The HES 9600 model series electric strike recently achieved UL listing under ANSI Severe Windstorm requirements for latching hardware under ANSI/SDI-BHMA 250.13. A "severe windstorm" is defined by the BHMA and ANSI standard as a weather event with sustained winds or gust of 110 to 150 miles per hour. To meet listing requirements, an electric strike must preserve the closed door state and be functional after withstanding impacts of 350 ft-lbs, which is roughly equal in force to a 9 pound section of 2 x 4 flying at 50 feet per second and hitting the opening end on. It must then survive pressure variances of + 60ft-lbs of pressure over 3500 cycles.
The 9600 is part of the HES Genesis family of Surface Mount strikes and is used with rim exit devices of up to ¾".
