Question: N.J.A.C. 5:70-4.11(1)2 refers to “listed closing devices.” How do you determine if a closing device is listed? Also, what is the difference between a “self-closing” and an “automatic closing device”?
Answer: Equipment is “listed” if it appears in a list that is published by a nationally recognized testing laboratory that makes periodic inspections of the production of such equipment and which states that such equipment meets nationally recognized standards or has been tested and found safe for use in a specified manner.
Often, listed equipment is “labeled” with a plate, tag, or other device that is permanently and
prominently affixed to the equipment, indicating that it has been tested and evaluated by a recognized agency. This labeling provides a way to determine if the equipment is listed. Where such labeling is not found on a closing device, the owner shall provide documentation verifying that the device is listed.
The difference between a “self-closing” and a “automatic closing device” can be explained by
utilizing the following definitions taken from the ICC International Building Code:
- Self-Closing: As applied to a fire door or other opening protective, it usually means closed and equipped with an approved device that will ensure closing after being opened for use.
- Automatic: As applied to fire protection devices, automatically refers to a device or system that provides an emergency function without the necessity of human intervention and is activated as a result of a predetermined temperature rise, rate of temperature rise, or increase in an automatic sprinkler system, automatic fire door, etc.
Question: N.J.A.C. 5:70-4.11(1)3, refers to “approved door closers”. What is considered an approved door closer? Will a list of such devices be issued?
Answer: An approved door closer is acceptable to the authority having jurisdiction. When performing fire-safety-related inspections, you must determine if the installed device is
acceptable.
According to the Division of Fire Safety, a device that will easily close an opened door without
applying additional manual force is acceptable. Additional items to be considered when determining acceptability are whether the closer device is of a type that will not require above-normal maintenance to function correctly at all times, and that the closer device effectuates positive latching of the required door lockset hardware to maintain dwelling unit security per N.J.A.C. 5:10-19.2(a)4 requirements.
The Division of Fire Safety will not publish a list of approved door closers. Therefore,
consideration of the above-mentioned performance criteria is necessary when determining
acceptability of the door closer.
If building owners should seek assistance from you to select an approved door closer device, instruct them to contact their local construction official for such information.
