Before You Install or Replace One

• Confirm exact model number on the keypad label matches the install manual.
• Verify host panel family — Keybus PowerSeries, Neo Corbus, MAXSYS Combus, and IMPASSA wireless are not interchangeable.
• Plan unique keypad address or wireless enrollment — duplicates cause bus collisions or offline devices.
• Check partition assignment (global vs partition keypad) for multi-partition sites.
• Include keypad current draw in panel AUX / Corbus / battery standby calculations.
