OVERVIEW

The ED50LE Low Energy Swing Door Operator employs an innovative, and super-quiet, electromechanical drive that is a perfect solution for facilities who want a quick, quiet, and painless transition from manual doors to touch-free access such as commercial buildings, hospitals, schools, hotels and multifamily buildings.

This swing door operator can automate new or existing swing doors with a push plate, wave plate, or other actuator devices. 

The ED50LE's advanced automatic power assist combines minimal push forces (as low as ANSI size 1) with reliable closing. All common applications for outswing and inswing doors — either with push arm or slide track arm for tight side clearance.  

The ED50LE is easy to install and makes existing doors easily accessible.

  • Seamless control with integrated hardware power supply and relay.
  • Built-in door position status, indicating door open or door closed.
  • Close and latch in case of power loss (adjustable closing speed on loss of power).
  • Hardware pre-load functionality for reliable operation.
  • Connection to any access control system with built-in interface.
  • Independently tested to 1 million cycles
  • ED50LE offers full power durability in a low-energy setting.

 

FEATURES

Advanced power assist 

When operated manually, the ED50LE demands little physical effort. Advanced power assist through the entire opening cycle makes even the heaviest-rated door feel light. 

Fully ADA compliant 

The operator is especially helpful for children, the elderly, persons with disabilities, or those carrying objects or pushing carts. This fully ADA-compliant device opens doors at precisely controlled speeds and forces, assuring safety for all users. 

Advanced features 

The ED50LE also includes a blow-open feature for smoke ventilation (per NFPA code 92B), permanent hold-open, and an onboard power supply delivering 1.5 amps @ 24-volt DC, which eliminates the need for a secondary power supply. It includes 12 programmable options to accommodate even the most challenging door installations. 

Small footprint 

In addition, the ED50LE low energy swing door operator boasts a small footprint, up to 65 percent smaller than some other manufacturers' operators.

Dormakaba DOR-ED50LE-PUSH-DA – Frequently Asked Questions

1) Can the DORMA ED50LE be added to an existing manual swing door, or does it only work on new openings?
Existing doors are the normal application. The ED50LE is a surface applied operator that automates new or existing swing doors, so the header unit mounts to the face of the frame or door rather than being concealed inside it, and the opening does not have to be rebuilt. It covers inswing and outswing doors, with a push arm or a slide track arm where side clearance is tight. The header measures 2-3/4 x 5-1/8 x 34 inches with the Fine cover, so check you have a clear, flat run of mounting surface that long across the head of the opening before you order.
2) Do I have to order the ED50LE left hand or right hand?
Handing is not part of the order. The ED50LE operator is non-handed. What you do have to specify is arm type and finish: PULL arm in clear anodized aluminum is part number 7266003, PULL in dark bronze anodized is 7266004, PUSH arm in clear anodized is 7266005, and PUSH in dark bronze anodized is 7266006. Both finishes are built in both arm types, so the finish decision and the arm decision are independent of each other.
3) What happens to a door on an ED50LE operator when the building loses power?
The door closes and latches on loss of power, and the closing speed for that condition is adjustable, so it is set during commissioning rather than left to gravity. That matters on an opening that has to stay secure or stay latched in a smoke-rated corridor. The ED50LE also carries a blow-open feature for smoke ventilation per NFPA code 92B and a permanent hold-open setting, both selected through its 12 programmable options.
4) Do I need a separate 24V power supply and transformer to run a DORMA ED50LE?
No separate power supply is needed. The ED50LE has an onboard supply delivering 1.5 amps at 24 volts DC, which is what removes the secondary power supply from the job, and it includes an integrated relay plus a built-in interface for connection to any access control system. Budget the 1.5 amp figure when you decide how many wave plates, card readers, or electric strikes you intend to hang off it.
5) What else do I have to buy to make a touchless entrance with the ED50LE operator?
The ED50LE is the operator itself, and it is activated by a push plate, wave plate, or other actuator device, so the actuators and their mounting are the pieces that finish the entrance. Its onboard 1.5 amp 24VDC supply powers that side of the job without a separate transformer, and the built-in access control interface is where a reader or REX signal lands. If you would rather buy switches bundled with the operator, the Norton Rixson 5700 Series 5740K2 is sold as a complete kit with touch-free switches, and the Norton Rixson 4500 Series 4540 comes with an RF square switch and a WiFi interface.
6) Can people still push the door open by hand when the ED50LE operator is not activated?
Yes, and that is a designed mode rather than a fallback. Operated manually, the ED50LE applies advanced power assist through the entire opening cycle, with push forces as low as ANSI size 1, so a heavy commercial door still feels light to a child, an older resident, or someone carrying boxes. Manual use does not defeat the closing function either, since the unit closes and latches reliably including on loss of power.
7) What is a comparable heavy duty low energy swing door operator to the DORMA ED50LE?
The DORMA ED50LE is a heavy duty low energy operator, and two Norton Rixson operators are carried at the same duty level: the Norton Rixson 5200 Series Low Energy Power Operator (RIX-5200) and the Norton Rixson 6000 Series low energy operator (NOR-6011). The working difference is the drive. The ED50LE uses an electromechanical drive with an onboard power supply delivering 1.5 amps at 24 volt DC, so no secondary supply is needed, while the Norton Rixson 6000 Series operator is electrohydraulic. The ED50LE is non-handed and covers outswing and inswing openings with either a push arm or a slide track arm; the NOR-6011 is configured with a slide track arm and pull side mounting.
8) The opening needs a push side operator instead of pull side - what changes when substituting for the DORMA ED50LE?
The DORMA ED50LE is non-handed and the mounting side is an ordering choice on the operator itself: it is built as a pull side arm unit under MPN 7266003 in clear anodized aluminum and 7266004 in dark bronze anodized, and as a push side arm unit under 7266005 in clear anodized aluminum and 7266006 in dark bronze anodized. Cross-shopping the LCN Benchmark line, the mounting side is a separate model rather than an option: the LCN 9131 is the pull side mount operator and the LCN 9142 is the push side mount operator. So a Benchmark quote written against the wrong number cannot be corrected by an option change the way an ED50LE order can.
9) How far does the ED50LE swing door operator open the door?
Opening angle is 110 degrees. That is enough to clear a wheelchair, a housekeeping cart, or a gurney through a standard opening, and it is worth checking against what is beside the door: a return wall, a sidelite mullion, or furniture inside the swing path will govern before the operator does. Speed and force through that arc are controlled, and the ED50LE is described as fully ADA compliant.
10) Is the ED50LE operator rated for a high traffic entrance like a hospital or apartment lobby?
It is a commercial, heavy duty unit and has been independently tested to 1 million cycles, which is the number to quote when the opening is a main lobby, a corridor cross door, or a clinic entrance. Dormakaba positions it as full power durability in a low energy setting, meaning the door still opens under the reduced speeds and forces a low energy operator requires, without a heavy duty drive being the limiting factor.
11) Electromechanical or electrohydraulic low energy operator, which should I use?
The DORMA ED50LE runs an electromechanical drive, which is the quiet option and the one that carries an onboard 24VDC supply and a built-in access control interface, so most of the electrical integration happens inside the header. The electrohydraulic alternatives ZenSupply carries are the Norton Rixson 6000 Series, a low energy electrohydraulic operator with a slide track arm and pull side mounting, and the heavy duty Norton Rixson 5700 Series electrohydraulic power operator. Hydraulic units are the traditional choice where an existing spec calls for them; electromechanical is where noise in a corridor or a patient area is a concern.
12) My door has almost no side clearance on the hinge side. Will a low energy operator still work?
That is the case a slide track arm is for. The ED50LE handles all the common inswing and outswing applications with either a push arm or a slide track arm, the slide track being the one specified for tight side clearance where a projecting push arm has nowhere to go. Confirm the arm style against your reveal before you commit, since arm type is fixed at order. If a pull side slide track arrangement is what the drawing calls out from another manufacturer, the Norton Rixson 6000 Series operator is listed with a slide track arm and pull side mounting.
13) Do I order a different model of the ED50LE for push side versus pull side mounting?
Same model either way. The ED50LE is non-handed and the mounting difference is handled by the arm type you select, PULL or PUSH, on the one operator. That is a different ordering pattern from LCN's Benchmark line, where the 9131 is the pull side mount model and the 9142 is the push side mount model, so the choice is made by picking a separate part number. If you are standardizing a building, ordering one ED50LE model in two arm types keeps the spare parts and the programming identical across openings.
14) Will a low energy operator fit over a door where the header is already crowded with a closer or a card reader?
Footprint is one of the ED50LE's arguments. The cover is 2-3/4 by 5-1/8 by 34 inches, described as up to 65 percent smaller than some other manufacturers' operators, and the power supply and relay are inside it, so there is no separate power supply box to find room for above the ceiling or in a nearby closet. Measure the 34 inch run and the 5-1/8 inch projection against what is already on the head before ordering.
15) Can I tell from the access control system whether an automatic door is actually closed?
The ED50LE has built-in door position status, reporting door open or door closed, and an integrated relay plus an interface for connection to any access control system. For a property manager or an integrator that means the operator itself can report state back to the head end without adding a separate door position switch in the frame. Twelve programmable options cover how the operator behaves on those inputs, including permanent hold-open.
16) Which low energy operators use an electromechanical drive like the DORMA ED50LE, and which are hydraulic?
The DORMA ED50LE runs an electromechanical drive. Among the operators carried alongside it, the LCN 9131 and LCN 9142 Benchmark operators are also low energy electromechanical units, and the SDC AUTOP Series low energy automatic operator runs under microprocessor control. On the hydraulic side, the Norton Rixson 6000 Series operator (NOR-6011) and the Norton Rixson 5700 Series complete kit (NOR-5740K2) are electrohydraulic. For a facility standardizing on one service approach across a run of doors, this is the split that decides which spare parts and which adjustment procedure the maintenance team keeps.
17) Is there a more compact operator than the DORMA ED50LE for a narrow header or a lighter door?
The DORMA ED50LE header unit measures 2-3/4 inch by 5-1/8 inch by 34 inch in the Fine cover. If the header run is shorter than that or the door is on the lighter side, the LCN 6440 COMPACT automatic operator module is built for doors up to 185 pounds and runs on 24VDC, as does the LCN 6440XP COMPACT operator. Both LCN COMPACT units and the ED50LE are low energy operators, so the actuator and access control side of the job is approached the same way; what differs is the size of the case going on the header and the door weight the unit is built around.
18) I need the touchless switches supplied with the operator - what should I order instead of the DORMA ED50LE?
The DORMA ED50LE automates a new or existing swing door with a push plate, wave plate, or other actuator device, and the actuators are specified separately from the operator. If the job is better served by an operator supplied with its switches, the Norton Rixson 5700 Series electrohydraulic power operator ships as a complete kit with touch-free switches (NOR-5740K2), and the Norton Rixson 4500 Series low energy operator (RIX-4540) comes with an RF square switch and a WiFi interface. The ED50LE stays the closer match on drive type, since it is electromechanical and the 5700 Series is electrohydraulic.
19) Which operator should I look at instead of the DORMA ED50LE if the door needs to tie into a networked or wireless control?
The DORMA ED50LE has a built-in interface for connection to any access control system, plus built-in door position status that reports door open or door closed, and a hardware power supply and relay integrated into the operator. Where the requirement is a wireless link rather than a wired access control tie-in, the Norton Rixson 4500 Series low energy door operator (RIX-4540) is supplied with a WiFi interface and an RF square switch. Both are low energy swing door operators, so the arm and header work at the opening is comparable; the difference is whether the control path is the ED50LE built-in access control interface or the 4500 Series wireless interface.
20) Is there an ADA compliant pull side operator equivalent to the DORMA ED50LE for a commercial entry?
The DORMA ED50LE is fully ADA compliant, opens at precisely controlled speeds and forces, and is ordered in a pull side arm configuration under MPN 7266003 in clear anodized aluminum or 7266004 in dark bronze anodized. A comparable pull side unit is the LCN 9131 Benchmark low-energy electromechanical automatic door operator, which is specified with pull side mount and ADA compliance. Both are electromechanical low energy operators for commercial openings; the ED50LE additionally carries a heavy duty rating and opens to 110 degrees.
21) What finishes does the DORMA ED50LE operator come in, and will it match the storefront?
Two finishes: clear anodized aluminum and DA dark bronze anodized. Both are the standard anodized tones used on aluminum storefront and entrance framing, so the header reads as part of the frame rather than an add-on, and both are available with either arm type. Clear anodized suits mill finish or clear anodized framing, dark bronze suits the dark bronze storefront common on older commercial and multifamily entrances.
22) What are the alternatives to the DORMA ED50LE if I need obstacle detection or wireless setup?
Those are features to shop for by model. The Cal-Royal 8600 Series low energy automatic swing door operator is listed with obstacle detection, and the Norton Rixson 4500 Series 4540 comes with an RF square switch and a WiFi interface for wireless actuation and setup. The SDC AUTOP Series is a low energy operator with microprocessor control. Where the ED50LE earns its place instead is the quiet electromechanical drive, the onboard 1.5 amp 24VDC supply, and 1 million tested cycles on a heavy duty unit.
23) The spec calls for obstacle detection on the automatic operator - is the DORMA ED50LE the right pick?
The DORMA ED50LE is a low energy operator that opens at controlled speeds and forces, is fully ADA compliant, and closes and latches on loss of power with an adjustable closing speed. Where the drawing specifically calls out obstacle detection as a named feature of the operator, the Cal-Royal 8600 Series low energy automatic swing door operator (CAL-8600) is specified with obstacle detection. Both are low energy swing door operators mounted at the header, so the opening prep is similar; write the order against whichever one the submittal language matches.
24) What is the difference between the LCN 6440 and the 6440XP when cross-shopping against the DORMA ED50LE?
They are two separate part numbers, not a single item with a suffix. The LCN 6440 is the COMPACT automatic operator module with 24VDC power and touchless access for 185 pound doors and belongs to the 6400 Series, while the LCN 6440XP is the COMPACT automatic door operator with 24VDC low-energy operation and 185 pound door capacity and belongs to the 6440XP Series. A quote written for one is not fillable with the other. The DORMA ED50LE sits under the ED50 Series as model ED50LE, ordered by arm type and finish rather than by series suffix.
25) Which alternative to the DORMA ED50LE offers programmable control for a difficult opening?
The DORMA ED50LE includes 12 programmable options to accommodate challenging door installations, along with a blow-open feature for smoke ventilation per NFPA code 92B, permanent hold-open, and an adjustable closing speed on loss of power. Where a microprocessor-controlled alternative is wanted, the SDC AUTOP Series low energy automatic door operator (SDC-AUTOP) is specified with microprocessor control. Both are low energy automatic swing door operators, so the actuator and header approach at the opening is comparable.
