At a Glance
| Detail | Value |
|---|---|
| Product type | Alarm keypad / operator interface |
| Model family (HS2ICON, HS2ICN, HS2LCD-ICON-RF, HS2LED) | See label and install manual |
| Bus / wireless link | Corbus (Neo) with optional PowerG transceiver |
| Primary manual | HS2LCD-ICON-RF Installation Manual; HS2LED/HS2ICON Installation Sheet |
| Region / listing notes | RF suffix = integrated PowerG — verify Neo firmware supports transceiver |
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.

Error Codes
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 |
| PowerG Transceiver Fault | ICON-RF transceiver trouble | PowerG enrollment, firmware, antenna |
| Cannot Enter Programming | Keypad lacks installer authority | Installer code [*, 8]; partition/global assignment |
ICON / PowerG transceiver keypads
- PowerG enrollment fault at ICON-RF shows as transceiver trouble before sensor faults.
- Prox P models: reader fault separate from keypad bus fault — check Wiegand/prox wiring.
ICON / PowerG transceiver keypad
| Fault | Source |
|---|---|
| Corbus keypad missing | Bus wiring / address |
| PowerG transceiver trouble | ICON-RF enrollment, antenna, device limit |
| Prox reader fault (P models) | Reader wiring separate from bus fault |
ICON shows icons, not full alpha messages — truncated zone labels vs HS2LCD.
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.
