Does Von Duprin offer a classroom security option with visual status indication?

Von Duprin offers two options:
 
The CDSI/HDSI Dogging Indicator provides an at-a-glance verification of the status of the door from inside of the room. Visible “LOCKED” and “UNLOCKED” indicators show whether the device is undogged or dogged.  This feature can be used with Hex key (HDSI) or Cylinder dogging (CDSI) options on various device types – rim, mortise and vertical systems. 
 
The -2SI Security Indicator provides an at-a-glance verification of the locked /unlocked status of the door from inside of the room. This option can be ordered as a new product or as a retrofit conversion kit to an existing 98/99 rim device. Indicator in “unlocked ” state presents a 1/2” x 1/2” metal flag (unlock icon, laser cut into flag) at top of device head. Indicator in “locked ” state has no flag present.
