Dormakaba ES105 Electric Power Transfer for ES, DE & MLR Options

The ES105 is the electric power transfer that carries wiring from the frame into a moving door leaf so an electrified exit device keeps its circuit as the door swings. It is the transfer component used with Dormakaba's ES, DE and MLR options, so if you are specifying any of those three electrified functions, the power has to get across the hinge gap and this is the part that does it. It is a commercial door hardware component, not a device on its own.

No. The Dormakaba ES105 is an electric power transfer, the component that carries wiring from the frame across to a door leaf so an electrified exit device option such as ES, DE or MLR can be powered. The Von Duprin 50602 is a lever shaft lock for 371, 373, 375 and 378 exit device trim, a mechanical part that secures the lever shaft within the trim. The 50602 carries no conductors and does nothing to get power onto a moving door, so an opening that needs an electrified exit device still needs a transfer device. The two can appear on the same door without overlapping.

Look at the Trimco LDH100 Series one-touch mechanical lockdown for exit devices. It is a mechanical lockdown accessory, so it secures the device without any wiring run to the door. The Dormakaba ES105 solves a different problem: it is an electric power transfer that gets power across the hinge side of the opening for ES, DE and MLR electrified options. If the requirement is lockdown by hand rather than a powered function, the LDH100 Series addresses it directly and the opening needs no power transfer at all.

They sit at different points in the specification. The Dormakaba ES105 is the electric power transfer that supports Dormakaba ES, DE and MLR electrified exit device options, so it belongs on a drawing wherever an exit device function is controlled electrically and conductors have to reach the door leaf. The Trimco LDH100 Series is a one-touch mechanical lockdown for exit devices, operated at the device itself. Specifying the LDH100 Series does not remove the need for a power transfer on an electrified opening, and specifying the ES105 does not provide a manual lockdown. Both are commercial door hardware components.
