The Viking Horizon Mirage Standard Response/Quick Response Extended Coverage Sprinkler is a small solder link lever spray sprinkler intended for installation on concealed pipe systems. Equipped with a special deflector the sprinkler is designed to meet Light-Hazard density requirements for specific areas of coverage when the required minimum water supply is provided at the sprinkler. The sprinkler is installed with a low profile cover plate that fits flush to the ceiling and detaches during fire conditions when the temperature around the sprinkler approaches its operating temperature.
