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 EM505-24120-695 – Frequently Asked Questions

1) Will the DORMA EM505 door holder work on a door that swings either way, or do I have to specify handing?
Handing isn't a factor. The EM505 is non-handed, so one part number covers left and right hand openings. The catch plate on the door uses a ball-shaped pivot arm that adjusts to line up with the magnet, which is what lets a single unit serve either swing. Order it by finish only.
2) What voltage does the DORMA EM505 electromagnetic door holder run on?
The EM505 is dual voltage: 24VDC/24VAC or 120V. That means one unit covers both the low-voltage side of a fire alarm panel and a straight 120V line, so you don't have to decide the power source before you order. For a facility standardizing holders across floors, the same model works whether the release signal comes off a 24V FACP circuit or line voltage.
3) Is the EM505 a wall mount or a floor mount door holder?
Wall mount, semi-flush, for a single door. The EM Series is built in both floor- and wall-mounted magnet versions, and the EM505 is the wall unit. If the door parks against a low wall or a column face, this is the one. If there's no wall in the swing path and the door has to be held off the floor, you want the floor-mounted magnet in the same series instead.
4) Do I need a mounting bracket to install the EM505 wall magnet?
No bracket needed. Brackets are not required for recessed, flush, or surface mounting of EM Series holders, so the semi-flush wall install goes in without extra hardware to source. Where the gap between the door and the wall is larger than the catch plate can reach, optional extension rods are what closes the distance, and add-on catch plate extensions are available on the series as well.
5) My door is further off the wall than the short catch plate reaches. What do I order?
The EM505 comes with the short catch plate, which suits doors that park close to the wall. For a wider gap, the EM Series offers add-on catch plate extensions and optional extension rods to make up the distance between door and wall. Measure from the door face to the wall at the held-open position before you decide which you need, because the short plate on its own is the shortest reach in the family.
6) Will an electromagnetic door holder release properly on an ADA opening with a light closer?
Yes, and that's the specific reason to use an EM Series magnet. It's built with low residual magnetism, so it lets go cleanly instead of hanging on to the plate after power drops. That matters on ADA-compliant openings where the closer is set to minimum spring force and there isn't much energy available to pull the door off the magnet. Pair it with a DORMA closer for the controlled release and closing part.
7) Does a door holder replace the door closer, or do I need both?
You need both. The EM505 is a hold-open device only: a door-mounted catch plate and a wall-mounted electromagnet that keeps the leaf open until the circuit drops. It has no closing mechanism of its own. The DORMA EM Series is meant to run in conjunction with DORMA door closers, which is what actually returns and latches the door once the magnet releases. Budget a closer per opening on top of the holder.
8) Is the DORMA EM505 door holder ANSI/BHMA certified?
Yes. DORMA EM Series electromagnetic door holders are ANSI/BHMA certified. For institutional specs that call out certified hold-open hardware, the EM505 wall mount satisfies that line item.
9) Can I use one EM505 on a pair of doors?
No. The EM505 is configured for a single door, one magnet holding one catch plate. A pair of doors needs a holder per leaf, since each leaf carries its own catch plate and needs its own wall magnet aligned to it. Order two units and wire them to the same release circuit.
10) What finishes does the DORMA EM505 come in, and will it match the rest of my door hardware?
Three finishes: 689 aluminum painted, 695 dark bronze, and 696 satin brass. Those are standard BHMA finish codes, so 689 lines up with clear-anodized aluminum storefront and painted closers, 695 with dark bronze entrances, and 696 with brass trim. If you're standardizing a corridor or a hotel floor, pick the code already on your closers and the holder will read as part of the same set.
11) Is the EM505 quiet enough for a hospital corridor or a hotel guest floor?
Silent operation is one of the EM Series design points, and the series is aimed squarely at hotels, hospitals, and nursing homes where controlled release and closing of doors is needed for safety or convenience. There's no mechanical latch or solenoid clack in the hold, just magnetic contact against the catch plate.
