Electrified Panic Devices

What Is an Electrified Panic Exit Device and When Do You Need One?

A standard panic exit device provides code-compliant egress from inside by pushing the push bar. An electrified panic exit device adds electronic control of the outside trim or the latch bolt for credential-based entry from outside. There are two electrification types. EL (Electric Latch Retraction) retracts the latch bolt electronically so the outside trim can operate the door without the latch engaging. The access control panel sends a signal to retract the latch, and the outside lever or pull operates the door.

EL (Electric Latch Retraction) vs. Electrified Trim: What Is the Difference?

EL electrification retracts the latch bolt directly from inside the exit device body. The outside lever or pull can then open the door without engaging the latch. Electrified trim applies power to the outside lever or thumbpiece to control credential-based access while the latch bolt stays engaged until the correct credential is presented. EL is used when the outside trim needs to operate in a push-pull fashion after credentials are validated. Electrified trim is used when the outside lever itself needs to be locked and released electronically.
