The Universal Paging Controller Module integrates any KSU/PBX to a standard 70 V Paging system or Decentralized Self-amplified paging system. This unit has inputs for Paging, Back Ground Music, External Chime, Dry Contacts, 90 V common audible, Alarm, and Time Clock. Paging can be initiated via KSU page ports, unused KSU CO line trunks, or from a single line set. The Universal Controller automatically mutes background music during paging, common audible, time clock, and alarm signals. There are 8 selectable ring tones to choose from. This unit is the perfect interface to a standard 70 V paging system which does not have inputs such as ringing, or background music.
