REQUIREMENTS FOR LOW ENERGY POWER OPERATED DOORS
1. Activation
2. Opening
3. Closing
4. Force and Kinetic Energy
44
The following texts are excerpts from American National Standard for low energy
power-operated doors. Please refer to the full standard if necessary.
The operator shall be activated by a knowing act.
Doors shall open from closed to back check, or 80 degrees which ever occurs first, in
3 seconds or longer as required in Table I. Backcheck shall not occur before 60
degrees opening.
Total opening time to 90 degrees shall be as in Table II. If the door opens more than
90 degrees, it shall continue at the same rate as backcheck speed.
When powered open, the door shall remain at the open position for not less than
5 seconds.
Doors shall close from 90 degrees to 10 degrees in 3 seconds or longer as required in
Table I.
Doors shall close from 10 degrees to fully closed in not less than 1.5 seconds.
The force required to prevent a stopped door from opening or closing shall not
exceed 15 lbf (67 N) measured 1 in (25 mm) from the latch edge of the door at any
point during opening or closing.
The kinetic energy of a door in motion shall not exceed 1.25 lbf-ft (1.69 Nm). Table I
provides minimum times for various widths and weights of doors for obtaining
results complying with this kinetic energy.
Doors shall open with a manual force not to exceed 15 lbf (67 N) to release a latch, if
equipped with a latch, 30 lbf (133 N) to set the door in motion, and 15 lbf (67 N) to
fully open the door. The forces shall be applied at 1" (25 mm) from the latch edge of
the door.
