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.

LTE extension kit (accessory)

Antenna kits do not report to central station. Weak LTE RSSI on host communicator is the symptom they address.

Panel FTC and alt-comms troubles apply to the host communicator, not this accessory — see the communicator listing for full trouble tables.

Antenna extension

• Match kit to communicator family (Neo TL880, IMPASSA TL8055, universal LE4010, etc.) per kit spec sheet.
• After installing extension, re-check RSSI at communicator diagnostic screen before closing install.
• Route coax away from AC/bell conductors; ground per install sheet.

Install checklist

For panel reporting faults (FTC, alt-comms), troubleshoot the host communicator module paired with this product — not this accessory alone.

Host panels & systems

This product does not mount on end-user alarm panels — see Related accessories below.

Related accessories

• LE4000 / LE4010 / LE9080 / TL880LT / TL8055 LTE communicators (verify kit compatibility in sheet)
• Approved antenna and max coax loss per install instructions

Not compatible

• Use without compatible LTE communicator
• IP-only TL280/TL150 paths

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 LTE Antenna Extension Kit Installation Instructions 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.
