25、urement 2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the late
26、st edition of that code or standard. 3 Glossary 3.1 For the purpose of this standard the following denitions apply. 3.2 CAR DOOR OR GATE INTERLOCK A device having two related and interdependent functions, which are: a) To prevent the operation of the driving machine by the normal operating device un
27、less the car door is locked in the closed position. b) To prevent the opening of the car door from inside the car unless the car is within the landing zone and is either stopped or being stopped. 3.3 CLOSED POSITION OF CAR AND HOISTWAY DOORS AND GATES As dened in the Safety Code for Elevators and Es
28、calators, ASME A17.1: a) Horizontally sliding hoistway doors and gates (ASME A17.1, Clause 2.12.2.2); b) Horizontally sliding car doors and gates (ASME A17.1, Clause 2.14.4.11); and c) Vertically sliding counterweighted and counterbalanced hoistway doors (ASME A17.1, Clause 2.12.3.2). 3.4 DOOR OR GA
29、TE ELECTRIC CONTACT An electrical device, the function of which is to prevent operation of the driving machine by the normal operating device unless the door or gate is in the closed position. 3.5 HOISTWAY DOOR COMBINATION MECHANICAL LOCK AND ELECTRIC CONTACT A combination mechanical and electric de
30、vice with two related, but entirely independent, functions, that are: a) To prevent operation of the driving machine by the normal operating device unless the hoistway door is in the closed position and b) To lock the hoistway door in the closed position and prevent it from being opened from the lan
31、ding side unless the car is within the landing zone. As there is no positive mechanical connection between the electric contact and the door locking mechanism, this device ensures only that the door will be closed, but not necessarily locked, when the car leaves the landing. Should the lock mechanis
32、m fail to operate as intended when released by a stationary or retiring car-cam device, the door can be opened from the landing side even though the car is not at the landing. If operated by a stationary car-cam device, it does not prevent opening the door from the landing side as the car passes the

34、t the operation of the driving machine by the normal operating device unless the hoistway door is locked in the closed position and b) To prevent the opening of the hoistway door from the landing side unless the car is within the landing zone and is either stopped or being stopped. 4 Operation 4.1 H
35、oistway-door interlocks 4.1.1 An interlock contact shall be positively opened by the locking member or by a member connected to and mechanically operated by the locking member. 4.1.2 An interlock contact shall be maintained in the open position by the action of gravity or by a restrained compression
36、 spring, or by both, or by means of the opening member. 4.1.3 An interlock shall hold the door in the locked position by means of gravity or by a restrained compression spring, or by both, or by means of a positive linkage. 4.1.4 An interlock shall lock the door in the closed position before the int
37、erlock contacts close. 4.1.5 The requirements of 4.1.1 4.1.4 do not apply to interlocks used that are marked for use only in dumbwaiters, material lifts, or private residence elevators. 4.2 Hoistway-door combination mechanical locks and electric contacts 4.2.1 A hoistway-door combination mechanical
38、lock and electric contact shall be designed so that the locking member and the electric contact are mounted on and attached to a common base in such a manner that there is a xed relation between the location of the contact and the location of the locking member. They shall be designed so that when i
39、nstalled and adjusted in accordance with the manufacturers instructions: a) The electric contact cannot close until the door is in the closed position and b) The locking member is in a position to lock the door when or before the contact closes. In order to prevent motion of the door from opening th
40、e electric contact while the door is locked in the closed position, multiple-locking points shall, where necessary, be provided on the locking mechanism. 4.2.2 The electric contact shall be positively opened by the locking bar of the mechanical lock or by a lever or other device attached to and oper
41、ated by the door. The contact shall be maintained in the open position by the action of gravity, a restrained compression spring, both, or by positive mechanical means.

43、positively opened by a lever or other device attached to and operated by the car door or gate. 4.3.2 Hoistway-door, car-door and gate electric contacts shall be maintained in the open position by the action of gravity, or a restrained compression spring, both, or by positive mechanical means. CONSTR
44、UCTION 5 Assembly 5.1 A hoistway-door, car-door, or gate-locking device or contact shall have the strength and rigidity necessary to resist the abuses to which it may be subjected without resulting in a risk of re, electric shock, or injury to persons due to total or partial collapse with resulting
45、interference with the functioning of parts, loosening or displacement of parts, or reduction of spacings. 6 Enclosure 6.1 The enclosure shall be constructed and assembled so that it will withstand handling during shipment and installation. 6.2 The enclosure and parts, such as covers, shall be provid
46、ed with means for rmly securing them in place. 6.3 Bolts, screws, or other parts used for mounting the device shall be independent of those used for securing parts of the device to the frame, base, or enclosure. 6.4 A sheet metal enclosure shall not be less than 0.053 inch (1.35 mm) thick. 6.5 A cas
47、t metal enclosure, whether iron or other metal, shall be at least 1/8 inch (3.2 mm) thick at all points and of greater thickness at reinforcing ribs and door edges, and not less than 1/4 inch (6.4 mm) thick at tapped holes for conduit. 6.6 The mechanical strength of a nonmetallic enclosure shall be
48、at least equivalent to a sheet metal enclosure of the minimum thickness specied in 6.4. 6.7 Among the factors taken into consideration when evaluating the acceptability of a nonmetallic enclosure are: a) The mechanical strength; b) Resistance to impact; c) Moisture-absorption properties; d) Combusti
49、bility and resistance to ignition from electrical sources; e) Dielectric strength, insulation resistance, and resistance to arc tracking; and FEBRUARY 26, 2016 ELEVATOR DOOR LOCKING DEVICES AND CONTACTS - UL 104 8UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL f) Resistance to distortion and creeping at temperatures to which the material may be subjected under conditions of normal or abnormal usage.
