Interphone audio GIRA 126666

Fully pre-assembled surface-mounted door station designed for vertical surface-mounted installation, allowing quick and clean fitting. The device belongs to the Gira TX_44 design line and combines an aluminium profile frame with a shatter-proof thermoplastic front plate for torsional rigidity, UV resistance and a scratch-resistant surface. The unit features theft protection with Torx screws, white LED-illuminated call button, weather-resistant speaker and a high-quality electret microphone. Signal transmission and power for audio/video components use a reverse-polarity-protected and short-circuit-proof 2-wire bus. Compact dimensions: 110 mm (width) × 19 mm (depth) × 181 mm (height).

Advantages

The pre-assembled construction and one-person start-up procedure ensure rapid installation and commissioning. Robust aluminium profile and shock-resistant thermoplastic front plate provide long-term stability and resistance to UV and mechanical wear. The 2-wire bus offers protected signal and power transmission while the speakerphone function includes echo and background-noise suppression for clear voice communication. White maintenance-free LED illumination gives even call-button lighting and the name plate can be changed without tools.
