BEST 9KM37DDEU14PHSTK626 – Frequently Asked Questions

1) Will the BEST 9KM IDH MAX prox lock work with our existing HID cards?
The 9KM IDH MAX reads HID proximity credentials, and also Motorola/Indala prox, with a 0 to 3 inch read range. If your badge population is already HID prox, the existing cards keep working. The read range means the card has to be presented at the lever, not waved from across the corridor.
2) What power supply do I need for a BEST 9KM IDH MAX cylindrical lock?
Plan on 10.2 to 13.2 VDC at the lock. Peak draw is 850 milliamps for 50 milliseconds at actuation, with a typical hold current of 550 milliamps. Size the supply for the inrush across every door on the circuit, not just the hold current, and account for voltage drop over the run so you are still above 10.2 VDC at the door.
3) How much wiring does the 9KM IDH MAX need compared to separate reader, door contact and REX?
One 4-conductor run to the door. The lock carries the prox reader, door position, request-to-exit and latch status monitoring inside the chassis, so you are not pulling separate cables for a surface reader, a recessed contact and a REX device. That is the main install-labor argument for this lock over a discrete component build.
4) Should I order the DDEL or DDEU version of the BEST 9KM?
DDEL is electrically locked: the lever is free until power is applied, so the door secures when the system energizes and it fails unlocked on power loss. DDEU is electrically unlocked: it is locked at rest and releases when energized, so it fails locked. Egress-critical and life-safety openings usually take fail-safe DDEL, while asset rooms, IT closets and exterior perimeter doors usually take DDEU so a power failure does not leave them open. Both are offered on the 9KM.
5) Can I still key-override a BEST 9KM IDH MAX if the access control system goes down?
Yes. The lock ships with SFIC prep less core, so it takes a small format interchangeable core for mechanical key override. The core is not included, which is deliberate: you drop in a core from your existing BEST SFIC keying system so the lock falls under the same master key hierarchy as the rest of the building. Order the core and key blanks separately.
6) What door prep does the BEST 9KM IDH MAX need, and what backsets are available?
It mounts in a modified ANSI A156.2 Series 4000 prep with a 2-1/8 inch diameter cross bore. Standard backset is 2-3/4 inches, with 3-3/4 inch and 5 inch backsets also offered for wider stiles and doors with deeper trim. Because the chassis is modified prep rather than standard 161 prep, budget for door machining or factory-prepped doors rather than assuming a straight swap into an existing bore.
7) Will the 9KM latch into the strike already in my frame?
The latch has a 9/16 inch throw and the standard strike is 2-3/4 by 1-1/8 inches with a curved lip, which matches common ANSI T-strike frame prep for cylindrical locks. An S3 strike, 4-7/8 by 1-1/4 inches with curved lip and box, is available for frames cut for the full ANSI 4-7/8 inch strike. With a 9/16 inch throw the frame gap matters, so verify your existing strike lip projection covers the jamb before reusing it.
8) Is the BEST 9KM IDH MAX fire rated, and can I use it on a labeled door?
It is UL listed for 3-hour A label single doors up to 4 feet by 10 feet, in both US and Canadian applications. That covers most labeled stairwell and corridor openings. The fire listing applies to single doors at those dimensions, so pairs and oversized leaves need to be verified against the opening's own label.
9) What is the closest alternative to the BEST 9KM IDH MAX proximity lock if I need a stand-alone opening instead of one wired back to a panel?
Look at the Dormakaba E-Plex 5270 stand-alone access controller, also a Grade 1 device. The difference is in how the opening is fed: the BEST 9KM IDH MAX runs on 10.2 to 13.2 VDC and is electrically locked (DDEL) or electrically unlocked (DDEU), so it expects a power run and control wiring back to the system. The E-Plex 5270 is built as a stand-alone controller for the door. If your opening has no power path and you cannot pull a wire run, the E-Plex is the direction to go; if you want latch status, door status and request-to-exit reported back over a single 4-conductor run, the 9KM IDH MAX is the one that carries those signals.
10) Does the Dormakaba E-Plex 5270 take HID proximity cards the same way the BEST 9KM does?
Do not assume so. The BEST 9KM IDH MAX is specifically a proximity reader lock, compatible with HID and Motorola/Indala proximity credentials at a 0 to 3 inch read range, with the reader built into the lock itself. The E-Plex 5270 is catalogued as a stand-alone access controller in the E-Plex 5X70 series without a stated proximity credential type. If your site is already issuing HID prox cards and you need the new opening to read those same badges, the 9KM IDH MAX is the one specified around that credential.
11) I need a keyed mechanical override on the door. How do the BEST 9KM IDH MAX and the Dormakaba E-Plex 5270 compare there?
The BEST 9KM IDH MAX ships SFIC prep less core, so it accepts a small format interchangeable core and drops straight into a site already keyed on SFIC - the locksmith supplies the core and it keys to the existing system. The E-Plex 5270 is a Grade 1 stand-alone access controller in the 5X70 series; it is not sold as an SFIC-prepped lock chassis. For a facility standardized on interchangeable cores with a master key system already in place, the 9KM IDH MAX is the one that matches that keying program.
12) For a 3-hour A label fire door, can I substitute the Dormakaba E-Plex 5270 for the BEST 9KM IDH MAX?
Verify the fire listing before you do. The BEST 9KM IDH MAX is UL listed for 3-hour A label single doors up to 4 feet by 10 feet for both U.S. and Canadian applications, which is the claim a fire door inspector will want to see. The E-Plex 5270 is described as a Grade 1 stand-alone access controller without a stated fire label. On a rated opening where the inspection is the gate, the 9KM IDH MAX is the unit carrying the 3-hour A label listing.
13) Do I have to specify handing when ordering a 9KM IDH MAX lock?
No. The 9KM is non-handed, so one part number covers left and right hand openings and you can stock a single spare for a whole building. You do still choose lever style, three options: contour with angle return, curved with return, and curved without return.
14) Is the BEST 9KM tough enough for a high traffic entrance or a hospital corridor?
The chassis is ANSI/BHMA A156.2 Series 4000 Grade 1, which is the heavy duty commercial classification, with brass, zinc and corrosion-treated steel internals. For infection-control environments there is a 626AM satin chrome antimicrobial finish alongside the standard 626 satin chrome, which is the usual pick for healthcare and education corridors.
15) Can the 9KM IDH MAX go on an exterior door?
Yes. It comes with a weatherproof bezel and gasket for exterior and outdoor openings in most environmental conditions. For an exterior perimeter door most integrators pair that with the DDEU electrically unlocked function so the opening stays secure if power drops.
16) How is the BEST 9KM IDH MAX different from a stand-alone controller like the Dormakaba E-Plex 5270?
Two different architectures. The 9KM is a wired lock that reports latch status, door position and request-to-exit back to a head-end access control panel over one 4-conductor run, so it belongs on a managed, monitored system. The Dormakaba E-Plex 5270 is a stand-alone access controller in the E-Plex 5X70 Series, also Grade 1, which is what you use where there is no panel and no wire to pull. Choose the 9KM when you need real-time door monitoring and central credential management; choose stand-alone when the opening is isolated.
17) Both the BEST 9KM IDH MAX and the Dormakaba E-Plex 5270 are Grade 1. What actually separates them for a spec?
Both carry a Grade 1 rating, so on durability class they read the same on a submittal. The separation is form and interface. The 9KM IDH MAX is a non-handed cylindrical lever lock built to ANSI/BHMA A156.2 Series 4000, installed in a 2-1/8 inch cross bore with a 9/16 inch throw latch, and is offered in 2-3/4, 3-3/4 and 5 inch backsets across eleven finishes and three lever styles. The E-Plex 5270 is specified as a stand-alone access controller in the 5X70 series. If the drawing calls out a cylindrical lever lock with a specific backset, lever design and finish to match adjacent doors, the 9KM IDH MAX is the one carrying those options.
18) I need the electrified opening to sit on an aluminum storefront with a 5 inch backset. Which of these fits?
The BEST 9KM IDH MAX is offered in a 5 inch backset alongside 2-3/4 and 3-3/4 inch, which is the range that covers narrow stile and wide stile prep as well as standard hollow metal and wood doors. The Dormakaba E-Plex 5270 is a stand-alone access controller in the 5X70 series and does not carry that backset range as a selection. For a storefront opening where backset drives the whole decision, the 9KM IDH MAX is the one to spec, and you pair it with either the 2-3/4 x 1-1/8 inch curved lip strike or the 4-7/8 x 1-1/4 inch S3 strike depending on frame prep.
19) What finishes does the BEST 9KM come in to match the rest of my building's hardware?
Eleven finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM satin chrome antimicrobial and 690 statuary dark bronze. Those are standard BHMA finish codes, so matching an existing opening is a matter of reading the code off the old lock rather than eyeballing the color.
