CONSUMER PRODUCT SAFETY COMMISSION

16 CFR Part 1211

 
Safety Standard for Automatic Residential Garage Door Operators

AGENCY: Consumer Product Safety Commission.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Consumer Product Safety Commission is amending regulations 
on the Safety Standard for Automatic Residential Garage Door Operators, 
to reflect changes made by Underwriters Laboratories, Inc. in its 
standard UL 325.

DATES: The rule will become effective on December 27, 2000. The 
incorporation by reference of certain publications in this rule is 
approved by the Director of the Federal Register as of December 27, 
2000.

FOR FURTHER INFORMATION CONTACT: Renae Rauchschwalbe, Office of 
Compliance, Consumer Product Safety Commission, Washington, DC 20207, 
telephone 301-504-0608, ext. 1362.

SUPPLEMENTARY INFORMATION: The Commission issued part 1211 on December 
21, 1992 to minimize the risk of entrapment by residential garage door 
openers. As mandated by section 203 of Public Law 101-608, subpart A of 
part 1211 codifies garage door operator entrapment provisions of 
Underwriter Laboratories, Inc. (``UL'') standard UL 325, third edition, 
``Door, Drapery, Louver and Window Operators and Systems.'' 
Subparagraph (c) of section 203 of Pub. L. 101-608 also required the 
Commission to incorporate into part 1211 any revisions that UL proposed 
to the entrapment protection requirements of UL 325, unless the 
Commission notified UL that the revision does not carry out the 
purposes of Pub. L. 101-608.
    UL proposed revisions to UL 325 on June 30, 1998, and made them 
final on September 18, 1998. The Commission determined that the 
entrapment related revisions do carry out the purposes of Public Law 
101-608. On June 14, 2000, the Commission proposed a rule incorporating 
into subpart A of part 1211 those revisions that relate to entrapment 
by residential automatic garage door operators and also correcting a 
few typographical errors in part 1211. 65 FR 37318. The Commission 
received one comment on the proposed rule from six students at Florida 
International University. Their comment discussed generally the 
entrapment hazard posed by garage doors and precautions that garage 
door owners should take. They suggested a mandatory standard requiring 
both an external entrapment-sensing safety device and a constant 
contact control button. However, this would mean that the consumer 
would have to stand in the garage at the button until the door is 
completely closed. Aside from the inconvenience of such a requirement, 
it is beyond the scope of this rulemaking, the narrow purpose of which 
is to revise the existing Commission standard to reflect recent changes 
to UL 325.
    The changes to the UL standard allow for advances in the state of 
the art in garage door safety. Some new garage door operators have an 
inherent entrapment protection system that can continuously monitor the 
position of the door. The UL revisions add requirements for this type 
of system. Some new garage door operators have an inherent secondary 
door sensor that is independent of the primary entrapment protection 
system. The UL revisions add requirements for this type of new system. 
Finally, the UL standard adds some new and revised provisions 
concerning instructions and field installed labels. The final rule 
incorporates these changes into the CPSC mandatory standard.
    Pursuant to section 605(b) of the Regulatory Flexibility Act, 5 
U.S.C. 605(b), the Commission certifies that this rule will not have a 
significant impact on a substantial number of small entities. Most of 
the changes are editorial and minor. The substantive changes only 
affect the few companies that are developing the new type of garage 
door operators discussed above. Moreover, UL has already made these 
changes to its UL 325 standard which is widely followed by the 
industry. The Commission also certifies that this rule will have no 
environmental impact. The Commission's regulations state that safety 
standards for products normally have little or no potential for 
affecting the human environment. 16 CFR 1021.5(c)(1). Nothing in this 
rule alters that expectation.
    Public Law 101-608 contains a preemption provision. It states: 
``those provisions of laws of States or political subdivisions which 
relate to the labeling of automatic residential garage door openers and 
those provisions which do not provide at least the equivalent degree of 
protection from the risk of injury associated with automatic 
residential garage door openers as the consumer product safety rule'' 
are subject to preemption under 15 U.S.C. 2075. Pub. L. 101-608, 
section 203(f).
    The rule will become effective 30 days from publication in the 
Federal Register and will apply to garage door operators entering the 
chain of distribution on or after that date. The 30-day effective date 
is appropriate because the substantive changes affect only a few 
companies and they are identical to changes already made to UL 325, 
which is widely followed by the industry.

paragraph (a)(9) to read as follows:


Sec. 1211.5  General testing parameters.

    (a) * * *
    (1) With regard to electrical supervision of critical components, 
an operator being inoperative with respect to downward movement of the 
door meets the criteria for trouble indication.
* * * * *
    (6) When a Computational Investigation is conducted, 
p shall not be greater than 6 failures/10\6\ hours 
for the entire system. For external secondary entrapment protection 
devices that are sold separately, p shall not be 
greater than 0 failures/10\6\ hours. For internal secondary entrapment 
protection devices whether or not they are sold separately, 
p shall not be greater than 0 failures/10\6\ hours. 
The operational test is conducted for 14 days. An external secondary 
entrapment protection device that is sold separately, and that has a 
p greater than 0 failures/10\6\ hours meets the 
intent of the requirement when for the combination of the operator and 
the specified external secondary entrapment protection device 
p does not exceed 6 failures/10\6\ hours. See 
Sec. 1211.15(i) and (k).
    (7) When the Demonstrated Method Test is conducted, the multiplier 
is to be based on the continuous usage level, and a minimum of 24 units 
for a minimum of 24 hours per unit are to be tested.
    (8) * * *
    (9) For the Electrical Fast Transient Burst Test, test level 3 is 
to be used for residential garage door operators.
* * * * *


Sec. 1211.6  [Amended]

    6. Section 1211.6 is amended by revising paragraphs (a), (b) 
introductory text, (b)(1)(ii), (b)(1)(iii), (b)(2), adding a new 
paragraph (b)(3), revising paragraphs (c) and (d), and removing 
paragraph (e) to read as follows:


Sec. 1211.6  General entrapment protection requirements.

    (a) A residential garage door operator system shall be provided 
with primary inherent entrapment protection that complies with the 
requirements as specified in Sec. 1211.7.
    (b) In addition to the primary inherent entrapment protection as 
required by paragraph (a) of this section, a residential garage door 
operator shall comply with one of the following:
    (1) * * *
    (i) * * *
    (ii) Reverse direction and open the door to the upmost position 
when constant pressure on a control is removed prior to operator 
reaching its lower limit, and
    (iii) Limit a portable transmitter, when supplied, to function only 
to cause the operator to open the door;
    (2) Shall be provided with a means for connection of an external 
secondary entrapment protection device as described in Secs. 1211.8, 
1211.10, and 1211.11; or
    (3) Shall be provided with an inherent secondary entrapment 
protection device as described in Secs. 1211.8, 1211.10, and 1211.12.
    (c) A mechanical switch or a relay used in an entrapment protection 
circuit of an operator shall withstand 100,000 cycles of operation 
controlling a load no less severe (voltage, current, power factor, 
inrush and similar ratings) than it controls in the operator, and shall 
function normally upon completion of the test.
    (d) In the event malfunction of a switch or relay (open or short) 
described in paragraph (c) of this section results in loss of any 
entrapment protection required by Secs. 1211.7(a), 1211.7(f), or 
1211.8(a), the door operator shall become inoperative at the end of the 
opening or closing operation, the door operator shall move the door to, 
and stay within, 1 foot (305 mm) of the uppermost position.
    7. Revise Section Sec. 1211.7 to read as follows:


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

[[Page 70658]]

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. 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 
Secs. 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.

    8. Section 1211.8 is revised to read as follows:


Sec. 1211.8  Secondary entrapment protection requirements.

    (a) A secondary entrapment protection device supplied with, or as 
an accessory to, an operator shall consist of:
    (1) An external photoelectric sensor that when activated results in 
an operator that is closing a door to reverse direction of the door and 
the sensor prevents an operator from closing an open door,
    (2) An external edge sensor installed on the edge of the door that, 
when activated results in an operator that is closing a door to reverse 
direction of the door and the sensor prevents an operator from closing 
an open door,
    (3) An inherent door sensor independent of the system used to 
comply with Sec. 1211.7 that, when activated, results in an operator 
that is closing a door to reverse direction of the door and the sensor 
prevents an operator from closing an open door, or
    (4) Any other external or internal device that provides entrapment 
protection equivalent to paragraphs (a)(1), (a)(2), or (a)(3) of this 
section.
    (b) With respect to paragraph (a) of this section, the operator 
shall monitor for the presence and correct operation of the device, 
including the wiring to it, at least once during each close cycle. In 
the event the device is not present or a fault condition occurs which 
precludes the sensing of an obstruction, including an open or short 
circuit in the wiring that connects an external entrapment protection 
device to the operator and device's supply source, the operator shall 
be constructed such that:
    (1) A closing door shall open and an open door shall not close more 
than 1 foot (305 mm) below the upmost position, or
    (2) The operator shall function as required by Sec. 1211.6(b)(1).
    (c) An external entrapment protection device shall comply with the 
applicable requirements in Secs. 1211.10, 1211.11 and 1211.12.
    (d) An inherent secondary entrapment protection device shall comply 
with the applicable requirements in Sec. 1211.13. Software used in an 
inherent entrapment protection device shall comply with the Standard 
for Safety for Software in Programmable Components, UL 1998, Second 
Edition, May 29, 1998. This incorporation by reference was approved by 
the Director of the Federal Register in accordance with 5 U.S.C. 552(a) 
and 1 CFR part 51. Copies may be obtained from Global Engineering

Sec. 1211.9  [Amended]

    9. Section 1211.9 is amended by revising paragraph (a), 
redesignating paragraphs (b) and (c) as paragraphs (c) and (d) 
respectively, and adding a new paragraph (b) to read as follows:

[[Page 70659]]

Sec. 1211.9  Additional entrapment protection.

    (a) A means to manually detach the door operator from the door 
shall be supplied. The gripping surface (handle) shall be colored red 
and shall be easily distinguishable from the rest of the operator. It 
shall be capable of being adjusted to a height of 6 feet (1.8 m) above 
the garage floor when the operator is installed according to the 
instructions specified in Sec. 1211.14(a)(2). The means shall be 
constructed so that a hand firmly gripping it and applying a maximum of 
50 pounds (223 N) of force shall detach the operator with the door 
obstructed in the down position. The obstructing object, as described 
in Sec. 1211.7(b), is to be located in several different positions. A 
marking with instructions for detaching the operator shall be provided 
as required by Sec. 1211.15(i).
    (b) A means to manually detach the door operator from the door is 
not required for a door operator that is not directly attached to the 
door and that controls movement of the door so that:
    (1) The door is capable of being moved open from any position other 
than the last (closing) 2 inches (50.8 mm) of travel, and
    (2) The door is capable of being moved to the 2-inch point from any 
position between closed and the 2-inch point.

Secs. 1211.13-1211.16  [Redesignated as Secs. 1211.14-1211.17]

    12. Redesignate Secs. 1211.13 through 1211.16 as Secs. 1211.14 
through 1211.17, respectively, and add a new Sec. 1211.13 to read as 
follows:


Sec. 1211.13  Inherent force activated secondary door sensors.

    (a) Normal operation test. (1) A force activated door sensor of a 
door system installed according to the installation instructions shall 
actuate when the door applies a 15 pound (66.7 N) or less force in the 
down or closing direction and when the door applies a 25 pound (111.2 
N) or less force in the up or opening direction. For a force activated 
door sensor intended to be used in an operator intended for use only on 
a sectional door, the force is to be applied by the door against the 
longitudinal edge of a 1\7/8\ (47.6 mm) diameter cylinder placed across 
the door so that the axis is perpendicular to the plane of the door. 
See Figure 6 of this part. The weight of the door is to be equal to the 
maximum weight rating of the operator.
    (2) The test described in paragraph (a)(1) of this section is to be 
repeated and measurements made at various representative points across 
the width and height of the door. For this test, a door sensor system 
and associated components shall withstand a total of 9 cycles of 
mechanical operation without failure with the force applied as follows:
    (i) At the center at points one, three, and five feet from the 
floor,
    (ii) Within 1 foot of the end of the door, at points one, three, 
and five feet from the floor,
    (iii) Within 1 foot of the other end of the door at points one, 
three, and five feet from the floor.
    (3) The cycles are not required to be consecutive. Continuous 
operation of the motor without cooling is not required.
    (b) Adjustment of door weight. (1) With the door at the point and 
at the weight determined by the tests of paragraphs (a)(2) and (b)(2) 
of this section to be the most severe, the door sensor and associated 
components shall withstand 50 cycles of operation without failure.
    (2) At the point determined by the test in paragraphs (a)(1) and 
(a)(2) of this section to be the most severe, weight is to be added to 
the door in 5.0 pound (2.26 Kg) increments and the test repeated until 
a total of 15.0 pounds (66.72 N) has been added to the door. Before 
performing each test cycle, the door is to be cycled 2 times to update 
the profile. Similarly, starting from normal weight plus 15.0 pounds, 
the test is to be repeated by subtracting weight in 5.0 pound
