Two-way, in-building emergency communications systems are also called?

• A. Intercom systems
• B. Public address system
• C. Firefighters' telephones
• D. Emergency exit alarms

Answer: (C)

Two-way, in-building emergency communications used during fire events are called firefighters’ telephones. This term refers to a dedicated, reliable voice link between the Fire Command Center and the various parts of a building, often spanning different floors, so firefighters can coordinate actions, relay information, and request support quickly during an incident. The system runs on a dedicated circuit to stay functional even if other building communications are compromised, which is crucial in an emergency. Intercom systems exist for general communication between occupants and staff, but they aren’t designed to meet the reliability and direct fire department coordination needs of an emergency. Public address systems are mainly for making announcements to occupants and aren’t built for the two-way, firefighter-focused communication required during a fire. Emergency exit alarms are signals that indicate doors are being opened for egress and do not provide two-way communication.
