Which indicator is associated with the Flag Drop condition?

• A. DS1 Power Indicator
• B. DS2 Flag Drop Indicator
• C. DS3 Airflow Alarm Indicator
• D. LS1 Local Audible Alarm

Answer: (B)

Flag Drop is signaled by the indicator labeled DS2 Flag Drop Indicator. On panels with multiple diagnostic indicators, each DS item points to a specific condition, and the one explicitly labeled for Flag Drop is the DS2 indicator. When Flag Drop occurs, DS2 will light or activate to alert you, guiding you to the exact issue. The other indicators serve different purposes—for example, DS1 shows power status, DS3 relates to airflow conditions, and LS1 is a local audible alarm for general alarms—so they don’t indicate Flag Drop.
