What is a Duplex in terms of alarm communications?

A Duplex in the context of alarm communications refers specifically to a method that allows two-way transmission of signals between devices. This is significant in alarm systems because it enables real-time communication between the monitoring station and the alarm system. With two-way communication, information can be both sent and received, allowing for more interactive control and feedback, such as acknowledging alerts or adjusting settings from a remote location.

This capability is crucial for ensuring effective monitoring and response in alarm systems, as it permits operators to verify alarms and communicate with users or service personnel promptly. Two-way communication systems often enhance security measures, providing a more dynamic and responsive approach compared to one-way systems, which can only transmit data in a single direction without the ability for acknowledgment or control from the receiving end.
