No, the CD Cylinder Dogging option would be located in the same physical space as the Von Duprin QEL motor (see images below).
Cylinder Dogging:
QEL:
the Special Dogging (SD)option is available on some 98/99 Series models and puts a cylinder in the head of the device to mechanically hold the latch(es) retracted if there is an electrical option occupying the location of the normal Cylinder Dogging (CD) option.
Or a keyswitch on the wall could be used to engage the QEL feature to electrically dog the device. This is useful when the SD option is not available.
