You can use Zone Definition 16 Non-Alarm and create rules to email you or Def 14 or 14. Def 13 or 14 are 24 Hour Zones that do NOT create any alarms or keypad beeping but do LOG (no rules needed) each time the zone is tripped. If you do use Def 13 or 14 make sure under Communicator Zone RCs you set the Alarm Pulse to 00 to prevent reporting to Central Station. How long has the motion detector been installed? Has anything changed in the environment? Is the motion detector pointed towards a window, HVAC register or are there any fans, plants or curtains that could be moving. Have you taken the front cover off the motion detector to make sure no insects are inside?
