Sec. 1211.7  Inherent entrapment protection requirements.

    (a) Other than the first 1 foot (305mm) of travel as measured over 
the path of the moving door, both with and without any external 
entrapment protection device functional, the operator of a downward 
moving residential garage door shall initiate reversal of the door 
within 2 seconds of contact with the obstruction as specified in 
paragraph (b) of this section. After reversing the door, the operator 
shall return the door to, and stop at, the full upmost position, unless 
an inherent entrapment circuit senses a second obstruction or a control 
is actuated to stop the door during the upward travel. Compliance shall 
be determined in accordance with paragraphs (b) through (i) of this 
section.
    (b) A solid object is to be placed on the floor of the test 
installation and at various heights under the edge of the door and 
located in line with the driving point of the operator. When tested on 
the floor, the object shall be 1 inch (25.4 mm) high. In the test 
installation, the bottom edge of the door under the driving force of the 
operator is to be against the floor when the door is fully closed. For 
operators other than those attached to the door, the solid object is to 
be located at points at the center, and within 1 foot of each end of the 
door.
    (c) An operator is to be tested for compliance with paragraph (a) of 
this section for 50 open-and-close cycles of operation while the 
operator is connected to the type of residential garage door with which 
it is intended to be used or with the doors specified in paragragh (e) 
of this section. For an operator having a force adjustment on the 
operator, the force is to be adjusted to the maximum setting or at the 
setting that represents the most severe operating condition. Any 
accessories having an effect on the intended operation of entrapment 
protection functions that are intended for use with the operator, are to 
be attached and the test is to be repeated for one additional cycle.
    (d) For an operator that is to be adjusted (limit and force) 
according to instructions supplied with the operator, the operator is to 
be tested for 10 additional obstruction cycles using the solid object 
described in paragraph (b) of this section at the maximum setting or at 
the setting that represents the most severe operating condition.
    (e) For an operator that is intended to be used with more than one 
type of door, one sample of the operator is to be tested on a sectional 
door with a curved track and one sample is to be tested on a one-piece 
door with jamb hardware and no track. For an operator that is not 
intended for use on either or both types of doors, a one-piece door with 
track hardware or a one-piece door with pivot hardware shall be used for 
the tests. For an operator that is intended for use with a specifically 
dedicated door or doors, a representative door or doors shall be used 
for the tests. See the marking requirements at Sec. 1211.16.
    (f) An operator, using an inherent entrapment protection system that 
monitors the actual position of the door, shall initiate reversal of the 
door and shall return the door to, and stop the door at, the full upmost 
position in the event the inherent door operating ``profile'' of the 
door differs from the originally set parameters. The entrapment 
protection system shall monitor the position of the door at increments 
not greater than 1 inch (25.4 mm). The door operator is not required to 
return the door to, and stop the door at, the full upmost position when 
an inherent entrapment circuit senses an obstruction or a control is 
actuated to stop the door during the upward travel.
    (g) An operator, using an inherent entrapment protection system that 
does not monitor the actual position of the door, shall initiate 
reversal of the door and shall return the door to and stop the door at 
the full upmost position, when the lower limiting device is not actuated 
in 30 seconds or less following the initiation of the close cycle.

[[Page 326]]

The door operator is not required to return the door to and stop at the 
full upmost position when an inherent entrapment circuit senses an 
obstruction or a control is actuated to stop the door during the upward 
travel. When the door is stopped manually during its descent, the 30 
seconds shall be measured from the resumption of the close cycle.
    (h) To determine compliance with paragraph (f) or (g) of this 
section, an operator is to be subjected to 10 open-and-close cycles of 
operation while connected to the door or doors specified in paragraphs 
(c) and (e) of this section. The cycles are not required to be 
consecutive. Motor cooling-off periods during the test meet the intent 
of the requirement. The means supplied to comply with the requirement in 
paragraph (a) of this section and Sec. 1211.8(a) are to be defeated 
during the test. An obstructing object is to be used so that the door is 
not capable of activating a lower limiting device.
    (i) During the closing cycle, the system providing compliance with 
Sec. Sec. 1211.7(a) and 1211.7(f) or 1211.7(a) and 1211.7(g) shall 
function regardless of a short- or open-circuit anywhere in any low-
voltage external wiring, any external entrapment devices, or any other 
external component.
