IKB-12 and HRI-12 intercom stations are designed to be a part of the HCS Industrial Intercom System providing a high-capacity single channel partyline intercom to intercom stations with point-to-point and point-to-multipoint audible and visual call signalling with caller identification. The stations are flush mount installation on an electrical back box. They include an active handset cradle which detects the handset and places the station into the partyline when taken off hook. 

HCS system is configured using a browser-based tool accessed from the HMS-4X main station, running the HCS firmware, using a web browser. Users can create Profiles for the IKB/HRI stations and assign point-to-point and point-to-multipoint call signals to the stations buttons and GPI.

The HS-6 is a push-to-talk switch with a 4-pin female XLR-connector.
