5.4 Additional Approval Requirements and Details
Refer to Table 5.1 for approved configurations allowed by each of the following approvals.
•
CE CPR: Standard EN 12259-1:1999 +A3:2006; Declaration of Performance DOP_XT1A.
•
LPCB: Standard EN 12259-1:1999 +A3:2006; Certificate Number 096m.
•
VdS: Standard EN 12259-1:1999 +A3:2006; Certificate Number G 422003.
•
UKCA: Standard EN12259-1:1999 +A3:2006; Declaration of Conformity UKCA DOC_S5048.
•
MED: Standard EN 12259-1:1999 +A3:2006; Declaration of Conformity DOC_MED_XT1.
For specific application and installation requirements, refer to the latest applicable governmental codes, ordinances,
and standards for the installation location.
5.5 Corrosion Resistant Coatings
The corrosion resistant coatings have passed the standard corrosion tests required by the approving agencies and are
listed and approved as indicated in Table 5.1. These tests do not represent all possible corrosive environments. The
Electro-less Nickel PTFE (ENT) finish passed the UL 199 thirty day corrosion test and is cULus listed and FM
Approved as corrosion resistant. For automatic sprinklers, the ENT coating is applied to all exposed exterior surfaces,
including the waterway.
Prior to installation, verify that the coatings are compatible with, or suitable for, the proposed environment. The ENT
finish has not been evaluated for environments containing chlorine, such as indoor swimming pools. The ENT finish is
not recommended for these applications.
5.6 Sprinkler Guards and Water Shields
The sprinkler is approved for use with the Model XG Sprinkler Guard and the Model XWU upright water shield. Refer to
the Guards and Water Shields for XT1 Sprinklers technical data sheet for more information.
5.7 Available Temperature Ratings
Viking sprinklers are available in several temperature ratings that relate to a specific temperature classification.
Applicable installation rules mandate the use and limitations of each temperature classification. The maximum
expected ceiling temperature must be known before selecting the appropriate temperature classification.
Before ordering a sprinkler, use a maximum-reading thermometer to determine the maximum expected temperature. In
addition, refer to recognized installation rules which may require a higher temperature classification to be used. The
rules may depend upon the following criteria:
•
sprinkler location
•
occupancy classification
•
commodity classification
•
storage height
•
other nearby hazards
In all cases, the maximum expected ceiling temperature dictates the lowest allowable temperature classification.
Sprinklers located immediately adjacent to a heat source may require a higher temperature rating.
