Technical overview
The Gent S4-FLUSH is an S-Quad semi-flush fixing kit comprising a main assembly and trim ring, designed to semi-flush mount S-Quad devices into ceiling tiles. Moulded in RAL 9010 ABS, it weighs 164g with the trim ring and measures 174mm in diameter by 50mm deep, fitting a 140mm cut-out hole. Installed in this configuration, the kit delivers enhanced volume output of sound and speech, improving acoustic performance compared with standard surface mounting.
Storage temperature ranges from -20°C to 70°C, with ambient operating limits of -10°C to 50°C and relative humidity up to 95% non-condensing between 5°C and 45°C. The kit suits S-Quad devices, where the base locates into the semi-flush shroud, and a metal back box can be secured to the rear using appropriate fixing screws. An optional 140mm or 146mm Bi-Metal Holesaw may be used to prepare the ceiling tile, with full wiring details provided in the installation manual.
