Aiphone LEF-3C 3-Call Semi-Flush Mount Master Station

Streamline voice communication for security and monitoring teams with the Aiphone LEF-3C intercom master station. This 3-call selective calling master provides targeted, reliable two-way communication so staff can coordinate responses without broadcasting to the entire network. The compact semi-flush mount form factor (6.1" W x 8.3" H x 1.4" D) delivers a neat, professional installation at reception desks, guard stations, or control rooms. Operates on 12V DC and supports an intermixable system of masters and subs (up to system capacity), allowing scalable deployment across facilities.

The LEF-3C pairs push-to-talk operation at the calling master with hands-free response at the called station for clear, efficient exchanges. LED call indicators and an electronic call tone ensure incoming calls are noticed immediately, while the built-in privacy feature prevents eavesdropping between masters — essential for secure operations and sensitive surveillance coordination. NDAA and TAA compliance simplify procurement for government and enterprise projects. Ideal for security, access control, and surveillance applications — add the LEF-3C to your communication network for dependable site-wide monitoring and control.
