Selective Call Audio Sub Master Station - Indoor Intercom Monitor with Privacy Mode and Remote Door Release (LEF Series Compatible)

The LEF-1C Sub Master Station is a purpose-built intercom unit designed for use within the LEF Series selective call audio system. Acting as an intermediary between a main master station and a door station, it gives users the flexibility to monitor incoming calls and respond on their own terms. A dedicated Privacy Button blocks incoming audio monitoring from other master stations, ensuring confidential conversations stay private. The station operates on a Push-to-Talk design, meaning you can listen in on the door station or master station silently until you choose to speak. A side-mounted Voice Volume Control lets you fine-tune incoming audio levels for comfortable communication. The built-in Remote Door Release button allows you to trigger a compatible electric door strike directly from the station, supporting a Normally Open contact rated at 24V AC/DC, 1A. The LEF-1C is also All-Call compatible, enabling it to receive system-wide announcements from LEF-10S or LEF-3L master stations. Powered by 12V DC supplied through the system, it can be mounted on a wall or placed on a desktop. Package dimensions are 8" x 6" x 2.5" and the unit weighs approximately 1.0 lb.
