ACSI FBB179-4.5X4.5-26D-1104 – Frequently Asked Questions

1) Will the ACSI FBB179 electric hinge power an electrified mortise lock or electric latch retraction device?
That is what the FBB179 is built for. It transfers low voltage through the hinge barrel to electrified mortise locks, cylindrical locks, electric strikes, and exit devices needing electronic latch retraction or REX signaling, with no exposed wire between frame and door. UL rating on the transfer is 3.5A continuous and 16A pulse, so it covers both the holding current of a lock and the inrush of a motorized latch retraction device. It also supports concealed monitoring and combined power-plus-monitoring runs.
2) Should I order the 4 wire or the 8 wire version of the FBB179 hinge?
Count the circuits the opening needs before you order. The FBB179 comes in a 4 wire and an 8 wire build. Four conductors handle a single job, typically power to an electrified lock or a strike. Eight conductors give you room for power plus a second circuit on the same hinge, which is what door position monitoring, latch monitoring, or a REX return needs alongside the lock power. Both wire counts are offered in all four finishes: 10A satin bronze blackened, 613 satin bronze oil rubbed, 626 satin chrome, and 600 primed for painting.
3) What size is the ACSI FBB179 hinge and will it drop into my existing 4-1/2 inch hinge prep?
The FBB179 is a 4-1/2 by 4-1/2 inch full mortise hinge with square corners and five knuckles, which is the standard commercial hollow metal prep. If your existing door and frame are cut for a 4-1/2 x 4-1/2 square corner mortise hinge, the plate footprint matches. The electrification is the part that is not drop-in: the wire exits the hinge barrel and needs a raceway or wire path drilled through the door edge and the frame at that hinge location, so the door and frame have to be prepped for through-wire even though the mortise itself is not changing.
4) How many electric hinges do I need per door, and what about the other hinges?
One. Only a single FBB179 carries the wiring on a given opening, normally the top hinge or the center hinge, and the rest of the door hangs on plain hinges of the same size and finish. So a three hinge opening takes one FBB179 plus two matching non-electric 4-1/2 x 4-1/2 square corner ball bearing hinges. Don-Jo BB74545 in steel, BB94545 in stainless, or the McKinney TCA2314 all come in that same 4-1/2 x 4-1/2 square corner five knuckle size for the remaining leaves.
5) Can the FBB179 electric hinge be used on a fire rated door?
Yes, in the steel and stainless finishes. The FBB179 is UL Listed and UL fire rated for steel and stainless constructions. The brass based finishes are not carried under that fire rating, so on a labeled opening specify a steel or stainless finish rather than a brass one.
6) Is the ACSI FBB179 hinge ADA compliant?
No. The FBB179 is not ADA compliant. If the opening has to meet ADA clearance, a standard full mortise hinge like this one does not gain you the extra clear width, and a swing clear hinge is the type that does by swinging the door leaf fully out of the opening. The BEST CB248 and the Hager 1260 are swing clear full mortise hinges. Note that neither of those transfers power, so on an access controlled ADA opening you would pair a swing clear hinge with a separate electric power transfer device rather than an electrified hinge.
7) Can I use the McKinney TCA2314 or TCA2317 in place of the ACSI FBB179?
The McKinney TCA2314 and TCA2317 are both square corner, 5-knuckle full mortise hinges in 4-1/2 by 4-1/2, standard duty, so they match the ACSI FBB179 on leaf size, corner and knuckle count and will drop into the same mortise prep. What they do not do is pass current: the FBB179 is the electrified hinge in the set, carrying concealed low voltage power transfer, monitoring, or both through the barrel for electrified locks, strikes and REX. On a three-hinge access control door the usual build is standard hinges at two positions and the FBB179 at the one carrying the wire.
8) Which hinge should I use for a heavy traffic door instead of the ACSI FBB179?
The McKinney TCA3386 is a square corner, 5-knuckle full mortise hinge in 4-1/2 by 4-1/2, rated heavy weight and heavy duty, which suits high-cycle and heavy-leaf openings. The Stanley Security CB199 is another heavy duty full mortise option, built with concealed bearings rather than exposed ball bearings. Neither carries wiring, so if the door has an electrified lock the ACSI FBB179 is the one that both hangs the door and passes low voltage current concealed through the hinge.
9) Can the pin be removed from the FBB179 hinge for security, or to take the door down?
The pin is non-removable and tamper resistant, so nobody pulls the hinge pin from the secure side to lift the door off. That matters on out-swinging exterior and stairwell doors where the barrel is exposed. The trade off is service: you cannot drop the door by driving the pins, so a door removal means unscrewing the leaves, and the through-wire has to be disconnected before the door comes off. If you want a hinge you can pin out for maintenance, the BEST 1900R is a full mortise hinge with a removable pin, though it carries no wiring.
10) What is the difference between a ball bearing hinge like the FBB179 and a plain bearing hinge?
Bearing type tracks traffic. The FBB179 uses ball bearings between the knuckles, which carry heavier door weight and high cycle counts without the knuckles galling, and it is specified for commercial use. Plain bearing hinges have no bearings in the joint and are for lighter, lower traffic openings: the Hager 1279 is a medium duty plain bearing commercial hinge and the Hager 1541 is a plain bearing residential hinge. On any access controlled door the hinge is cycling constantly and carrying a lock, closer and wiring, so ball bearing is the right call.
11) I need to match the FBB179 to the finish on my other hinges. What finishes does it come in?
Four finishes are made: 10A satin bronze blackened, 613 satin bronze oil rubbed, 626 satin chrome, and 600 primed for painting. The 600 prime coat is the one for painted hollow metal openings where the hinges get finished to match the frame. 626 satin chrome is the usual match on commercial stainless and aluminum trim, and both Don-Jo BB74540 and Don-Jo BB84545 are offered in satin chrome if you need matching non-electric leaves on the same door.
12) Does the FBB179 hinge work with fail safe and fail secure locks?
Either. The FBB179 is a power transfer path, not a lock, so it simply carries the low voltage across the opening and is stated as compatible with monitoring and with fail safe or fail secure operation. Whether the door locks or unlocks on power loss is decided by the lock or strike you feed through it, not by the hinge. The same hinge serves a fail safe stairwell lock and a fail secure entry lock.
13) Is the ACSI FBB179 the same thing as a CEFBB179 hinge, and does it meet a spec calling for a Stanley FBB179?
Same part. The FBB179 is sold against specifications written for FBB179 hinges, CEFBB179, and the Stanley FBB179 electric through-wire hinge, and the model is carried under the ACSI name. CE in the CEFBB179 designation is the concealed electric prefix on the same 4-1/2 x 4-1/2 five knuckle ball bearing body. If the drawing calls out a concealed electric FBB179, this is the hinge that answers it.
14) My door is heavy and out of plumb. Is a wide throw or pivot reinforced hinge a better choice than the FBB179?
They solve different problems, and the FBB179 does not solve those two. A wide throw hinge sets the door further off the frame to clear deep trim or brick mold, and that is the Hager WTBB1168 at 4-1/2 by 6 inches, heavy weight. Pivot reinforced hinges carry heavy door weight at the top: the BEST FBB212 covers square edge doors and the BEST CB223 covers beveled edge doors. None of those transfer power. If the opening needs both, hang the door on the heavy hinges it requires and use the FBB179 as the one electrified leaf, or move the power transfer off the hinge entirely.
15) Is a ball bearing hinge like the Hager 1279 the same thing as the ACSI FBB179?
No. The Hager 1279 is a full mortise commercial hinge with 5 knuckles and a plain bearing design in medium duty, and the Hager 1541 is a plain bearing stainless steel 5-knuckle residential hinge. Plain bearing hinges have no bearing races between the knuckles. The ACSI FBB179 is a ball bearing hinge, which is the type usually called for on doors with closers or continuous traffic, and it additionally carries concealed low voltage wiring through the hinge for access control. A plain bearing hinge will not substitute where the specification calls for bearing hinges or for electric through-wire.
16) What is the difference between the ACSI FBB179 and the BEST CB1960R or 1900R?
The BEST CB1960R is a full mortise concealed bearing standard weight hinge in medium duty, and the BEST 1900R is a steel full mortise concealed bearing standard weight hinge, also medium duty, with a removable pin. The ACSI FBB179 differs in three ways that matter on an access controlled door: it uses ball bearings rather than concealed bearings, its pin is non-removable for tamper resistance, and it carries concealed low voltage power transfer and monitoring wiring through the hinge. On a secure opening the removable pin of the 1900R is the detail to check before substituting.
17) I need a satin chrome ball bearing hinge to match the ACSI FBB179 on the other doors of the same frame set.
The Don-Jo BB84545 is a full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch, brass, in satin chrome, and the Don-Jo BB74540 is a full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch by 4 inch, also satin chrome; both are standard duty. The ACSI FBB179 is offered in a 626 satin chrome finish, so the non-electrified leaves on the same opening or the adjacent doors can be matched while only the hinge carrying the wiring is the electrified one.
18) What hinge handles a beveled edge door or one that needs extra throw, since the ACSI FBB179 is a 4-1/2 by 4-1/2 square corner hinge?
The BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge made for beveled edge doors, in heavy duty. Where the door has to swing clear of a deep trim or return wall, 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 ACSI FBB179 is built as a 4-1/2 inch by 4-1/2 inch square corner hinge, so on a beveled edge or wide throw condition the power transfer has to be planned around one of these leaf geometries.
19) Is there a stainless steel hinge comparable to the ACSI FBB179 for a corrosive or wash-down area?
The Don-Jo BB94545 is a full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch, stainless steel with a square corner, in standard duty. The ACSI FBB179 is built in heavy-duty stainless or brass depending on finish and is UL Listed and UL fire rated in the steel and stainless finishes, so where the opening is both a wet or corrosive environment and an access controlled door, the FBB179 covers the electrification while the BB94545 can hang the remaining leaf positions in matching stainless.
20) The spec calls for a pivot reinforced hinge - how does the BEST FBB212 relate to the ACSI FBB179?
The part numbers look close but the hinges are different types. The BEST FBB212 is a steel ball bearing heavy weight pivot reinforced hinge for square edge doors, in standard duty, where the pivot reinforcement carries the door load at the top. The ACSI FBB179 is a 5-knuckle ball bearing full mortise hinge with concealed electric through-wire, used where low voltage has to reach an electrified lock or strike. Ordering by the FBB prefix alone will get you the wrong item; confirm whether the drawing wants pivot reinforcement or power transfer.
21) I need to standardize the electrified openings across my building. Does the FBB179 work as a fleet standard?
It does the job a facility standard has to do: one hinge model, one 4-1/2 x 4-1/2 square corner prep, four finishes, and a choice of 4 or 8 conductors depending on whether that opening needs power only or power plus monitoring. Because it is a commercial ball bearing hinge with a non-removable pin and UL Listing, the same part number covers interior access controlled doors and exposed exterior ones. Order the 8 wire on any door you might later add monitoring or REX to, so the hinge does not have to be changed when the head end gets expanded.
