The Viking Freedom Residential Concealed Pendent Sprinkler is a small, high-sensitivity solder link and lever residential sprinkler. It is designed for installation on concealed pipe systems where the appearance of a smooth ceiling is required. The sprinkler is hidden from view by a low profile cover plate (sold seperately) installed flush with the ceiling, which detaches during fire conditions when the temperature around the sprinkler approaches its operating temperature.
