Description
Modbus register access is what the Type 3 interface offers, and the standard unit is the form of it that does not have to be permanently fixed in place.
Detectors covered are the VESDA VLP, VLS, VLC, VLF, VLI and VFT-15, together with VESDA-E VEU, VEP, VES and VEA.
VHX-0420 is the VESDA Modbus Type 3 HLI Standard from Xtralis, a standard unit used to provide a flexible solution where permanent mounting is not required. It integrates a VESDAnet network with a host monitoring platform.
The VESDA zone equates to the Modbus address field, which allows the host to retrieve the overall status of the VESDAnet network as well as performing certain VESDA device configuration updates. The host is able to monitor and control VESDA devices on the VESDAnet network by reading and writing into registers in the Modbus map.

Supply is 24 VDC at 70 mA (Quiescent), with power consumption of 1.68 W (Quiescent). The unit measures 188 mm x 98 mm x 40 mm and weighs 0.9 lbs (0.4 kg), and up to 100 detectors are supported. RS-232 runs to the HOST and RS-485 to VESDAnet, through a VESDAnet Socket (VRT-300). A VESDA HLI is recommended to be used for secondary monitoring, taking fire alarms and other notifications off a VESDAnet network; put to primary reporting, it must be listed as part of an approved fire system which is compliant to local codes and standards.
