What features are commonly found in modern alarm systems?

The selection of features that are commonly found in modern alarm systems includes communicators, textual location identification, and graphical alarm panels.

Communicators are vital components of alarm systems as they facilitate communication between the alarm system and monitoring services, ensuring prompt response to any triggering events. They can utilize various transmission methods, including cellular networks or internet protocols, allowing for diverse communication capabilities.

Textual location identification is essential for quickly conveying information about the specific location where an alarm has been activated. This feature enhances response efficiency by allowing first responders to address incidents at the exact site, reducing confusion in emergency situations.

Graphical alarm panels provide a user-friendly interface for monitoring and managing alarm systems. These panels often display information visually, including diagrams of the premises with indication of which zones or detectors have been activated, making it easier for users to understand system status at a glance.

While the other options present useful features, they either include less common technologies or do not encapsulate the key advancements in modern alarm systems as effectively as the chosen answer.
