How is an alarm indicated locally by a fire alarm panel?

• A. By activating audible notification devices and strobes, and displaying alarm indicators on the panel.
• B. By triggering only the building's automatic doors.
• C. By flashing the panel's lights without sound.
• D. By sending a notification email to occupants.

Answer: (B)

Locally, a fire alarm panel signals an alarm by sounding audible notification devices throughout the building and activating visual strobes, while also lighting up alarm indicators on the panel to show exactly which zones are affected. This combination provides immediate, on-site awareness for occupants and responders—the sound catches attention and the lights provide a clear, persistent cue, with the panel display guiding responders to the source or area in alarm.

Other options miss part of the local signaling: flashing the panel lights without any sound doesn’t reliably alert people in the area, and triggering automatic doors isn’t how the alarm indication is communicated. Sending a notification email is a remote alert, not a local one.
