Which of the following is NOT a classification of carbon monoxide detection equipment and systems?

• A. Integrated systems
• B. Standalone systems
• C. Networked systems
• D. Central monitoring

Answer: (A)

Carbon monoxide detection equipment is categorized by how it operates and connects within a life-safety setup. Standalone detectors work on their own, with no connection to a fire alarm control panel. Networked detectors are linked together and typically feed into a fire alarm control panel to coordinate alarms throughout the building. Central monitoring involves those detectors or systems sending signals to a remote monitoring station for response. Integrated systems describe CO sensing that is combined with other building or fire alarm systems, rather than a standalone category of its own. Because it’s a configuration description rather than a distinct installation/communication class, integrated systems isn’t a separate classification of CO detection equipment and systems.
