This Viking™ VK636 Mirage ELO (Extra-Large Orifice) EC/QREC Concealed Pendent Fire Sprinkler is a Quick Response, Extended Coverage Concealed Pendent fire sprinkler head, activating at 165F (74C) with a 11.2 K-Factor, and is rated for Light Hazard occupancies. Each Concealed Pendent head features a heat-sensitive fusible link assembly, standard 3/4 in. NPT threads, and a brass frame with a bronze deflector.
VK636 includes a pre-assembled threaded adapter for easy installation of a low-profile cover plate with up to 1/2” (13 mm) vertical adjustment. The two-piece design allows for sprinkler installation and testing before attaching the cover plate. The "push-on" and "thread-on" cover plate options ensure easy installation after system testing and ceiling finishing. Available VK636 Mirage ELO Cover Plates Listed Below.
The Viking™ Mirage ELO VK636 is a glass-bulb sprinkler designed for concealed pipe systems, ideal for areas where a smooth ceiling appearance is preferred. With a K-factor of 11.2, the sprinkler produces flows required to meet Light Hazard density requirements at lower pressures than 5.6K or 8.0K sprinklers.
The Viking™ Quick Response Extra-Large Orifice Sprinkler delivers higher water flow at lower pressures compared to standard or large orifice sprinklers, making it ideal for areas with limited water pressure. This design may reduce or eliminate the need for a fire pump. In existing systems, upgrading to extra-large orifice sprinklers can provide the increased water density needed to support higher hazard classifications.
This is a Quick Response, Extended Coverage Concealed Pendent sprinkler with a maximum working water pressure of 175 PSI (12 BAR). The VK636 Mirage ELO Sprinkler pairs reliable fire protection with a clean, flush profile. Using a heat-activated fusible link assembly, this automatic fire sprinkler opens when ambient temperatures reach the sprinkler’s listed activation temperature, drenching the area surrounding a fire to keep it in its place of origin.
