The Aiphone LEF-3C Open Voice selective-call master intercom with all-call button works with any combination of up to three Aiphone LAF and LEF Series master intercoms or LA, LE, and LS Series door and sub-master intercoms (sold separately) to enable audio communication with a visitor at a door and with other rooms within the building. The all-call button works with an Aiphone BG-10C adapter (sold separately) to broadcast a message or music to every intercom connected to the system. Three buttons with LED indicators allow the master intercom to direct a call and communicate with the desired door or sub-master intercom. Calls received from a door or sub-master intercom are indicated by a momentary chime and the corresponding LED indicator above the selectable buttons illuminating for 20 seconds. Depressing the push-to-talk button on the master intercom allows the user to talk to the specified door or sub-master intercom user, and releasing the button immediately transmits sound from the door or sub-master intercom to the master intercom. The privacy button prevents other intercom users in the system from overhearing a conversation with another intercom.
At any time, the master user can listen to audio transmissions from a specified door or sub-master intercom. The chime and audio volume is adjustable, and switching the power button to off silences the master intercom's chime alerts. The housing is white plastic and mounts semi-flush to a wall using the included mounting hardware. The system is hardwired to be powered by a 12V power supply (sold separately).
