Mercury Board Holder for Non-Standoff Installs
Print Profile(1)
Description
This is a standoff replacement for Lenel, RS2, Avigilon, or other mercury access control full-size boards (LNL-1302, LNL-2220, LNL-4420, MR52, EP-1502, LP-1502, etc)
You print the holder, and M3 heatset inserts are used to provide threaded holes for the board itself. There are six holes in the board holder that allow mounting to surfaces.
Note: Mounting the board in this way may require you to ground the board manually, as you won't have a metal path from the board being mounted. This, in some circumstances, is an advantage, as this board holder should insulate the board from the surface behind it.
Originally, I made this as a way to have the board sitting on my desk to bench test things without worrying about the rear contacts touching metal on my desk, but I added screw holes to make it dual-purpose, allowing for installation of these boards in environments where standoff-installed cans are not available.
You will need:
- (x8) 6mm long M3 brass heatset inserts
- A soldering iron to melt in the heatset inserts
- (x8) 5mm socket head M3 bolts (though you may not need all 8)
- Up to 6 standard screws (drywall, metal, self-tapping, etc) if you intend to mount the board to a flat surface
Print at 100% infill, no supports needed.
