The Dortronics 7286-PT series of door prop alarms provide an audible warning sounder, at the door, if it is not closed within a specified time. Upon a forced door condition or if the door has not been closed during the warning period, an alarm relay is activated and can be utilized to signal other monitoring systems. A Piezo alert is also sounded locally. The "warning" period may be set from 0 seconds to 5 minutes. During this sequence the sounder emits a beeping tone to remind the user to close the door. If the door is not closed before the end of this warning period, then the "door prop" alarm sequence is activated. At this point the alarm relay is activated and the local sounder emits a steady alarm alert. This alarm is continuous until reset.
