What is characteristic of a local fire alarm system?

A local fire alarm system is designed primarily to provide audible and visual alerts within a specific building or area to notify occupants of a fire or emergency situation. This system is crucial for ensuring that everyone inside the building is aware of the danger and can respond appropriately by evacuating the premises or taking other necessary actions.

The characteristic of this system emphasizes its limited scope; while it effectively communicates the alarm to those within the building, it does not reach beyond its immediate vicinity to alert external parties such as the fire department or communicate with other buildings. Therefore, the local nature of the alarm is a key attribute, focusing solely on internal alerts without automatic notification to outside emergency services or interconnectivity with multiple structures.
