System Diagnostics & Troubleshooting
We diagnose the systems that other contractors gave up on.
What we do here
Sometimes the answer to "why is this system tripping?" or "why is this device showing trouble?" requires more than the service tech who installed it. Zion's senior leads take diagnostic-only engagements — paid by the visit, no commitment to do the remediation work after — for clients who need an independent technical opinion or an unstuck inspection.
- Intermittent fire alarm trouble signal diagnosis
- Persistent false alarm root-cause investigation
- Communicator and monitoring path troubleshooting
- Integration debug (alarm-to-HVAC shutdown, alarm-to-elevator recall, alarm-to-access-control release)
- AHJ-issued deficiency root-cause analysis when the cause isn't obvious
- Independent second-opinion review for contested deficiencies
Engagement
Diagnostic visits are billed by the hour (truck + senior tech) with a written summary report and recommendations. You decide whether to use Zion for the remediation or hand the report to your existing contractor. We're transparent about that — the goal is to solve the problem, not to capture the next job.
