SDC 1562ITC Electronic Lock and Strike Armature

SDC 1562ITC Electronic Lock and Strike Armature

The SDC 1562ITC is an integrated electronic lock and strike assembly designed for credential-based access control installations where centralized door management and audit logging are required. This unit combines locking mechanism and armature strike in a single form factor, reducing installation complexity and potential failure points in multi-door deployments.

Key Features

• Integrated Lock and Strike Design: Single assembly eliminates the need for separate lock and strike components, cutting installation time and reducing wiring complexity — a significant advantage in retrofits or expansions where cable runs are constrained.
• 24VDC Operation: Runs on standard 24VDC power distribution, widely available in commercial control systems. Integrates with existing door controller power supplies without requiring additional PSU hardware.
• OSDP Protocol Support: Compatible with OSDP-compliant access control panels, meaning credential verification and unlock commands flow through a standardized, auditable protocol. Real benefit: you can swap readers or controllers without redesigning your door architecture.
• NFC/13.56MHz Reader Compatibility: Works with proximity card readers and keypad readers operating at 13.56MHz (ISO/IEC 14443 Type A/B frequency). Supports both contactless card and proximity badge credential types without requiring separate decoder boards.
• Wired Architecture: Hard-wired connection to the control panel ensures reliable, real-time lock state feedback and eliminates wireless latency or range concerns. Audit trail includes every unlock event, access time, and credential used — mandatory for institutional compliance (education, healthcare, government).
• Commercial and Institutional Grade: Engineered for high-cycle environments where door traffic and credential volume are consistent. Suitable for deployment across multi-door access control systems where centralized credential verification and event logging are required.

Integration and Compatibility

The 1562ITC pairs with any OSDP-enabled access control panel or door controller. If your existing system uses an older Wiegand or RS-485 protocol, you will need a protocol converter or panel upgrade — OSDP is not backwards compatible with legacy serial protocols. Proximity and keypad readers must support 13.56MHz NFC operation; older 125kHz EM-based readers will not function without a separate frequency converter. Power supply must deliver stable 24VDC at adequate current for the number of doors on the circuit — consult your control panel documentation for load calculations.

Deployment Considerations

The 1562ITC is a wired device — install it during new construction or plan for visible conduit runs in retrofit scenarios. It is not suitable for wireless, battery-powered, or standalone gate/barrier applications. If you require battery backup for emergency egress, integrate the lock with a UPS-backed 24VDC supply, not a local battery on the lock itself. The unit does not include a separate power supply; use the panel's integral 24VDC output or a dedicated access control PSU rated for your circuit load.

When to Choose a Different Model

If you need wireless door locks or battery-powered autonomous locks, look for alternative architectures outside the SDC wired product line. If your control system does not support OSDP and you cannot upgrade, you will need a different lock family that supports Wiegand or older RS-485 serial protocols.

Frequently Asked Questions

Q: Is the SDC 1562ITC compatible with my existing Wiegand-based access control system?

A: No. The 1562ITC requires an OSDP-compliant panel. If your system uses Wiegand protocol, you will need either to upgrade the panel or select a different lock model that supports Wiegand.

Q: What 24VDC current draw should I plan for per door?

A: Consult the SDC 1562ITC datasheet for the exact energize and hold current specifications. Plan your PSU capacity accordingly — undersizing can cause intermittent lock failures.

Q: Can I use the 1562ITC with 125kHz proximity readers?

A: No. The 1562ITC is rated for 13.56MHz NFC readers. 125kHz readers will not communicate with this lock; you must use compatible NFC/ISO14443 readers.

Q: Does the 1562ITC provide emergency egress?

A: Egress behavior is controlled by your access control panel programming and compliance requirements (typically fail-safe / unlock-on-power-loss). Wire the lock in accordance with your fire and safety codes.

Q: Is the SDC 1562ITC NDAA compliant?

A: Compliance certification is not documented in available evidence. Contact SDC directly or your distributor for NDAA Section 889 or TAA status if required by your organization.

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

The SDC 1562ITC is a straightforward lock-and-strike pairing designed for OSDP-based multi-door access control systems. It's not glamorous, but in institutional deployments (K–12, higher education, healthcare, government facilities) where audit trails and centralized credential management are non-negotiable, this integrated approach eliminates point-of-failure complexity and wiring clutter.

Technical Highlights:

• Integrated Assembly: Combining lock and strike eliminates separate striker installation, conduit runs, and feedback wiring — measurable time savings on projects with 10+ doors and constrained budgets.
• OSDP Protocol: Standardized command and audit interface means credential decisions happen at the panel level, not at the door. If you need to change reader hardware later, the lock itself requires no reconfiguration.
• 13.56MHz NFC Compatibility: Modern proximity/contactless card standard reduces credential cloning risk compared to older 125kHz EM technology. Plan reader procurement carefully — not all proximity readers support 13.56MHz.

Deployment Considerations:

• Hard-wired only — this is a penalty if you're retrofitting existing facilities with limited conduit. Wireless alternatives will cost more but eliminate cable runs.
• OSDP requirement is a hard gate. If your panel is older (Wiegand-era legacy systems), a protocol bridge or panel replacement is mandatory — no workaround exists.
• 24VDC load planning is critical. Under-specified PSUs cause intermittent lock failures at night when building climate control and other loads peak. Size your power supply for peak concurrent unlock demand, not average.

The 1562ITC is the right call for new institutional access control projects where credential auditing is enforced by policy and you control the panel architecture. Skip it if you're retrofitting into existing Wiegand infrastructure or if wireless is a hard requirement.
