Which alarm system is automatically retransmitted or directly transmitted to the fire department?

Which alarm system is automatically retransmitted or directly transmitted to the fire department?

• A. Square, red
• B. Central station
• C. Local alarm
• D. Supervisory system

Answer: (A)

The important idea here is how alarm systems communicate with responders. A central station alarm system is monitored off-site by a remote central station. When an alarm is triggered, the signal is sent to that central station, which automatically notifies the fire department. This automatic relay is what distinguishes it from on-site/local alarms, which only sound at the building, or supervisory systems, which monitor equipment status and do not by themselves dispatch responders. The option described as a symbol or device like “square, red” isn’t a recognized system type for automatic dispatch.
