An activated alarm signal which is promptly followed by a call to the law enforcement or emergency services agency properly giving notice that the signal is to be disregarded shall not constitute a false alarm.
Failure of any owner or occupant to pay a fine imposed by this section within 30 days after receipt of written notice of the same shall subject such person to an additional fine of $250 for each week such violation continues.
