9463-01 Fire protection device socket HWD 90

HWD 90 cavity wall boxes for EI30 - EI120 fire protection walls ensure certified and fireproof electrical installation. They are now also approved for wooden walls in wood frame or wooden panel designs F30-B and F60-B. No additional measures, such as an enclosure, are necessary. The intelligent AFS technology reacts immediately to fire and heat and closes the installation opening automatically. The fire resistance class of the wall is therefore maintained and the escape route is secured. Application in all fire walls and the fire resistance up to 120 minutes ensures maximum flexibility - even in case of planning changes. At the same time, it also maintains the noise protection standard of the wall.
