Hes 742-75 24D 630 Electric Strike Fail Secure 24VDC

Product Description

The HES 742-75 24D 630 is a fail-secure electric strike designed for metal frame door applications requiring controlled access. Operating at 24 volts DC, this complete strike unit holds the door locked when power is removed and releases only when energized, making it well suited for security-critical entry points. The 3/4 inch keeper profile fits standard metal frame cutouts. Finished in satin stainless steel, the unit resists corrosion and wear in high-traffic commercial environments. Installation is typically performed by a licensed locksmith, access control technician, or low-voltage electrician.

This electric strike is used in commercial and light industrial access control systems where a fail-secure function is required. Fail-secure operation means the latch remains locked during a power outage, which is standard practice for server rooms, restricted corridors, and secured entry doors. The unit installs into a standard metal door frame strike pocket and connects to an access control panel, keypad, or card reader that supplies 24VDC. The complete kit includes all necessary strike components for a direct installation.

Installation Notes

Installation should be performed by a licensed locksmith or qualified low-voltage access control technician in accordance with local codes and NFPA 70 (NEC) requirements for low-voltage wiring. Disconnect and de-energize the access control system before wiring the strike. Verify that the power supply output matches the 24VDC requirement before applying power. Confirm fail-secure vs. fail-safe requirements with the authority having jurisdiction before installing on any fire-rated or egress door assembly.
