What two actions must a digital alarm communicator transmitter perform?

• A. Transmit signals and receive acknowledgement
• B. Transmit signals only
• C. Receive acknowledgement only
• D. Log events

Answer: (A)

A digital alarm communicator transmitter must do two things: send the alarm signals and receive an acknowledgement from the monitoring station. The transmission sends the alert data to the central station, while the acknowledgement confirms that the message was received and logged. This two‑way exchange is essential for reliable monitoring and for triggering any necessary response. Logging events is typically handled by the monitoring system, not by the transmitter itself, and simply receiving without transmitting would not convey the alarm.
