What is required of the alarm system if another alarm condition occurs while the audible alarm is manually silenced?

In medical gas systems, when an audible alarm is manually silenced, the system must still be capable of notifying personnel of any new alarm conditions that arise. The requirement for re-initiating the audible signal ensures that critical information about potential hazards is communicated effectively, even if vigilance has been temporarily reduced by the silencing of previous alerts.

This mechanism serves an important safety function, as it guarantees that new and potentially life-threatening conditions are not overlooked, thereby allowing for a timely response from staff. The audible alarms are designed to prioritize alerts based on the urgency and significance of the situation, which is crucial in a medical setting where gas system integrity is vital for patient safety.

The other options, while they might seem plausible in terms of alerting personnel, do not fulfill the requirement for maintaining continuous warning capabilities during a silenced alarm condition. Visual alerts alone may not attract immediate attention in urgent scenarios, and reliance on manual checks could lead to delays in response, compromising safety. Thus, the necessity for re-initiating the audible signal is critical for maintaining an effective alarm system.
