Signal given by a fire detection and alarm system when there is a fire condition detected.

• A. Supervisory Signal
• B. Alarm Signal
• C. Trouble Signal
• D. Fire Alarm Indicator

Answer: (B)

When a fire condition is detected, the fire detection and alarm system issues the alarm signal. This is the active alert that triggers occupants' alarms (audible and visual) and can initiate automatic notifications or evacuations. Other terms describe different statuses: a supervisory signal is used for monitored equipment like valves or pumps that must stay under supervision; a trouble signal signals faults or problems within the system; a fire alarm indicator is simply a display showing that an alarm is active, not the signal itself. So the alarm signal best fits the action taken by the system in response to detecting fire.
