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.

Error Codes
Communicator faults appear on the host panel trouble display ([*, 2] on keypads where supported) and in DLS/dealer tools — the communicator itself may show LED status per its install manual.
Common communicator troubles
| Panel / display | Meaning | First checks |
|---|---|---|
| FTC / Failure to Communicate | Report did not reach central station | Account, path, format, receiver online |
| Alt. Comms AC / Battery | Communicator power fault | Module power wiring, panel AUX budget, battery size |
| Alt. Comms FTC | Alternate path failed | Test primary and backup paths separately |
| TLM / Line fault | Dialer line or seizure issue | Tip/Ring wiring, ~50 VDC idle line, panel dialer programming |
| T-Link Network Fault | IP path cannot reach network | LAN cable, router, firewall, receiver IP |
| T-Link Receiver Trouble | IP path cannot reach receiver | Receiver address, DNS, DSC/T-Link service status |
Universal TL300 IP dialer capture
- Requires Ethernet at communicator — unlike 3G4010, no cellular fallback on base TL300 universal SKU.
- T-Link Receiver Trouble with good link light often means wrong receiver IP programmed in module.
Universal TL300 IP dialer capture
| LED / panel | Meaning |
|---|---|
| Link off | Ethernet fault at module |
| Link on, Receiver Trouble | T-Link receiver IP/account |
| TLM on panel | Dialer capture wiring before IP path matters |
Requires Ethernet at premises — no cellular fallback on base TL300 universal.
