The Aiphone LEM-3 Open Voice selective-call master intercom works with any combination of up to three Aiphone LE series door or sub-master intercoms (sold separately) to enable audio communication with a visitor at a door and with other rooms within the building. Three buttons with LED indicators allow the master intercom to direct a call and communicate with the desired door or sub-master intercom. Depressing the push-to-talk button on the master intercom allows the user to talk to the door or sub-master intercom user, and releasing the button immediately transmits sound from the door or sub-master intercom to the master for 20 seconds
