The Aiphone LEF-3 Open Voice Selective-Call Master Intercom is a versatile communication device that enables audio interaction with up to three connected door, sub-master, or master intercoms (sold separately). Designed for use in residential, business, or healthcare settings, it allows users to communicate with visitors at entry points and other rooms within a building. Three buttons with LED indicators let users easily select and communicate with the desired intercom unit, while the privacy button prevents conversations from being overheard by others on the system. A push-to-talk function allows for clear two-way communication, and users can listen to transmissions from selected units at any time. Adjustable chime and volume controls add to user customization, and the unit can be mounted on a desktop or wall. The LEF-3 operates on a 12V power supply (sold separately) and features durable white plastic housing.
