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.

Delayed egress systems provide a code-compliant way to manage building security while still allowing safe emergency exits—making them a must-know solution for security dealers working in healthcare, retail, education, and behavioral health environments. These systems delay exit through secured doors for a preset period (usually 15 or 30 seconds), giving time for response or deterrence while complying with life safety codes.

For dealers, delayed egress isn’t just about code compliance—it’s a powerful upsell opportunity that adds real value to your projects. And with tools like SDC’s DoorSnap™ app, it’s easier than ever to specify the right hardware, avoid callbacks, and even sub out labor on challenging installs without losing margin or control.

Key Features of Delayed Egress Systems

  • 15- or 30-second exit delay to deter theft or unauthorized exit

  • Local alarm and voice prompts to alert staff and occupants

  • Automatic release upon fire alarm or loss of power

  • Code-compliant operation (NFPA 101, IBC, IFC)

  • Integration-ready with access control, fire alarm, and video surveillance

  • Works with a wide range of electrified locks and exit devices

  • ADA-compliant designs available

Why Dealers Should Be Selling Delayed Egress

Delayed egress systems are often overlooked until a client requests them—but savvy dealers know to lead with the solution, especially in verticals where wandering, theft, or unauthorized exits are real concerns.

Here’s why dealers should offer delayed egress as a standard option:

  • Higher ticket value: Bundling delayed egress hardware boosts total system value

  • Code-driven demand: Required in many applications, from memory care to big-box retail

  • Customer peace of mind: Deters casual theft and protects vulnerable populations

  • System stickiness: Integrates deeply with access control, making your installation harder to replace

  • RMR potential: Tie into alarm monitoring or access system support plans

SDC’s range of delayed egress solutions—including their EntryCheck®, ExitCheck®, and SureExit® product lines—allows you to customize solutions for any environment. Whether you’re dealing with glass doors, fire-rated openings, or high-traffic retail exits, SDC has you covered.

Dealer Profit Tip: Use DoorSnap to Control the Hardware Sale

One of the biggest missed opportunities in access control is letting the locksmith or door vendor handle the hardware. Dealers who rely on others often end up:

  • Paying a markup on hardware

  • Dealing with hardware that doesn’t integrate

  • Losing profit and project control

That’s where the DoorSnap™ app from SDC comes in. With just a few photos and a few details, dealers can quickly identify the exact electric locking hardware needed for the opening. Whether it’s a delayed egress application or not, DoorSnap:

  • Eliminates guesswork

  • Prevents ordering errors

  • Ensures compatibility with delayed egress devices

  • Allows you to own the hardware and sub out labor only when needed

This means you retain profit, reduce callbacks, and keep your customer relationship strong.

Common Applications for Delayed Egress

1.  Hospitals and memory care units
Prevent wandering patients or residents from exiting unnoticed while still allowing safe egress during fire alarms.

2.  Retail stores and stockrooms
Deter shoplifting and push-outs through back exits by slowing down unauthorized departures.

3.  School campuses and daycare centers
Protect children by securing perimeter doors against unauthorized exit.

4.  Behavioral health and correctional facilities
Maintain control over exits without compromising life safety.

5.  Airports and secure zones
Keep passengers from crossing into unauthorized areas while maintaining code compliance.
