Command Access ETMM4540 626 CH-BB68 – Frequently Asked Questions

1) What does the Command Access ETM-BB68 hinge actually do that a regular ball bearing hinge doesn't?
Two things at once. The ETM-BB68 carries low-voltage power from the frame into the door through the hinge itself, so an electrified lock, electric latch retraction device, or electrified exit trim gets power with no visible loop cord or wire crossing the gap. It also has a built-in door position switch, so the same hinge reports whether the door is open or closed back to an access control or building management panel. On a conventional opening you would need a separate power transfer device and a separate DPS in the frame head; this consolidates both into one 5-knuckle heavy weight steel hinge that looks like the other hinges on the door.
2) I only need door position monitoring, no power to the lock. Can I still use the ETM-BB68?
Yes, order it as the M option, Monitor Only. That gives you the integrated door position switch in the hinge with no power transfer conductors, so the hinge reports door status to your access control panel while the lock stays mechanical. It's the option to use when you're adding door monitoring to an existing opening and the lockset isn't electrified.
3) What hinge sizes does the Command Access ETM-BB68 come in, and which one matches my existing hinge prep?
Four sizes: 4.5 x 4, 4.5 x 4.5, 4.5 x 5, and 5 x 5 inches. Match the size to what is already mortised into your frame and door edge, because a wire transfer hinge is a full mortise hinge and it has to drop into the existing cutout. Most commercial 1-3/4 inch doors on hollow metal frames are prepped for 4.5 x 4.5, so that's the size to check first. If the door is thicker or heavier and someone specified a wider leaf to clear trim, you'll see 4.5 x 5 or 5 x 5 on the frame.
4) Do I replace all three hinges on the door with the ETM-BB68, or just one?
Just one. The ETM-BB68 is the power transfer and monitoring point for the opening, so it goes in one position, typically the top or center hinge, and the remaining hinges on the door stay conventional. Match the size and finish of the ETM-BB68 to the other hinges so the opening looks uniform; the hinge is built to keep the visual appearance of a standard non-electrified hinge for that reason. If you need matching plain hinges for the other two positions in a 4-1/2 x 4-1/2 heavy weight, the Don-Jo HWBB74545 and the Ives 3CB1HW are both heavy duty options.
5) Is the ETM-BB68 heavy enough for a high-traffic exterior door with a closer and an electric strike?
It's rated heavy duty, with a 5-knuckle heavy weight design on a steel base, and it's meant for doors with frequent use carrying heavier hardware. That's the class you want on an entrance with a closer, an electrified lock, and constant cycling. Lighter medium duty electrified hinges exist, such as the BEST CECB179-12C, but they are a different duty class and are not the right choice under a heavy door and closer combination.
6) Is the Stanley CECB1900R54L an equivalent electrified hinge to the Command Access ETM-BB68?
They both carry power through the hinge, but they are built differently. The Stanley CECB1900R54L is a three knuckle concealed bearing concealed conductor architectural hinge, steel full mortise, standard weight, 4-1/2 by 4-1/2, square corner, left-handed, with 4 wires. The ETM-BB68 is a 5-knuckle heavy weight hinge with steel base construction and an integrated door position switch, and its wire options run from 2 wires up to 10 wires as well as monitor only. If the drawing calls for a specific hand and a fixed 4-wire standard weight hinge, the Stanley matches that; if the opening needs door status reported back to access control through the same hinge, the ETM-BB68 does that in one unit.
7) What is the closest alternative to the Command Access ETM-BB68 if the opening needs concealed wire transfer but not door position monitoring?
The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, so it carries low-voltage conductors through the hinge without the built-in monitor switch. The ETM-BB68 combines power transfer and a door position switch in one hinge, and it can also be ordered in a monitor-only wire option when the switch is all the opening needs. The CECB179-12C is rated medium duty, while the ETM-BB68 is a heavy duty 5-knuckle heavy weight hinge, so the two suit different door weights.
8) If an opening does not need any electrified hardware, what heavy duty hinge takes the place of the Command Access ETM-BB68?
Any non-powered heavy weight mortise hinge in the same size range will do. The Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, and the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge in 4-1/2 by 4-1/2. The ETM-BB68 is only worth specifying when the door has electrified hardware to feed or a door status signal to report, since that is what the concealed wire transfer and built-in monitor switch are for; it is offered in 4.5 x 4, 4.5 x 4.5, 4.5 x 5, and 5 x 5.
9) Which hinges look like substitutes for the Command Access ETM-BB68 but will not carry power to an electrified lock?
The 5-knuckle hinges that resemble it are the ones to watch. The McKinney MP79 MacPro full mortise hinge and the MPB79 MacPro hinge are both 5-knuckle standard weight, and the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge in 4.5 by 4.5 - none of them are electrified hinges. The ETM-BB68 looks the same from the face of the door by design, keeping the appearance of a conventional non-electrified hinge, but it is an electronic product with concealed low-voltage conductors and a monitor switch inside. If the door has an electric strike, electrified mortise lock, or latch retraction device fed through the hinge, a plain 5-knuckle hinge will not serve.
10) What finishes does the ETM-BB68 hinge come in so it matches the rest of my door hardware?
Ten finishes: 600 primed for painting, 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, 626 satin chrome, and 693 black. On most commercial openings you'll be matching 626 satin chrome, and 600 is there for frames that get painted out. Because the electrified hinge is meant to look like the standard hinges beside it, order it in the same finish code as the rest of the openings in the building.
11) Should I use an electrified hinge or a door loop for power transfer to an electrified lock?
A wire transfer hinge like the ETM-BB68 runs the conductors through the hinge barrel, so nothing is visible on the opening and there is nothing exposed for someone to cut or pull. A surface door loop is faster to add to a door that's already hung, but it's visible on the hinge edge and it's the part that gets damaged. Go with the hinge when the opening is high security, when the door is being prepped anyway in new construction, or when the frame already has the raceway. The ETM-BB68 has the added advantage that the door position switch is inside it, so you're not also cutting the frame head for a separate DPS.
12) Can the ETM-BB68 be retrofitted into an existing door, or is it new construction only?
Both. Command Access lists retrofit and new construction in controlled access environments as intended applications for the ETM-BB68. On a retrofit you still need a path for the wire: the frame has to be able to accept the conductors from the hinge back to the panel, and the door edge needs a route from the hinge to the electrified lock. The hinge itself drops into the existing full mortise prep if you order the matching size from the 4.5 x 4, 4.5 x 4.5, 4.5 x 5, and 5 x 5 range.
13) Will a standard residential or commercial hinge work if I just drill it for the wire instead of buying the ETM-BB68?
No. Hinges like the Deltana DSB45, the Emtek 94013 heavy duty ball bearing, or the Orca 3535 ball bearing commercial hinge are mechanical hinges with no conductor path through the barrel and no monitoring switch, and modifying one is not a substitute. The concealed conductors in the ETM-BB68 are routed and terminated as part of the hinge; that's what makes the transfer tamper resistant and what lets the door position switch report status. If you need power across the gap, you need a purpose-built electrified transfer device.
14) Do I still need a separate door contact if I install the ETM-BB68?
No. The door position switch is inside the ETM-BB68 hinge, and it connects straight to your access control or building management system to report whether the door is open or closed. That removes the frame-head magnetic contact from the job, which saves the frame prep and the second cable run. If you want the monitoring function without powering a lock, the M option gives you monitor only.
15) For a detention or high-security opening, is the Command Access ETM-BB68 the right hinge or should a prison hinge be used?
They solve different problems. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge and the Hager 990 STEEL is a full surface prison hinge, 3 by 4, with a welded tip - those are built for attack resistance at the hinge itself. The ETM-BB68 addresses security a different way: it is a heavy duty hinge whose low-voltage conductors run concealed inside, with no visible wires to cut or tamper with, and its monitor switch reports door status back to the access control or building management system. On a detention opening that also needs power at the door, the prison hinge handles the leaf and the ETM-BB68 handles the transfer and monitoring.
16) Can a residential ball bearing hinge be used in place of the Command Access ETM-BB68 on a light interior door?
Not if the door has electrified hardware. Hinges such as the Delaney 4 by 4 commercial ball bearing hinge with square corner, the Emtek 94013 heavy duty ball bearing hinges in 3-1/2 by 3-1/2 plated steel, and the Orca 4-1/2 by 4-1/2 square corner ball bearing commercial hinge are mechanical hinges with no conductors. The ETM-BB68 is a commercial heavy duty hinge intended for high-traffic and high-security openings where power has to reach a lock or latch through the hinge, and its smallest size is 4.5 by 4. On a light interior door with no powered hardware, the plain ball bearing hinges cover the swing; on a door with an electrified lock, they do not.
17) What should be used instead of the Command Access ETM-BB68 on a door hung on pivots?
A wire transfer hinge only works on a mortise-hinged opening. Where the door swings on pivots, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors and the BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge, both heavy duty. The ETM-BB68 is a full-size mortise hinge in 4.5 x 4, 4.5 x 4.5, 4.5 x 5, and 5 x 5 that needs matching hinge preps in the door and frame to carry its concealed conductors, so it is not a drop-in for a pivot-hung leaf.
18) The frame is prepped for a half mortise or full surface hinge - does the Command Access ETM-BB68 fit?
No. The ETM-BB68 is a full mortise style 5-knuckle heavy weight hinge that mounts into matching leaf preps in both the door and the frame. For a half mortise prep, the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2, standard weight steel; for a full surface application the Hager 990 STEEL is a full surface prison hinge, 3 by 4, with a welded tip. Those are mechanical hinges, so an opening with a half mortise or full surface prep that also needs power at the door will need the prep changed or a separate transfer device.
19) How does the Command Access ETM-BB68 compare to a medium duty concealed bearing hinge like the Ives 3CB1 for a high-traffic entry?
The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, as is the Hager 920, a full mortise concealed plain bearing hinge with 2-knuckle steel construction. The ETM-BB68 is heavy duty with a 5-knuckle heavy weight design and steel base construction, sized for doors with frequent usage and heavier hardware loads. On a high-traffic entry carrying an electrified lock and a closer, the knuckle count and duty rating of the ETM-BB68 line up with that load; a medium duty 3-knuckle hinge is scoped to lighter openings.
20) Is the ETM-BB68 suitable for a school, hospital, or government building access control system?
That's the intended use. Command Access lists the ETM-BB68 for commercial, institutional, and government facilities, specifically high-security and high-traffic openings, and it's built to ANSI standards on a steel base. For a facility standardizing across many openings, the practical advantage is that one part number covers both the power transfer and the door position monitoring, and it's available in ten finishes and four sizes so it can be specified to match hinge preps that already vary across a building.
21) Is a spring hinge or a security hinge with a non-removable pin an alternative to the Command Access ETM-BB68?
They answer different requirements. The Stanley 2060R is a heavy duty full mortise spring hinge, square corner, 4.5 by 4.5, ferrous steel base, for self-closing; the Deltana CSB45N is a 4-1/2 by 4-1/2 square hinge pair with a non-removable pin, and the Deltana DE44R5TA is a 4 by 4 security hinge with a 5/8 radius in steel. None of them transfer power. The ETM-BB68 is the choice when low-voltage power has to reach an electrified lock, latch, or exit trim through the hinge, or when the door needs a position switch feeding access control - self-closing or pin security would then be handled by other hinges in the same set or by a closer.
