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 and fire alarm contractors are always on the lookout for products that add value, are code-compliant, and offer recurring service opportunities. The CM-E1 carbon monoxide detector from Macurco fits that profile perfectly. Designed specifically for residential and light commercial use, the CM-E1 offers reliable CO detection while integrating seamlessly into any fire or security panel. And unlike traditional CO detectors, the CM-E1 delivers long-term performance with minimal maintenance—making it a solid win for both installers and building owners.

Key Product Features

  • Flush or surface mount options for flexible installation

  • Low-voltage operation (9–32 VDC) for fire/burg system compatibility

  • Built-in sounder with Temporal 4 pattern

  • UL 2075 Listed and California State Fire Marshal approved

  • Long-life sensor with no calibration required

  • Simple clip-in wire harness for fast replacements

  • LED status indicators (red alarm, amber trouble, green normal)

  • SPST alarm and trouble relays (100mA @ 40VDC)

  • Field testable with optional test gas

  • Made in the USA

Where It Fits—and Why Dealers Love It

The Macurco CM-E1 was engineered for areas where standard household CO alarms fall short. Whether you’re installing a new security system in a single-family home or upgrading a mixed-use building with a new fire panel, this detector offers an opportunity to upsell while enhancing safety.

Ideal Applications:

  • Private residences and apartments

  • Hotels, dormitories, and condos

  • Retail shops and office buildings

  • Lobbies, common areas, and mechanical rooms

  • Light commercial buildings and airport terminals

For dealers, the CM-E1 isn’t just a better detector—it’s a profitable one. With no calibration needed, a 10-year sensor life, and easy mounting options, this unit reduces installation time and minimizes service callbacks. Plus, the form factor and flush mount options mean you can offer a clean, professional finish your clients will appreciate.

The Hidden Revenue Stream: CO Detector Replacements

Many dealers overlook the recurring revenue potential in scheduled detector replacements. The CM-E1 offers a 10-year end-of-life (EOL) notification, ensuring your customers stay protected while opening the door to scheduled replacement programs.

Need to replace dozens—or even hundreds—of aging plug-in units with system-connected CO detectors? The CM-E1 makes that transition seamless. It’s a perfect opportunity to lock in future business and increase RMR by offering preventative maintenance contracts, especially in high-occupancy buildings like condos or assisted living facilities.
