Ritron RDC-447 DoorCom UHF Wireless Intercom

Connect visitors at your entrance directly with radio-equipped employees. The Ritron RDC-447 DoorCom is an analog UHF two-way intercom for loading docks, receiving doors, employee entrances and other fixed communication points. Staff can answer from a compatible portable radio or desktop base station while continuing their work.

Key Features

• 450–470 MHz UHF operation with 2 watts of transmitter power.
• Up to 10 programmed channels for your facility's communication requirements.
• Two-piece design: weather-resistant RDC-1 speaker/microphone box connects to an indoor radio transceiver through a 20-foot cable.
• Call alert: selectable doorbell or ringing tone identifies an intercom call.
• Flexible programming: select supported table frequencies in the field or use Ritron software for custom frequencies.
• Automatic restart when AC power returns.

Benefits and Ideal Applications

Let employees communicate with visitors before approaching the entrance. DoorCom supports delivery coordination and visitor assistance while allowing secured doors to remain closed until staff are ready to respond.

• Warehouse receiving doors and loading docks
• Employee and service entrances
• Will-call counters and pickup areas
• Lobby entrances and factory communication points

Radio Compatibility

The RDC-447 works with compatible analog UHF business radios programmed to matching frequencies and CTCSS/DCS settings. Dual-mode radios must use a compatible analog channel. Verify your existing radio model and programming before ordering.

A separate companion radio is required and is not included.
