Overview
Aritech Reliance XR (NetworX-family) hybrid panels — wired zones with 433 MHz wireless expander options and EN50131-grade commercial features.
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 / UltraSync when a compatible communicator is installed. Installers program zones, user codes, and dialer options with dealer programming tools (varies by Challenger, Reliance, Simon); end users arm/disarm from RAS keypads, keyfobs, or the monitoring 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 — Simon vs Challenger vs Reliance vs Tecom — firmware and modules differ.
- Encryption — TX-E vs hardwired vs Challenger wireless sensors in the field.
- Cell module SKU — Simon Alarm.com LTE vs Challenger/Tecom 4G (AU/NZ SKUs).
- Installer code — required for zone changes; document before service.
- Alarm.com / UltraSync dealer — account status, plan, and remote programming access.

Use official Aritech install PDFs and install guides for exact wiring, enrollment, and firmware — specifications vary by SKU and region.
Troubleshooting
Quick diagnostic flow
- Confirm exact model/SKU on label matches official install guide.
- Clear panel AC and cell troubles before diagnosing wireless devices.
- Read zone trouble — tamper and low battery before "missing."
- Verify TX-E 319.5 MHz vs hardwired vs 433 MHz expander sensor matches panel hardware.
- For cell modules: ICCID, antenna, RSSI, and dealer platform match.
- Power-cycle panel only per dealer policy — document user codes first.
Symptom-based fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| Zone missing | Range or battery | Replace battery; add 433 MHz expander or receiver placement |
| Encryption trouble | Wrong sensor series | Use TX-E on Simon or wired on Challenger DGP |
| Cell fail persists | SKU or activation | Correct LTE module; dealer activates Alarm.com / UltraSync |
| Z-Wave won't include | Prior hub pairing | Exclude from old controller; include near panel |
| Takeover false alarms | Wired loop fault | Check EOL wiring; verify burglary-only zones |
| Cannot arm | Open zone or trouble | Status screen — secure or bypass per policy |
Testing checklist
| Test | How | Pass criteria |
|---|---|---|
| Walk test | Installer walk test mode | Each sensor reports at panel |
| Arm Away | Keypad or Alarm.com / UltraSync | Exit delay; interior sensors active |
| Entry delay | Open entry door | Delay before alarm |
| Cell test | Installer comm test | Success; Alarm.com / UltraSync shows online |
| AC loss | Disconnect panel AC briefly | Battery support; trouble reports |
| Z-Wave device | Toggle from panel/Alarm.com / UltraSync | Device responds |
After replacement
Delete old zone, enroll new hardware, update zone name, run walk test, and notify monitoring dealer if central station records zone numbers.
