Troubleshooting

Wiring and mounting checks

  • Secure DC+/DC− terminations — loose screws cause intermittent AUX trouble.
  • Route Class 2 wiring separately from AC mains and bell circuits.
  • Confirm panel-side voltage ≥ manual minimum with all keypads powered.

Load troubleshooting

  • Add modules one at a time — if trouble appears after specific module, that device exceeds budget.
  • HS3032/3128/3248 share Corbus/AUX budget — reserve 100 mA for Corbus before accessories.

Class 2 external mount

When adapter is outside panel enclosure, use Class 2 wiring and follow AHJ inspection rules.
