Overview
The 3G4000 is a universal wireless alarm communicator that connects to a panel's phone dialer output (Tip/Ring capture) rather than a brand-specific module bus. Works with many manufacturers' panels when wired per guide.

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 |
| Cellular registration / SIM | Module cannot register on mobile network | SIM active, APN, RSSI, antenna placement, carrier sunset |
| TLM / Line fault | Dialer line or seizure issue | Tip/Ring wiring, ~50 VDC idle line, panel dialer programming |
3G4000 HSPA universal
- Same dialer-capture wiring as 3G4010 but HSPA radio — verify carrier HSPA availability (distinct from LTE modules).
3G4010 / LE4010 dialer-capture LEDs
| LED pattern (typical) | Meaning | First checks |
|---|---|---|
| Power solid, Status flash slow | Registering on cellular | SIM, APN, antenna |
| Status rapid flash | Line/seize fault | Tip/Ring, ~50 VDC idle voltage |
| Status off, Power solid | Registered idle | Normal |
| Panel TLM before cellular | Dialer wiring | Seizure, panel dialer programming |
Module captures Contact ID / SIA from panel phone output — panel must dial valid format.
