Corbus (PowerSeries Pro)

At a Glance

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

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.

Start with host panel family, then keypad model, then bus vs wireless link.

Quick diagnostic flow

1. Confirm keypad model matches PowerSeries Pro HS2LCD(RF)PRO Installation Manual.
2. Verify host panel is on the supported list in compatible-peripherals.md.
3. Check power: panel AC/battery healthy before blaming keypad.
4. Read troubles at keypad with **[*, 2]** or trouble LED.
5. Verify address / enrollment — wired: [013] Keybus or [902] Corbus; wireless: enroll window and transceiver online.
6. 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 hardwired LCD

• Optional PowerG transceiver SKU requires Pro PowerG firmware level per install manual.
• Partition assignment rules differ from Neo — check Pro programming guide global keypad flags.

Pro hardwired LCD

• Confirm Pro firmware supports PowerG on RF variant before sensor enroll at keypad.

After keypad replacement

Re-assign address, partition visibility, and user PINs per manual — new keypad does not inherit old device programming automatically.

Replacement warning

Keypads are not universal across DSC generations. Confirm bus type, address programming section, and firmware before substituting another model.

Follow PowerSeries Pro HS2LCD(RF)PRO Installation Manual for mounting, wiring, addressing, and enrollment. Summary below — not a substitute for the full manual.

Pre-install checklist

• Match keypad SKU to host panel family (see compatible-peripherals.md).
• Select mounting height and tamper-secure back box per local code.
• Reserve bus power or confirm wireless transceiver capacity on panel.
• Plan partition and global keypad roles for multi-partition installs.

Typical install sequence

1. Mount keypad back box and pull bus or confirm wireless coverage at location.
2. Wire Keybus/Corbus homerun or begin wireless enrollment per manual.
3. Assign keypad address in panel programming ([013] PowerSeries, [902] Neo/Pro, DLS for MAXSYS).
4. Set partition assignment and display options.
5. Test arming, disarming, trouble display, and prox/RF features if equipped.
6. Document address, partition, and installer access for service handoff.

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.
