ACSI ACSI-BB1279-4.5X4.5-10B-1104 – Frequently Asked Questions

1) What can the ACSI BB1279 electric through-wire hinge actually power on the door?
The through-wire is a concealed low voltage path from frame to door, with nothing running on the surface. ACSI lists the BB1279 for electrified mortise and cylindrical locks, exit devices with electric latch retraction, electric strikes on paired doors, and locks with monitoring or request-to-exit switches. A mortise lock plus a REX contact is a normal load for it. Match the conductor count to the number of circuits crossing the opening, since the hinge is built in 4 wire, 6 wire, and 8 wire versions.
2) Where in the hinge stack does the BB1279 electric hinge have to be installed?
Center position, and only the center. ACSI requires the electric hinge in the middle of the opening, which means the top and bottom hinges are ordinary non-electrified hinges you order separately. Lay out the wire path to suit: the frame gets bored at that middle hinge location, and the door edge runs from the same point to the lock or the exit device. Putting the through-wire hinge at the top and running conduit down the door is not how this one is set up.
3) How many wires do I need in a BB1279 through-wire hinge, 4, 6, or 8?
Count the circuits that have to cross the opening and allow a pair of conductors for each one. Power to an electrified lock is one pair. Latch or door position monitoring is another. A request-to-exit switch is another again. The BB1279 is built in 4 wire, 6 wire, and 8 wire, and every one of those is offered in both 4-1/2 x 4 and 4-1/2 x 4-1/2 and in all three finishes, so wire count does not restrict the rest of the order. Decide it up front: the pin is not field removable once ACSI has done the modification, so this is not something you change on site later.
4) Will the ACSI BB1279 electric hinge fit the hinge prep already in my hollow metal frame?
If the frame is cut for a 4-1/2 inch square corner hinge, it will. The BB1279 through-wire comes in 4-1/2 x 4 and 4-1/2 x 4-1/2 with square corners, which is the standard commercial hollow metal prep. Hinge sizes are given height first, then open width, so measure the existing mortise height and the open width to decide between the 4 inch and the 4-1/2 inch. The one thing your existing prep will not have is the wire hole: the through-wire needs a hole through the frame rabbet at the center hinge and a path in the door edge over to the lock.
5) Is the BB1279 through-wire hinge approved for a labeled fire door?
Fire rated openings are what the specification points to. The BB1279 is built to ANSI A8112 and complies with NFPA 80, and ACSI's 1100 Series electric hinges and pivots are UL Listed. It is a steel commercial hinge with two ball bearings, so it is the conventional full mortise hinge for that kind of opening rather than a specialty leaf.
6) What is the difference between a Hager 1279 hinge and the BB1279?
Bearings and wire. The Hager 1279 is a plain bearing medium duty full mortise commercial hinge with five knuckles and no electrical function at all. The BB1279 is the ball bearing version, two ball bearings, that ACSI has modified with a concealed electric through-wire so low voltage can pass from the frame into the door. If nothing on the door draws power, the plain 1279 is the simpler part to order. If the door carries an electrified lock, an electric latch retraction device, or monitoring contacts, the through-wire BB1279 is the one that gets the current across.
7) If the BB1279 electric hinge goes in the middle, what do I use for the top and bottom hinges?
Standard full mortise hinges cut to the same size and corner style. The through-wire hinge is 4-1/2 x 4 or 4-1/2 x 4-1/2 with square corners, so the other two positions have to match that prep. Don-Jo BB74545 is a standard duty steel full mortise ball bearing hinge at 4-1/2 x 4-1/2 with square corners and five knuckles, and McKinney TCA2314 is the same 4-1/2 x 4-1/2 square corner five knuckle pattern. For a 4-1/2 x 4 opening, Don-Jo BB74540 is that size in satin chrome. Order them in the finish that matches the electric hinge, which is offered in satin bronze blackened, oil rubbed dark bronze, and satin chrome.
8) The BB1279 through-wire hinge has to sit in the center position, so what goes at the top and bottom of the same door?
The ACSI BB1279 is specified for the center position only, which leaves the top and bottom leaves as ordinary non-electrified full mortise ball bearing hinges cut for the same prep. The Don-Jo BB74545 is a full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch steel with square corners and 5 knuckles, and the Don-Jo BB74540 covers the 4-1/2 inch by 4 inch size in satin chrome, so between them they match both sizes the BB1279 is built in and its square corner leaf. Pick the two outer leaves in the same finish family as the BB1279 center hinge and the opening reads the same from top to bottom.
9) The doors are already hung on McKinney TCA2314 hinges - will the BB1279 drop into that mortise?
The McKinney TCA2314 and TCA2317 are both square corner 5 knuckle full mortise hinges in 4-1/2 inch by 4-1/2 inch at a standard duty level, and the ACSI BB1279 is offered in that same 4-1/2 inch by 4-1/2 inch size with square corners as a standard weight steel full mortise hinge. What changes is the center leaf: the BB1279 carries the concealed through-wire, needs the wire routed out of the jamb, and its pin is not field removable once modified. Confirm the existing mortise depth and the wire path in the frame before swapping the center hinge.
10) How much current will the BB1279 through-wire hinge carry for a motorized latch retraction exit device?
Rated 3.5 amps continuous and 16 amps pulse, UL. That pulse headroom is why the hinge is used on exit devices with electric latch retraction, which draw a heavy inrush at the moment of retraction and settle to a much lower holding current. The same rating covers electrified mortise and cylindrical locks and electric strikes.
11) Can the pin be pulled on a BB1279 hinge once ACSI has run the wire through it?
No. The hinge pin is not field removable after the through-wire modification, so the hinge does not come apart on site the way a plain hinge does. ACSI also performs the modification on non-NRP hinges. Plan the install around that: set the frame leaf and the door leaf together rather than hanging the door on the barrel, and if pin security is called out on an outswing opening, put that requirement on the top and bottom hinges where the pin is still a normal one.
12) Does the ACSI BB1279 hinge come with screws for a hollow metal frame or for a wood door?
Both go in the box. It ships with 1/2 inch 12-24 machine screws for tapped hollow metal frames and doors, and 1-1/4 inch by 12 wood screws for wood doors and wood frames. So a hollow metal frame with a wood door, which is common on interior commercial openings, is covered from one carton with no separate fastener order.
13) Will a BB1279 hinge give me the extra clear width I need on an accessible opening?
It will not. The BB1279 is a conventional full mortise hinge and is not ADA compliant on its specification, so the leaf still sits inside the opening when the door swings and the clear width stays what it was. Recovering that width takes a swing clear hinge, which carries the door leaf out of the opening as it swings. ZenSupply carries the BEST CB248 steel full mortise concealed bearing swing clear hinge for square edge doors and the Hager 1260 full mortise swing clear hinge with a five knuckle plain bearing. Neither one has a through-wire in it, so an opening needing both clear width and power transfer gets the power across some other way.
14) My door has to swing clear of deep trim. Does the BB1279 electric hinge come in a wide throw?
The through-wire version is built in two sizes only, 4-1/2 x 4 and 4-1/2 x 4-1/2, so there is no wide throw leaf in it. Where the door needs to clear projecting trim, Hager WTBB1168 is a 4-1/2 x 6 full mortise ball bearing wide throw hinge, heavy weight with five knuckles, and it has no electrical function. An opening that needs both wide throw and power to the door has to move the transfer off the hinge.
15) The BB1279 is standard weight - what is the heavy weight equivalent for a solid core or lead-lined door?
The ACSI BB1279 is a standard weight steel full mortise hinge. For a heavier leaf, the McKinney TCA3386 is a heavy weight square corner 5 knuckle full mortise hinge in 4-1/2 inch by 4-1/2 inch, which matches the larger of the two BB1279 sizes and the square corner prep. The Stanley Security CB199 is another full mortise heavy weight option, built as a concealed bearing hinge in the Architectural Hinges series. Both are mechanical hinges without through-wire, so a door needing both heavy weight leaves and concealed power transfer is a two-part conversation with the hardware consultant.
16) The door has to clear deep trim when it swings back - the BB1279 sizes are too narrow, what else works?
The ACSI BB1279 is built in 4-1/2 inch by 4 inch and 4-1/2 inch by 4-1/2 inch, both of which keep the door close to the jamb. When the leaf has to throw further out to clear casing or a masonry return, the Hager WTBB1168 is a 4-1/2 inch by 6 inch full mortise ball bearing wide throw hinge, heavy weight with 5 knuckles. The extra leaf width is what buys the swing clearance; the WTBB1168 is a mechanical hinge and does not carry a wire.
17) Our openings are on an exterior wall near the coast - the BB1279 is steel, what holds up better to the salt air?
The ACSI BB1279 is a standard weight steel hinge. For a corrosion exposed opening, the Don-Jo BB94545 is a full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch stainless steel with a square corner, which matches the larger BB1279 size and corner prep, and the BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge for beveled edge doors. Neither one carries through-wire, so on a powered exterior opening the stainless leaves handle the top and bottom while the wire runs through the center hinge.
18) Is the ACSI BB1279 a genuine Hager hinge, and what has ACSI changed on it?
It starts life as a Hager BB1279, a full mortise ball bearing standard weight steel commercial hinge, and ACSI modifies it into a concealed electric through-wire hinge in its 1100 Series. The hinge body is the Hager part: steel, square corners, two ball bearings, 4-1/2 inch leaves. What ACSI adds is the concealed conductor run so the hinge can pass low voltage to hardware on the door, rated 3.5 amps continuous and 16 amps pulse. The modification is done on non-NRP hinges and the pin is not field removable afterward.
19) I am adding access control to a few doors in a building with satin chrome hinges. Will the BB1279 electric hinge match the rest?
Satin chrome is one of the three finishes offered, listed as 626. The other two are 10A satin bronze blackened and 10B oil rubbed dark bronze, and all three are built in both 4-1/2 x 4 and 4-1/2 x 4-1/2 and in 4, 6, and 8 wire. Because the wire run is concealed inside the hinge, the modified unit reads like the others down the corridor: same square corners, same button tip on the pin. Only the center hinge on each electrified door changes.
20) The architect wants the bearings hidden in the knuckle - how does that compare to the BB1279?
The ACSI BB1279 is a ball bearing hinge with two ball bearings, which read as separate bearing races in the knuckle stack. Concealed bearing hinges put the bearing inside the knuckle instead: the Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge at a medium duty level in the Architectural Hinges series, matching the BB1279 on weight class, and the BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin. Both are mechanical hinges, so the center leaf carrying the through-wire is still the ball bearing BB1279.
21) The rest of the hardware on the job is brass - is there a brass hinge that matches the satin chrome BB1279?
The ACSI BB1279 is offered in 626 satin chrome along with 10A satin bronze blackened and 10B oil rubbed dark bronze, all over a steel hinge. The Don-Jo BB84545 is a full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch brass finished in satin chrome, so it puts a brass base metal under the same satin chrome appearance at the size the BB1279 also comes in. That gives a consistent look across the opening when the specification calls for brass on the non-powered leaves.
22) Can I use the Hager 1541 in place of the BB1279 on an apartment entry door?
The Hager 1541 is a full mortise residential hinge with stainless steel construction, a 5 knuckle design and a plain bearing. The ACSI BB1279 is built for commercial openings, ball bearing rather than plain bearing, and it complies with NFPA80 under ANSI A8112. On a fire rated or high traffic entry the two are answering different requirements, so check what the door schedule calls for before treating the 1541 as a stand-in.
