What is the main purpose of fire alarm systems?

The primary purpose of fire alarm systems is to detect and alert occupants to fires. These systems are designed to identify the presence of smoke, heat, or flames in an environment, allowing for an early warning that can save lives and minimize property damage. When a fire is detected, the alarm system activates audible and visual alerts, which notify occupants to evacuate the building in a timely manner, thus enabling emergency services to respond quickly.

While other options may involve aspects of building design and function, they do not pertain to the essential role of a fire alarm system. Enhancing aesthetics, providing entertainment, or automating maintenance are not objectives of fire alarm systems; their sole focus is safety and protection against fire hazards.
