Final answer:
When a fire service or EMS call is received, the telecommunicator alerts the station with adequate initial information and continues to provide supplemental details to the responders enroute.
Step-by-step explanation:
Upon receipt of a fire service or EMS call, the telecommunicator will alert the station or department and provide an adequate amount of information concerning the call with initial dispatch and then follow up by providing supplemental information to response units once they are enroute. This includes details such as the nature and severity of the incident, exact location, and any other critical information that may affect the emergency response. Over time, as more information becomes available or the situation evolves, the telecommunicator continues to communicate vital updates to ensure the safety and effectiveness of the responding units.
