Viking EC/QREC Pendent Sprinkler VK534 is a thermosensitive spray sprinkler available in several different finishes and temperature ratings to meet varying design requirements. The extra-large orifice produces the flows required to meet Light and Ordinary Hazard density re- quirements at lower pressures than standard orifice or large orifice sprinklers. The glass bulb operating element and special deflector characteristics meet the challenges of quick RESPONSE extended coverage standards.

2 Pendent Sprinkler VK534 is cULus Listed as standard and quick RESPONSE . The special Polyester and Electroless Nickel PTFE (ENT) coatings can be used in decorative applications where colors are desired. In addition, ENT coating has been investigated for installation in corrosive atmospheres. See Approval Charts. 2. LISTINGS AND APPROVALS. cULus Listed: Category VNIV. Refer to Approval Chart 1 and Design Criteria cULus Listing requirements. NOTE: As of May 2018 all logos have been re- moved from the wrench boss. 3. TECHNICAL DATA. Specifications: .

Ordering Information: (Also refer to the current Viking price list.). Order Viking EC/QREC Pendent Sprinkler VK534 by first adding the appropriate suffix for the sprinkler finish and then the appro- priate suffix for the temperature rating to the sprinkler base part number.

4 Finish Suffix: Brass = A, Chrome = F, White Polyester = M-/W, Black Polyester = M-/B, and ENT = JN. Temperature Suffix: 135 F (57 C) = A, 155 F (68 C) = B, 175 F (79 C) = D, 200 F (93 C) = E, and 286 F (141 C) = G. For example, sprinkler VK534 with a Brass finish and a 155 F (68 C) temperature rating = Part No. 08340AB. Available Finishes And Temperature Ratings: Refer to Table 1.

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.

Other limits may apply, depending on fire loading, sprinkler location, and other requirements of the Authority Having Jurisdiction. Refer to specific installation standards. 3. For automatic sprinklers, the coatings indicated are applied to the exposed exterior surfaces only.

8 Note that the spring is exposed on sprinklers with Polyester coatings. 4. The corrosion-resistant coatings have passed the standard corrosion test required by the approving agencies indicated in the Approval Chart. These tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coatings are compat- ible with or suitable for the proposed environment. For ENT sprinklers, all exposed surfaces and the waterway are coated, but note that the spring is exposed. Step 1: Carefully slide the wrench sideways around the deflector, ensuring en- gagement with the sprinkler wrench flats. Pendent Sprinkler Sprinkler wrench 13577W/B**. must be used for installing wax coated sprinklers. Step 2: Carefully press the wrench upward and ** A 1/2 ratchet is required ensure engagement with the sprinkler wrench flats.
