Which term refers to a digital alarm communicator in alarm systems?

• A. DACT/DACR
• B. McCulloh Copper wires
• C. Alarm horn
• D. Smoke detector

Answer: (A)

The term refers to the device responsible for sending alarm data from the panel to the monitoring center in a digital format. This is the DACT (Digital Alarm Critical Transmitter) and its counterpart the DACR (Digital Alarm Communicator Receiver). In a monitored alarm system, the DACT acts as the transmitter that converts events into digital signals and uses a communication path—such as a phone line, cellular network, or IP—to reach the central station. The DACR is what receives those signals at the monitoring facility. This concept is distinct from physical cabling, audible output devices, or sensors: copper wire is just wiring, an alarm horn is an audible alert, and a smoke detector is a sensor.
