FF: Power Transfer?

Category: Electrified Hardware,Fixed-it FridayLori @ 12:51 am Comments (14)

Sorry I missed yesterday’s blog post!  The 7+ feet of snow that has buried us since January resulted in water coming in through my roof and out through a light fixture, so I had no electricity and no internet for a while.  🙁

Today’s Fixed-it Friday photo from an anonymous friend is a classic example of the coordination problems that can so easily arise when doors, frame, and hardware from multiple vendors arrive on the job-site.

Power Transfer Problem

In case you’re not sure what you’re looking at, it’s a frame prepared for an electric power transfer (the door is not), and a door prepped for a thru-wire hinge (the frame is not).  The purpose of these 2 products is to transfer wires from the wall and frame into the door for electrified hardware mounted on the door.

    How did they fix it?

    This is what happens when the Contractor requests frames to be ordered prior to hardware approvals.

  4. Skittlemac says:

    I dunno. But wouldn’t the simpler repair merely be to modify frame at middle hinge to accommodate an electrified hinge (with and w/o radius’d corners)? And then a filler plate for the power transfer prep at the higher location? But I’m betting that door is NOT properly fire-rated . . . so the whole thing’s a loss leader anyway…tx eh, JM.

  5. Lee Francisco says:

    Well since that door has a large scratch in it I would replace the door.

  6. Lapointe says:

    I’ll Mortise the door. With the the size of the EPT it’s not too hard to angle a hole to access electronic wires.

    For a wood guy, that scratch is easy to fix, so I think I’d adapt the frame to accept the electric hinge.(assuming the opening is not fire rated)

  9. Jack Ostergaard says:

    Some of the comments above seem to infer that electric hinges are not allowed on a rated door. Is this true? Lori?

      Hi Jack –

      You can use either the EPT or the electric hinge on a fire door assembly. In my opinion, the hole for the electric hinge could be a job-site modification (NFPA 80 isn’t 100% clear), but the other half of the prep for the power transfer could not be done in the field on a fire door without permission from the listing agency.

    If it’s not a fire rated door, that wouldn’t be a hard thing to overcome. Top drill the door leaf to the hinge prep and then prep the door for the EPT, splice the wire or replace them if needed and run it out the EPT to the frame then install a hinge and be done with it. 1-1.5 hour fix.

    Like Gabe stated earlier, the frames were probably ordered prior to the hardware approval. In theory the GC would have to buy a new door but they will hang their hat on the scratch and make the distributor provide a new one.
