PropStop utilizes the StaffAlerter SmartBoard which is a Wi-Fi-connected, ultra-low battery-powered board.  PropStop can mount to any door and is sold with a normally closed door contact switch.

Information on the door position is sent to the StaffAlerter Dashboard to display the current status.  A customizable time value is set to determine what period a door is left open before the system determines a propped open condition exists. Upon a detected door prop condition, the StaffAlerter Cloud rules engine will trigger any programmed actions to trigger local alerts including overhead pages or notify staff of the security issue.
