DORMA 8956 EMR/TDE Series

Holder/Release Devices with Integral Door Closers

The EMR Series holder/release device incorporates a photoelectric detector and can control the spread of smoke and fire in a specific location or throughout the building if wired into a central alarm panel.

Holder/release devices ANSI/BHMA certified.

  • Three models included
  • Interfaces with new or existing fire/smoke control systems
  • Can be wired for concealed or surface wiring
  • EMR can control one EMF unit for pair of doors
  • Patented hold open design
 

Product details

Three models included

The EMF/EMR Series includes three models for price and door closer feature/function considerations. The TS93 in Contur Design, with the extra efficient cam and roller technology, can be used on larger doors, while the 8900 rack and pinion closer offers a narrow projection for less cost. When value engineering is a concern, the 8600 meets the need.

Patented hold open design

The EMF/EMR Series’ patented hold open design prevents damage to the door, frame, holder/release device, or other installed hardware. This design enables initial hold while allowing the door to be manually opened beyond the hold open point.

Compatibility and wiring

The EMF/EMR Series is compatible with new or existing fire/smoke control systems and can be wired for concealed or surface wiring.

Door shuts in case of an alarm state or power failure

In the case of an alarm state signaled by the central control system or main power failure, current to the electromagnetic hold open device is interrupted, thus allowing the door closing mechanism to take over and shut the door.

Dormakaba 8956-EMR-TDE-RH-689 – Frequently Asked Questions

1) Do I need a separate smoke detector to use the DORMA 8956 EMR hold-open closer?
No separate detector is needed at the opening. The EMR version has a photoelectric detector built into the unit, so it can drop the door on smoke at that specific location on its own. If you want building-wide release instead, it wires into a central fire/smoke alarm panel, and it works with new or existing systems. If your building already has full detection and a panel, the non-detector EMF unit is the one to look at.
2) What happens to the door if the power goes out on a DORMA 8956 EMR holder/release?
The door closes. Current to the electromagnetic hold open is interrupted on either an alarm signal from the control panel or a main power failure, and the integral closer takes over and shuts the leaf. It's fail-safe by design, which is the whole point of a hold-open on a smoke barrier: nothing keeps the door propped once power drops.
3) Do I have to specify handing when ordering the DORMA 8956 EMR/TDE?
Yes, handing is required. The 8956 EMR/TDE is a handed device and comes left hand or right hand. On a double egress pair the two leaves swing opposite ways, so a pair typically takes one of each rather than two of the same hand. Get the hand wrong and the track and arm land on the wrong face of the door.
4) Does the DORMA 8956 EMR meet ADA requirements for opening force?
No. The 8956 EMR/TDE is not an ADA compliant unit. It's a size 5 to 6 heavy duty closer, and that spring range sits above what a barrier-free opening force allows. If the opening has to meet accessibility opening-force requirements, this is not the device for it, and you should be looking at a lower-size or power-operated solution instead.
5) Can I use the DORMA 8956 EMR on a single door instead of a double egress pair?
The 8956 EMR/TDE is configured for double egress mounting, so it's specified for that cross-corridor pair condition rather than a standard single opening. For a single leaf, or for the companion leaf being controlled from a detector unit, the EMF version of the series is the counterpart, and one EMR can drive one EMF. Match the mounting configuration to the opening rather than adapting this one.
6) Is the DORMA 8956 EMR closer strong enough for a heavy corridor door?
It's a heavy duty, Grade 1 closer sized 5 to 6, which is the range for wide or heavy openings rather than a light interior leaf. It's a commercial device, not a residential one. The cam and roller track is the higher-efficiency arm arrangement in the EMF/EMR family and is what lets the unit handle larger doors.
7) Can I run the wiring for the DORMA 8956 EMR on the surface instead of through the frame?
Both are supported. The EMR can be wired concealed or surface, so an existing opening that was never prepped for a raceway doesn't have to be drilled out. That matters on a retrofit into an occupied building, where cutting the frame for concealed wire is the expensive part of the job.
8) Will the DORMA 8956 EMR get damaged if someone pulls the door past the hold-open point?
No. The hold open design on the EMF/EMR Series is patented specifically to allow the door to be pushed or pulled manually beyond the hold open point without damaging the door, the frame, the holder/release unit, or other hardware on the opening. On a high-traffic corridor where staff routinely shove a held-open leaf further back, that's the failure mode this design removes.
9) What is the difference between an electromagnetic hold-open closer and a plain closer with an electric hold-open track arm?
Both hold a door open and release it on alarm, but they differ in what triggers the release. The DORMA 8956 EMR/TDE carries its own photoelectric detector, so it can drop the door on smoke at that opening even with no panel signal, and it can be tied to a central fire/smoke system as well. The Cal-Royal CR441EHO is a Grade 1 closer with an electronic hold-open track arm, which relies on the building system to cut power. If the opening is a smoke barrier in a building without local detection at that door, the self-detecting unit is the one that does the job unaided.
10) Are DORMA EMR holder/release devices certified to a hardware standard?
The holder/release devices in the EMR Series are ANSI/BHMA certified, and the 8956 EMR/TDE is a Grade 1 unit. For a facility standardizing corridor smoke doors across a campus, that Grade 1 designation plus the certification is what a spec on the drawing normally calls for on this kind of opening.
11) What finishes does the DORMA 8956 EMR/TDE come in?
Six finishes, and each is available in both hands: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze, and 696 satin brass. For a property manager matching a run of corridor doors, 689 aluminum and 690 dark bronze are the usual pairings with existing DORMA closers on the same floor.
