SDC 110IV Electronic Door Lock 12/24VDC OSDP

SDC 110IV Electronic Door Lock

The SDC 110IV is a dual-voltage electronic lock engineered for commercial and institutional access control deployments. This wired lock operates at either 12VDC or 24VDC—giving you flexibility to match existing power infrastructure without requiring separate regulators or converters. Support for OSDP (Open Supervised Device Protocol) ensures the lock communicates securely and reliably with major access control platforms, eliminating proprietary lock-in and simplifying future system upgrades.

The 110IV integrates NFC/13.56MHz credential technology, meaning cardholders can authenticate using contactless badges or mobile credentials already deployed in your facility. This dual-voltage design with OSDP compatibility makes the 110IV a practical choice for retrofit projects where mixing 12V and 24V power sources is unavoidable, and for new deployments prioritizing standards-based interoperability.

Key Features

• Dual-Voltage Operation (12/24VDC): Eliminates the need for separate power supplies or voltage regulators across different door zones. If your facility mixes 12V legacy readers with 24V newer access panels, the 110IV bridges that gap without extra hardware.
• OSDP Protocol Support: Supervised communication ensures encrypted, tamper-logged credential transactions. OSDP devices report device health and tampering attempts back to the control panel—critical for maintaining audit trails in regulated environments (healthcare, finance, secure facilities).
• NFC/13.56MHz Credential Compatibility: Supports modern contactless card and mobile phone credentials. End users don't need to carry separate key fobs if your identity platform already issues contactless badges.
• Electromagnetic Strike/Latch Functionality: The 110IV functions as either a strike or latch mechanism depending on door frame configuration. Confirm with your door hardware supplier which type your frame requires before ordering; retrofitting the wrong type creates costly installation delays.
• Proximity Reader and Keypad Integration: Flexible credential input—card readers and keypads can be integrated into the same access node, reducing cabling complexity on multi-door panels.
• 628 Satin Aluminum Finish: Low-gloss satin aluminum resists fingerprints and casual tampering attempts better than polished chrome, while maintaining a professional appearance across mixed finishes. Verify finish compatibility with door frame and surrounding hardware before deployment.

Integration & Compatibility

The 110IV's OSDP support ensures compatibility with certified access control platforms including Salto, Genetec, Honeywell ProWatch, and others supporting the OSDP specification. Wired installation requires 18–22 AWG twisted-pair cabling from the main access panel; plan conduit runs and voltage drop calculations before ordering rough-in materials. Confirm with your panel vendor that the 110IV model code (110IV) is pre-loaded in firmware; some legacy systems require manual driver installation.

Frequently Asked Questions

Q: Can the SDC 110IV handle both card readers and keypads simultaneously?

A: Yes. The 110IV supports both proximity reader and keypad credential input on the same device, reducing the number of separate reader modules you need to wire and manage.

Q: Is the 110IV suitable for outdoor door applications?

A: No. The 110IV is designed for indoor commercial and institutional environments. Outdoor applications require weather-sealed housings and gaskets not included in this model. Consult the datasheet for environmental operating limits.

Q: What is the power draw of the 110IV at 12VDC versus 24VDC?

A: The datasheet specifies operating current at both voltages; verify exact draw with the manufacturer PDF before calculating transformer sizing or breaker ratings for your panel.

Q: Does the SDC 110IV support wireless credentials (Bluetooth, WiFi)?

A: No. The 110IV is a wired device supporting NFC/13.56MHz credentials only. Mobile phone credentials work via NFC if your identity platform issues them as NFC-compatible; WiFi and Bluetooth credentials are not supported.

Q: Can I upgrade existing non-OSDP locks to OSDP?

A: The 110IV itself is OSDP-native. If your current locks are non-OSDP, you must physically replace them; OSDP cannot be retrofitted to older models via firmware update.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The SDC 110IV solves a real problem in mixed-voltage access control retrofits. If you're integrating new OSDP-capable panels into a facility that still runs legacy 12V readers on some zones and 24V on others, the 110IV's native dual-voltage design eliminates the need to specify separate lock models or introduce additional power conditioning. That reduces SKU count, simplifies procurement, and cuts installation variance across multi-building campuses.

Technical Highlights:

• Dual-Voltage Input (12/24VDC): Direct support for both standard access control voltages means you don't need to step down 24V to 12V or regulate incoming power—the lock operates correctly at either voltage. Real benefit: fewer transformer modules, lower panel cost, easier troubleshooting when voltage supply margins are tight.
• OSDP Protocol with Supervised Communication: Every credential transaction is logged and encrypted at the device level. In a healthcare facility or secure data center, this beats legacy Wiegand, which broadcasts credentials in plaintext. Tamper events on the lock itself generate immediate alerts to the control panel.
• NFC/13.56MHz Native Support: If your identity management system already issues contactless credentials (typical in enterprise deployments), the 110IV integrates them without requiring separate reader hardware. Reduces cable runs and junction box congestion.

Deployment Considerations:

• This is a wired device only. Plan for 18–22 AWG twisted pair from the main access panel to each door. Wireless-only sites or facilities with incomplete conduit infrastructure should confirm cable routing before specifying the 110IV.
• Indoor environments only. The satin aluminum finish and enclosure design assume climate-controlled spaces. Outdoor vestibules, loading docks, and weather-exposed doors require external housings and gaskets not included.
• OSDP compatibility depends on control panel firmware support. Verify that your specific panel model (Salto, Genetec, Honeywell, etc.) has certified OSDP drivers loaded before commissioning. Legacy access panels may require manual driver upload or firmware patches.

Position the 110IV in commercial office, institutional (education, healthcare), and secure-facility retrofits where you need OSDP's supervised security and dual-voltage flexibility without carrying multiple SKUs. Avoid it for outdoor, wireless, or fully proprietary legacy systems—it will create integration friction instead of solving it.
