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.
