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.

Installation Notes

Follow SG-System II Quick Install Guide for wiring, mounting, enrollment, and receiver programming. Summary below — not a substitute for the full manual.

Pre-install checklist

  • Match communicator SKU to host panel family (see compatible-peripherals.md).
  • Plan mounting location — metal cabinets, underground rooms, and long coax runs affect cellular/IP performance.
  • Reserve panel bus power or external power per manual; update battery calculation chart.
  • Confirm monitoring account and receiver are provisioned before final test.

Typical install sequence

  1. Mount communicator (or PCL-422 remote mount if used) per manual clearances.
  1. Wire power and data: Corbus/Keybus homerun, dialer Tip/Ring, or Ethernet as applicable.
  1. Enroll module in panel programming (Neo/Pro [902], PowerSeries alt-comms section, IMPASSA [382]/[401] as applicable).
  1. Program reporting codes, account, and path priority (primary/backup for dual-path).
  1. Register with central station / Alarm.com / T-Link receiver.
  1. Run end-to-end communication test and document signal levels.
