    HLI-2W2 - Overview

    The ClearCom HelixNet HLI-2W2 is a dual 2-wire interface module for the HelixNet HMS-4X Intercom System Main Station (sold seperately). HelixNet®is a fully networked partyline intercom, supporting up to 24 channels and independent Program Audio over XLR, LAN and WAN.

    HLI-2W2's 2-wire analog partyline interface are assignable to any channel in the HelixNet system and provide connectivity to powered Clear-Com or RTS-TW analog partyline systems. Level control and VOX/Gate capability is provided for each interface to accommodate the connected system. HLI-2W2 include call signaling and remote mic kill circuits when used with compatible Clear-Com and RTS-TW partyline devices.

    HLI-2W2 can be added to any HMS-4X main station with an available option slot. Once installed, any channel can be independently assigned to either 2-wire port locally on the HMS-4X front panel or centrally from the Core Configuration Manager.

    Please Note! This item is just one component of a larger system.
