Bellevue, Wash.-based Aiphone introduces the DB Series hands-free answering intercom. Using just two wires to the door station and only four wires between interior stations, the DB system reduces installation time and cost, according to the company. The door unit provides a voltage output to activate a strike, eliminating not just additional wires, but also the additional door strike power supply.
The DB Series door station is surface mount with a metal faceplate and backlit call button(s). A single door station can connect to five interior stations. Interior units communicate by placing an all call announcement to all other units. Answering the all call announcement at a different interior location establishes point to point communication.
