The 8028 doorphone is an outdoor rated SIP compliant intercom, designed to complement premise security and improve efficiency for greeting visitors and guests at a door or gate in business or residential applications. Any telephone or device in the UC environment can communicate with the 8028, with entry activated by a simple telephone keypress.

The 8028 SIP Doorphone eliminates the need for an ATA or FXS port. The intercom is full duplex capable, featuring an echo canceller for superior voice quality.

This intercom is ideally suited for applications involving the upgrade/retrofit of an existing analogue 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.

The 8028 door control relay can connect to any type of door release, gate activation system or access control panel. The intercom includes a 24V 0.3 A power source for low power 24V DC door strikes (customer provided). Additionally, there are low current programmable inputs and outputs at both control unit and intercom station for door sensing, door unlock switch, door unlock override, auxiliary call buttons, or telephone status such as ringing or in-use.
