Overview

3G8080 (HSPA) and CD8080 (CDMA) cellular modules report PowerSeries Neo alarms over mobile networks as Corbus alternate communicators.

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
Module supervision (Neo/Pro)	Corbus communicator missing	Corbus wiring, enrollment `[902]`, module address

3G8080 / CD8080

CD8080 CDMA sunset varies by carrier — registration fault may require LTE module migration (TL880/LE2080).

3G8080 HSPA: verify HSPA network still available in deployment area.

3G8080 / CD8080 cellular module

Condition	LED / display	Action
HSPA registration	Flashing registration LED >10 min	SIM, APN, carrier sunset
CDMA registration (CD8080)	Solid error	CDMA sunset — migrate to LTE module
Corbus fault	Panel module missing	Wiring, `[902]` address

No Ethernet path — all diagnostics are cellular registration + panel Corbus supervision.

LED / module diagnostics

Troubleshooting

Start with host panel identification, then communicator model, then reporting path (POTS, IP, cellular, dual-path).

Quick diagnostic flow

Confirm communicator model matches 3G8080-CD8080 Installation Manual v1.1.

Verify host panel is on the supported list in compatible-peripherals.md.

Read active troubles on the panel keypad or installer interface.

Test physical path (Ethernet link, SIM registration, dialer voltage) independent of zone programming.

Run communication test to central station after local troubles clear.

Verify account and receiver programming matches programmed phone number, IP, or cellular destination.

Power and supervision

Corbus/Keybus modules: check AUX/Corbus voltage and enrollment in installer programming.

Universal dialer-capture: verify Tip/Ring seizure and ~50 VDC on line when panel is idle.

Dual-path: test each path independently before relying on backup failover.

Network / cellular

IP: ping gateway, confirm firewall allows outbound to receiver, check cable and link LEDs.

Cellular: confirm SIM active, APN correct, RSSI acceptable at install location; use antenna extension kit if enclosure blocks signal.

3G modules: verify carrier has not sunset 3G in your area — plan LE4010/TL880 LTE migration where required.

Neo cellular-only modules

No Ethernet path on 3G8080/CD8080 — all FTC diagnosis is SIM, APN, RSSI, and receiver account.

3G8080 service

Check Module Status in DLS for HSPA/CDMA registration text before RMA.
RSSI field in status screen — relocate antenna or add PCL-422 remote mount if low.

After panel swap

Re-enroll the communicator on the new panel, re-download programming, and re-test all reporting paths — communicators are not hot-swappable across panel families without reprogramming.

Installation Notes

Follow 3G8080-CD8080 Installation Manual v1.1 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

Mount communicator (or PCL-422 remote mount if used) per manual clearances.

Wire power and data: Corbus/Keybus homerun, dialer Tip/Ring, or Ethernet as applicable.

Enroll module in panel programming (Neo/Pro [902], PowerSeries alt-comms section, IMPASSA [382]/[401] as applicable).

Program reporting codes, account, and path priority (primary/backup for dual-path).

Run end-to-end communication test and document signal levels.
