Free PSD Computer-Aided Dispatch (CAD) Systems Operations Questions and Answers 1 — Questions and Answers
Question 1: What is the primary function of a Computer-Aided Dispatch (CAD) system in a public safety communications center?
- To automatically route 9-1-1 calls to the correct dispatcher.
- To create, manage, and track incidents and the deployment of resources. (Correct answer)
- To record all incoming and outgoing telephone and radio communications.
- To provide field units with turn-by-turn navigation to an incident.
Correct answer: To create, manage, and track incidents and the deployment of resources.
A CAD system is the central tool used by dispatchers to manage calls for service. It facilitates the creation of incident records, prioritization of calls, dispatching of units, and tracking of responder activities from the initial call to its conclusion.
Question 2: In a CAD system, what does the acronym 'AVL' stand for and what is its purpose?
- Automated Voice Logging; it records radio transmissions.
- All-Vehicle Locator; it finds any vehicle by its license plate.
- Automatic Vehicle Location; it tracks the geographic position of field units. (Correct answer)
- Available Unit List; it shows which units are not on a call.
Correct answer: Automatic Vehicle Location; it tracks the geographic position of field units.
Automatic Vehicle Location (AVL) uses GPS technology to track the real-time location of public safety vehicles. This information is displayed on the dispatcher's map, allowing them to dispatch the closest available unit to an incident, which improves response times and enhances officer safety.
Question 3: How does a typical CAD system assist a dispatcher in prioritizing calls for service?
- By automatically assigning the highest priority to the first call received.
- By allowing field units to select their own calls from a list.
- By using a pre-defined coding system that ranks incidents by severity. (Correct answer)
- By randomly assigning priorities to ensure all calls are handled fairly.
Correct answer: By using a pre-defined coding system that ranks incidents by severity.
CAD systems use a priority system, often numerical or color-coded, based on the nature of the call entered by the dispatcher. For example, a report of a robbery in progress would be assigned a higher priority than a noise complaint, ensuring that life-threatening emergencies are handled first.
Question 4: What is the main purpose of the 'unit status monitor' feature in a CAD system?
- To track the maintenance schedule for each vehicle.
- To display the real-time activity status and location of all field units. (Correct answer)
- To allow units to send private messages to each other.
- To monitor the fuel levels and engine diagnostics of the fleet.
Correct answer: To display the real-time activity status and location of all field units.
The unit status monitor is a critical component for situational awareness. It provides the dispatcher with a real-time, at-a-glance view of the status of every on-duty unit (e.g., In Service, En Route, On Scene, In Pursuit), allowing for effective resource management and enhanced responder safety.
Question 5: When creating a new call for service (CFS) record in CAD, which of the following pieces of information is considered the most critical to obtain first?
- The caller's full name and date of birth.
- A detailed description of the suspect.
- The exact location of the incident. (Correct answer)
- The caller's relationship to the incident.
Correct answer: The exact location of the incident.
While all information is important, the location of the incident is paramount. If the call is disconnected for any reason, having the location allows the dispatcher to send help. All other details, such as caller name or the specifics of the event, are secondary to knowing where to send responders.
Question 6: What is a 'geofile' or 'geobase' within the context of a CAD system?
- A file containing the personnel records of all dispatchers.
- A database of all streets, addresses, and jurisdictional boundaries. (Correct answer)
- A log of all geological or weather-related alerts.
- A list of past incidents that occurred at a specific location.
Correct answer: A database of all streets, addresses, and jurisdictional boundaries.
A geofile is the master database of streets, addresses, landmarks, and response districts within the agency's jurisdiction. The CAD system uses the geofile to validate addresses entered by the dispatcher, recommend the appropriate response units, and provide mapping data.
Question 7: Why is it crucial for a dispatcher to use standardized terminology and ten-codes when entering information into the CAD narrative?
- To save keystrokes and enter calls faster.
- To ensure clarity, consistency, and reduce the risk of miscommunication. (Correct answer)
- To make the CAD record more difficult for the public to understand if released.
- To meet the minimum requirements of the software vendor.
Correct answer: To ensure clarity, consistency, and reduce the risk of miscommunication.
Using standardized codes and clear, concise language ensures that information is universally understood by all personnel, both in the communications center and in the field. This practice reduces the chance of misinterpretation, which is critical for responder safety and operational efficiency, and it also aids in later data analysis.
