The master alarm system shall activate when the pressure in the main supply lines increase or decrease by how much percent?

The master alarm system is designed to safeguard the integrity and reliability of medical gas systems by monitoring various parameters, including pressure levels in the main supply lines. A pressure fluctuation of 20% is significant enough to indicate a potential issue, such as a failure in the supply system or a malfunction in the machinery that could compromise patient safety.

Activating the alarm at this threshold allows for timely intervention to address any irregularities that could affect the delivery of medical gases, ensuring that medical facilities can respond promptly to potential hazards. The selection of a 20% deviation reflects a balance between being sensitive enough to detect real problems while avoiding unnecessary alarms that could lead to alarm fatigue among the staff.

Knowing the correct threshold for pressure activation is crucial for maintaining operational safety and adherence to national standards for medical gas systems.
