DSC HSPA Universal Wireless Alarm Communicator

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.

Reporting path

Universal HSPA — panel-agnostic dialer capture

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

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

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

LED / module diagnostics

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

Quick diagnostic flow

1. Confirm communicator model matches 3G4000 v4.0 Installation Manual / Installation Guide.

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

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.

3G4000 service

• Panel-agnostic HSPA dialer capture — not for Corbus/Keybus direct mount.

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.

Host panels & systems

Related accessories

• RJ-31X or equivalent line-seizure jack
• Monitoring receiver accepting 3G4000 supervision

Not compatible

• Direct Keybus/Corbus module slot installation
• Panels without dialer output or with IP-only reporting

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 3G4000 v4.0 Installation Manual / Installation 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.

Regional notes

Which panels does this communicator work with?

See compatible-peripherals.md for the host panel table. This communicator is not universal unless explicitly listed as panel-agnostic dialer capture (3G4010, LE4000, TL300 universal families).

Is this the same as a T-Link receiver?

No. Communicators send signals from the premises panel; Sur-Gard/T-Link receivers accept signals at the central station. Both must be compatible with your monitoring path.

Why does the panel show FTC after install?

Failure to Communicate means the panel could not complete a successful report — check wiring, account programming, receiver availability, and format (Contact ID/SIA) before replacing hardware.

Can I move this communicator to a different panel brand?

Only universal dialer-capture units (3G4010, LE4000, etc.) are designed for multi-brand use. Panel-bus modules (GS2060, TL280, TL880, TL250) are family-specific.
