This intercom is ideally suited for applications involving the upgrade/retrofit of an existing analog intercom to IP where twisted pair is only available. Installation is simple by wiring the 8028 door station intercom at an entrance or gate to a controller located inside the premise. The separate controller ensures that both the network connection and door opening control relay of the 8028 cannot be tampered with from the public-facing intercom. All door strikes and access control systems that provide a contact closure are compatible with the 8028.
