Power: 120V AC/13.8V AC 1.25A, UL listed adapter provided Dimensions: 133mm x 89mm x 44mm (5.25” x 3.5” x 1.75”) Shipping Weight: 1.36 kg (3 lbs) • Loud ringing Environmental: 0°C to 32°C (32°F to 90°F) with 5% to 95% non- condensing humidity • Provides loud electronic ring for night bell, Paging Output: 2 watts - powers up to (3) 8 ohm or (16) 45 ohm speakers warehouses, outside yards, etc. Sound Pressure: 110 dB @ 1 meter Speakers: (1) 25AE 8 ohm paging horn included • Output for controlling a 12 volt relay from 1 - 6 Maximum Speaker Run: 91 m (300 ft) maximum 18 AWG ringing lines Connections: (2) RJ25 jacks, (1) 5 position screw terminal block Sales...(715) 386 - 8861 Made in the U.S.A.
