Cut the Core Drilling: SDC WPT Wireless Power Transfer Device Makes Retrofits Easy

Messing with door cores is one of the biggest headaches for security dealers retrofitting electrified hardware—especially when dealing with wood or fire-rated doors. Fortunately, the SDC WPT Wireless Power Transfer Device solves that problem by delivering power and data across the door gap without any moving parts, wires, or core drilling.

Ideal for both retrofit and new construction, this RF-powered solution simplifies installations, minimizes vandal-prone wiring, and keeps projects on schedule. Whether you’re updating an older access control system or installing electric locks on a wood or steel door, the SDC WPT gives you the power—literally—to get the job done cleanly and compliantly.

Key Product Features

  • Wireless RF power transfer—no door core drilling required
  • Compatible with steel and wood doors
  • Transfers both energy and data (REX, DPS, latch status)
  • Visual LED status indicator
  • Field-selectable dual voltage output (12VDC or 24VDC)
  • Up to 1/4” (7mm) door gap tolerance
  • Flexible mounting on latch, hinge, or top frame
  • No moving parts or exposed wires—zero wear points
  • Adjustable unlock trigger (1–90 seconds)
  • Includes fixed 4-second unlock trigger for standard REX

Use Cases & Dealer Benefits

The WPT is a retrofit-friendly, code-compliant solution designed for:

  • Failsecure Electrified Locks and Latches: Power mortise, cylindrical, or rim locks without wiring hassles.
  • High-Traffic Doors: Reduce wear and tear from wire loops and moving parts.
  • Historic and Finished Doors: Maintain door aesthetics without compromising functionality.
  • Healthcare and Schools: Perfect for touchless entry installations using wave-to-open sensors.
  • Compliance Upgrades: Ideal for projects needing to meet UL fire and burglary ratings.

Why Dealers Love It:

  • No Core Drilling = Faster Installs: Save labor and avoid damaging fire-rated or wood doors.
  • Reduced Callbacks: No wires to break or degrade over time.
  • More Tolerant Alignment: Easier to install than inductive wireless devices.
  • Upsell Opportunity: Bundle with electrified locksets, exit devices, and wave-to-open switches.
  • Profitable Retrofits: Unlock more margin on existing door openings where wiring is difficult.

Technical Summary

    • (1) 1–90 second adjustable unlock timer
  • Dry Outputs (Frame Side):
    • (2) SPDT, 1A @ 30 VDC resistive
    • (2) SPST-NO, 100 mA @ 60 VDC resistive
  • Environmental Rating: -4°F to 140°F
  • Weight: 1 lb
  • Certifications:
    • UL 10C Positive Pressure Fire Tests
    • UL 1034 Burglary-Resistant Locking Mechanisms

Note: For use with failsecure (power-to-unlock) locks only. Not compatible with failsafe or continuously dogged locks.

How the SDC WPT Works

Unlike inductive systems that require precise coil alignment, the WPT uses RF energy, which:

  • Transmits power as radio waves across the door gap.
  • Converts the RF signal into usable DC voltage via an internal receiver.
  • Transfers data (REX, DPS, latch status) along with power.
  • Is less sensitive to vertical and horizontal misalignment than coil-based systems.

This makes the WPT more installer-friendly and reliable in real-world deployments—especially in field conditions where perfect alignment isn’t always possible.

Accessory Highlight: WPT Drill Jig

For installers working with solid or particle-filled wood doors, SDC offers a WPT Drill Jig Assembly (part #SDC-WPT), available from JustDoorToolz. This makes prep quick, clean, and precise—ensuring a secure, code-compliant fit for every install.

Security dealers looking to future-proof their access control offerings need look no further than the A22K1BT Kit from CDVI. This powerhouse access control bundle includes the feature-rich A22K controller and two advanced Bluetooth/Mobile credential readers, setting the standard for flexibility, scalability, and user convenience in commercial and institutional access control.

At its core, the A22K1BT doesn’t just offer high-tech hardware—it’s built with military-grade encryption that places it among the most secure systems in the industry. Whether your customers are in education, government, multi-tenant residential, or enterprise, CDVI gives you the tools to offer access control that is as secure as it is smart.

What’s in the Kit?

The CDVI A22K1BT Kit includes:

  • A22K Access Control Panel (2-door, PoE-enabled)

  • Two KRBT Bluetooth Readers (mobile credential compatible)

  • ATRIUM Software (browser-based and free of licensing fees)

The Mobile Credential Advantage

With the KRBT readers, users can unlock doors using CDVI Mobile-PASS credentials. These credentials reside securely on a user’s phone and communicate via Bluetooth for lightning-fast authentication—even offline.

Five methods of mobile access are supported:

  • Facial recognition

  • Fingerprint (touch) scan

  • Voice command

  • Tap-to-enter

  • Automatic (hands-free) detection

No need for a badge, no internet required, and no delay in access. This kind of multi-factor convenience enhances both security and user experience—ideal for hygiene-sensitive or high-throughput environments.

Military-Grade Encryption: AES-128 and AES-256

Where CDVI really differentiates itself is in its use of Advanced Encryption Standard (AES) technology to protect data in transit between mobile devices, readers, and controllers.

AES-128 vs AES-256: What You Need to Know

  • AES-128 uses a 128-bit key length and is already considered highly secure. It’s used in industries such as banking and telecom.

  • AES-256, with its 256-bit key, offers exponentially greater resistance to brute-force attacks—so much so that it’s the encryption standard approved for top-secret U.S. government and military data.

Most access control systems, even modern ones, stop at AES-128. CDVI goes further.

CDVI utilizes both AES-128 and AES-256 encryption protocols, setting a benchmark for high-security environments where safeguarding user credentials and access data is paramount.

This level of encryption helps protect against:

  • Credential cloning

  • Man-in-the-middle attacks

  • Data sniffing or interception

  • Unauthorized duplication or access spoofing

For security dealers working with enterprise or government clients, CDVI’s encryption stack becomes a serious competitive advantage.
