VESDA VHX-0420

Product Overview

The VESDA VHX-0420 is a Modbus Type 3 High Level Interface (HLI) designed to integrate VESDAnet networks with third-party host systems, including Building Management Systems (BMS) and Fire Alarm Control Panels (FACP). Acting as a central proxy for the network, it enables seamless bi-directional communication, providing real-time access to detailed detector status information and enabling centralized control.
