When is a combination alarm system configured for both burglary and fire purposes?

A combination alarm system is specifically designed to address multiple types of threats, integrating both burglary and fire detection functionalities. The correct answer reflects that this system is recognized as a fire alarm when it includes the capability to detect fire hazards, such as through smoke detectors or heat sensors. This designation is essential because it ensures that the system meets specific safety codes and standards required for fire alarm systems.

Fire alarms are critical components of safety infrastructure, and their integration into a combination system allows for real-time response to both break-ins and fire incidents. This dual functionality enhances the overall security and safety of the premises, providing comprehensive protection for occupants and property. Having smoke detection as part of the system's capabilities is fundamental in registering it officially as a fire alarm system, which is a primary concern for building codes and insurance requirements.

The other options do not sufficiently describe the nature of a combination alarm system configured for both burglary and fire. For example, CCTV integration might enhance security but it does not directly serve the function of fire detection. Similarly, operating without a control panel or simply being equipped with smoke detectors does not inherently categorize a system as a combination system targeted at both types of emergencies.
