Overview

The QEL provides electronic control of an exit device where limited operational noise is desired. It is Von Duprin’s choice solution for hospitals, libraries, museums, theaters and any other place where ambient noise is possibly disruptive. 

The QEL can retract a latchbolt momentarily or on an extended, scheduled basis via access control system. This option is available to be configured on Von Duprin 98/99, 94/95, 33A/35A, and 22 Series panic and fire-rated exit devices; or it can be ordered as a modular kit to retrofit existing devices.
