The alarm system must re-initiate its audible signal in response to what condition?

The alarm system is designed to ensure continuous safety and vigilance regarding the status of medical gas systems. When a specific alarm condition is detected, the system must re-initiate its audible signal to alert personnel about the ongoing issue that requires attention. This is crucial because an active alarm indicates a potentially hazardous situation, prompting immediate action or intervention.

In the context of a medical gas system, the alarm may signify issues such as low pressure, high pressure, leaks, or other dangerous conditions that can affect patient care. The audible signal serves as a crucial mechanism to make sure that any changes in the system's state are communicated effectively to personnel who may not be in the immediate vicinity of visual alerts.

Other conditions mentioned, such as manual disarm, power failure, and signal testing, do play important roles in the functioning of the alarm system, but they do not mandate the re-initiation of an audible signal as an active response to an existing alarm condition. For instance, manual disarming could silence the alarms intentionally when they are no longer needed while a power failure might switch the system to a standby mode rather than alerting for another emergency condition. Signal testing is typically a planned procedure intended to ensure functionality, rather than a response to an alarming event.
