What does YELLOW alarm color signify?

• A. Alarm point is in use.
• B. Alarm point is secure.
• C. Alarm point is pending.
• D. Alarm point is accessed or is in use.

Answer: (D)

In alarm monitoring, color codes quickly convey status. Yellow shows that the alarm point is being accessed or is currently in use. This captures both situations: someone actively at the point and the point undergoing use as part of a process. It informs operators to expect activity at that location and to verify that the access or use is authorized. It’s different from secure (which implies no active interaction, often represented by green) and from pending (which suggests awaiting action). The nuance of “accessed or in use” is why yellow is the best match for indicating active interaction with the alarm point.
