Which condition is NOT alarmed in sources with standby headers?

The condition of low discharge temperature is not typically alarmed in sources with standby headers because it is often a normal operating condition that does not immediately indicate a problem. Standby headers are designed to ensure the continuous supply of medical gases, and while monitoring is important, certain parameters, like low discharge temperature, may be acceptable within a certain range or not lead to an alarmed state unless they fall below a critical threshold.

In medical gas systems, conditions like high dew point or low reserve levels are crucial to monitor because they can have immediate implications for safety and equipment performance. An elevated dew point can indicate moisture in the gas line, which can lead to contamination, while reserve conditions such as "reserve in use" and "reserve low" help ensure that there is always an adequate supply for medical needs. By focusing on these key parameters, the system can maintain optimal functionality and safety, whereas low discharge temperature is less indicative of immediate issues.
