When seconds count in an emergency Midian's PARTI-1 enables remote access to an existing Public Address System via two-way radio with an option for cellular, VoIP and land-line telephone.

  • Live voice messages may be transmitted in real time over PA System
  • The messages that are played over the PA System can be simultaneously played back over the radio channel
  • Input for a remote switch to activate a pre-recorded message

The optional FCC approved telephone interface simply plugs into a wall jack using an RJ-11 connector. The wall jack can be accessed by cellular, VoIP or regular land-line telephone.
