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.

Keypad and panel troubles display on this device using **[*, 2] (where supported) or dedicated trouble LEDs. Use the host panel install manual** for full trouble lists — below covers common keypad-specific symptoms.
Common keypad / operator faults
| Display / symptom | Meaning | First checks |
|---|---|---|
| Blank / dead display | No power or bus communication | AC, battery, bus wiring, keypad address, fuse |
| Keypad Tamper | Enclosure opened or tamper switch | Mounting plate, tamper jumper, cover fit |
| Cannot Arm / Not Ready | Open zones or active troubles | [*, 2] trouble scroll; close zones; clear troubles |
| Invalid Code / Access Denied | Wrong user code or authority level | User [5] programming; verify partition assignment |
| Corbus Keypad Missing | Neo/Pro lost keypad on bus | Corbus homerun, [902] enrollment, address duplicate |

| Pro Partition Mismatch | Keypad on wrong partition scope | Pro global vs partition keypad assignment in DLS |
| Cannot Enter Programming | Keypad lacks installer authority | Installer code [*, 8]; partition/global assignment |
Pro HS2LCD(RF)PRO
- Pro-only Corbus addressing — Neo HS2LCD addresses are not interchangeable.
- HS2LCD(RF)PRO transceiver faults mirror Neo ICON-RF but with Pro device limits.
Pro HS2LCD(RF)PRO
Same **[*, 2] trouble scroll as Neo but Pro-only** Corbus addressing. HS2LCD(RF)PRO transceiver faults appear as PowerG trouble before sensor faults.
Panel trouble reference
Keypads display panel-level troubles (AC loss, FTC, zone faults) — fix the underlying circuit or device, not the keypad, when [*, 2] points to panel/comms/zone issues.
