What CAD Actually Does — and What It Doesn't

How a 911 call becomes an incident, how units are recommended and dispatched, how apparatus status and location are tracked, and why so many other department systems depend on CAD.

The short version

Computer-Aided Dispatch is one of the central systems in a fire department's technology environment. It receives incident information from the emergency communications center, identifies resources, supports unit recommendation and dispatch, records unit status and timestamps, and exchanges information with other systems. CAD does not automatically make every connected system interoperable. How data enters and leaves the CAD depends heavily on system architecture, interfaces, standards, configuration, and vendor capabilities.

Unified Computer-Aided Dispatch Functional Requirements

The federal statement of what a CAD system should be able to do, written for public agencies rather than by a vendor.

Why it matters

Gives you a neutral yardstick to hold a CAD proposal against, instead of comparing one vendor's feature list to another's.

Questions to ask your vendor

  1. What systems currently receive data from our CAD?
  2. What systems send data into CAD?
  3. Which connections are standard interfaces and which are custom?
  4. Who owns and maintains each interface?
  5. What happens to those connections if we change CAD vendors?
  6. Can CAD data be accessed through a documented API?
  7. Can we export our historical CAD data in a usable format?
  8. Where do our response-time timestamps actually originate?
  9. How does unit status differ from unit location in our system?
  10. Does AVL affect unit recommendation here, or is it station-based?
