Door Closers

Equipment is listed if it appears in a list that is published by a
nationally recognized testing laboratory which 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 in determining if the equipment is listed. Where such

type
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 BOCA
National Building Code:
Self-Closing:
As applied to a fire panic bar alarms or other opening protective,
means normally closed and equipped with an approved device which

will
insure closing after having been opened for use.
Automatic: As applied to fire protection devices, automatic refers

to a
device or system that provides an emergency function without the

necessity
of human intervention and activated as a result of a predetermined
temperature rise, rate of temperature rise or increase in an

automatic sprinkler
system, automatic fire exit panic bar alarms push bar alarm, etc.
