Troubleshooting
Enrollment-first approach
- Start with keypad enrollment immediately after panel power-up.
- If first keypad is missed, restart power and repeat within the initial 2-minute window.
- Use [804] for wireless enrollment verification and cleanup.
Zone and I/O conflicts
- Confirm whether onboard I/O is defined as zones 33/34 or as PGMs.
- Resolve duplicate mappings before zone walk tests.
- Test alarm and restore transitions for every enrolled point.
Power budget checks
- Keep AUX draw within 200 mA.
- For external devices, avoid sourcing power from panel AUX if startup current is unknown.
SIA deployment guardrail
For SIA-oriented deployments, verify minimum equipment set is PC9155-433 with WT5500-433 before dispatch.
