Before You Install or Replace One

  • Confirm exact model number on the communicator label matches the install manual.
  • Verify host panel family — Keybus PowerSeries, Neo Corbus, MAXSYS Combus, IMPASSA integrated, or universal dialer-capture are not interchangeable.
  • Confirm monitoring receiver and account accept this communicator format (Contact ID, SIA, IP, cellular).
  • Check carrier/network generation (3G sunset, LTE band, Ethernet path) for your region.
  • Add communicator current draw to panel battery standby calculation where the module loads from panel bus power.
