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.

Access control door hardware is one of the most profitable and most often overlooked parts of a security installation. Too many dealers install the electronics but leave the hardware portion to someone else — giving up control, compatibility, and margin.

By supplying the hardware yourself and subcontracting only the labor when necessary, you protect your profits, ensure system integrity, and deliver a more complete, dependable solution to your customers.


Why Providing the Access Control Door Hardware Helps Dealers Win

  • You control the spec and integration

  • You retain markup on all hardware components

  • You reduce system conflicts and customer complaints

  • You position yourself as the full-solution expert

  • You can still subcontract labor — but stay in control


Why Controlling the Access Control Door Hardware Helps Dealers Win

  • You control hardware specifications and ensure compatibility

  • You keep the markup on strikes, exit devices, and latch retraction kits

  • You reduce integration issues and avoid finger-pointing between vendors

  • You become the trusted, one-stop solution provider

  • You can still subcontract installation labor when needed


    5 Reasons Dealers Should Control the Hardware Portion of the Job

    1. You Control the Product, Not Just the Labor

    When someone else chooses the hardware, you lose control over a core part of the system. Decisions may be based on convenience or stock availability — not on what integrates best with your platform.

    By supplying the access control door hardware yourself:

    • You ensure full compatibility with the access control system

    • You maintain code compliance and meet ADA and life safety requirements

    • You prevent costly rework or callbacks due to mismatched components


    2. You Capture the Profit Margin

    Every piece of hardware — from an electric strike to a latch retraction kit — is a profit opportunity. When you’re not the one providing it, that profit goes elsewhere.

    Taking control of the hardware supply lets you:

    • Include it in your project quote

    • Apply your markup just as you do with other system components

    • Increase the value of every door in the project


    3. You Reduce Callbacks and System Conflicts

    If a door doesn’t operate properly, the customer calls you — no matter who provided the hardware. If you don’t know exactly what’s on the door, troubleshooting takes longer and costs more.

    When you control the hardware, you also control:

    • The spec and quality of each component

    • How it integrates with readers, panels, and wiring

    • The consistency of operation across all openings


    4. You Can Still Subcontract Labor (Strategically)

    You don’t have to perform every aspect of the mechanical install yourself. Many dealers bring in skilled trades for specific tasks — but keep control of the hardware supply to ensure standardization and compatibility.

    This approach means:

    • You eliminate variability in brand or model selection

    • You maintain consistency across doors, buildings, and projects

    • You avoid unexpected substitutions that can cause integration issues


    5. You Build Long-Term Trust and Standardization

    When you own the hardware portion of the system, you become the single point of accountability. That strengthens your position with the customer and makes future service easier.

    Benefits include:

    • Faster troubleshooting and repairs

    • Easier upgrades and expansions

    • More consistent, predictable system performance


    Dealer Profit Tip: Use Tools That Simplify Hardware Selection

    You don’t need to be a door hardware specialist to spec the right parts. Trusted manufacturers like SDC (Security Door Controls) make it easy for dealers to take ownership of this part of the install:

    1.  LR100 Electric Latch Retraction Kits retrofit easily to existing mechanical exit devices from top brands.

    2.  DoorSnap Mobile App — just take a picture of the door, and SDC tells you what kit you need.

    3.  Dedicated Dealer Support from SESP ensures you always quote the right solution — no guesswork needed.

    With these tools, there’s no reason to give up profit and control to someone else.
