Such systems shall be known as combination systems. <br>Depending upon the application, local fire alarm systems shall be permitted to include the feature of locating the point of origin of the alarm by coded alarm signals or annunciation. <br>A device or system having materials or forms different from those detailed in this standard may be examined and tested according to the intent of the standard and, if found equivalent, may be approved.
