What type of warning system provides a continuous visible and audible vigilant watch on category 1 and 2 piping systems?

The type of warning system that provides a continuous visible and audible vigilant watch on category 1 and 2 piping systems is the area alarm. This system is specifically designed to monitor medical gas systems and alert personnel to any issues or malfunctions that may arise.

Area alarms are crucial components in the safe operation of medical gas systems, as they provide immediate notifications to staff in the event of a fault, ensuring that any potential hazards are quickly addressed. Their continuous monitoring capability helps maintain compliance with safety standards outlined in NFPA 99, ensuring patient safety and the integrity of medical gas delivery in healthcare facilities.

This distinct functionality sets area alarms apart from other types of systems. For example, while an emergency alert system may focus on broader emergency notifications, it does not specifically monitor medical gas systems. Similarly, a patient alert system is typically designed for immediate patient needs rather than continuous monitoring of gas piping systems. A monitoring alarm system could refer to various monitoring functions but does not specifically emphasize the vigilant monitoring aspect tied to category 1 and 2 piping systems.
