Aiphone LEF-3, 3-Call Master Station

Analog 3-Channel Master Station

• Firstly, the LEF-3 is a selective calling open voice style master station with the capacity of up to 4 total stations. In addition, the system can be designed to meet a wide variety of needs, including any combination of master and sub stations up to its maximum capacity.
  
  
• Secondly, incoming calls from a sub or door station are annunciated with a momentary electronic mono-tone and an LED, remaining lit for approximately 20 seconds. Communication at the calling master is press-to-talk, release-to-listen.
  
  
• Thirdly, a person at the receiving station speaks hands free. In essence, the person at the master station can selectively call and talk with a person at any other sub or master station in the system. Moreover, the privacy feature on the master and selected subs prevents unauthorized monitoring from other master stations.
  
  
• In general all can be received, but communication back to the calling master will be heard only after the privacy button is disengaged. Master stations can be wall or desk mounted.
  
  
• To summarize, sub stations are available in surface or flush mount styles, with or without privacy. Outdoor stations are available in surface or flush mount styles.
