BEST 9KM37DDEU14MSS3626 – 9KM IDH MAX Grade 1 Electrified Cylindrical Lock with Magnetic-Stripe Reader combines a heavy-duty commercial cylindrical lever lock, integrated electronic card reader, electrified locking control and door monitoring in one streamlined opening. This model is configured with 2-3/4-inch backset, 7-pin BEST interchangeable-core housing, DDEU electrically unlocked (fail-secure) function, #14 curved-return lever, MS magnetic-stripe card reader, ANSI S3 strike and 626 / US26D Satin Chrome finish.

The 9KM IDH MAX is a hardwired access-control lockset for compatible commercial access systems. Instead of mounting multiple separate devices at the opening, IDH MAX integrates a card reader and hardware monitoring into the lockset assembly to simplify installation and appearance. The DDEU fail-secure configuration keeps the outside lever locked when power is removed and allows outside lever access when the appropriate 12V DC power is applied; the inside lever remains available for egress, subject to the complete approved installation.

Key Features & Benefits

• BEST 9KM IDH MAX: integrated door hardware platform for commercial wired access-control systems.
• ANSI/BHMA A156.2 Grade 1: heavy-duty cylindrical lock chassis for demanding commercial and institutional service.
• Magnetic-Stripe Reader (MS): credential reader mounted in the lock escutcheon; specify compatible cards, card-track configuration and access-control interfaces.
• Electrically Unlocked (DDEU): fail-secure operation—outside lever locks without power and unlocks on authorized electrical activation.
• 7-Pin Interchangeable-Core Housing: intended for compatible BEST interchangeable cores and mechanically keyed override; confirm the correct core and keying arrangement.
• #14 Curved-Return Lever: durable return-style commercial lever with a curved hand-grip design.
• ANSI S3 Strike: manufacturer-designated 4-7/8-inch ANSI strike configuration.
• Integrated Door Monitoring: IDH MAX cylindrical locks include request-to-exit and door-contact/door-position sensing functions.
• Simplified Door Wiring: BEST describes a four-conductor wire run to the compatible lock/interface assembly, reducing separately mounted door devices.
• 12V DC Operation: 10.2–13.2V DC input per manufacturer specifications; not a battery-operated standalone lock.
• Mechanical Key Override: supports authorized keyed access when equipped with a properly keyed compatible core.
• 626 / US26D Satin Chrome: satin-chromium architectural finish for standard commercial hardware schemes.

Technical Specifications

Typical Commercial Applications

For appropriately specified office buildings, colleges, schools, healthcare facilities, government facilities and commercial properties requiring integrated magnetic-stripe credential access at a heavy-duty cylindrical lever opening. Suitable for facility upgrades where a compact wired lock-and-reader assembly is preferred over separately installed card readers, strikes and monitoring devices.

Installation & Compatibility

Confirm the exact magnetic-stripe card format and track, access-control panel/PIM compatibility, electrical power and wiring, door and frame preparation, strike, fasteners, hinge or power-transfer device, and BEST interchangeable-core/keying requirements before purchase. The 9KM uses a modified door preparation to accommodate the IDH MAX escutcheon. A compatible external control system, power source, transfer wiring and credentials may be needed and are not represented here as part of the base lock. Verify whether a keyed core is included with the chosen purchasing configuration; the 7-pin designation identifies the housing.

Life-safety note: Fail-secure outside locking must be evaluated against applicable egress, accessibility, fire-door and building-code requirements for the specific opening. The inside lever is designed to provide egress under normal listed operation; confirm the complete approved installation, including power-loss behavior, with the access-control designer and authority having jurisdiction.

The current catalog describes this variant as: BEST 9KM37DDEU14MSS3626 IDH MAX Grade 1 electrified cylindrical lock with magnetic-stripe reader, fail-secure DDEU function, S3 strike Use its complete ordering code when matching an existing access-control hardware specification. This listing belongs to the Electrified Cylindrical Lock category, where lever, switch function, door handing, credential type and hardware compatibility can differ significantly among nearby model numbers.

SKUs and Variant Choices

The BEST IDH MAX electrified cylindrical lock is the specific magstripe-reader, fail-secure configuration identified by its factory model code. It should be selected for facilities using compatible magnetic-stripe access credentials and the required control infrastructure, rather than substituted for a PIN keypad, contactless smart-card reader or mobile-credential lock.

Technical Buying Checklist

1. Confirm the IDH MAX 9KM model, 14 lever, 626 Satin Chrome finish and the specified S3 strike configuration.
2. Check cylinder bore and backset, door thickness, handing, latch and frame strike preparation against the model template.
3. Confirm magstripe credential format, supported programming requirements and facility access-system integration.
4. Verify the intended fail-secure behavior, backup access, proper power/credential management and unrestricted inside egress.
5. Confirm hardware inclusion and any separate keying, control hardware or mounting parts before ordering.

For properly engineered employee-entry, office and institutional doors requiring commercial electronic cylindrical access control.

Ordering Notes for Commercial Door Worx Customers

Verify the required mechanical function, available door cutouts, core/keyway and any electrical wiring or enrollment instructions against the manufacturer's current documents before installation. Confirm exactly which operating cores, control keys, accessories and service software are supplied with the chosen variant. The factory part number is more specific than the broad lock series name; order the exact listed SKU.
