1. DESCRIPTION
Viking Model XG Sprinkler Guards and XWU Water Shields are used in conjunction
with Viking XT1 style sprinklers where allowed by the approvals. (Refer to the
Approval Charts) The guards are hard-wire cages designed to encase the
sprinklers and protect them from mechanical damage. They are recommended for
areas where sprinklers are installed at a low elevation and/or near a high degree
of human or mechanical activity.
Water shields protect the sprinkler’s heat-sensing operating element from water
spray discharge from sprinklers located at a higher elevation. Viking XT1 style
sprinklers with Model XWU or F-1 Water Shields and/or XG Guards are converted
to intermediate level/rack storage sprinklers. They may be used in any application
where water shielding is required, such as in-rack sprinkler systems, under grating,
on pilot sprinklers for deluge systems, and outdoors as a weather shield.
NOTE:Sprinkler water shields and guards are not designed to be used on
sprinklers installed in recessed escutcheons.
