1. DESCRIPTION
The Viking Micromatic®Standard Response Upright VK100 Sprinkler is a small, ther-
mosensitive, glass-bulb spray sprinkler available in several different finishes and tem-
perature ratings to meet design requirements. The special Polyester and Electroless
Nickel PTFE (ENT) coatings can be used in decorative applications where colors are
desired. In addition, these coatings have been investigated for installation in corrosive
atmospheres and are listed/approved as corrosion resistant as indicated in the Approval
Charts. (Note: FM Global approves the ENT coating as corrosion resistant. FM Global has
no approval classification for Polyester coatings as corrosion resistant.)
Viking standard response sprinklers may be ordered and/or used as open sprinklers (glass
bulb and pip cap assembly removed) on deluge systems. Refer to Ordering Instructions.

Ordering Information: (Also refer to the current Viking price list.)
Order Micromatic®Standard Response Upright VK100 by first adding the appropriate suffix for the sprinkler finish and then the
appropriate suffix for the temperature rating to the sprinkler base part number.
Finish Suffix: Brass = A, Chrome = F, White Polyester = M-/W, Black Polyester = M-/B, Wax Coated = C, Wax Over Polyester = V-/W,
ENT = JN
Temperature Suffix: 135 °F (57 °C) = A, 155 °F (68 °C) = B, 175 °F (79 °C) = D, 200 °F (93 °C) = E, 212 °F (100 °C) = M, 286 °F
(141 °C) = G, 360 °F (182 °C) = H, 500 °F (260 °C) = L, OPEN = Z (PTFE only).
For example, sprinkler VK100 with a 1/2” thread, Brass finish and a 155 °F (68 °C) temperature rating = Part No. 12986AB

4. INSTALLATION
Refer to appropriate NFPA Installation Standards.
5. OPERATION
During fire conditions, the heat-sensitive liquid in the glass bulb expands, causing the glass to shatter, releasing the pip cap and
sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern
to extinguish or control the fire.
6. INSPECTIONS, TESTS AND MAINTENANCE
Refer to NFPA 25 for Inspection, Testing and Maintenance requirements.
7. AVAILABILITY
The Viking Micromatic®Standard Response Upright Sprinkler VK100 is available through a network of domestic and international
distributors. See The Viking Corporation web site for the closest distributor or contact The Viking Corporation.

Footnotes
1The sprinkler temperature rating is stamped on the deflector.
2Based on NFPA-13. Other limits may apply, depending on fire loading, sprinkler location, and other requirements of the Authority Having Jurisdiction.
Refer to specific installation standards.
3Sprinklers 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.
4The corrosion-resistant coatings have passed the standard corrosion test required by the approving agencies indicated in the Approval Charts. These
tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coatings are com-
patible 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.
5Wax melting point is 170 °F (76 °C) for 286 °F (141 °C) temperature rated sprinklers.
