What is the operation duration required for emergency/voice alarm communication during an emergency?

The operation duration required for emergency/voice alarm communication during an emergency is critical to ensure effective communication and response. The correct duration of two hours is established to maintain a reliable means of communication during a potential emergency situation, reflecting the need for sustained operation in the event of an emergency until help arrives or the situation is stabilized. This timeframe allows emergency personnel to relay crucial information, coordinate actions, and provide updates to affected individuals.

Choosing two hours as the standard aligns with operational protocols in emergency management, balancing the need for reliability while also considering the limitations of equipment and battery life. In contrast, shorter durations may not provide sufficient time for the scenario to evolve, while longer durations might lead to unnecessary resource usage without providing additional benefit.
