Description
RCF DP 4EN Unidirectional Voice Alarm Sound Projector
The RCF DP 4EN is a unidirectional sound projector for installations requiring directed announcement coverage. Its fullrange transducer is housed in a flameproof ABS enclosure, with an aluminium grille and bracket for the defined mounting arrangement.
The specified frequency response is 180 Hz – 16000 Hz. Rated power handling is 10 W. Maximum sound pressure level at one metre is 101 dB. These characteristics define how the component fits into the supported audio arrangement and provide the starting point for selecting the associated equipment and operating settings.
The physical specification lists depth 200 mm, diameter 137 mm, weight 1.7 kg. The enclosure material is ABS. The specified finish is Grey – RAL 7035. The productÂ’s physical format should be considered alongside the installation position, the surrounding equipment and the space required to reach its connection points.
Speaker placement should be planned around the listening area and the type of coverage required. Mounting position, distance from listeners and the surrounding room layout all affect the complete installation. The loudspeakerÂ’s specified connection method and load should be matched to the selected amplification system before the final layout is established.
For a distributed sound installation, consider the speaker position and cable route together. The chosen operating settings should remain consistent with the amplifier and the connected speaker line. Keep the relevant connection points accessible during assembly, and use the model-specific mounting instructions to establish the final orientation and physical attachment arrangement. The final arrangement should follow the documented product configuration and remain matched to the intended system components.
