What is the minimum time period that a public emergency alarm reporting system must operate its emergency power source for, according to NFPA 72?

The minimum time period that a public emergency alarm reporting system must operate its emergency power source is established to ensure reliability and functionality during critical situations, such as fires or other emergencies. According to NFPA 72, the requirement is set at a minimum of 10 minutes. This is essential as it provides sufficient time for the emergency system to continue functioning, ensuring that alarms can be sounded, communications can be made, and monitoring can occur until the situation is resolved or until backup power can be restored.

The 10-minute requirement serves as a standard to cover the initial response time, which is crucial for safety and effectiveness in emergency management. The specifications are in place to guarantee that these systems are not only compliant but also capable of performing under duress, reinforcing public safety measures.
