(a) The reopening device(s) shall be permitted to be rendered inoperative
(2) for detection of approaching objects
(-b) when 20 s have transpired after the detection means of approaching objects first detects an object. When an object is detected in the path of the doors, the 20 s duration shall reset.
(b) Where Phase I Emergency Recall Operation by a fire alarm initiating device (see 220.127.116.11) is not provided, door reopening devices that can be affected by smoke or flame shall be rendered inoperative after the doors have been held open for 20 s after a door close signal has been initiated. Door closing for power-operated doors shall conform to 2.13.4.
(c) When the reopening device(s) has been rendered inoperative per (a)(1), a continuously sounding audible signal shall be provided with a sound level of 10 dBA minimum above ambient and shall not exceed 80 dBA. The sound level shall be measured 1 m (40 in.) above the landing floor, 500 mm (20 in.) from the door face, along the centerline of the entrance opening, with the doors open. The signal shall sound during door closing until the doors are fully closed. In no case shall the sound level exceed 85 dBA inside the cab and within 300 mm (12 in.) from the centerline of the entrance and 1 m (40 in.) above the floor.
(a) diameter of 200 mm (8 in.), height of 1000 mm (40 in.), and painted flat black per FED-STD-595C in the color range from 37005 through 37050
(b) diameter of 200 mm (8 in.), height of 1000 mm (40 in.), and painted glossy white per FED-STD-595C in the color range from 17800 through 17999
NOTE (18.104.22.168): See Nonmandatory Appendix S, Figure S-13.
The approaching object detection means shall be effective until the leading edge of the doors is within 450 mm (18 in.) of the fully closed position and shall be permitted to be effective up to the fully closed position.
(a) 80 mm (3.15 in.) by 50 mm (2 in.) by 150 mm (6 in.), painted flat black per FED-STD-595C in the color range from 37005 through 37050
(b) 80 mm (3.15 in.) by 50 mm (2 in.) by 150 mm (6 in.), painted glossy white per FED-STD-595C in the color range from 17800 through 17999
NOTE (22.214.171.124): See Nonmandatory Appendix S, Figures S-14 and S-15.
(b) centered between the two vertical planes described in (a) if the distance between the two planes is less than 150 mm (6 in.)
(b) centered between the two planes if the distance between the two planes is less than 150 mm (6 in.]
