Modular QEL Conversion Kit
• Recommended conversion kit solution for most applications
• Greater inventory flexibility: Can upgrade both 3’ and 4’ devices
• Ease of installation: Can easily and quickly be installed in existing product
• Lower list price: Same functionality offered at
a lower list price

The Quiet Electric Latch (QEL) retraction latch option for Von Duprin® exit
devices provides electronic control of an exit device for environments where
limited operational noise is desired.
This optional feature is offered in fully configured exit devices, or as a
conversion kit to mechanical or legacy latch retraction devices currently
installed, to enhance the opening’s operability.
Von Duprin offers both a modular and baseplate QEL conversion kits.
In most applications, the modular QEL kit provides the necessary
functionality at the lowest cost and is the recommended solution. The
modular QEL conversion kit should be selected unless the product is
currently a solenoid-driven latch retraction device (EL).
The baseplate QEL conversion kit was the initial conversion kit offered
when Von Duprin originally launched the QEL. With the improved design of
the motor assembly and availability of the modular conversion kit, the
baseplate QEL conversion kit should primarily be used when converting
an EL to a motor driven QEL solution.
The modular conversion kit was developed to improve the flexibility, cost,
and installation process without the requirement of replacing the entire
baseplate assembly. The modular motor assembly provides the same
functionality and fits in both 3’ device and 4’ device. This design allows for
flexibility of inventory and solutions for a broader set of openings.
