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 PTK5507 Installation Manual; PTK5507 Touchscreen User Manual.
- 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.
PTK5507 Keybus touchscreen
- Not compatible with Neo HS2TCHP — different bus and enrollment entirely.
- Update user PINs at panel when replacing PTK5507 — local user table may reset per manual.
PTK5507 service
- Not interchangeable with Neo HS2TCHP — Keybus only.
After keypad replacement
Re-assign address, partition visibility, and user PINs per manual — new keypad does not inherit old device programming automatically.
