Hes 310-4S 24D 630 Electric Strike Fail Secure 24VDC

Product Description

The HES 310-4S 24D 630 is a fail-secure electric strike designed for use in commercial and institutional access control applications. In the fail-secure configuration, the strike remains locked when power is removed, making it the correct choice for doors that must stay secured during a power outage. The unit operates on 24 volts DC and is finished in satin stainless steel (630), providing corrosion resistance suited to high-traffic openings. It ships as a complete assembly and includes the SK keeper, so the installer has the hardware needed to finish the installation without sourcing separate components.

This electric strike is typically installed on hollow metal frames or aluminum storefront frames in commercial buildings, schools, healthcare facilities, and government installations. The SK keeper configuration is matched to specific door frame and latch geometry, so confirm the door prep and existing hardware before ordering. Access control technicians and licensed locksmiths are the primary installers for this product type.

Installation Notes

Installation should be performed by a licensed access control technician or locksmith familiar with low-voltage door hardware. Disconnect and lock out all power to the access control circuit before beginning work on the strike or wiring. Verify that the door frame prep, latch throw, and keeper geometry are compatible with this strike model before mounting. Local building and fire codes may govern the use of fail-secure hardware on egress paths, so confirm compliance with the Authority Having Jurisdiction before installation.
