Product details

Features

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 8656-EMR-TDE-RH-689 – Frequently Asked Questions

1) What does the DORMA 8656 EMR/TDE actually do on a smoke barrier door?
It holds the door open electromagnetically and releases it on command. The 8656 EMR has a built-in photoelectric smoke detector, so it can drop the door on its own local smoke reading, or be wired into a central fire/smoke alarm panel so the whole building releases together. On alarm or on loss of main power, current to the magnet stops and the integral closer shuts the door. Closer and holder are one surface-mounted track unit, so you are not buying a separate closer and a separate mag holder.
2) Will the 8656 EMR/TDE work on a double egress frame?
That is exactly what the TDE version is built for. It is the double egress configuration, mounted pull side. On a double egress pair each leaf swings the opposite way, so the pull side face is different on each leaf, which is why the geometry is specific and not interchangeable with a standard pull side or regular arm unit.
3) Do I have to specify handing when ordering the DORMA 8656 EMR/TDE?
Yes, it is a handed unit. Order left hand or right hand, and it is determined at order time, not adjustable in the field. Both hands are offered in all six finishes. On a double egress pair you will typically need one of each hand to cover both leaves.
4) Can one 8656 EMR control both leaves of a pair of doors?
Yes. The EMR unit, which carries the detector, can control one EMF unit on the opposite leaf. So on a pair you order the EMR (detector) for one leaf and an EMF (non-detector) for the other, and the EMR's detection or the panel signal releases both together. Ordering two detector units on the same pair is not necessary.
5) Does the 8656 EMR meet ADA opening force requirements?
No. The 8656 EMR/TDE is not an ADA compliant closer, and at a size 5 to 6 spring setting the opening force will be well above what a barrier-free opening allows. If the door is on an accessible route and has to meet ADA opening force, this is not the right unit; look at a lower-size or power-operated solution for that opening.
6) Is the Cal-Royal CR441EHO a direct substitute for the DORMA 8656 EMR/TDE?
Not a straight one. The Cal-Royal CR441EHO is a Grade 1 door closer with an electronic hold-open track arm, so it covers the same basic idea of a closer that holds the door open electrically and releases it. The DORMA 8656 EMR/TDE is also Grade 1, but it is a holder/release unit with an integral photoelectric detector built in, which lets it sense smoke locally rather than relying only on a signal from a fire alarm panel. If the opening needs its own detector at the door, the 8656 EMR/TDE is the one that carries it; if the release signal comes from a central fire/smoke control system, an electronic hold-open track closer such as the CR441EHO addresses that part of the job.
7) I have a double egress pair in a hospital corridor - will a standard electronic hold-open track closer work?
A double egress pair is the case to watch. The DORMA 8656 EMR/TDE is built specifically for double egress applications and mounts on the pull side, with left hand and right hand versions so each leaf of the pair gets the correct unit. A general-purpose electronic hold-open track closer such as the Cal-Royal CR441EHO is a Grade 1 closer with an electronic hold-open track arm but is not designated for double egress, so on a double egress frame you would want the unit that is specified for that configuration.
8) Can I run the wiring on the surface, or does it have to be concealed in the frame?
Either. The EMF/EMR series is wired for concealed or surface wiring, so you can retrofit onto an existing frame without opening it up, and it interfaces with new or existing fire and smoke control systems. That is the usual reason this gets picked for a renovation rather than new construction.
9) What happens if someone pushes the door past the hold open point?
Nothing breaks. The series uses a patented hold open design that lets the door be manually pushed beyond the hold open point without damaging the door, frame, holder/release device, or the other hardware on the opening. In a corridor where carts and staff shove doors around all day, that is the detail that keeps these units from getting torn off.
10) If I do not need the built-in detector, is there a simpler option than the 8656 EMR/TDE?
Yes. The detector version exists so the door can sense smoke at the opening itself. Where the building already has a fire alarm panel that will drop power to the hold-open on alarm, a Grade 1 closer with an electronic hold-open track arm such as the Cal-Royal CR441EHO covers the hold and release function without the integral photoelectric detector. Keep in mind the 8656 EMR/TDE is handed and configured for double egress pull side mounting, so the two are only interchangeable on an opening that suits a standard closer.
11) Both are Grade 1 - what actually differs between the DORMA 8656 EMR/TDE and the Cal-Royal CR441EHO?
Both carry a Grade 1 rating. The DORMA 8656 EMR/TDE is a heavy duty commercial unit with a cam and roller track, closer sizes 5 to 6, electromagnetic hold/release with an integral detector, and a patented hold open design that lets the door be pulled manually past the hold open point without damaging the door, frame or hardware. The Cal-Royal CR441EHO is described as a Grade 1 closer with an electronic hold-open track arm. The practical split is the detector and the double egress pull side configuration on the DORMA unit.
12) We are standardizing corridor hold-opens across a facility - which unit fits which opening?
Split them by opening type. Double egress pairs on the pull side take the DORMA 8656 EMR/TDE, which is handed left or right and offered in 689 aluminum, 690 and 695 dark bronze, 691 light bronze, 693 black and 696 satin brass so it can match the rest of the corridor hardware. Single swing openings where the release signal comes from the alarm system can take a Grade 1 electronic hold-open track arm closer such as the Cal-Royal CR441EHO. Both are Grade 1, so the grade line on the spec stays consistent across the facility.
13) What finishes does the DORMA 8656 EMR/TDE come in?
Six: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze, and 696 satin brass. Every one is available in both left and right hand, so on a double egress pair you can match both leaves without changing finish.
14) Is this a residential product or strictly commercial?
Strictly commercial. The 8656 EMR/TDE is a heavy duty Grade 1 fire and life safety closer intended for commercial openings, typically corridor smoke barriers and cross-corridor pairs in healthcare, education, and multi-family buildings. It is not a residential door closer.
