Clear-Com HLI-4W2 HelixNet 4-Wire Interface Module

In combination with a HelixNet Main station, the HLI-4W2 interface module allows seamless connectivity to almost all common four-wire audio paths. Plug the HLI-2W2 into one of the rear panel slots of the main station, (sold separately) and a pair of RJ-45 connectors on the HLI-4W2 send the audio to connected intercom lines such as Clear-Com or RTS, assignments can be made via the main station menu. Requires external partyline power source.
