What type of alarm panel is permitted for category 2 warning systems?

In the context of medical gas systems, a category 2 warning system is designed to indicate a malfunction in the medical gas delivery system that requires immediate attention but does not pose an imminent danger to patient health or safety. The correct answer pertains to the specifications of alarm systems suitable for these warning categories.

A single alarm panel is permitted for category 2 warning systems because it effectively serves its purpose and meets regulations without the complexity or redundancy required for more critical alarms. Single alarm panels are simpler in design and can provide necessary alerts directly at the source of the problem, making them appropriate for situations where immediate action is required but where the implications of an alarm are less severe compared to more critical categories.

In comparison, options such as dual, local, and master alarm panels generally involve more complex configurations intended for higher category warning systems or specific operational needs. Dual panels often serve systems needing redundancy or additional layers of alerting not essential for category 2. Local panels provide alerts at specific locations, but may lack the broader monitoring capabilities needed for multiple areas, not aligning with category 2 requirements. Master alarm panels, on the other hand, are designed for comprehensive monitoring of all systems and would be excessive for the scenarios addressed by a category 2 warning system.
