{"product_id":"lef-3-selective-calling-open-voice-style-3-call-master-station","title":"LEF-3 Selective Calling Open Voice Style 3-Call Master Station","description":"The LEF-3 is a selective calling open voice style master station designed for flexible internal communication systems. With capacity for up to 4 total stations, it supports any combination of master and substations to meet your specific needs.\n\nIncoming calls from sub or door stations trigger a momentary electronic mono-tone and LED indicator that remains lit for approximately 2 seconds. Communication operates on a press-to-talk, release-to-listen basis at the master station, while called stations respond hands-free. The master can selectively call and communicate with any other sub or master station in the system.\n\nA built-in privacy feature on the master and selected substations prevents eavesdropping. When privacy is engaged, incoming calls can be received, but communication back to the calling master is heard only after the privacy button is disengaged.\n\nKey Features:\n- Intermixable system with master and sub stations up to maximum capacity of 11 units\n- Selective calling and monitoring capabilities\n- Push-to-talk at master, hands-free reply at called station\n- Compatible with LEF master stations and LE door stations\n- Durable ABS plastic housing\n- Selective door release functionality\n- LED and call-tone indicators for clear notification","brand":"Raztechs","offers":[{"title":"Default Title","offer_id":50005587132693,"sku":null,"price":352.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0847\/5394\/0757\/files\/1018875246_lg.jpg?v=1782902000","url":"https:\/\/www.raztechs.com\/products\/lef-3-selective-calling-open-voice-style-3-call-master-station","provider":"Raztechs","version":"1.0","type":"link"}
