Solutions by Application


The Partner Alliance for Safer Schools (PASS) recommends the use of indication trims for the classroom. Beyond the classroom, though, many spaces within a school environment can benefit from indication to enhance security. These include offices, teachers' lounges, study halls, adjoining rooms, libraries and other gathering spaces.

Educational Settings for Security & Privacy

In higher education settings, use of indication as a security measure can be widespread. But privacy applications on individual study pods, rehearsal rooms, single occupancy restrooms, and faculty offices are also valuable. In addition to standard messages, custom messaging can also be created for specialized applications.

In hospital settings applications are mostly about privacy: patient restrooms, single occupancy restrooms, lactation rooms, physician sleeping/on call rooms, and dressing rooms. Multi-stall restrooms with thicker stall doors may also benefit. And when safety is important, indication can be used on radiology or other therapy room doors as well.


Retail applications can include spaces like restaurants where patrons can see the availability of a restroom to minimize their time away from the table. Within a retail space, they can be used on dressing rooms or any room requiring temporary closures. Other applications include exterior doors such as service station restrooms or any facility with exterior entrances to private rooms.

Commercial Real Estate

Within commercial properties indication is primarily about privacy. It is useful for single occupancy restrooms and shower rooms. Where stall doors are thicker (1-3/8" minimum) it can be applied to multi-stall restrooms. Beyond that, there are uses for any meeting or focus rooms where occupancy, readily visible from outside, is desired.

Specialized Uses

Churches, factories, airports, arenas and other spaces large and small can benefit from indication use. These can include any single occupancy room requiring privacy such as a mother's lactation room or family- and assisted-use restrooms, also rooms requiring temporary closures due to cleaning or stocking.


Control access and maintain security within a facility, ensuring that only authorized individuals can enter. Additionally, Von Duprin visual indicators provide real-time information to occupants and security personnel about the status of entry points, enabling swift response to any security breaches or emergencies.

Large Assembly Areas

Von Duprin visual indicators support the safety of attendees during events or emergencies by helping organizers and security personnel quickly identify locked or unlocked doors, enabling prompt responses and enhancing overall security measures.
