SDC/Security Door Controls 1571Y Electromagnetic Lock
Overview
The SDC 1571Y is a 24VDC electromagnetic lock strike designed for access control integration in commercial and institutional door security applications. This unit functions as a fail-secure electromagnetic locking mechanism, holding doors in the locked position under power and releasing when de-energized. Suitable for integrators deploying controlled-access entry systems where electronic lock coordination is required.
Compatibility
Compatible with standard door frame installations requiring electromagnetic strike retrofit or new construction. Integrates with access control systems that provide 24VDC power switching and logic-level door release signaling. Suitable for use in multi-door access control deployments where centralized credential readers and controllers manage individual lock states.
