Can you add hex dogging or cylinder dogging to a Von Duprin EL or QEL device?
First, please note only panic devices may have hex dogging or cylinder dogging.
HEX DOGGING
HD-QEL: Any QEL motor can be replaced with a Hex Dogging-QEL motor assembly. The part number is 958002.
HD-EL: While there is a Hex Dogging-EL conversion baseplate assembly available, this hex dogging feature is only designed for short term or occasional use.
CYLINDER DOGGING
SD-QEL, SD-EL:
The EL/QEL98/99 series rim and vertical rod and vertical cable devices can have cylinder dogging added to the device. This is done by changing to SD (special dogging) in the center case of the EL/QEL panic devices. The center case, center case cover, and SD cylinder dog housing are required and are listed in the parts price book. SD requires a 1 1/4" mortise cylinder with inverted straight cam.
The EL/QEL98/99 series mortise lock devices cannot have SD.
The EL/QEL33/35 series devices cannot have SD.
Keyswitch Option with QEL/EL: Keep in mind that the QEL/EL device may be electronically dogged for extended periods of time. A keyswitch can be added near the opening if the building owner desires "at-the-door" key-controlled dogging.
