On the opening cycle,activation of a user door control shall stop the door but not reverse it.32.5A.
14、5 Entrapment protection32.5A.5.1 The control accessory shall not interfere with, override, or alter any entrapment protectionfeatures of the operator or system per 32.2 and 32.3.A control accessory that only provides a momentary signal (wired or wireless) to start the door isconsidered to comply wit
15、h this requirement.32.5A.5.2 If an unattended door travelling in the closing direction is stopped and reversed by anentrapment protection device, the control accessory alone or in combination with the operator system shallbe permitted one additional unattended operation attempt to close the door.32.
16、5A.5.3 After two attempts per 32.5A.5.2, the control accessory alone or in combination with theoperator system shall suspend unattended operation. The control accessory alone or in combination withthe operator system shall require a renewed, intended input, via door control, prior to re-enablingunat
17、tended operation.32.5A.5.4 A control accessory shall only be used with an operator when the combination of the operatorand the control accessory comply with the applicable entrapment protection features including:a) Inherent Primary Entrapment Protection, in accordance with 32.2;b) Secondary Entrapm

25、 unattended operation of the door.The first types of these devices were timer-to-close functions, and requirements to address unattendedoperation were added to UL 325 in Section 32.5Since that time, these devices have evolved and technology expanded such that the devices are no longertimer-to-close
26、functions within an operator control. Devices are now being manufactured and sold thatpermit remote monitoring (to see status of door) as well as unattended activation of the door via smartSTANDARD NUMBER: UL 325 -3-UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHO
27、UT PERMISSION FROM ULphone or other internet gateway connected devices. While some of this technology is being built into theoperator control directly, some of this technology is packaged and intended to be installed in the field asan accessory to an existing operator.To address the unique features
28、of these devices that may differ from traditional timer to close devices, aspecific set of requirements has been developed. The requirements are written as a new section 32.5A,but the base requirements from existing section 32.5 were used as reference.The requirements clarify that these devices may
29、be stand-alone devices, in addition to being supplied asan integral part the operator, or may be a combination of both. The requirements address the visual andaudible alarms which are already required by UL 325 for unattended operation, and clarify the conditionunder which these need to be monitored
30、.The requirements also clarify how, with an external accessory, compliance with the required entrapmentprotection provision of a garage door operator are to be demonstrated.Further, the instructions and marking requirements are outlined for these devices, when the device issupplied separate from the
31、 operator.These requirements reflect present practice.Copyright 2014 Underwriters Laboratories Inc.UL, in performing its functions in accordance with its objectives, does not guarantee or warrant thecorrectness of Certification Requirement Decisions it may issue or that they will be recognized or ad
