A Quick Guide to Von Duprin QEL Quiet Electric Latch Retraction Panic Bars


Von Duprin is a top brand for exit devices, which can be used in many locations like offices, schools, and hospitals. The brand stands out because they put a lot of thought into making their devices as safe as possible. One thing Von Duprin adds to their devices is an Electric Latch Retraction (ELR).

These exit devices are the best that Von Duprin can produce with the current technology. This quick guide explains what Von Duprin exit devices are, their types, and where people usually use them.

What Are Exit Devices?

Exit devices, also known as panic devices, panic bolts, or crash bars, are added to doors. They’re made to help people get out of a building quickly and easily during an emergency. An exit device can keep a door locked from the outside but can be easily opened from the inside.

This feature stops people from entering without permission while making sure everyone inside can get out fast. This could be especially important during emergencies. Sometimes, rules may require exit device installations. But most often, you find these devices in commercial buildings to boost safety and security.

Electric Latch Retraction (ELR) is an important part of exit devices. It works with systems that control access and door movement. EL/QEL, in contrast to motorized latch retraction, offers electronic control of an exit device in situations where minimal operational noise is an advantage. This feature makes a door open or unlock with a single push or pull on the latch. ELR devices are known for working silently, not needing a lot of power, and fitting well with most exit devices.

Why Should You Use Exit Devices?

Exit devices are crucial in commercial buildings and they offer many important advantages:

  • Security: You can install exit devices on some doors to stop unwanted access from the public or unauthorized individuals from within an organization. Only people with permission can unlock these doors from the outside. Considering the rise in security risks, it’s very important to keep your assets, employees, and clients safe against unwelcome entries.
  • Safety: In case of emergencies like fires or natural calamities, when people need to quickly leave a building, they can press the crash bar on the inside of the door to open it. That’s why some call it a “panic bar”. Because these devices are easy to use, even people with limited mobility or children can operate them.
  • Ease of Operation: Exit devices are made to be easy to use. You don’t need special knowledge or physical strength to operate them. This is really important in situations where people need to get out quickly and safely.
  • Compliance with Rules: Installing exit devices can help your building comply with building and safety rules set up by the government or other authorities. Being compliant will not only help you avoid legal problems but could also help cut down on insurance fees in some instances. 
  • Durability: Exit devices are built to last and can handle repeated use. They are a cost-saving and dependable option for doors that get a lot of traffic in commercial properties.
  • Reduced Liability: Exit devices can protect businesses from legal issues in emergencies. If emergency exits can’t be accessed easily, businesses could face stiff legal action or penalties. It could also damage their reputation.
  • Aesthetic Appeal: Exit devices come in various styles, finishes, and designs. This gives businesses the chance to keep their properties safe while also looking attractive.
