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.

For many security dealers and integrators, magnetic locks have long been a standard solution for access control. But while they do the job, mag locks can be bulky, visually intrusive, and more challenging to integrate into certain applications—especially where building codes and aesthetics are equally important.

The Z7200 Series Electric Cylindrical Lock from SDC offers a smarter, cleaner alternative. Designed for commercial-grade durability and code compliance, this electrified lockset installs like a standard cylindrical lock but delivers the advanced security and fire door integrity that modern projects demand.


Key Product Features

  • Heavy-duty cylindrical lock design with solenoid control

  • Maintains fire door rating—remains latched even when unlocked

  • ANSI Grade 1 construction for commercial durability

  • Compatible with both new installations and retrofits

  • Vandal-resistant clutch mechanism

  • Field-selectable dual voltage (12/24 VDC) with included power regulator

  • Optional Request-to-Exit (REX) or Latch Status (LS) monitoring

  • Available in failsafe or failsecure configurations

Use Cases & Dealer Advantages

The Z7200 Series is designed for commercial, institutional, and industrial applications where both appearance and function matter.

Why Dealers Choose the Z7200 Over Mag Locks:

  • Cleaner Look: No visible armatures or brackets—installs like a standard cylindrical lock.

  • Code Compliance: Stays latched even when unlocked, helping maintain fire door integrity.

  • Retrofit-Friendly: Replaces most brands of mechanical locksets with minimal modification.

  • Lower Maintenance: Fewer moving parts than many alternatives reduce service calls.

Fire and Life Safety Ready:
SDC electrified locksets are building and fire life safety code compliant for fire-rated office doors, corridor doors, lobby doors, exit doors, and stairwell doors. This compliance makes the Z7200 Series Electric Cylindrical Lock a natural fit for projects where security and code adherence must go hand-in-hand.

Common applications include:

  • Schools and universities

  • Healthcare facilities

  • Office buildings

  • Government and municipal buildings


Powering the Z7200

Like all electrified locks, the Z7200 Series Electric Cylindrical Lock requires a power transfer method from the frame to the door. Dealers have two practical choices:

  • Wired Power Transfer Devices: The most common and straightforward option for security dealers. These include electrified hinges, concealed loops, or surface-mounted power transfer units. They’re quick to install, cost-effective, and require no specialized locksmith tools.

  • Wireless Power Transfer (WPT): Uses inductive technology to transmit power across the door gap without exposed wiring. It offers the cleanest look but does require a cut-in to the door.


Technical Summary

  • VModels:

    • Z7250 – Locked Outside Only, Failsafe

    • Z7252 – Locked Outside Only, Failsecure

  • Input Voltage: 12 or 24 VDC (±10%)

  • Current Draw: 600 mA @ 12 VDC / 300 mA @ 24 VDC

  • Door Prep: ANSI A115.2, 2-3/4” backset

  • Certifications: UL 10C, ULC-S104, CSFM Listed

  • Monitoring: SPDT, 3A @ 30 VDC resistive


Why This Lock Helps Dealers Sell More

The Z7200 Series Electric Cylindrical Lock gives dealers a product that’s easier to integrate, faster to install, and more appealing to architects and end-users. It reduces callbacks, opens up retrofit opportunities, and provides a premium option when magnetic locks aren’t the best fit.

With multiple finish options, field-selectable voltage, and both failsafe and failsecure models, the Z7200 offers the flexibility to meet almost any project requirement—while still delivering a clean, integrated look.
