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

  • Power Input (Frame Side): 600 mA @ 24 VDC
  • Power Output (Door Side):
    • 600 mA @ 12 VDC
    • 300 mA @ 24 VDC

  • Dry Inputs:
    • (1) 4-second fixed unlock trigger
    • (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.

The Covid-19 Pandemic is unlike anything that we have ever seen in our lifetimes.  The global economy was basically shut down over night, leaving an economic contraction in its wake.  The Security Industry has an inverse relationship with economic contraction – when the economy declines, crime goes up and ultimately drives security sales.  But don’t count on that alone.  Sure, there will be new sales driven by crime, but this contraction will cut deep and most likely, drive the United States into recession.  Assessing business levels in the future is always a difficult task, even in expansionary times, as none of us have a crystal ball. Security professionals need to consider a variety of factors that can contribute to sales or lack of sales.

  • Increases in crime – Will tough economic times lead to more crime?  If so, will increases in crime drive new sales?  What type of products will be in demand?
  • Government stimulus – Stimulus dollars may come from state, local and/or federal programs and the security professional should investigate how to be a part of it.
  • New Products – What new products have been introduced to solve virus related problems?  Do they really work, and will it solve my customer’s needs?
  • Existing products – New problems can be solved with existing products; what products are available to solve them (like face recognition readers and automatic door openers)
  • Social distancing – How will social distancing affect how I do business?  Will customers take in person meetings?  If not, how can I differentiate myself remotely?  How can I ensure to my customers that I am taking it seriously?
  • Regulations – What new regulations may affect future sales?
  • Supply shortages and overages – Will supply channels be enough to satisfy demand?  Are manufacturers seeing a shortage in components limiting production and increasing lead times (yes).
  • Pricing – Will short supply increase prices?  Will over-supply decrease prices?
  • Labor – Do I have the necessary labor to install what I sell in a timely manner?
  • Government bans – Is there any products banned by the government like Chinese manufactured cameras?  Will the FDA ban thermal cameras?
  • Credit – Are my distribution channels decreasing my credit or terms?
  • Competition – Will I be able to outwork my competition?  What can I do to be competitive?

All these factors should be considered when planning for future business levels, but one thing is for certain, this too will pass but only time will tell how the security industry will fare during these unprecedented times.
