VHX-1420, VESDA® Modbus Type 3 High Level Interface

VESDA® Modbus type 3 HLIs act as a proxy for all VESDA devices on the VESDAnet™ network, providing access to rich status information available from VESDA detectors, as well as the ability to control and configure these devices. Alarms are reported to the host within seconds of a detector reaching an alarm condition. Exact performance is dependent on the polling strategy and size of the monitored network.

These devices are housed in a metal enclosure, which allows permanent mounting on a flat surface. With a built-in VESDAnet interface, there's no need a remote VESDAnet socket module, which makes these wall-mounted HLIs a cost-effective solution to interface requirements.
