About SDC

SDC (Security Door Controls), founded in 1969 and headquartered in Camarillo, California, is a U.S.-based manufacturer of commercial electric door strikes, magnetic locks, delayed egress hardware, and access control accessories. SDC's product line spans the full commercial door-hardware spectrum with particular strength in specialized applications: delayed egress (DELAY series) for healthcare and retail loss prevention, magnetic locks (MagForce) with outdoor-rated weather sealing, universal strike retrofits (UniLock) for mixed legacy hardware environments, and ExitCheck exit-alarm retrofits for converting non-access-controlled doors.

SDC is owned by Griffin-Cypress and is NDAA Section 889 compliant with manufacturing in California — fitting federal, state, and municipal projects that require U.S.-manufactured door hardware. The company's engineering differentiator is specialized application hardware: SDC's DELAY series is the market-leading delayed-egress solution compliant with NFPA 101 and IBC 1010.1.9, essential for healthcare psychiatric and memory-care wings, high-shrink retail (loss-prevention), and correctional facilities where immediate exit must be electronically delayed for 15-30 seconds.

SDC is backed by a dedicated North American technical support team with extensive experience in the nuanced code-compliance questions that delayed egress, magnetic lock UL ratings, and healthcare-specific door hardware requirements create for integrators.

Where SDC Fits

SDC fits commercial access control projects where specialized applications matter: healthcare (delayed egress for behavioral health, memory care), high-shrink retail (DELAY series for loss prevention), correctional and detention facilities (delayed egress + heavy-duty mag locks), municipal and federal projects requiring NDAA compliance with U.S. manufacturing, and retrofit installations using UniLock universal strikes to avoid door-frame modification. SDC's delayed egress line is the default specification for any project involving NFPA 101 or IBC 1010.1.9 code-compliance requirements.

Why Choose SDC

Delayed Egress Leadership

SDC's DELAY 100 and 1511 series are the market-standard solutions for NFPA 101 / IBC 1010.1.9-compliant delayed egress — essential for healthcare behavioral, memory care, and loss-prevention retail.

U.S. Manufacturing + NDAA

Manufactured in Camarillo, California — NDAA Section 889 compliant and specified for federal, state, and municipal access control projects that exclude foreign hardware.

Specialized Retrofit Hardware

UniLock universal strike retrofit fits most legacy door prep cutouts without frame modification. ExitCheck exit alarms retrofit non-controlled doors with monitored egress.

5-Year Warranty + U.S. Support

SDC ships a 5-year limited warranty on most access control hardware and provides U.S.-based technical support experienced with code-compliance and delayed-egress specification.
