Which alarms activate when the reserve supply takes over in a cylinder-supplied system?

In a cylinder-supplied medical gas system, when the reserve supply takes over, it is essential for the facility's safety and operational integrity to be alerted to this change in supply. Master alarms are specifically designed for this purpose, serving as a primary notification mechanism for healthcare staff to indicate that the transition from a main supply to a reserve supply has occurred.

When the reserve supply activates, it signals that the main source has potentially been depleted or is no longer available. The master alarm provides an immediate and clear indication to staff that they need to check on the gas supply status and ensure there is adequate supply for the ongoing medical needs of patients. This is particularly critical in a healthcare setting where a constant supply of medical gases, such as oxygen or nitrous oxide, is vital for treatment.

Visual alarms or audio alarms might also be present in the system, but they are typically considered secondary notifications. Backup alarms might not specifically inform staff of the transition to reserve supply. The primary design and function of master alarms are to centralize and draw immediate attention to significant changes in medical gas supply systems, ensuring that safety practices are maintained.
