1. DESCRIPTION

Viking Micromatic® and MicromaticHP® Standard Response Pendent Sprinklers are
small, thermosensitive, glass-bulb spray sprinklers available in several different fin­ishes, temperature ratings, and K-Factors to meet design requirements. The special
Polyester and Teflon® 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 cULus listed as corrosion resistant as indicated in the Approval
Chart. (Note: FM Global has no approval classification for Teflon® and 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 on page 11b.

Ordering Information: (Also refer to the current Viking price list.)

Order Micromatic® and MicromaticHP® Standard Response Pendent Sprinklers by first adding the appropriate suffix for the sprin-

kler finish and then the appropriate suffix for the temperature rating to the sprinkler base part number.

Finish Suffix: Brass = A, Chrome-Enloy® = F, White Polyester = M-/W, Black Polyester = M-/B, Black Teflon® = N, Wax Coated = C,

Wax Over Polyester = V-/W

Temperature Suffix (°F/°C): 135°/57° = A, 155°/68° = B, 175°/79° = D, 200°/93° = E, 212°/100° = M, 286°/141° = G, 360°/182° = H,

500°/260° = L, OPEN = Z (Teflon

For example, sprinkler VK102 with a 1/2” thread, Brass finish and a 155 °F/68 °C temperature rating = Part No. 10139AB

only).

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® and MicromaticHP® Standard Response Pendent
Sprinklers are available through a network of domestic and international
distributors. See The Viking Corporation web site for the closest distributor
or contact The Viking Corporation.

8. GUARANTEE

For details of warranty, refer to Viking’s current list price schedule or contact

Sprinklers of Ultra-High temperature rating are intended for use inside ovens, dryers, or similar enclosures with normal oper-

ating 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.

The corrosion-resistant coatings have passed the standard corrosion test required by the approving agencies indicated

on pages 11 d-e. 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 Teflon
