The system includes a terminal for what type of emergency communication with the fire department?

• A. Two-way fire department telephone
• B. One-way loudspeaker
• C. Data modem link
• D. Email alert

Answer: (A)

Emergency communications with the fire department require a direct, bidirectional voice path. The two-way fire department telephone provides real-time, live communication between the protected site and the fire department, which is essential for dispatch coordination and information exchange during an emergency. The other options don’t offer a live voice channel: a one-way loudspeaker is just for announcements, a data modem link carries data but not real-time conversation, and an email alert isn’t immediate or reliable for urgent fire department contact.
