                         Subpart A--The Standard
 
Sec. 1211.11  Requirements for photoelectric sensors.

    (a) Normal operation test. (1) When installed as described in 
Sec. 1211.10(a) (1)-(4), a photoelectric sensor shall sense an 
obstruction as described in paragraph (a)(2) of this section that is to 
be placed on the floor at three points over the width of the door 
opening, at distances of 1 foot (305 mm) from each end and the midpoint.
    (2) The obstruction noted in paragraph (a)(1) of this section shall 
consist of a white vertical surface 6 inches (152 mm) high by 12 inches 
(305 mm) long. The obstruction is to be centered under the door 
perpendicular to the plane of the door when in the closed position. See 
figure 3.

    (b) Sensitivity test. (1) When installed as described in 
Sec. 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\7/8\ inch (47.6 mm) 
diameter cylindrical rod, 34\1/2\ 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 Sec. 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.
