Which statement indicates no unit is available to respond?

• A. Check criminal history
• B. No unit available
• C. Maintance (sensor or other)
• D. Sensor hit

Answer: (B)

Understanding how responders communicate availability is key. The phrase that directly indicates there isn’t any unit ready to respond is the one that states no unit is available. This signals that all units are tied up or out of service, so no dispatch can be sent at that moment and the caller or supervisor needs to be informed and options explored (like waiting, re-prioritizing, or escalating to a supervisor).

The other options point to different actions or events: checking criminal history is a task to perform on a case, maintenance signals a equipment issue that could affect response, and a sensor hit is an event notification. None of these convey the current status of unit availability.
