Aiphone DB - Manual

A user manual for the DB Series two-wire door answering intercom system covers its core components–such as call buttons, microphones, speakers, and backlights–and highlights key functionalities like multi-station support (up to five stations per button), hands-free communication, and push-to-talk operation. The document also addresses essential setup requirements, including wiring diagrams for master and substations, transformer connections, and programming procedures for ID management in units like the DB-1SD. Technical details such as power specifications, current draw, and door release ratings are included to ensure proper installation and functionality.

The DB Series door station is surface mount with an aluminum faceplate and backlit call directory. The door stations
come in one, two, or four call button varieties and each tenant can have up to five interior stations. Multiple button
door stations allow system installation in multi-tenant buildings. Communication with the door is hands-free from any
wall mounted interior unit. After establishing a visitor’s identity, a press of the door release button activates the door
strike to allow entry. Interior units communicate by placing an All Call announcement to all other units. Answering
the All Call announcement at a different inside location establishes point-to point communication.
