1. DESCRIPTION
Viking Quick Response Extra-Large Orifice Pendent Sprinkler VK377 is a
thermosensitive glass bulb spray sprinkler available in several different finishes
and temperature 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 environments and are listed/approved as indicated in the
Approval Charts.
The extra-large orifice provides greater flows at lower pressures than standard orifice
or large orifice sprinklers. This feature allows reduced pipe sizing for hydraulically
calculated sprinkler systems, which require high densities of water. Viking Quick
Response Extra-Large Orifice Sprinklers may eliminate the need for a fire pump or
reduce the size of the pump if it is required. On existing systems, replacing large
orifice sprinklers with extra-large orifice sprinklers may provide the higher densities
required to allow an increase in the hazard classification of an occupancy.
Viking quick 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 below.

4. INSTALLATION
Refer to appropriate NFPA, FM Global, and/or any other applicable installation standards.
5. OPERATION
During fire conditions, when the temperature around the sprinkler reaches its operating temperature, the heat-sensitive liquid in the
glass bulb expands, causing the bulb to shatter, releasing the pip cap 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
Viking Sprinkler Model VK377 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.

removed from a pendent sprinkler.
Figure 2: Sprinkler cap being
removed from a pendent sprinkler.
Figure 3: Sprinkler cap being re-
moved from and upright sprinkler.
HOW TO REMOVE SHIELDS AND CAPS:
No tools are necessary to remove the shields or caps from sprinklers. DO NOT use any sharp objects to remove them! Take care
not to cause mechanical damage to sprinklers when removing the shields or caps. When removing caps from fusible ele-
ment sprinklers, use care to prevent dislodging ejector springs or damaging fusible elements. NOTE: Squeezing the sprinkler cap
excessively could damage sprinkler fusible elements.
• To remove the shield, simply pull the ends of the shield apart where it is snapped together. Refer to Figure 1.

USE THE FOLLOWING PRECAUTIONS WHEN HANDLING WAX-COATED SPRINKLERS
Many of Viking’s sprinklers are available with factory-applied wax coating for corrosion resistance. These sprinklers MUST receive
appropriate care and handling to avoid damaging the wax coating and to assure satisfactory performance of the product.
General Handling and Storage of Wax-Coated Sprinklers:
• Store the sprinklers in a cool, dry place (in temperatures below the maximum ambient temperature allowed for the sprinkler temperature rating. Refer
to Table 1 below.)
• Store containers of wax-coated sprinklers separate from other sprinklers.
• Protect the sprinklers during storage, transport, handling, and after installation.
• Use original shipping containers.
• Do not place sprinklers in loose boxes, bins, or buckets.
Installation of Wax-Coated Sprinklers:
Use only the special sprinkler head wrench designed for installing wax-coated Viking sprinklers (any other wrench may damage
the unit).
• Take care not to crack the wax coating on the units.
• For touching up the wax coating after installation, wax is available from Viking in bar form. Refer to Table 1 below. The coating MUST be repaired after
sprinkler installation to protect the corrosion-resistant properties of the sprinkler.
• Use care when locating sprinklers near fixtures that can generate heat. Do not install sprinklers where they would be exposed to temperatures exceed-
ing the maximum recommended ambient temperature for the temperature rating used.
• Inspect the coated sprinklers frequently soon after installation to verify the integrity of the corrosion resistant coating. Thereafter, inspect representative
samples of the coated sprinklers in accordance with NFPA 25. Close up visual inspections are necessary to determine whether the sprinklers are being
affected by corrosive conditions.
Never install sprinklers that have been dropped, damaged, or exposed to temperatures in excess of the maximum ambi-
ent temperature allowed.
Refer to the appropriate current technical data pages for complete care, handling, and installation instructions. Data
pages are included with each shipment from Viking or Viking distributors. They can also be found on the Web site at www.
