A ________ is a system component that accepts and displays signals from a DACT sent over the public switched telephone network?

• A. DARR
• B. DACR
• C. DART
• D. CPU

Answer: (B)

The main idea is that signals from a Digital Alarm Communicator Transmitter (DACT) traveling over the public switched telephone network are received by a device specifically designed to handle those incoming digital signals at the central station. That device is the Digital Alarm Communications Receiver (DACR). It takes the encoded data from the DACT, decodes it, and presents the alarm information to the alarm operator through the monitoring display or annunciation system, often logging or routing the event for responders. Other options don’t fit because they don’t serve as the central-station receiver and display for PSTN-delivered DACT signals—the Digital Alarm Receiving Relay is more about relay outputs, a Digital Alarm Receiving Terminal is not the standard term for the central receiver, and a CPU is a general processor rather than the specialized PSTN alarm receiver.
