ABH ABH-2400-US28 – Frequently Asked Questions

1) Can the ABH 2400 electromagnetic door holder be used on a labeled fire door or a smoke barrier door?
Yes. The 2400 Series magnetic holder is UL and ULC listed for use on smoke barrier doors and labeled fire doors, so it can be tied into the fire alarm and release the door on alarm. That is the whole point of the device: it holds the corridor or cross-corridor door open in normal use and drops it the instant power is cut.
2) What voltage does the ABH 2400 door holder run on, and do I have to order it for a specific one?
One part covers all three. The 2400 is tri-voltage: 12V DC, 24V AC/DC, or 120V AC. You do not pick a voltage when you order, which is why an integrator or an MRO stockroom can carry a single holder for a building with mixed 24V alarm circuits and 120V house power.
3) How far off the wall does the ABH 2400 magnet stand, and what if my door swings further than that?
Three projections are offered: 5/8 inch, 1-1/8 inch, and 1-7/8 inch. If the gap between the wall and the door in the held-open position is bigger than that, optional extension rods take it out to 2-7/8 inch, and they fill the gap without any special adapter. Measure from the finished wall face to the door face with the door held where you want it, then pick the projection that lands closest under that number.
4) What is the difference between the standard, low profile, and extreme low profile armature on the ABH 2400?
The armature is the plate that mounts on the door and meets the magnet, and it is the choice you make when ordering. The 2400 takes a standard armature, a low profile armature (the 2400L build), or an extreme low profile armature, matched to the flush wall mount 2400LS arrangement. Pick the lower profile plates where you do not want a proud disc sticking off the door face, or where the door hardware and the wall are close enough that a full standard armature would foul. All three armature types are available in every finish the holder is offered in.
5) Does the ABH 2400 magnetic door holder meet Buy American requirements for a federal or government project?
Yes, the 2400 Series is BAA qualified, which is what a government, VA, or federally funded institutional spec normally asks for on door control hardware.
6) Is the ABH 2400 a flush mount holder or does it surface mount to the wall?
Flush mount. The 2400 and 2400L set into the wall, and the 2400LS is the flush wall mount arrangement with a flush mount armature on the door. Plan for a rough-in box in the wall rather than a bracket screwed to the finished surface, and pull the installation template for the version you order before the drywall closes up.
7) Can I hold the door open manually with the ABH 2400, and will the door definitely let go when the alarm trips?
There is a release button on the holder for manual release, and it is built to kill residual magnetism so the door actually lets go rather than sticking to the magnet face. Residual hold is the classic failure on a cheap electromagnetic holder, and it is the thing a fire marshal will test for on a walkthrough.
8) Will the ABH 2400 armature line up if my door does not close perfectly flat against the magnet?
The armature pivots with 360 degree mobility, so it self-aligns to the magnet face instead of forcing you to shim the plate or chase a perfect strike. That tolerance is what makes the 2400 workable on older openings where the door has settled out of plane.
9) I need to replace an electromagnetic door holder from another manufacturer. Does ABH publish a cross reference?
Yes. ABH publishes an electromagnetic door holder cross reference covering its holders, which is the document to check when you are swapping out another brand's magnet and want the matching 2400 Series part and projection.
10) What finishes does the ABH 2400 door holder come in so I can match the rest of the hardware in the corridor?
Eight: painted aluminum, painted brass, painted bronze, painted black, painted dark bronze, satin aluminum, bright stainless steel, and satin stainless steel. Satin stainless is the usual match for a building already running 630 lever and closer hardware; painted dark bronze suits dark anodized frames.
11) Is the ABH 2400 magnetic holder made of plastic parts that will break in a busy building?
All-metal construction, no plastic components, and it is rated for commercial use. On a healthcare corridor or a school where the door gets pushed off the magnet by hand dozens of times a day, that armature and housing are the parts that take the abuse.
