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.

Troubleshooting
Start with host panel family, then keypad model, then bus vs wireless link.
Quick diagnostic flow
- Confirm keypad model matches PowerSeries Pro HS2TCHPRO Installation Manual; User Guide.
- Verify host panel is on the supported list in compatible-peripherals.md.
- Check power: panel AC/battery healthy before blaming keypad.
- Read troubles at keypad with **
[*, 2]** or trouble LED. - Verify address / enrollment — wired:
[013]Keybus or[902]Corbus; wireless: enroll window and transceiver online. - Test with known-good user code on assigned partition.
Wiring / bus
- Keybus: homerun, polarity, termination; one bad keypad can drag bus if shorted.
- Corbus/Combus: homerun from panel module; check AUX/Corbus voltage under load.
- Wireless: battery, range, antenna, transceiver supervision on panel first.
Pro 7-inch touchscreen
- Black/white bezel is cosmetic — verify HS2TCHPRO model on label for support.
- Uses Pro Corbus enrollment, not Neo
[902]slot limits — check Pro module capacity table.
HS2TCHPRO service
- Black/white bezel cosmetic — verify HS2TCHPRO label for support docs.
After keypad replacement
Re-assign address, partition visibility, and user PINs per manual — new keypad does not inherit old device programming automatically.
