DSC Cellular Universal Wireless Alarm Communicator (3G4010 / LE4010)

3G4010 / LE4010 universal wireless communicators provide cellular reporting for virtually any alarm panel via dialer capture or compatible input wiring — independent of DSC Keybus/Corbus.

Reporting path

Universal LTE/3G — panel-agnostic

At a Glance

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.

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

3G4010 / LE4010 universal dialer capture

• Tip/Ring reversal causes immediate TLM before any cellular registration attempt.

• Panel must produce Contact ID or SIA on dialer output — raw voltage triggers without format will not report.

3G4010 / LE4010 dialer-capture LEDs

Module captures Contact ID / SIA from panel phone output — panel must dial valid format.

LED / module diagnostics

Refer to 3G4010 v4.0 / LE4010 v5.x Installation Manual for communicator-specific LED patterns and DLS module status screens.

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

Quick diagnostic flow

1. Confirm communicator model matches 3G4010 v4.0 / LE4010 v5.x Installation Manual.

1. Verify host panel is on the supported list in the Compatible Peripherals section.

1. Read active troubles on the panel keypad or installer interface.

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

1. Run communication test to central station after local troubles clear.

1. 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.

Universal 3G4010 service

• Works across panel brands via dialer capture — not Corbus/Keybus enrollment.

• Confirm ~50 VDC on line when panel idle; seizure must disconnect panel from CO line during report.

• 3G sunset: migrate to LE4010 LTE universal where 3G4010 no longer registers.

3G4010 manual install verification

1. Measure ~50 VDC on Tip/Ring when panel idle (on-hook).
2. Trigger panel test report — verify seizure disconnects house phones.
3. Confirm registration LED steady before closing FTC on panel.
4. Migrate to LE4010 where 3G registration LED never stabilizes (3G sunset).

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.

• Upgrade path from GS3055/GS3060 (2G) per DSC upgrade sheet
• LE4010 LTE successor to 3G4010 where 3G sunset

Not compatible

• Enrolling as Neo Keybus module
• Enrolling as PowerSeries Keybus module (use family-specific GS2060/TL2603G instead)

Central station / receiver notes

Universal and T-Link products require a monitoring receiver that accepts the communicator's protocol and supervision. Confirm with your central station before install.

Follow 3G4010 v4.0 / LE4010 v5.x Installation Manual 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 the Compatible Peripherals section).

• 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.
