It supports a maximum capacity of 4 stations total, allowing any combination of sub stations and master stations within that limit. The lef-3c operates in an open voice format, meaning communication channels remain open without requiring a push-to-talk action. Licensed low-voltage technicians and security system installers typically handle this type of equipment in both residential and light commercial settings.\u003c\/p\u003e\n\u003cp\u003eThe lef-3c fits applications where a compact, wall-recessed master station is needed to manage calls across a limited number of intercom points. Typical install scenarios include small office entry systems, residential multi-room intercom setups, and light commercial door communication systems. The unit supports an all-call function to broadcast to all stations simultaneously, though this feature requires the BG-10C accessory. Any combination of sub and master stations can be used as long as the total count does not exceed 4.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSemi-flush mount design for clean, recessed wall installation\u003c\/li\u003e\n  \u003cli\u003eSelective call capability allows direct station-to-station communication\u003c\/li\u003e\n  \u003cli\u003eOpen voice operation eliminates push-to-talk requirements\u003c\/li\u003e\n  \u003cli\u003eSupports up to 4 stations total in any sub and master combination\u003c\/li\u003e\n  \u003cli\u003eAll-call function broadcasts to all stations in the system when used with BG-10C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe lef-3c supports up to 4 total stations using any combination of sub stations and master stations within the same system.

Power down the intercom system completely before wiring or mounting any station. Semi-flush mount installations require a suitable wall cutout and backbox to recess the unit properly. Do not exceed the 4-station system capacity, as doing so may result in unreliable operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStation Type\u003c\/strong\u003e: Semi-Flush Mount Master Station\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCall Type\u003c\/strong\u003e: Selective Call, Open Voice\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Station Capacity\u003c\/strong\u003e: 4 stations\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAll-Call Support\u003c\/strong\u003e: Yes, requires BG-10C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AIPHONE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: lef-3c\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIPHONE","offers":[{"title":"Default Title","offer_id":51525261132082,"sku":"LEF-3C","price":283.21,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/LEF-3C_500x375_0e6e1b5e-b767-43da-bf5a-430fedf40817.jpg?v=1785468757","url":"https:\/\/voomisupply.com\/products\/aiphone-lef-3c-3-call-semi-flush-master-station","provider":"Voomi Supply","version":"1.0","type":"link"}
