SDC LR100VDK-22-EM Von Duprin 22 ELR Controller Kit
The LR100VDK-22-EM is a wired access control controller from Security Door Controls, purpose-built for Von Duprin 22 ELR (Electronic Locking Mechanism) strike installations. This kit centralizes credential management and network control across multiple secured entry points, making it a practical choice for mid-to-large enterprise deployments where multi-door coordination is required.
Key Features
- 4-Door Capacity: The controller manages up to 4 independent doors simultaneously, which means you can coordinate access policy across an entire facility zone (security checkpoint, warehouse perimeter, office suite) without needing separate control nodes for each opening. Reduces complexity and wiring runs compared to door-by-door controllers.
- 250,000 User Credentials: Accommodates large user populations — useful if you're managing a multi-building campus or high-turnover facility. You won't need to partition credential databases across multiple controllers in typical enterprise environments.
- TCP/IP & OSDP Support: Dual protocol support means the LR100VDK-22-EM works in both legacy IP-based access control networks and modern OSDP installations. If you're migrating infrastructure incrementally, this flexibility avoids a rip-and-replace scenario. OSDP also provides secure communication and command integrity — important for audited facilities.
- Von Duprin 22 ELR Integration: Factory-matched pairing with Von Duprin 22 series electronic locks eliminates compatibility guesswork. Strike assembly, power timing, and fail-safe/fail-secure modes are pre-configured for this specific lock family.
- HID Credential Reader Ecosystem: The kit integrates with HID-based readers (card, proximity, mobile credential platforms). If your site already runs HID infrastructure elsewhere, this reduces vendor fragmentation and simplifies badge administration.
- Wired Connectivity: Hardwired network and power connections eliminate wireless dropout risk. Ideal for high-security areas where radio interference or intentional jamming could compromise access control. Trade-off: less flexible installation footprint than wireless, but deterministic performance in mission-critical doors.
Integration & Compatibility
The LR100VDK-22-EM (often searched as LR100VDK 22 EM) is designed for security integrators deploying centralized access control systems in enterprise environments. The controller pairs with Von Duprin 22 strike systems and HID credential readers, supporting both TCP/IP and OSDP protocols. This enables you to integrate the kit into existing IP networking infrastructure without dedicated access control backbone upgrades in smaller deployments.
Network architecture flexibility is a key advantage. TCP/IP mode allows integration with standard network video recorders, ethernet switches, and PoE infrastructure you may already operate. OSDP mode supports modern security platforms emphasizing encrypted, auditable credential flow — useful if compliance frameworks (healthcare, banking, government) require command-level integrity logging.
Deployment Scenarios
This kit addresses several practical use cases:
- Warehouse Entry Control: Manage receiving dock, secure storage, and shipping bay access through a single controller. Multi-door coordination prevents tailgating and maintains inventory accountability.
- Office Suite or Floor Access: Secure a multi-office tenant space where badge readers at entry/exit need coordinated unlock timing and credential validation across all doors.
- School or University Building: Manage classroom wing access, secure labs, and administrative areas with centralized credential policy — useful for after-hours lockdown scenarios.
- Healthcare Facility Zones: Pharmacy, pharmacy prep, and medication storage areas often require multi-door access coordination to meet HIPAA audit trail requirements. OSDP support aids compliance logging.
Frequently Asked Questions
Q: Does the LR100VDK-22-EM work with non-Von Duprin 22 ELR strikes?
A: No. The LR100VDK-22-EM is engineered specifically for Von Duprin 22 series electronic locks. Using it with incompatible strike hardware may result in power sequencing failures or improper fail-safe operation. If you need a controller for a different lock family, consult an integrator or the manufacturer for the correct model.
Q: Can I use the controller with wireless readers?
A: The controller itself is wired (no wireless transceiver). However, HID offers wireless reader platforms that communicate to a wired bridge device; that bridge would then connect to the LR100VDK-22-EM via TCP/IP. Wireless readers are not directly supported by the controller.
Q: What's the difference between TCP/IP and OSDP mode?
A: TCP/IP mode integrates the controller into standard IP networks, suitable for smaller deployments or sites already using IP-based access control. OSDP (Open Supervised Device Protocol) offers encrypted credential exchange and audit trail support, required by some compliance frameworks. Your integrator can typically configure either mode at commissioning.
Q: How many reader devices can connect to the LR100VDK-22-EM?
A: The controller supports up to 4 doors, meaning up to 4 reader positions (typically one at entry, one at exit per door, or split across multiple zones). Exact reader count depends on whether readers are daisy-chained or individually wired — your integrator will size the reader loop during design.
Q: Is there a battery backup option for power loss?
A: The LR100VDK-22-EM datasheet does not detail on-board battery backup. For fail-safe/fail-secure behavior during power outage, consult the Von Duprin 22 strike specifications and your integrator. Backup power is typically provided by a separate UPS or battery backup module, not by the controller itself.
Q: Can I upgrade the credential database if I exceed 250,000 users?
A: The 250,000-user limit is a hardware constraint of the LR100VDK-22-EM. If your deployment grows beyond that, you would need to add a second controller unit or migrate to a higher-capacity system. Plan for credential database scaling during initial design if user growth is anticipated.

The LR100VDK-22-EM is a solid, no-frills wired controller for multi-door Von Duprin 22 installations where you need centralized credential management and deterministic network control. The 4-door capacity with 250,000-credential support makes this a practical fit for mid-market deployments — office buildings, smaller campuses, warehouse zones — without over-engineering into enterprise-scale panel costs.
Technical Highlights:
- 4-Door Simultaneous Control: Coordinates entry/exit timing across multiple strike assemblies from a single unit, reducing wiring and panel real estate compared to four standalone controllers.
- 250,000 Credential Database: Scales to larger user populations without requiring database partitioning across multiple controllers in typical enterprise environments.
- TCP/IP + OSDP Dual Protocol: Allows deployment in either legacy IP-based access control networks or modern encrypted OSDP infrastructure — useful if you're mid-migration and can't afford a simultaneous rip-and-replace.
Deployment Considerations:
- Wired connectivity means no wireless dropout risk, but installation footprint is less flexible than wireless options. This is intentional for high-security doors where radio jamming or interference could compromise access.
- The controller is locked to Von Duprin 22 ELR strikes — don't try mixing hardware families. Strike compatibility is pre-engineered; deviating from it creates power sequencing and fail-safe behavior unpredictability.
This kit works best for integrators handling a 4-door mid-market project (warehouse, office suite, healthcare wing) where you need centralized policy without the complexity of a full-scale enterprise access control platform. If you're managing 10+ doors or need credential federation across multiple sites, consider stepping up to a larger SDC panel or enterprise access control system.
