By order of the publisher, historical UL documents are not returnable for any reason. Once you place an order for an historical document, we cannot issue a refund, credit, or exchange of any kind.
These requirements apply to swinging door closers equipped with integral electromechanical or electromagnetic holders and which may be provided with integral smoke detectors. These requirements also apply to electromagnetic door holder units which are for use with a separate door closer and separate automatic fire detector.

When integral smoke detectors are provided with the combination door closer-holder, the smoke detectors shall comply with requirements for smoke detectors of the photoelectric or combustion products type.

Requirements for the installation of these combination door closer-holders with or without smoke detector units are included in the Standards of the National Fire Protection Association for Installation of Fire Doors and Windows, NFPA 80, and Automatic Fire Detectors, NFPA 72E.

The combination door closer-holders (with or without integral smoke detectors) described in this Standard provide one of the following types of hold open functions:
  1. Single point hold open.
  2. Multiple point hold open. (Two, three, four, etc. discrete hold open points as set at the manufacturer's plant.)
  3. Infinite hold open points with one as set by the user.


A product that contains features, characteristics, components, materials, or systems new or different from those in use when the Standard was developed, and that involves a risk of fire, electric shock, or injury to persons, shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to mai ntain the level of safety for the user of the product as originally anticipated by the intent of this Standard.
