What is the term for buildings equipped with fire alarm systems?

The correct term for buildings equipped with fire alarm systems is "Protected premises." This term is used in the context of fire protection and emergency management to refer specifically to structures that have installed systems designed to detect fires early and alert occupants, as well as emergency services if necessary. The presence of fire alarm systems in these buildings provides a level of safety and assurance that helps to minimize the risk of fire-related incidents and improve response times when alarms are triggered.

Understanding this terminology is crucial for firefighters and safety personnel, as it helps them identify which buildings have the necessary systems in place to facilitate effective fire response strategies. Other options such as "Designated structures," "Emergency facilities," and "Controlled environments" do not specifically denote buildings with fire alarm systems, which is why they are not the correct choice. Instead, "Protected premises" captures the essential concept of safety measures linked to fire alarms and emergency preparedness.
