Annunciation to the fire command center shall be:

• A. Audible only
• B. Audible and visible
• C. Visible only
• D. None

Answer: (B)

Annunciation at the fire command center should be audible and visible. The combination ensures that alarms are noticed quickly and that responders can immediately identify where the alarm originated. The audible signal draws attention across the building, while the visual indication (such as panel lights or a zone display) shows exactly which zone or device activated. Relying on sound alone can miss alarms in noisy environments or for those with hearing impairments, and relying on visuals alone can be missed in darkness or when attention isn’t on the panel. Providing both guarantees faster recognition, clearer communication, and a quicker, coordinated response.
