About
- Von Duprin 98/99 Series Grade 1 wide-stile pushpad exit devices for high-abuse commercial and institutional openings, in rim (99), surface vertical rod (9927), concealed vertical rod (9947) and mortise (9975) configurations, the 98 has a smooth end cap and the 99 a grooved one, otherwise identical. Fire-rated versions carry the -F suffix
- Falcon covers the same functions at the value tier.
Application
Required on stair and final exit doors serving assembly, educational and high-occupancy spaces under NFPA 101. The device must release with a single motion of not more than 67 N applied anywhere along the bar, which is why an exit door fitted with a separate deadbolt or a night latch fails inspection even when the panic device itself is correct. Fire-rated devices have no dogging feature, because a fire exit device must latch every time the door closes.
Standards & Reference 6 cited
UL 305
Panic hardware: the North American listing for exit devices, the counterpart to EN 1125.
UL 10C
The positive pressure fire test for door assemblies. Positive pressure drives hot gas through any gap between door and frame, which makes it the more demanding test and the one North American codes now call for.
NFPA 80
Not a test but a compliance standard: how fire doors are installed, inspected and maintained, including the annual inspection and the requirement that every fire door self-closes and positively latches.
NFPA 101
The Life Safety Code: egress width, travel distance and door operation on an escape route.
ADA 2010 Standards
The American accessible design requirements as they apply to an opening: clear width, maximum opening force, and hardware that works without tight grasping or twisting.
