The “Minimum Closing Time” tables on the following pages reflect an average kinetic energy of
7.37 foot pounds (2.50 foot pounds, nudging) and provide the minimum code closing times for
most normal door configurations and sizes (normal and nudging operation).
When using the tables, consider:
• Closing Time/Distance: For side opening doors, code distance starts two-inches (2”) from
the jamb and ends two-inches (2”) from full close. For center opening doors, code distance
starts one-inch (1”) from the jamb and ends one-inch (1”) from full close.
• Average Kinetic Energy (7.37 foot pounds): Table times are based on this energy calcula-
tion. Calculations include “equipment rigidly connected thereto”, all hangers, rollers,
clutches, releases, closers, and reopening devices, and the rotational inertia of the motor
and operator.
• Actual Kinetic Energy (peak energy, 17.00 foot pounds): Using MCE equipment and fol-
lowing instructions carefully, you should not exceed the actual kinetic energy requirement
if your door closing time complies with the time shown in the table for your door.
• Reduced/Nudging Kinetic Energy (2.50 foot pounds): If the performance requirements of
the job allow, nudging speed closing time can safely be calculated as twice the normal clos-
ing time. If performance demands greater speed, please contact MCE Technical Support
for assistance.
