A conventional fire alarm system is a type of fire detection and notification system commonly used in smaller buildings and facilities. It consists of a network of interconnected fire detectors, manual call points, and alarm sounders that are divided into separate zones.

An addressable fire alarm system is an advanced type of fire detection and notification system commonly used in larger buildings or facilities that require more precise identification of fire events. Unlike conventional fire alarm systems, addressable systems allow individual devices to be uniquely identified by their specific address.
