Professional Door Sequencing Solution for Fire-Rated Applications

The ABH 3700 Series Full Bar Door Coordinator ensures proper door sequencing on paired doors where one door must close before the other. This UL Listed coordinator features an active door lever that holds the active door open until the inactive door closes enough to trip the release mechanism, then allows the active door to close. The included filler bar provides a virtually seamless appearance across the entire soffit, while the safety override allows the active door to close first when extreme force is applied.

ABH 3711 US28 – Frequently Asked Questions

1) How do I pick the right ABH 3700 coordinator size for my pair of doors?
Size is chosen by the total door opening width. The 3711 covers openings 52 inches or less, the 3712 covers 52-1/16 to 56 inches, and the 3721 covers 56-1/16 to 72 inches. Measure the full opening across both leaves, not one leaf, then order the model whose range it falls in. All three ship in Satin Aluminum.
2) Can the ABH 3700 coordinator be used on a fire rated pair of doors?
Yes, it is UL Listed for paired swinging fire doors that incorporate an astragal, up to and including 3 hours of fire protection. The astragal is the condition to watch: a coordinator is required on a fire pair precisely because the astragal means the inactive leaf has to close first, and this device is listed for that assembly.
3) Do I need a door coordinator on my pair of doors, or just closers?
You need a coordinator any time the inactive leaf must close before the active leaf, which is the case on any pair with an astragal or an overlapping edge, and on fire pairs with a mortise or vertical rod device on the inactive door. Closers alone will race and leave the pair latched open or jammed. The 3700 Series handles that sequencing with an active door lever that holds the active leaf open until the inactive leaf closes far enough to trip the release.
4) What else do I have to order with an ABH 3700 coordinator if I have stop mounted hardware?
Stop mounted hardware needs mounting brackets. The 3700 Series works with the 3751 and 3752 brackets, which carry the stop mounted device clear of the coordinator bar. If your closers and holders are all soffit or frame mounted, you do not need them.
5) What is the closest equivalent to an ABH 3700 coordinator if I need an aluminum bar coordinator from a different manufacturer?
The Ives COR Series aluminum bar door coordinators are the closest like-for-like alternative. Both are bar-type coordinators for paired openings and both are UL Listed and fire rated, so either can sequence a pair of fire doors with an astragal. The ABH 3700 comes in three bar lengths keyed to the opening - 3711 for openings 52 inches or less, 3712 for 52-1/16 to 56 inches, and 3721 for 56-1/16 to 72 inches - and ships with a filler bar for a continuous appearance across the soffit. Measure the full opening width before selecting either one.
6) The soffit on my pair is too narrow for a full bar coordinator - what coordinator can I use instead?
Where a bar spanning the soffit will not work, a gravity coordinator or an arm-type coordinator is the usual substitute. The Ives COR7G and COR9G are brass gravity coordinators with field-adjustable operation, and the Trimco 3092 is a UL retracting arm coordinator - neither carries a bar across the head of the opening the way the ABH 3700 does. The ABH 3700 is a full bar coordinator supplied with a filler bar to span the entire soffit, so it needs a clear continuous soffit across the pair.
7) I am using stop mounted hardware on a fire pair - does the ABH 3700 work or do I need a stop mounted coordinator?
The ABH 3700 handles stop mounted hardware through mounting brackets 3751 and 3752, which adapt the bar coordinator to that configuration. If you would rather use a coordinator designed as stop mounted from the start, the Trimco 3094 is a UL stop mounted coordinator. Both routes are suited to fire-rated pairs - the ABH 3700 is UL Listed for paired swinging fire doors incorporating an astragal up to and including 3 hours.
8) What happens if someone forces the active door shut first on a bar coordinator?
The 3700 Series has a safety override built in, so the active leaf can close first when extreme force is applied rather than the arm or the door taking the damage. That matters in egress traffic, where you cannot count on people respecting the sequence.
9) Will a bar coordinator look bad across the soffit of the frame?
The 3700 Series is supplied with a filler bar that runs the rest of the soffit, so the assembly reads as one continuous bar across the full opening instead of a short device sitting off to one side. Finish is US28 Satin Aluminum, which is paint ready if you need it to disappear into a painted frame; custom finishes are available from the factory.
10) Bar coordinator or gravity coordinator, which should I use?
A full bar type like the ABH 3700 mounts across the soffit of the frame and coordinates the whole opening from above, which is the usual choice on standard commercial pairs. A gravity type such as the Ives COR7G/COR9G, which is brass with field adjustable operation, is a different mounting approach for the same sequencing job. Both are fire rated options. Pick the bar type where you have soffit depth to mount to and want the continuous look; pick the gravity type where the arm geometry suits the opening better.
11) What else does ZenSupply carry if I need a fire rated door coordinator other than the ABH 3700?
Three close alternatives. The Ives COR Series aluminum bar coordinators are the direct like for like, aluminum bar type and UL Listed fire rated. The Trimco 3092 is a UL retracting arm coordinator, a different mechanism that pulls back rather than sitting as a bar. The Trimco 3094 is a UL stop mounted coordinator, which is the one to look at when your mounting condition is the stop rather than the soffit.
12) My opening is wider than 72 inches, will an ABH 3700 coordinator work?
No. The 3700 Series tops out at the 3721, which covers 56-1/16 to 72 inches of door opening. Anything wider is outside the range of all three models and you need a different coordinator sized for that opening.
13) Is a gravity coordinator the same thing as a bar coordinator?
They are different mechanisms for the same job. The ABH 3700 is a bar coordinator: an active door lever holds the active door open until the inactive door closes far enough to trip the release mechanism. The Ives COR7G and COR9G are brass gravity coordinators, and their operation is field-adjustable after installation. If the sequencing on a gravity unit is what you want to be able to tune on site, the COR7G/COR9G is the one built for that; the ABH 3700 instead includes a safety override that lets the active door close first when extreme force is applied.
14) Which coordinators besides the ABH 3700 are approved for fire-rated pairs?
Among the common alternatives, the Ives COR Series aluminum bar coordinators and the Ives COR7G/COR9G gravity coordinators are both fire rated, and Trimco's 3092 retracting arm and 3094 stop mounted coordinators are both UL units. The ABH 3700 is UL Listed for paired swinging fire doors incorporating an astragal for up to and including 3 hours of fire protection. Confirm the rating your opening carries against the coordinator's listing before you order, since a coordinator on a fire pair is part of the rated assembly.
15) What should I use on a pair wider than 72 inches?
The ABH 3700 bar coordinators cover openings up to 72 inches, with the 3721 model sized for 56-1/16 to 72 inches. Past that width, look at the Ives COR Series aluminum bar coordinators, which are offered in a range of bar sizes, or at a mechanism that does not span the opening at all, such as the Trimco 3092 retracting arm coordinator. Measure the finished opening width, not the leaf width, when you size any of them.
16) Can a door closer or a stop replace a coordinator on a pair of fire doors?
No - those solve a different problem. A coordinator exists to sequence the leaves so the inactive door closes before the active one, which is what lets an astragal-equipped fire pair latch properly. The ABH 3700 does this with an active door lever that holds the active door open until the inactive door closes enough to trip the release mechanism. If the ABH 3700 does not fit your opening, the substitute is another coordinator - the Ives COR Series aluminum bar units, the Ives COR7G/COR9G gravity units, or Trimco's 3092 retracting arm or 3094 stop mounted coordinators.
17) Is the ABH 3700 coordinator suitable for a school or hospital corridor pair?
It is a commercial rated device, and the applications it is built for include educational and healthcare facilities, government buildings, offices, multi-tenant residential and industrial sites. The 3-hour UL Listing covers the fire rated corridor and stair pairs those facilities standardize on. For a facility standard, the model changes only with opening width, so you can spec one series across the building and vary between the 3711, 3712 and 3721 by opening.
18) I want to match a brass or bronze finish on the pair - is the ABH 3700 the right choice?
The ABH 3700 is supplied in US28 satin aluminum ready to paint, with custom finishes available from the factory. If you would rather start from a brass body, the Ives COR7G and COR9G are brass gravity coordinators. Note that these are different mechanisms, so the choice affects more than appearance - the ABH 3700 is a full bar unit with a filler bar spanning the soffit, while the COR7G/COR9G is a gravity coordinator with field-adjustable operation.
