What this device does in the system

Extends panel capacity (zones, outputs, wireless, power, or reporting) — plan bus address, current draw, and device limits before install.

Before you install or replace one

  • Confirm exact model number on the label matches the install manual.
  • Verify host panel or system family — Keybus, Corbus, Combus, PowerG, MX, or 433 MHz are not interchangeable.
  • Check device limits on the panel/receiver before adding zones, sirens, or credentials.
  • Include current draw in power budget calculations for modules, receivers, and keypads.
  • For wireless: test RF at the mounted location, not only on the bench.

FAQs

Which panels or systems does Telephone Interface & Automation Control Module work with?

See compatible-peripherals.md for the host compatibility table. Match bus type and wireless generation before ordering.

Why does the panel show a fault after install?

Usually enrollment, wiring, power, or tamper — read the active trouble on the panel ([*, 2] where supported) before replacing hardware.

Can I use this on a different brand panel?

Only if the install manual explicitly lists cross-brand compatibility — most DSC devices are family-specific.

Where is the official documentation?

How do I test after installation?

Complete walk test, supervision test, and (for wireless) placement test at the final mounted location — bench tests miss range issues.

How many modules can I add?

Limited by panel device count, bus current, and expander slots — sum AUX draw before adding hardware.

Can I mix expander revisions?

Often no — e.g. PC5108 v1 and v2 must not mix on PowerSeries; verify manual revision table.
