A Building Occupant Warning System (BOWS) is designed to assist people in safely evacuating during emergencies. It delivers critical alerts through strategically placed speakers, ensuring clear communication in high-risk situations. This system can be activated manually or triggered automatically when a threat is detected.
The Emergency Warning System broadcasts evacuation instructions, public announcements, or emergency alerts to guide occupants to safety. Its reliable design ensures messages are heard throughout the building, reducing confusion and improving response times.
Beyond emergencies, a Building Occupant Warning System (BOWS) can also be used for general announcements or background music, enhancing everyday communication within the building.
