QEL Electric Latch Retraction



Von Duprin QEL Electric Latch Retraction Conversion Kit 3'


The QEL feature allows for the remote unlatching of exit devices.
A control station operator can flip a switch to retract the latch
bolt and immediately change an exit door to push-pull operation.
Different than the popular EL, the QEL quiet operation is
achieved using an electric drive motor which retracts the latch
bolt either momentary unlatching or for extended periods of
time. This feature is an alternative to manual dogging.

QEL devices are also useful with automatic door operators, and
may be applied to fire-rated applications when under the control
of an automatic fire alarm system.

UL approved for Class II circuit applications.

The QEL option does not include the power transfer from door to
frame, the power supply, or the control operator. Refer to EPT-2
power transfer and the PS902 or 914 power supply.
