Sdc 1561SV Surface Mount Shearlock 12-24V

Product Description

The SDC Security Door Controls 1561SV is a surface-mount shearlock electromagnetic locking device designed for access control applications on commercial and institutional doors. Unlike traditional electromagnetic locks that hold in tension, a shearlock engages in shear force, making it well suited for doors where a low-profile, flush-mount appearance is required. The 1561SV operates on a dual-voltage input of 12 to 24 volts DC, offering flexibility across a range of access control panel configurations. It ships in a 628 finish, which corresponds to a satin aluminum appearance. Installation and integration are handled by licensed access control or low-voltage security technicians.

The 1561SV is intended for surface-mount installation on commercial doors including single and paired aluminum storefront doors, hollow metal frames, and interior access-controlled openings in office, healthcare, and institutional settings. Its dual-voltage operation makes it compatible with a broad range of access control power supplies and controllers. The 628 satin aluminum finish is commonly specified for aluminum storefront and curtain wall door hardware to achieve a consistent architectural appearance.

Installation Notes

Installation should be performed by a licensed low-voltage or access control technician in accordance with applicable local codes and NFPA 70 (NEC) requirements. Power down the access control panel and disconnect all power to the locking circuit before beginning installation or wiring work. Verify door frame alignment carefully before mounting, as shearlock performance depends on precise alignment between the lock body and the strike plate. Consult the manufacturer product manual for mounting hardware requirements and wiring diagrams before proceeding.
