(2) To record the fact that a wire or electronic communication was initiated or completed in order to protect such provider or another provider furnishing service toward the completion of the wire communication, or a user of that service, from fraudulent, unlawful or abusive use of service; or
(3) With the consent of the user of that service.
(c) The prosecuting attorney of any county or any duly appointed special prosecutor may make application for an order or an extension of an order under this section authorizing or approving the installation and use of a pen register or a trap and trace device in writing under oath or affirmation, to the designated judge. Such application shall be made in the same manner as set forth in section ten of this article.
(d) Upon application made to the court as provided in subsections (a) and (b) of this section, the designated judge shall enter an ex parte order authorizing the installation and use of a pen register or a trap and trace device if the designated judge finds that the applicant has certified to the court that the information likely to be obtained by such installation and used is relevant to an ongoing criminal investigation.

Unless otherwise ordered by the designated judge, the results of the trap and trace device shall be furnished to the office of the law-enforcement agency, designated by the court, at reasonable intervals during regular business hours for the duration of the period during which the pen register or trap and trace device is installed as provided in such order.
