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.

FAQs
Which panels does this keypad work with?
See compatible-peripherals.md for the host panel table. Keypads are family-specific — PK5500 does not work on Neo Corbus, and WT5500 is IMPASSA-only.
Why is the keypad blank but the panel has power?
Usually bus wiring, wrong address, or AUX/Corbus undervoltage. Wireless keypads: check battery and enrollment.
Can I use this keypad for programming?
Full-message and touchscreen models typically support **[*, 8, installer code]** where the host panel allows. Fixed LED keypads have limited programming menus.
Can I move this keypad to another panel brand?
Only within the same DSC bus family after full re-address and reprogramming. Never move Keybus keypads to Neo Corbus without replacing the keypad model.
