Example
: 18264MB/W = VK202 with White Polyester Finish and 155 °F (68 °C) Nominal temperature rating. This sprinkler is to be installed into an
area with a maximum ambient temperature of 100 °F (38 °C) meaning if the area will experience temperatures above the maximum ambient rating,
you shall use a higher temperature-rated sprinkler.

Footnotes
1.
Where a dash (-) is shown in the Finish suffix designation, insert the desired Temperature Rating suffix. See example above.
2.
Based on NFPA 13, NFPA 13R, and NFPA 13D. Other limits may apply, depending on fire loading, sprinkler location, and other requirements of the Authority Having
Jurisdiction. Refer to specific installation standards.
3.
UL Listed as corrosion resistant.
4.
FM Approved corrosion resistant.
5.
The corrosion resistant and corrosion proofing coatings have passed the standard corrosion test required by the approving agencies indicated in the Approval Chart(s).
These tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coatings are compatible with or
suitable for the proposed environment. For automatic sprinklers, the coatings indicated are applied to the exposed exterior surfaces only. Note that the spring is exposed
on sprinklers with Polyester and ENT coatings. For ENT coated automatic sprinklers, the waterway is coated.
6.
Sprinklers of Ultra-High temperature rating are intended for use inside ovens, dryers, or similar enclosures with normal operating temperatures above 300 °F (149 °C).
Where the ambient temperature around the Ultra-High temperature rated sprinkler is significantly reduced below 300 °F (149 °C), response time may be severely retarded
7.
Wax melting point is 170 °F (76 °C) for 286 °F (141 °C) temperature rated sprinklers. For more inforamation regarding wax coatings, refer to
8.
Allows use from the floor by attaching a length of 1” diameter CPVC tubing to the tool. Ideal for sprinkler cabinets. Refer to
