For electrified trims, confirm proper functionality of the electric dogging and unlocking features․ Ensure all wiring connections are secure and compliant with local codes․ Consider potential von Mises stress on components during testing, avoiding excessive force․ Refer to Allegion US guidelines for detailed testing procedures and troubleshooting tips․
Understanding Von and Von Duprin Nomenclature
The prefix “von” in names like Von Duprin originates from German and historically indicated noble lineage, signifying “from” or “of” a particular place․ While initially denoting aristocracy – as seen with figures like Johann Wolfgang von Goethe – its modern usage is largely historical․
Von Duprin, as a brand under Allegion US, doesn’t inherently imply nobility but reflects its German origins․ The “Duprin” portion likely refers to the founder or a geographical location․ Understanding this etymology doesn’t impact installation of the 98/99 exit devices, but provides historical context․
Similarly, “Van” serves a comparable function in Dutch and Flemish names․ The distinction between “von” and “Van” relates to regional linguistic traditions․ When considering material strength during installation, remember concepts like von Mises stress are unrelated to the brand’s name origin․ The Outdoor Defense (OUT) option’s development focuses on practical engineering, not historical titles․
Von Mises Stress and Material Considerations
When installing Von Duprin 98/99 exit devices, understanding material strength is crucial, particularly concerning load-bearing components․ Von Mises stress, a yield criterion, calculates the combined stress state in a material under multi-axial loading․ This is vital for ensuring the device withstands operational forces․
The 98/99 series utilizes specific alloys chosen for their tensile strength and ductility․ Installation procedures must not compromise these material properties․ Improper tightening or forceful adjustments can induce stress concentrations, exceeding the material’s yield point․
The Outdoor Defense (OUT) option necessitates consideration of temperature variations and corrosion․ These factors affect material properties, potentially increasing susceptibility to stress corrosion cracking․ Allegion US’s material selection accounts for these conditions, but correct installation remains paramount․ Ignoring von Mises stress principles during installation could lead to premature failure, especially in high-traffic or exposed environments․
