Lee Electric bc305 Chime Buzzer Concealed Terminals

Product Description

The LEE ELECTRIC bc305 is a 2-coil chime buzzer designed for low-voltage doorbell and signaling applications. It features a 3-inch diameter gong and concealed terminals for a clean, finished appearance after installation. The bc305 suits residential entry signaling systems and is typically installed by electricians or skilled trades performing low-voltage wiring work. Its dual-coil design produces a two-tone chime sound, distinguishing front-door and back-door signals in standard doorbell configurations.

The bc305 is suited for residential signaling applications where a surface-mounted or flush-installed chime unit is required. The concealed terminal design keeps wiring hidden once the unit is mounted, making it appropriate for finished interior walls in homes and light commercial entry points. Installers working on doorbell system upgrades or new construction rough-in will find the compact 3-inch gong footprint compatible with standard chime mounting locations.
