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-EMF-PT-689 – Frequently Asked Questions

1) Will the DORMA 8656 EMF/PT hold my fire door open and release it when the alarm goes off?
That's exactly what the 8656 EMF/PT does. It's an electromagnetic hold-open track closer: the magnet holds the door open while energized, and when the fire/smoke control system signals an alarm state, or main power drops, current to the magnet is cut and the integral closer takes over and shuts the door. Note the /PT designation, this unit has no built-in photoelectric detector, so it has to be wired to a fire alarm panel or smoke control system to get its release signal. If you want a self-contained unit that senses smoke at the door itself, that's the detector-equipped EMR model, and one EMR can control an EMF unit on the other leaf of a pair.
2) Does the 8656 EMF/PT closer need to be ordered handed?
Handing matters on this one. The closer body itself is non-handed, but the 8656 EMF/PT is ordered with a hold-open track specified right hand or left hand, so you pick RH or LH when you order. Stand outside the door on the side it swings away from: if the hinges are on your right it's right hand. Get it wrong and the track and magnet land on the wrong end of the opening.
3) Is the 8656 EMF hold-open closer mounted on the pull side or the push side of the door?
Push side, surface mounted. The 8656 EMF/PT mounts on the face of the door on the side the door swings toward you when you pull, with the track surface-applied to the frame face above the opening. If the only clear surface on your opening is the pull side, or the frame face is obstructed by a soffit or transom, this mounting won't work and you need a pull-side configuration instead.
4) What size door will a DORMA 8656 EMF closer handle?
The 8656 EMF is a size 5 to 6 closer, heavy duty, which covers wide and heavy commercial openings, the upper end of the standard closer sizing range. If you're working on a genuinely oversized or high-traffic exterior leaf and want more closing power efficiency, the TS93 in Contur Design is the cam and roller model in the same EMF/EMR family and is the one used on larger doors. The 8900 in that family is the choice when you need a narrow projection off the door face for less cost.
5) Is the DORMA 8656 EMF/PT ANSI Grade 1?
Grade 1, and the EMF/EMR holder/release devices are ANSI/BHMA certified. Grade 1 is the highest ANSI/BHMA performance tier and the one most institutional and government specs call for on commercial openings. Paired with the heavy duty rating and size 5 to 6 range, it meets the usual spec language for a Grade 1 surface closer with electromagnetic hold-open on a fire or smoke barrier door.
6) Can I use the 8656 EMF hold-open closer with the fire alarm system already in the building?
Yes. The EMF/EMR Series interfaces with new or existing fire and smoke control systems, so you don't have to replace the panel to add hold-opens. It can be wired concealed through the frame or surface run, whichever the building allows. On a retrofit into an existing frame with no raceway, the surface wiring option is what keeps it from becoming a frame replacement job. The 8656 EMF/PT has no detector of its own, so the panel is what supplies its release signal.
7) Does the 8656 EMF/PT closer meet ADA opening force requirements?
No. The 8656 EMF/PT is not ADA compliant, and that follows from what it is: a size 5 to 6 heavy duty closer produces more opening force than an accessible route allows. If the opening is on an accessible route and has to meet the reduced opening force, you need a lower-powered or power-assisted arrangement instead. Where this unit belongs is a fire or smoke barrier door that is normally held open, so it is standing open under everyday use and only closes on alarm.
8) What is an equivalent to the DORMA 8656 EMF/PT if I need an electric hold-open closer from a different manufacturer?
The Cal-Royal CR441EHO is a Grade 1 door closer with an electronic hold-open track arm, which puts it in the same category of work as the DORMA 8656 EMF/PT: a surface closer with an integral electromagnetic holder that releases the door on an alarm or power interruption. The 8656 EMF/PT is also Grade 1, non-handed as a body with left and right hand specified at order, push side mounted, and uses a rack and pinion track. Both are track-arm electric hold-open closers, so the opening prep is comparable; confirm mounting side and track length against your frame before ordering either.
9) I need a hold-open closer that detects smoke at the door itself. Is the 8656 EMF/PT or the Cal-Royal CR441EHO the right one?
Neither one. Both the DORMA 8656 EMF/PT and the Cal-Royal CR441EHO are electric hold-open closers that take their release signal from somewhere else. The 8656 EMF/PT is the EMF version, meaning it holds and releases on a signal from a fire or smoke control system and does not carry its own detector; within the same family, the EMR version is the one that incorporates a photoelectric detector, and a single EMR can control one EMF unit on a pair of doors. If the door needs to release on its own local smoke sensing, specify the EMR; if the building already has a central alarm panel to wire into, the EMF/PT or the CR441EHO both work off that signal.
10) What happens if somebody yanks a door open past the magnet on a DORMA EMF hold-open closer?
Nothing breaks. The EMF/EMR Series uses a patented hold open design that lets the door be pulled manually past the hold open point without damaging the door, the frame, the holder/release unit, or the rest of the hardware on the opening. That's the failure mode that kills ordinary hold-open arms in apartment corridors and hospital wings, where the door gets forced past the stop by a cart or a resident. For a property manager standardizing corridor doors, that is the practical difference between a device you replace every year and one you don't.
11) How do I hold open both leaves of a pair of doors with the DORMA EMF series?
On a pair, run one detector-equipped EMR unit on one leaf and an 8656 EMF unit on the other: the EMR can control one EMF unit for a pair of doors, so a single smoke detection point releases both leaves together. If the building already has a fire alarm panel driving the hold-opens, you can instead use an EMF unit on each leaf and let the panel drop both. Order each leaf handed to its own swing, one RH and one LH on a normal pair.
12) Is the 8656 EMF a rack and pinion closer or a cam action closer?
Rack and pinion, with a rack and pinion hold-open track. That's the conventional closer mechanism, and in the EMF/EMR family the 8600 is the value-engineered choice. The cam and roller alternative in the same family is the TS93 in Contur Design, which is the more efficient mechanism and the one specified on larger doors. If your spec calls out cam action specifically, the 8656 is not the model that satisfies it.
13) Is there another Grade 1 electric hold-open track closer besides the DORMA 8656 EMF?
The Cal-Royal CR441EHO is the cross-brand alternative, a Grade 1 door closer with an electronic hold-open track arm, so it fills the same role: closer plus electrically released hold-open on the track. Where the 8656 EMF/PT differs is that it sits in DORMA's EMF/EMR fire and life safety family, which lets you pair it with a detector-equipped EMR unit on the other leaf and use the patented hold open design that tolerates the door being forced past the hold point. If you're matching existing DORMA hardware in the building, stay with the 8656.
14) Is the Cal-Royal CR441EHO strong enough for the same doors as the DORMA 8656 EMF/PT?
Both are Grade 1 closers, so they meet the same ANSI/BHMA grade tier. The DORMA 8656 EMF/PT is rated heavy duty for commercial openings and covers closer sizes 5 to 6, which is the range for wide and heavy doors. If your opening needs a size 5 or 6 spring, match that sizing explicitly when cross-shopping the CR441EHO, since grade alone does not tell you the spring size a given closer covers.
15) Can I use a plain Grade 1 surface closer instead of the DORMA 8656 EMF/PT to save on the electrical work?
Only if the opening does not need to hold open and release on alarm. The DORMA 8656 EMF/PT is an electronic unit whose electromagnetic hold open drops out when the central control system signals an alarm or main power fails, letting the closing mechanism shut the door. A non-electrified closer will close the door but gives you no held-open condition and no release event to tie into the fire and smoke control system. If the specification calls for a held-open door on a fire or smoke barrier, the substitute has to be electrified as well; the Cal-Royal CR441EHO is the Grade 1 electronic hold-open track arm closer in the comparable set.
16) What finishes does the DORMA 8656 EMF/PT come in?
Six finishes on the 8656 EMF/PT: 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 is the usual match to clear anodized aluminum frames and 690 or 695 to a dark bronze frame. The track and closer body carry the finish, so specify the same code across every opening in the run if you want them to read as a set.
17) Can I put a DORMA 8656 EMF/PT on an interior residential door?
It's built for commercial service, not residential. The 8656 EMF/PT is a heavy duty, size 5 to 6 commercial closer intended for fire and life safety openings that are held open and released on alarm. On a house door it's oversized, and there's nothing on a residential job to supply the release signal since this model carries no detector of its own. Multi-family corridor and stair doors are a different story, that's squarely commercial work and where these belong.
18) We standardize finishes across a building. Does the CR441EHO cover the same finish range as the DORMA 8656 EMF/PT?
The DORMA 8656 EMF/PT is offered in 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze, and 696 satin brass, which is a wide enough range to match most existing closer and track hardware in a commercial building. The Cal-Royal CR441EHO is a Grade 1 electronic hold-open track arm closer; if you are mixing brands across a facility, confirm the exact finish code on the Cal-Royal unit against the DORMA code rather than matching by name, since two products can both be called dark bronze and not sit at the same code.
