Hes 310-1 (1/2) 24D Electric Strike Fail Secure 24VDC

Product Description

The HES 310-1 (1/2) 24D is a fail-secure, industrial-grade electric strike designed for 24-volt DC access control applications. In a 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 body-only unit accepts a 1/2 inch keeper and is built to handle the higher cycle demands typical of commercial and industrial installations. Licensed access control technicians and security integrators are the primary installers of this hardware.

This electric strike is suited for commercial and industrial door frames where a fail-secure locking mode is required by the access control design. The 24VDC operating voltage is a standard in most modern access control panel configurations. The body-only format allows pairing with a compatible keeper to match the door hardware already on site. Typical applications include stairwell doors, secure perimeter entries, and interior controlled-access doors in commercial buildings.

Key Features

• Fail-secure operation: strike remains locked when power is removed
• 24VDC operating voltage compatible with standard access control panels
• Industrial-grade construction for high-cycle commercial and industrial use
• Body-only configuration for flexible keeper selection
• 1/2 inch keeper size for precise hardware compatibility

Compatibility

Designed as an OEM-style replacement or new-installation electric strike body for industrial and commercial access control door hardware accepting a 24VDC fail-secure strike with a 1/2 inch keeper.

Installation Notes

Installation should be performed by a licensed access control or low-voltage technician in accordance with applicable local codes and NFPA 70 (NEC) requirements for low-voltage wiring. Always disconnect power to the access control panel before wiring the strike. Verify that the door frame preparation matches the strike body dimensions before mounting. Confirm fail-secure vs. fail-safe requirements with the system designer before installation, as reversing this selection has direct life-safety implications.
