The available functions of the unit shall be :
Relay :
  • NO and NC relay of 1A contact allows local BGM source overriding, bypass local volume controller to allow central paging to pass through. This is useful during essential paging and whenever 24V DC overriding signal is not available in the cabling works.
  • 100V - Line audio converter
  • ​When it is required that the central paging to be broadcasted to local speakers utilising the local amplifier / system, it provides an audio conversion with balanced line audio.
