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.

PCL-422 (accessory — not a communicator)

This product is a remote mounting kit for Corbus communicators. It does not generate panel troubles by itself.

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

PCL-422 installation

• Use only approved coax length and grounding in PCL-422 Installation Manual.

• Communicator FTC after remote mount is almost always antenna/coax, not PCL-422 enrollment.

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

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.

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.
