ABH ABH-2400LR-US28 – Frequently Asked Questions

1) Will an ABH 2400LR door holder work if my wall isn't perfectly plumb with the door?
That's what the adjustable armature is for. The 2400LR ships with a 1-1/2 inch door armature that has 3 degrees of built-in adjustment, so the armature face can be squared to the magnet even when the wall or the door hangs slightly out of true. Out-of-true walls are the usual reason an electromagnetic holder drops a door early, and the adjustment is set at install rather than shimmed.
2) What do I do if the gap between the wall and the open door is too big for the magnet to reach?
Six 1/4 inch ring extensions come in the box with the 2400LR. They stack behind the armature to close the reach on openings where the door doesn't swing back flush to the wall unit, so you can build out the distance in 1/4 inch increments without ordering a separate extension kit.
3) Is the ABH 2400LR safe for a behavioral health or detention unit?
Both halves are built for it. The wall cover and the door armature are sloped so nothing can be tied or looped around them, which is the anti-ligature detail specifiers look for in psychiatric, detention, and holding areas. It's a commercial-rated device, not a residential one.
4) Does the ABH 2400LR meet Buy American requirements for a federal job?
Yes, the 2400LR is BAA qualified, so it can go on government and institutional work carrying Buy American Act domestic sourcing language. That is usually the first thing that eliminates a door holder from a federal or municipal submittal.
5) How does an electromagnetic door holder like the 2400LR release the door in a fire alarm?
It holds by electromagnet, so it holds only while it is powered. The 2400LR is an electronic device wired to the building's fire alarm or detection circuit; when that circuit drops power, the magnet lets go and the door closer takes the door to the closed and latched position. That's the difference from a mechanical floor or wall stop, which holds a door open with no way to release it on alarm. You still need a closer on the door for the release to accomplish anything.
6) How far does the ABH 2400LR wall unit stick out into the corridor?
The wall cover projects 9/32 of an inch. That is a wall-mounted holder, so in a tight corridor or a path of travel where anything protruding is a problem, the profile stays under the 4 inch limit that governs wall projections in accessible routes by a wide margin.
7) Is the 2400LR a wall-mounted holder or a floor-mounted one?
Wall mounted. The 2400LR pairs a wall unit with a 1-1/2 inch armature mounted to the door face, so the magnet sits on the wall behind the open door. If your door swings back to open floor rather than to a wall, or the wall behind it is glass or won't take the load, a wall unit isn't the right choice and you want a floor-mounted electromagnetic holder instead.
8) What finishes does the ABH 2400LR come in, and can I match the door holders already in my building?
Six finishes are offered on the 2400LR: painted aluminum, painted brass, painted bronze, painted black, painted dark bronze, and satin aluminum. Property managers standardizing a fleet of openings can generally hold one finish across every holder in the building, and the painted options are the ones that blend into a painted wall rather than the hardware.
9) Does the 2400LR come with a key cylinder or any keyed override?
No. The 2400LR is a magnetic hold-open device with no keyed function and no cylinder to specify. Nothing about keyway, keying, or a master key system applies to it. The only ordering decision is the finish.
