Typical Applications
Where Zerund Ceiling Speakers Perform Best The Bluetooth ceiling speaker series is purpose-built for commercial interiors where audio ambiance enhances the customer or occupant experience.
In moisture-prone areas such as bathrooms, wellness spaces and hospitality environments, lighting protection is essential. Zerund offers IP65 waterproof downlight fixtures for reliable commercial applications.Modern offices require flexible control for both sound and lighting. Pairing ceiling speakers with dimmable office LED downlights creates a comfortable environment for meetings, collaboration and daily work.
Installation & Operation
● First-Time Pairing: Power on the master unit → Enable Bluetooth on your audio source → Select "Bluetooth Audio" (or Audio 2 / Audio 3 for multi-channel) → Connected.
● Reconnection: Units automatically reconnect to the last paired device upon power-on — no manual repairing needed.
● Master-Slave Setup: Set DIP switches to Master or Slave mode before powering on. Do not adjust DIP switches while the unit is energized. One master supports unlimited synchronized slaves within the 40- meter range.
● Ceiling Compatibility: Verify track type or cutout diameter (75–85mm for embedded variants) before installation. Suitable for standard suspended ceilings, drywall, plasterboard, and magnetic track systems.

Zerund Lighting provides engineering-driven customization for commercial audio projects of any scale:
● Branded housings, finishes, and color matching (RAL/Pantone)
● Extended Bluetooth range or multi-zone controller integration
● Custom packaging and labeling for distributor programs
● Pre-configuration of master/slave assignments for turnkey installation
