What is an exit device? An exit device often appears like a belt that goes across the door. Likely you’ve seen them and used them without knowing their name. They’re typically installed in busy areas or places to create an efficient exit in the case of an emergency. They can be found in hospitals, office buildings, academic settings and even the New York City subway. Exit devices are very common, but most people know very little about how important they are at serving for safe and practical purposes.
The main purpose of an exit device is to provide a safe and efficient exit from a building. To do this, the user places their hand(s) on the push bar and by doing so releases the door from its locked position. Often times the exit device is connected to an alarm system. The alarm system is in place to save time alerting those in the vicinity that a dangerous or sometimes unlawful predicament is occurring. Most exit devices also are equipped with fire and smoke utilities. This allows them to release harmful fumes or increasing temperatures in some way according to their design.

These codes protect you under law and ensure the functionality of your door in place. If you don’t have these codes, in the event of an emergency you’re looking down the barrel of a big lawsuit.

Especially if customization is involved.
