Which private alarm signaling system is designed to only notify the occupants within the protected premises of a fire?

The choice that identifies the private alarm signaling system specifically designed to notify only the occupants within the protected premises of a fire is the protected premises fire alarm system. This type of system is intended to alert individuals in the immediate vicinity — such as those inside a building — to the presence of a fire, enabling them to take appropriate action, such as evacuating the premises or activating fire suppression measures.

In contrast, a central station system connects to a monitoring service that alerts emergency services, hence reaching beyond just notifying the occupants. A local alarm system typically refers to alarms that make noise to alert those within hearing range but may not be officially designated as a fire alarm system. The wireless alarm system can vary in purpose and design but may not be specifically limited to notifying only occupants. Therefore, the protected premises fire alarm system is the most precise choice for this particular question, as its primary function is to provide immediate alerts to those within the building, enhancing their safety during a fire emergency.
