This outdoor doorphone is designed to complement premise security and improve efficiency for greeting visitors and guests at a door or gate in business or residential applications. Entry is activated by a simple telephone keypress.

The intercom is full duplex capable, featuring echo cancellers and adaptive noise reduction for superior voice quality. This intercom is ideally suited for applications involving the upgrade or retrofit of an existing analog intercom where twisted pair is only available. Installation is simple by wiring the 8028 door station intercom at the entrance 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.

This door control relay can connect to any type of door release, gate activation system or access control panel. The intercom includes a 24 V 0.3 A power source for low power 24 V 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.Algo Intercom Outside Wall Flush Mount Installation

The 8028 kit includes:

  • Door Station with two face plates (brass, stainless steel)
  • Controller with 24V power supply, and
  • a bezel for surface mounting.

Please note that the Door Station can flush mount into a standard dual gang box. Mounting gaskets are included in the kit for installing the intercom in any outdoor environment.

How it Works


Visitors press the backlit call button on the intercom to dial a phone or group of phones on the attached phone system. When the call is answered, there is two-way communication with the visitor. Pressing a pre-configured door code from the telephone will activate the door control relay to allow momentary unlock of the entrance for the visitor to gain access.
