Product details

Economical package for controlled release and closing of doors

The DORMA EM Series door holders are composed of a door mounted catch plate and a floor- or wall-mounted electromagnet. This series serves as an economical package for use in conjunction with DORMA door closers whenever controlled release and closing of doors is necessary for safety or convenience such as in hotels, hospitals, and nursing homes.

Superior reliability

The EM Series magnets offer superior reliability with built-in protection and low residual magnetism so they release easily even in applications meeting ADA requirements with minimal spring force door closers.

Several mounting methods for EM Series Electromagnetic Door Holders

Brackets are not required for recessed, flush, or surface mounting. The catch plate on the door features a ball-shaped pivot arm for adjustability to further ensure perfect alignment. Optional extension rods are available to accommodate greater distances between the door and wall.

Dormakaba EM509-24120-689 – Frequently Asked Questions

1) Will the DORMA EM509 door holder work on a left-hand and a right-hand door, or do I have to specify handing?
No handing to specify. The EM509 is non-handed, so the same part works on left- or right-swing openings. It is a wall-mounted magnet paired with a catch plate on the door, and the catch plate uses a ball-shaped pivot arm so it can be adjusted to line up with the magnet either way. Order by finish only.
2) What voltage do I need to run to a DORMA EM509 electromagnetic door holder?
The EM509 is dual voltage: 24VDC/24VAC or 120V. That means one part number covers both a low-voltage run off a fire alarm panel or access control power supply and a straight 120V line, so you do not have to decide the power source before you order. Wire it to whichever the building already gives you at that wall location.
3) Do I need a mounting bracket to install a DORMA EM509 flush wall mount door holder?
No bracket. The EM Series magnets mount recessed, flush, or surface without brackets, and the EM509 is the completely flush wall-mount version, so it sets into the wall face rather than standing off it. What you do need is the catch plate on the door leaf, which comes as part of the holder, plus power to the magnet location.
4) My door sits further off the wall than the magnet reaches. Can I still use an EM509?
Yes, with an extension. Optional extension rods are available for the EM Series to cover greater distances between the door and wall, and add-on catch plate extensions are offered as well. The catch plate itself is adjustable, so short misalignments are taken up at the plate. Longer gaps are what the extension rods are for, and they are ordered separately from the holder.
5) Will an EM509 hold open a pair of doors, or do I need two?
One per leaf. The EM509 is specified for single-door application, so a pair of doors needs a holder at each leaf. Each magnet catches its own door-mounted plate, and each needs power run to it.
6) Will an EM509 release cleanly with a low-force ADA closer, or will it stick?
It is built for exactly that case. The EM Series magnets use low residual magnetism so they let go easily even in applications meeting ADA requirements where the door closer is set to minimal spring force. Residual magnetism is what makes a cheap holder hang on after power drops and stall a light closer; the EM design and its built-in protection are aimed at that failure.
7) Does an electromagnetic door holder close the door by itself when the fire alarm trips?
No, and this is the most common misunderstanding on these. The magnet only holds the door open; when power drops it releases and the door closer swings the door shut. The EM Series is sold as a package to use with DORMA door closers for controlled release and closing. If there is no closer on that door, adding an EM509 gets you a door that opens and stays put, not one that shuts on alarm.
8) Should I use a wall-mounted door holder or a floor-mounted one?
It depends on where the door lands when it is held open. The EM Series is built both ways: the EM509 is the wall-mount magnet, which suits a door that swings back against a wall within reach of the leaf. A floor-mounted magnet is the answer when the door parks away from any wall, out in an opening or corridor. Both use the same door-mounted catch plate arrangement, so the decision is purely about what surface is there to mount to.
9) What finishes does the DORMA EM509 door holder come in, and can I match the other hardware in the building?
Three finishes: 689 aluminum painted, 695 dark bronze, and 696 satin brass. Those are the standard BHMA finish codes, so 689 lines up with painted aluminum closers and exit devices, 695 with dark bronze, and 696 with satin brass trim. For a facility standardizing across many openings, pick the code that matches the closers already specified rather than matching by eye.
10) Is the DORMA EM509 rated for commercial use in a hospital or hotel corridor?
Yes. The EM509 is a commercial-duty holder, and the EM Series door holders are ANSI/BHMA certified. Dormakaba positions the series for hotels, hospitals, and nursing homes, where doors need to stand open for traffic but release and close on command for safety.
11) Is the EM509 catch plate adjustable if my door and wall are not perfectly aligned?
Yes. The door-mounted catch plate has a ball-shaped pivot arm so it can swivel to meet the magnet face square, which is what you need on a door that racks slightly or a wall that is not plumb to the leaf. Contact across the full magnet face is what gets you the rated hold; a plate meeting it at an angle will drop the door.
