Matrix values are in seconds.
Doors of weights and widths can be calculated using the formula:
WHERE: T = Time, seconds
D = Door width, inches (mm)
W = Door weight, lbs (kg)
The values for “T” time have been rounded up to the nearest half second. These values are based on
kinetic energy of 1.25 lbf-ft.
The value for the 30 inch wide, 100 pound door actually calculates to 2.5 seconds with rounding. 3.0
seconds was used as a more conservative value.
