(b) Sensitivity test. (1) When installed as described in § 1211.10(a)(1)–(4), a photoelectric sensor shall sense the presence of a moving object when tested according to paragraph (b)(2) of this section.

(2) The moving object is to consist of a 1% inch (47.6 mm) diameter cylindrical rod, 341⁄2 inches (876 mm) long, with the axis point being 34 inches (864 mm) from the end. The axis point is to be fixed at a point centered directly above the beam of the photoelectric sensor 36 inches (914 mm) above the floor. The photoelectric sensor is to be mounted at the highest position as recommended by the manufacturer. The rod is to be swung as a pendulum through the photoelectric sensor's beam from a position 45 degrees from

the plane of the door when in the closed position. See figure 4.

(3) The test described in paragraph (b)(2) of this section is to be conducted at three points over the width of the door opening, at distances of 1 foot (305 mm) from each end and the midpoint.

(c) Ambient light test. (1) A photoelectric sensor shall operate as specified in §1211.8 (a) and (b) when subjected to ambient light impinging at an angle of 15 to 20 degrees from the axis of the beam when tested according to paragraph (c)(2) and, if appropriate, paragraph (c)(3) of this section.

(2) To determine compliance with paragraph (c)(1) of this section, a 500 watt, 3600K Photo Floodlamp, type DXC RFL-2, is to be energized from a 120-volt, 60-hertz source.

The lamp is to be positioned 5 feet from the front of the receiver and aimed directly at the sensor at an angle of 15 to 20 degrees from the axis of the beam. See figure 5.

(3) If the photoelectric sensor uses a reflector, this test is to be repeated with the lamp aimed at the reflector.

$1211.12 Requirements for edge sen

sors.

(a) Normal operation test. (1) When installed on a representative door edge, an edge sensor shall actuate upon the application of a 15 pounds (66.7 N) or less force in the direction of the application. For an edge sensor intended to be used on a sectional door, the force is to be applied by the longitudinal edge of a 1% inch (47.6 mm) diameter cylinder placed across the switch so that the axis is perpendicular to the plane of the door. For an edge sensor intended to be used on a one piece door, the force is to be applied so that the axis is at an angle 30 degrees from the direction perpendicular to the plane of the door. See figure 6.

(2) With respect to the test of paragraph (a)(1) of this section, the test is to be repeated at various representative points of the edge sensor across the width of the door.

(3) Exception: The edge sensor need not be sensitive to actuation two inches (50.4 mm) or less from each end of the intended width of the door opening.

(b) Endurance test. An edge sensor system and associated components shall withstand 30,000 cycles of mechanical operation without failure. For

this test, the edge sensor is to be cycled by the repetitive application of the force as described in paragraph (a)(1) of this section. The force is to be applied to the same location for the entire test. For an edge sensor system employing integral electric contact strips, this test shall be conducted with the contacts connected to a load no less severe than it controls in the operator. For the last 50 cycles of operation, the sensor shall function as intended when connected to an operator.

(c) Elastomeric material conditioning test. (1) An elastomeric material used as a functional part of an edge sensor shall function as intended when subjected to:

(1) Accelerated Aging Test of Gaskets, stated in paragraph (c)(3) of this section, and

(ii) Puncture Resistance Test, stated in paragraph (d) of this section.

(2) An elastomeric material used for a functional part that is exposed to outdoor weather conditions when the door is in the closed position shall have physical properties as specified in Table 1 after being conditioned in accordance with the Ultraviolet Light Exposure Test described in the Standard for Polymeric Materials-Use in Electrical Equipment Evaluations, UL 746C, 3rd ed., dated July 1, 1991. This incorporation by reference was approved by the Director of the Federal Register in accordance with U.S.C. 552(a) and 1 CFR Part 51.
