DORMA 1856 Series

Holder/Release Device with Integral Door Closer, with or without Smoke Detector

The 1800 Series is an electromagnetically controlled door closer, available with or without integral smoke detector-power supply for use on fire and/or smoke barrier doors.

Holder/release devices ANSI/BHMA certified.

  • Available with or without integral smoke detector
  • Hold open function
  • Swing free function
  • Reliable door closing control

Product details

The DORMA 1800 Series Hold Open (H) function is designed for buildings where it is desirable to have smoke/fire doors in the open position under normal circumstances, but which must close upon loss of current. These units will operate as a standard door control, whether or not power is applied.

Swing free function

The DORMA 1800 Series Swing Free (SF) function is designed for buildings where it is desirable to have fire/smoke doors operating as if there were no closing device fitted under normal circumstances, but must be self-closing under alarm or loss of current.

Smoke and fire control

The 1800 Series door closer will allow unimpeded, easy access throughout a building while not affecting its integrity to control the spread of smoke and/or fire.

Door closing control

Upon interruption or loss of current in either the H or FS specification, the unit will automatically close the door from any angle of opening. This is caused by release of the electromagnetic solenoid, thus allowing the door closer to perform its function.

Dormakaba 1856-HT-RH-24V-689 – Frequently Asked Questions

1) What's the difference between the hold open and swing free versions of the DORMA 1856?
Two arm options on the 1856, and they behave very differently day to day. Hold Open Slide Track (HT) parks the door open and lets it close on loss of current, working as a normal door closer whether or not power is applied. Swing Free Slide Track (SFT) lets the door swing as though no closer were fitted at all, then goes self-closing under alarm or power loss. Pick SFT for patient rooms or corridors where you want free door movement; pick HT where the door should stand open until the alarm drops it. Either way, when current is interrupted the electromagnetic solenoid releases and the closer shuts the door from any angle of opening.
2) Will the DORMA 1856 close a heavy fire door?
It is a heavy duty, Grade 1 closer sized 5 to 6 and rated to a 180 pound door, so it handles the wide, heavy openings you find on cross-corridor and stairwell fire doors. Sizes 5 and 6 are the upper end of the spring range, which is what a 180 pound leaf needs.
3) Do I have to specify handing when I order a DORMA 1856?
Yes, handing is a required choice. The 1856 is ordered Left Hand or Right Hand, so stand outside the opening on the side the door swings away from you and note which edge the hinges are on. Order the wrong hand and the track and arm will not mount correctly to the leaf. You also specify pull side mounting, arm type, finish and voltage on the same order.
4) What voltage does the DORMA 1856 electromagnetic holder need?
Order it as either 120 VAC or 24 VAC/VDC. The 24 volt version is the one that ties into a fire alarm panel or a low voltage power supply on a released circuit; the 120 VAC version runs off line power. Match this to whatever the alarm contractor is bringing to the head of the frame, because it is fixed at the time of order, not field selectable.
5) Is the DORMA 1856 pull side or push side mounted, and where does it attach?
Pull side, frame mounted. The closer body and slide track go on the frame face on the pull side of the opening, with the arm running into the track on the door. If your opening only allows push side hardware, or the frame face is obstructed on the pull side, this is the wrong configuration and you want a push side model in the 1800 family instead.
6) Does the DORMA 1856 need a separate magnetic door holder and closer?
No, it is one unit. The 1856 combines the electromagnetic holder/release and the door closer in a single surface mounted body on a slide track, so you are not buying and wiring a wall or floor mounted magnet plus a separate closer, and you are not coordinating two mounting patterns on the same opening. The holder/release function is ANSI/BHMA certified. A version with an integral smoke detector and power supply is also built in the 1800 Series if you need standalone detection rather than a signal from the building panel.
7) Is the DORMA 1856 ADA compliant for opening force?
No. The 1856 is not an ADA compliant closer. It is a size 5 to 6 heavy duty unit built to control a 180 pound fire door, and that spring power is above what an accessible opening force allows. On an opening that has to meet accessibility requirements, you need a lower powered or adjustable closer, or a power operator, rather than this one.
8) What happens to the door on the DORMA 1856 if the power goes out?
The door closes. On either the hold open or swing free version, interrupting or losing current releases the electromagnetic solenoid and the built-in closer shuts the door from whatever angle it is sitting at. That is the fail-safe behavior a fire and smoke barrier opening needs, and it is the same result whether the signal comes from the alarm panel or the building simply loses power.
9) What is the closest equivalent to a DORMA 1856 electromagnetic hold open track closer from another manufacturer?
The Cal-Royal CR441EHO is the nearest peer: a Grade 1 door closer with an electronic hold-open track arm, so it combines the closer and the electrified hold-open into one surface-mounted unit the same way the 1856 does. The DORMA 1856 is also Grade 1 and heavy duty, sized 5 to 6, and it is offered in either an HT hold open slide track or an SFT swing free slide track. If the opening needs swing free behavior, where the door swings as though no closer were fitted until the alarm drops power, the 1856 SFT is the one that covers it; the CR441EHO is described as an electronic hold-open arm.
10) Can a Cal-Royal CR441EHO be used in place of a DORMA 1856 on a fire door hold open?
Both are Grade 1 electrified hold-open closers, so the function is comparable, but three things decide the swap. The DORMA 1856 is handed left or right and frame mounted on the pull side with a 48 inch track, so the replacement has to match that prep. It is supplied for 120 VAC or 24 VAC/VDC, so the new unit has to match the voltage the fire alarm panel or power supply already delivers. And the 1856 carries a door weight rating of 180 pounds with 180 degree opening. Confirm the CR441EHO track length, handing and voltage against the existing frame prep before ordering it as a drop-in.
11) Can the DORMA 1856 hold a door open at 180 degrees?
Rated for a 180 degree opening, so it will work on doors that swing back flat against a wall, provided nothing in the opening (wall stop, adjacent leaf, projecting trim) stops the leaf first. The slide track arm keeps the hardware tight to the door, which is what allows the full swing.
12) What is the track length on the DORMA 1856?
48 inches. That is a long track, so check the frame face and the door width you are mounting to before you commit, and confirm no wall return, transom bar or adjacent frame member cuts into the run. On narrower openings the track length is usually the limiting dimension, not the closer body.
13) What is a cheaper alternative to the DORMA 1856 if I just need electronic hold open?
If the requirement is straight electronic hold open and not swing free, the Cal-Royal CR441EHO is a Grade 1 door closer with an electronic hold-open track arm and covers the same basic job. Go with the 1856 when you need the swing free arm option, a choice of 120 VAC or 24 VAC/VDC at the time of order, or six architectural finishes to match existing openings.
14) Is the DORMA 1856 suitable for a house or light commercial door?
It's a commercial unit, heavy duty and Grade 1, aimed at fire and smoke barrier doors in institutional and commercial buildings. On a light interior or residential door the size 5 to 6 spring is far more power than the leaf needs, and the unit assumes a wired 24 volt or 120 volt supply released by the fire alarm system. For a light door with no alarm interface, a standard non-electrified closer is the right part.
15) Is a standard Grade 1 door closer with a hold open arm the same thing as a DORMA 1856?
No. A mechanical hold open arm stays open until someone pushes the door shut, which is not permitted on a smoke or fire barrier door. The DORMA 1856 is an electromagnetically controlled closer: on interruption or loss of current the solenoid releases and the closer shuts the door from any angle of opening, and the hold/release devices are ANSI/BHMA certified. The Cal-Royal CR441EHO is the peer that shares that electronic hold-open track arm behavior rather than a friction arm. If the door is on a fire alarm interface, the electrified version is the one specified.
16) Which electrified closer should I use when the door needs to feel free-swinging instead of held open?
Use the DORMA 1856 in the SFT swing free slide track configuration. Under normal power the door operates as if no closing device were fitted, and it becomes self-closing on alarm or loss of current, which suits patient room and resident room doors where users should not have to fight a closer. The HT hold open slide track version is the one for doors parked in the fully open position instead. The Cal-Royal CR441EHO is offered as an electronic hold-open track arm closer, so it is the peer for the hold-open application rather than the swing free one.
17) What finishes does the DORMA 1856 track closer come in?
Six: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze and 696 satin brass. Property managers standardizing a building normally match the 689 or 690 already on the other closers, since those are the two that show up most on existing commercial openings. The housing and track are aluminum under the finish.
18) I need a matching electrified closer in dark bronze across a set of openings. What are my options?
The DORMA 1856 covers a finish range wide enough to standardize a building: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze and 696 satin brass, in both handings and both the HT and SFT track arms. That lets one Grade 1 heavy duty electrified closer carry the whole fleet with the finish held constant while the arm function varies by opening. Comparable Grade 1 electrified hold-open closers such as the Cal-Royal CR441EHO should be checked for finish match before mixing them into the same corridor.
