Aiphone DB-1SD Sub Master Audio Station

Product Description

The AIPHONE DB-1SD is a sub master audio station designed for audio-only intercom systems. It functions as a secondary master control point within a multi-station intercom network, allowing communication between entry points and interior locations without a video component. Licensed low-voltage technicians and security system installers typically deploy this unit in residential and light commercial settings where a primary master station is already part of the system architecture. The DB-1SD is sold as a single unit and fits within the audio-only intercom product category.

This sub master audio station is intended for use in audio-only intercom configurations where more than one master-level station is required. Common installations include multi-room residential setups, small office environments, and building entry systems where voice communication between stations is the primary requirement. It operates alongside a primary master station rather than as a standalone controller.

Installation Notes

Installation should be performed by a licensed low-voltage or communications technician in accordance with applicable NEC requirements for low-voltage wiring. Power down the entire intercom system before connecting or disconnecting any station. Follow the system wiring diagram provided by the manufacturer to ensure correct bus connections between master, sub master, and door stations. Do not attempt to use this unit as a standalone master station in systems that require a primary master controller.
