26、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 functions within an operator control. Devices are now being manufactured and sold thatpermit remote monitoring (to see status

27、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 WITHOUT PERMISSION FROM ULphone or other internet gateway connected devices. While some of this technology is being built into theo

28、perator 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 of these devices that may differ from traditional timer to close devices, aspecific set of requirements has been developed. Th

29、e 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 be stand-alone devices, in addition to being supplied asan integral part the operator, or may be a combination of both. The re

30、quirements 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.The requirements also clarify how, with an external accessory, compliance with the required entrapmentprotection provision of

31、 a garage door operator are to be maintained.Further, the instructions and marking requirements are outlined for these devices, when the device issupplied separate from the operator.These requirements reflect present practice.This revised CRD aligns with recent revisions to UL 325.Copyright 2014 Und
