Overview

Designed for high use and abuse institutional environments, such as K-12 and higher educational campuses, the Von Duprin security indicators are recommended for the following applications: visual verification and lockdown. The visual verification application reduces the time to tour a facility and ensure that each door is secure with at-a-glance visual verification. The security indicators provide visual verification from inside the room and are ideal for high occupancy areas like auditoriums, cafeterias and gymnasiums.

The -2SI security indicator provides at-a-glance verification of the “LOCKED” and “UNLOCKED” door status from the inside of the room. Also available without security indicator, as -2. These options can be ordered as a new product or as a retrofit conversion kit for existing 98/99 Series exit devices.
