The SHS-6T2CVR is an industry-first strategically hidden ceiling speaker designed specifically for areas where there is high sensitivity to clean air. The included SHS-CVR (cover) easily installs over the SHS opening to create a barrier between the building plenum and clean space. AtlasIED recommends using the SHS-6T2CVR kit when paging notifications are just as important as the air quality in an environment. Easy Installation Visually, only a 3-inch diameter lens and a micro trim ring are visible on the front of the ceiling. The SHS is an installer’s dream with an integrated rail system. All the installation parts are built into the enclosure including the tile rails, which require no rail screws for installation. Simply pull the four rails out from the enclosure and it’s ready for install, drill a three-inch hole in the ceiling tile, set the speaker through the hole and add the clean room cover.
