Heavy Duty Quiet Electric Latch Retraction Surface Vertical Rod Device - (suits doors <1220mm x <2134mm) Anodized Aluminium
Quiet electric latch retraction (QEL) provides electronic control of an exit device for environments where limited operational noise is desired. The QEL option is Von Duprin’s solution of choice for hospitals, libraries, museums and theatres where ambient noise can be disruptive.
These devices always provide mechanical egress. The electrified latch retraction can be activated by an access system or building automation system to unlatch the exit device momentarily. Often the QEL is used with a credential reader and access control system to unlock the door momentarily for authorized users.
The QEL can also be configured to electronically retract the latch for an extended period of time to allow free entry. This is a convenient alternative to mechanical dogging. If manual dogging is required, the hex dogging option is available, to order specify HD-QEL. Special centre case dogging is also available for 98/99 rim and vertical systems, specify SD-QEL.
