What is a common use of audio notification devices in a master-coded alarm system?

In a master-coded alarm system, audio notification devices serve multiple purposes beyond just emergency alerts. They can be used for a range of announcements, including but not limited to school bells, instructional messages, and general notifications. This versatility is essential in environments such as schools or large facilities where different types of announcements are needed throughout the day.

This broad capability allows for efficient communication and enhances safety by providing timely and diverse alerts based on varying needs. By utilizing audio notification devices for various announcements, organizations can effectively manage and relay important information across different situations, ensuring that all occupants are informed and responding appropriately.
