These requirements cover electric operators for doors, draperies, gates, louvers, windows, exterior awnings and other opening and closing appliances rated 600 V or less to be employed in ordinary locations in accordance with the National Electrical Code, NFPA 70 and the Canadian Electrical Code, Part I, C22.1.
These requirements also cover complete doors, gates, and other such assemblies that include electric opening and closing appliances.
These requirements also cover accessories, such as external entrapment protection devices, for use with appliances covered by this standard.
Doors and door operators intended for exit use, as defined in The National Fire Protection Association Life Safety Code, NFPA 101, and covered by these requirements are intended for installation in accordance with the International Building Code.
These requirements do not address active fire alarm functionality, which is addressed in NFPA 80.

1. Section 34 is intended to apply only to specific products that are combination one-piece rigid doors and the operator as a designed system. Section 34 is not intended to apply to residential garage door operators that are sold separate from the door, and that may be intended to installation on a standard or common one piece door. The additional note added to Section 34 provides clarification of this intent.
2. The current edition of UL 325 only illustrates a warning placard for a vertical garage door on page 145, Figure 62.1. This proposal adds an illustration for a horizontal garage door warning placard in a new Figure.
3. UL 325, Section 63, requires certain markings (such as nameplate ratings) to be permanently marked on the product where visible after installation. While this is practical for most products covered by UL 325, for tubular drives, this becomes a challenge. In some cases, the “end cap” and/or power supply leads are visible after installation, but in some cases the end cap is not visible or is too small to reasonably accommodate a legible marking. Also, the power cord is permitted to be a detachable type, so applying the markings on to the cord would not be permissible.
To accommodate for tubular drive construction, this proposal presents an alternative for marking location for tubular drives, allowing the required markings to be on the tubular drive enclosure, which after final installation, will be covered by the driven part. This would only be permitted when the instructions contain the required information on the markings, and when a marking is provided on the end cap and/or cord to direct the installer, user, or AHJ to these additional marking information. Tubular drives are used and installed in many countries outside North America and are often governed by standards such as IEC 60335-1 and the relevant part 2 standards. For tubular drives, recent proposals for 60335-2-97 (Particular requirements for drives for shutters, awnings, blinds and similar equipment) included provisions for when required marking were not readily visible after installation (“For drives where the marking is concealed after installation, the marking of these drives shall also be provided with the instructions.” and “The markings shall also be provided with the instructions.”)
