SDC 482S-KIT 4-Door Access Control Controller
The SDC 482S-KIT is a wired access control controller designed to manage up to four independent doors with support for 250,000 user credentials—a capacity that handles mid-to-large enterprise deployments and multi-site security integrations without requiring credential server sprawl. Operating at 28VDC, this ADA-compliant 4.5-inch square controller integrates directly into HID-based access control ecosystems, eliminating the need for third-party gateways or protocol converters.
Key Features
- Four-Door Management: Handles four independent door lines simultaneously, meaning a single 482S-KIT can replace multiple smaller controllers in retrofit or new-build scenarios where space and consolidation matter.
- 250,000 User Credential Capacity: Enough headroom for enterprise-scale deployments without credential database bloat or performance degradation as your facility grows.
- OSDP Native Support: Open Supervised Device Protocol certification enables vendor-neutral architecture—you're not locked into a single access platform ecosystem. Swap readers or upgrade your access management software without replacing the controller.
- TCP/IP Connectivity: Direct network integration supports cloud-based management platforms and enterprise access control software, avoiding isolated control islands. Enables centralized monitoring and audit logging across multiple locations from a single pane of glass.
- HID Reader Compatibility: Works directly with HID credential readers (Prox, iClass, Mobile) without middleware. Streamlines installation and reduces certification testing overhead in retrofit projects.
- 28VDC Power Requirement: Standard industrial voltage makes wiring straightforward in existing electrical infrastructure; 28VDC supplies are commodity items with multiple sourcing options, reducing single-vendor risk.
- ADA-Compliant 4.5-Inch Square Form Factor: Fits standard electrical enclosure cutouts and wall boxes, simplifying installation in existing facilities without custom modifications or oversized hardware.
Integration and Compatibility
The 482S-KIT (often searched as 482S KIT) integrates seamlessly with access control systems built on OSDP and TCP/IP standards. Native HID reader support means no additional reader converters, and OSDP certification ensures that hardware lock-in won't constrain your future platform choices. Suitable for new installations and retrofit deployments where four-door control and high user capacity are required. Deploy this controller alongside modern credential readers and centralized access management to avoid the cost and complexity of distributed, single-door solutions.
Deployment Considerations
The 482S-KIT requires a stable 28VDC power source and network connectivity (wired Ethernet). Plan your cable runs during the design phase—network latency shouldn't exceed manufacturer recommendations for real-time credential updates. In multi-site deployments, centralize your access management server to avoid per-site credential synchronization headaches. If your facility runs legacy Wiegand-only readers without OSDP support, confirm gateway compatibility before specifying; OSDP compliance doesn't backport to older protocols. For high-availability deployments, consider redundant network paths and backup credential storage to maintain door access if the primary TCP/IP link drops.
Frequently Asked Questions
Q: Does the SDC 482S-KIT work with non-HID readers?
A: The 482S-KIT is designed for HID credential readers. OSDP support enables compatibility with readers from other vendors that implement the Open Supervised Device Protocol standard. Legacy Wiegand readers may require a gateway or converter—verify with your integrator before installation.
Q: What happens if the network connection drops?
A: The controller's local credential cache allows door access to continue using stored credentials until network connectivity is restored. Review the datasheet for offline hold-time specifications and configure your access software accordingly.
Q: Can I install the 482S-KIT outdoors?
A: The controller is designed for indoor electrical enclosures. For outdoor applications, mount the 482S-KIT in a weatherproof cabinet or enclosure and bring conduit runs to outdoor readers. Verify NEMA rating of your enclosure to match local environmental conditions.
Q: How many 482S-KIT controllers can I network together?
A: There is no hard limit on the number of controllers on a single network, but your access management platform may impose licensing or architecture constraints. Consult your platform documentation and integrator for guidance on scaling across multiple locations.
Q: What is the warranty on the SDC 482S-KIT?
A: Warranty details are provided by the manufacturer and your specialty distributor. Request the full warranty terms and any available extended service plans during procurement.

The SDC 482S-KIT addresses a real integration pain point: consolidating four independent door lines under a single controller without sacrificing flexibility or future platform options. At 250,000 credentials, this unit scales past the typical small-business bracket and into enterprise territory—critical if you're managing a multi-tenant facility, warehouse, or corporate campus where a single shared platform beats managing separate access databases per location.
Technical Highlights:
- OSDP Certification: Native Open Supervised Device Protocol support means reader and platform independence. You avoid proprietary lock-in and can integrate third-party OSDP readers without converters—real financial advantage in a heterogeneous security stack.
- Four Independent Door Lines: Each door gets its own control circuit, so one malfunctioning reader doesn't cascade into other doors. Deploy redundancy at the application level without hardware duplication.
- 250,000 Credential Capacity: Enterprise-scale user management without server dependencies. Offline operation using the local credential cache keeps doors operational if your access management platform is unreachable.
- TCP/IP + HID Native Integration: Direct network connectivity and HID reader compatibility eliminate middleware—faster commissioning, fewer potential failure points, simpler troubleshooting.
Deployment Considerations:
- The 482S-KIT must be installed in an indoor enclosure; outdoor applications require a weatherproof cabinet and conduit runs to readers. Don't assume you can mount it directly on an exterior wall.
- Network architecture matters: TCP/IP connectivity means your access management platform is a single point of failure if you don't design for redundancy. Plan your network topology and credential cache strategy upfront—offline hold time is finite.
- HID reader requirement is not a limitation in modern deployments, but it does exclude legacy Wiegand-only infrastructure without a converter. If you're retrofitting an older facility with hardwired Wiegand readers, confirm gateway availability before committing the 482S-KIT to the project.
Position the 482S-KIT for multi-door enterprise consolidation in facilities where OSDP reader compatibility and centralized platform management outweigh the cost of single-door controllers. It's the right choice for warehouse facilities, campuses, and multi-tenant buildings where one unified controller beats four isolated boxes—but only if your network infrastructure and access management platform support it.
