Xtralis VHX-1420 VESDA Modbus Type 3 HLI Wall Metal Box

The VHX-1420 is the wall-mounted VESDA Modbus Type 3 High Level Interface from Xtralis, part of the VESDA Programming and Connectivity range. It is housed in a metal enclosure designed for permanent mounting on a flat surface, eliminating the need for a separate socket module through its integrated VESDAnet interface. This design allows direct connection of a VESDAnet network to host platforms such as Building Management Systems and Fire Alarm Control Panels.

The unit operates on a 24 VDC supply with a quiescent current draw of 70 mA, resulting in a power consumption of 1.68 W. It supports up to 100 VESDA detectors across multiple series, including VLP, VLS, VLC, VLF, VLI, VFT-15, and the VESDA-E VEU, VEP, VES, and VEA ranges. Host communication is facilitated via an RS-485 interface, while configuration is performed using Xtralis software tools. Physical dimensions are approximately 11 in. x 7.3 in. x 2.2 in. (280 mm x 185 mm x 55 mm), with a weight of 4.4 lbs (2 kg). The product carries a two-year warranty and is discontinued, with a last time buy date of 31 May 2026 due to limited component availability.
