Which components are considered basic parts of a fire alarm system?

The basic parts of a fire alarm system encompass all essential components that work together to detect fire, notify occupants, and facilitate a response. The control panel serves as the system's brain, managing the operation of all components and processing signals from initiating devices, such as smoke and heat detectors. Initiating devices are critical as they detect fire conditions and trigger the system. Notification devices, including alarms and strobe lights, are vital for alerting occupants of a fire, ensuring they have sufficient time to evacuate. Lastly, a power supply is required to maintain the functionality of the entire system, especially in the event of a power failure.

This integration shows why this option includes all critical elements necessary for a fire alarm system's operation, making it comprehensive. Other choices may omit key components, making them incomplete for the required functionalities of a standard fire alarm system. For instance, focusing only on notification devices and power supply neglects the essential role of the control panel and initiating devices in overall fire detection and response mechanisms.
