EPT-SC SERIES ELECTRICAL POWER TRANSFER FOR SWING CLEAR

HINGED DOOR APPLICATIONS - INSTALLATION INSTRUCTIONS

1 DESCRIPTION

The EPT-SC allows an electric lock or exit device, such as a Securitron Touch Sense Bar or Tou ch
Sense Handle, to be installed while concealing and protecting the cabling between the hinged
edge of a door and its door frame. The EPT-SC provides a flexible steel shie ld conduit which is
approximately 5/16” [7,9mm] I.D. (inside diameter). The EL-EPT-SC is furnished with a wire
harness already installed which includes ElectroLynx® connectors at each end.

The EPT-SC power transfer device has been specifically designed and configured for installation
on doors using Swing Clear type hinges.

Note: The EPT-SC will NOT work on doors utilizing center pivot type hinges.

4 INSTALLATION

For a proper EPT-SC install, all doors and frame s must utilize a flush surface mount installatio n.
If the door/frame is pre-prepped by the manufacturer, then use the pre-fabricated mounting
features and the hardware provided to install the EPT-SC as discussed in Section 4.3 or 4.4. If
the installation is a field retrofit, determine the door and frame construction, then proceed to
mark the door and frame in accordance with Section 4.1.

4.1 Vertical Placement

Because of potential structural obstacles within met al doors and frames, the EPT-SC lead covers
should be positioned a minimum of 6” [152,4mm] from the any hinge recess (as shown in
Figure 2) or centered between hinges.

Note: Due to variances in manufacturing, the door/frame manufacturer should be
consulted for specific construction and configuration information.

4.2 Marking the Door and Frame for Install

 Mark a vertical centerline for the EPT-SC lead cover at the center of the door edge. Measure

the distance from this mark to the edge of the hinge half that is attached to the door (see “X”
of “DOOR” prep. in Figure 1 or Figure 2). Use this same distance to mark from the edge of
the hinge half on the frame (see “X” of “FRAME” prep. In Figure 1 or Figure 2).

 Using the included template and the information shown in Figure 1 (for wood) or Figure 2

(for metal), align and mark the cutout positions required for the lead co vers on both the door
edge and the frame.

Note: Because of the nature of the Swing Clear hinges and the orientation of the edge
of the door in the open position, the door will most likely need to be removed after
marking to perform the preparation process for the lead cover installation.

4.3 Wood Doors and Frames:

 Using a router with a 1/4” diameter bit, cut the main recess slot into th e edge of th e door and

the frame to a depth of .700” [17,8mm] as shown in Figure 1.

Figure 1 – Wood Door/Frame Prep.

 Using a 1” [25,4mm] diameter bit with the router depth set to .075” [1,9mm], route the two

(2) recesses required for the rounded lead cover end flanges.

 One at a time, place each lead cover into its intended position and mark the two (2) mountin g

hole locations and the cable feed thru (obround) hole location for each cover.

Note: The 3/4” [19,0mm] diameter holes required for the wire feed thru in the door
and frame must be positioned at opposing ends with respect to each other. (i.e. if the
hole is toward the top of the lead cover to go in the door, then the hole for the wire
feed thru of the lead cover in the frame should be at the bottom (see Figure 1).

 Drill the (2) two mounting holes for each lead cover using a 1/ 8” [3,2mm] diameter drill bit.

Drill all four (4) holes to a depth of approximately 5/8” [15,9mm].
