Besides the colors, how can an alarm monitor identify the alarm?

• A. There is no other cue.
• B. The panel displays a texture pattern.
• C. Alarm codes indicate user identity.
• D. Alarm codes also have interpreting sounds.

Answer: (D)

Alarms are identified by more than color alone; using both visual and auditory cues helps the operator know exactly which alarm is active. Alarm codes are paired with specific sounds or spoken prompts that map to that code, so hearing the sound tells you which alarm it is even if the color cue isn’t clear. This audio signaling speeds recognition in busy or low-visibility conditions and reduces confusion by providing immediate, distinguishable identification of the event. The other ideas either imply there’s no extra cue, rely on an unlikely texture display, or focus on who triggered the alarm rather than which alarm it is, whereas the sounds tied to the codes give a direct, reliable means of identification.
