DACS stands for Digital Alarm Communicator System.

• A. Digital Alarm Communicator System
• B. Digital Alarm Control System
• C. Data Alarm Communication System
• D. Digital Alert Communications System

Answer: (A)

In alarm system terminology, DACS describes the component that sends alarm signals from the control panel to a central monitoring station. It stands for Digital Alarm Communicator System, which highlights three ideas: the data is transmitted in digital form, it relates to an alarm event, and it uses a communicator device to relay that information. This exact wording is the standard term used to describe the transmission pathway from the panel to the monitoring center, so it best fits the acronym. The other options mix up the function or use nonstandard wording: they suggest the control side, use a generic “data” term, or replace “Communicator” with a different word like “Alert,” which isn’t the conventional term in practice.
