Public Address (PA) systems are essential for general communication in various settings, including public spaces, businesses, and institutions. These systems allow for the broadcast of announcements, information, and instructions to a large audience. While Public Address systems primarily serve non-emergency communication purposes, they are still crucial for disseminating everyday messages, making announcements. In contrast, Voice Alarm systems (VAS), which are often integrated with Public Address systems, are specifically designed for emergency situations and play a critical role in guiding people to safety during fires, evacuations, or other crises. Both PA and VA systems contribute to effective communication and safety.
