Overview
The Qolsys IQ Panel 4 is an all-in-one touchscreen security hub with built-in PowerG radio, Z-Wave Plus automation, Wi-Fi/cellular paths to Alarm.com, and a modern Android-based user interface.
The panel is the brain of the intrusion system: it supervises wired and wireless zones, drives bell/siren outputs, manages automation on supported models, and reports to Alarm.com when a compatible communicator is installed. Installers program zones, user codes, and dialer options with installer menu / pairing wizard (varies by IQ Panel 4, 5, Hub); end users arm/disarm from IQ Remote, keyfobs, or Alarm.com app.

What This Panel Does Well
Coordinates intrusion zones, automation, user codes, and central station reporting when cell and monitoring are configured.
Before You Service or Replace One
- Exact panel model — IQ Panel 4 vs IQ5 vs IQ Pro vs IQ Hub — firmware and modules differ.
- Encryption — PowerG vs legacy card vs hardwire module sensors in the field.
- Cell module SKU — Built-in cellular vs Wi-Fi path per panel SKU and Alarm.com plan.
- Installer code — required for zone changes; document before service.
- Alarm.com dealer — account status, plan, and remote programming access.
Official Sources
Use official Qolsys install PDFs and install guides for exact wiring, enrollment, and firmware — specifications vary by SKU and region.
Error Codes
IQ Panel systems report faults on the panel and keypad status screens, zone list, and Alarm.com (when interactive service is active) — not as a single universal numeric code list across all models.
How to read status
- Open panel status or installer menu → zones / troubles.
- Note zone number, trouble type (open, tamper, low battery, missing, cell fail).
- Cross-check Alarm.com device list if the account is interactive.
- For cell issues, run installer communication test before replacing sensors.
Common trouble indicators
| Panel / keypad display | Meaning | First checks |
|---|---|---|
| COMM FAIL / Cell failure | Cellular path down | Antenna, SIM, carrier, module SKU vs account |
| Sensor fault / zone open | Zone not secure or missing | Battery, gap, tamper, re-learn sensor |
| AC loss | Mains power removed | Transformer, outlet, power supply SKU |
| Low battery (panel) | Backup battery weak | Charge time; replace panel battery if aged |
| Z-Wave fault | Automation device offline | Exclude/re-include; verify within mesh range |
| RF fault | PowerG vs IQ Card frequency mismatch | Match sensor family — PowerG S-Line on IQ Panel; legacy on IQ Card; hardwire via IQ Hardwire 16-F |
