Which of the following statements about fire safety is true in regard to alarm systems?

Alarm systems are designed to be an integral part of fire safety, and one crucial aspect of ensuring their effectiveness is regular maintenance. Regular maintenance is important because it ensures that all components of the alarm system function correctly when needed. This includes checking the sensors, batteries, and signaling devices to ensure they respond effectively to potential fire hazards. Without proper maintenance, the reliability of the alarm system can deteriorate over time, leading to increased risks during emergencies.

The other statements present misunderstandings about the roles and capabilities of alarm systems. For instance, alarm systems do not suppress fires; rather, they are intended to detect them and alert individuals to take necessary action. Additionally, while many alarm systems detect smoke, they are often designed to sense other elements such as heat, ensuring a broader range of detection. Lastly, the functionality of most alarm systems depends on an electrical power source, which means they cannot work effectively without electricity unless they have backup power options.
