What does Fault Detection & Diagnostics do?

For building integrators, every truck roll has a cost. A technician sent out for a minor issue is lost time. A technician sent out for no real issue is worse. The hard part has never been a lack of data. Building systems generate plenty of it. The hard part is using that data to validate performance and find the real problem first.

That’s exactly where Fault Detection & Diagnostics in KODE OS earns its place in an integrator’s workflow.

FDD continuously monitors equipment and point data across the building. From there, it turns that constant stream into clear, prioritized, actionable signals. As a result, integrators can validate system performance remotely and find the issue from the platform. Ultimately, you understand the likely root cause before sending anyone on location.

That changes how integrators operate. Your team implements some fixes remotely, with no dispatch at all. And when a technician is needed, they roll out already knowing what’s wrong. They know why it happened and what to bring before they arrive. This cuts wasted trips and saves labor hours. You resolve issues faster and keep a transparent record of what your team found and did.

How can I use it?

The FDD platform is designed around how teams actriage and resolve building issues, moving from detection to diagnosis to resolution without leaving the platform. Here’s how you can use it:

  • See every active event in one place: All active faults across the building appear in a single view, so nothing gets lost across disconnected systems.
  • Filter by priority level: Narrow the list down to warnings or other priority levels instantly, so the most important issues rise to the top.
  • Understand what triggered each fault: Then open any fault to see a trend showing exactly which point value set it off.
  • Act on recommended solutions: Next, review possible solutions and push a work order directly from the platform into your third-party work order system.
  • Use AI to diagnose faster: Get a generative AI analysis of the fault, including likely root causes and recommended next steps.
  • Route faults to the right people: Also, assign faults to team members who are notified by text, email, or phone call, and have them acknowledge them to keep triage organized.
  • Learn from history: Run analytics across months of fault data to spot recurring issues and patterns across the building.

Ultimately, the result is a faster, more consistent response process, from the moment a fault appears to the moment it’s resolved.

Real-time visibility into every fault

First, the FDD platform shows you every active event in your building, centralized in one place.

Teams get an immediate, real-time picture of what’s happening across their equipment. No checking multiple systems. No waiting for a complaint to surface the problem.

From there, the priority filter at the top lets you focus. Select a priority level, such as all warnings, and the list automatically filters down to just those events. That makes it easy to separate the issues that need attention now from the noise, and to work through faults in a deliberate, prioritized order.

For integrators managing complex buildings, that single prioritized view is what keeps a flood of alarms from becoming unmanageable.

Trends that show exactly what triggered the fault

Then, when you click into a fault, KODE OS shows a trend of the exact point value that triggered it.

This matters because diagnosis usually starts with a question: what actually went wrong? Instead of digging through raw point histories to reconstruct the event, the trend puts the triggering data front and center.

That context shortens the path from ‘something is wrong’ to ‘here’s what’s wrong and why.’ That’s exactly where most troubleshooting time is lost.

Built-in tools to diagnose, document, and dispatch

Alongside each fault, KODE OS gives teams everything they need to move from diagnosis to action without switching platforms:

  • Possible solutions suggest where to start.
  • Work order push sends a work order directly from KODE OS into your third-party system. Resolution happens in the tools your team already uses.
  • Reference devices provide related equipment context.
  • Comments and activity logs capture every step the team investigates and completes, creating a clear record for the next person who touches the fault.

Ultimately, this keeps diagnosis, documentation, and dispatch in one continuous workflow, instead of scattered across email threads, spreadsheets, and separate systems.

AI suggestions for faster root-cause analysis

Each fault also includes an AI Suggestion tab.

Here, KODE OS’s generative AI analyzes the fault and returns a clear breakdown. You get a statement of the problem, the likely root causes, and recommended next steps.

For example, for less experienced technicians, this provides expert-level guidance on the spot. Meanwhile, for seasoned operators, it’s a fast second opinion that confirms a hunch or surfaces a cause they hadn’t considered. Either way, it compresses the time between detecting a fault and knowing how to fix it.

Assignees and acknowledgments that keep triage organized

Next, the Assignees tab is where FDD becomes a team workflow.

You can add assignees to a fault and choose how they’re notified, by text message, email, or phone call, based on the fault. When an assignee acknowledges a fault, the team sees a clear line between what’s handled and what still needs attention.

Still, that acknowledgment step is deceptively important. It’s what lets a team triage at scale, ensuring nothing slips through the cracks and no two people unknowingly chase the same issue.

Historical analytics that turn faults into insight

Finally, the Historical tab keeps a record of your faults over time and lets you run analytics across multiple months of issues.

Instead of treating each fault as a one-off, teams can see patterns. Think equipment that fails repeatedly, recurring seasonal issues, or systems that quietly generate more faults than they should. Those actionable analytics turn day-to-day firefighting into longer-term operational improvement.

Why this matters

Most tools either detect faults or help manage work orders. FDD in KODE OS connects the entire response loop, from detection to diagnosis to dispatch to long-term analysis, in one platform.

As a result, that difference changes how teams operate:

  • No waiting for complaints to surface problems.
  • No reconstructing events from raw point data.
  • No faults lost between disconnected systems.
  • No starting troubleshooting from scratch every time.

For building integrators, FDD provides the visibility and tools to catch issues early, respond fast, and keep systems running effectively. The workflow stays consistent enough to scale across a portfolio, building after building.

See it in action

From real-time fault visibility to AI-assisted diagnosis and historical analytics, this is what staying ahead of building issues looks like in KODE OS.

In this edition of Inside the Dashboard, Charlie Cochrane walks through the full workflow. Teams detect faults, diagnose root causes, route issues to the right people, and learn from months of fault history, all from one platform
