Which of the following is NOT a classification of a fire alarm system?

The classification of fire alarm systems is primarily categorized into three main types: automatic, manual, and a combination of the two. An automatic fire alarm system triggers alerts without human intervention when it detects fire conditions through smoke, heat, or other indicators. A manual fire alarm system requires a person to activate the alarm, usually by pulling a manual pull station. It is essential to recognize that the term "integrated" does not represent an official classification of fire alarm systems; instead, it often describes systems that combine fire alarms with other building safety systems, such as security or emergency communication systems.

The classification of fire alarm systems focuses specifically on how they operate — whether automatically triggered or manually activated. Therefore, identifying integrated as a classification would be inaccurate, as it does not fall within the standard categorizations used in fire alarm technology. Understanding these classifications is crucial for ensuring safety protocols are followed correctly in the event of a fire, as different systems have distinct roles in emergency response.
