A series of 4 consecutive scrimmage downs shall be awarded to the team that is next to put the ball in play by a snap at the beginning of each half and after a score (including try), safety, touchback or change of team possession. [S8]
A new series shall be awarded to the offense if: a. It is in legal possession (following the application of any accepted live ball penalty) of the ball beyond the middle when the ball is declared dead and it is the first time in this series that has happened. If a subsequent play or penalty brings the ball back behind the middle and the ball is then advanced across the middle line for a second time during the same series, no new first down shall be awarded.

SECTION 2. Down and Possession after a Penalty
Article 1 - Foul Before Change of Team Possession

Article 2 - Foul After Change of Team Possession
If a penalty is accepted for a foul that occurred during a down after change of team possession, the ball belongs to the team in possession when the foul occurred. The next down shall be a first down after enforcement of the penalty.
Article 3 - Penalty Declined
If a penalty is declined, the number of the next down shall be whatever it would have been if that foul had not occurred.
Article 4 - Foul Between Downs
If a foul occurs between downs, the number of the next down shall be the same as that established before the foul occurred, unless enforcement of the penalty leaves the ball beyond the middle or the penalty mandates a first down.

If offsetting fouls occur during a down, the previous down shall be repeated.
