DESCRIPTION <br /> Viking Model A-1, B-1, and C-1 Sprinkler Water Shields and Guards are used in <br /> conjunction with Viking frame style upright or pendent sprinklers where allowed <br /> 77�- <br /> by the approvals. (Refer to the Approval Chart) The guards are hard-wire cages <br /> designed to encase the sprinklers and protect them from mechanical damage.They <br /> are recommended for areas where sprinklers are installed at a low elevation and/or <br /> near a high degree of human or mechanical activity. <br /> Water shields protect the sprinklers' heat-sensing operating element from water <br /> spray discharge from sprinklers located at a higher elevation. Viking frame style Model A-1 Sprinkler Guard <br /> sprinklers with Model B-1 or C-1 Water Shields are converted to intermediate level/ <br /> rack storage sprinklers.They may be used in any application where water shielding <br /> is required, such as in-rack sprinkler systems, under grating, on pilot sprinklers for <br /> deluge systems, and outdoors as a weather shield. <br /> NOTE: Sprinkler water shields and guards are not designed to be used on <br /> sprinklers installed in recessed escutcheons. <br /> 2.
