What describes a master-coded alarm system?

A master-coded alarm system provides a way to manage notifications for various situations, which can include fire alarms as well as other types of alerts, such as security breaches, temperature changes, or other emergencies. This system is designed to operate multiple notifications concurrently and efficiently, ensuring that appropriate responses can be triggered for different types of incidents.

The key reason for its identification in the context relates to its multifunctionality, allowing it to serve broader purposes than just fire detection. This capability enhances the overall safety and security management of a building, making it suitable for environments where various risks need to be monitored simultaneously.

In contrast, while option A may imply it is a modern installation, it does not specifically address the unique feature of combining multiple notification types. Option C, while mentioning important operational details, does not encompass the diverse range of alerts handled by the system. Option D incorrectly associates the master-coded alarm system with small, older buildings, which does not reflect the adaptability and application of this system in more diverse, modern contexts.
