Hes 310-1 (3/4) 24D Electric Strike Fail Secure 24VDC

Product Description

The HES 310-1 (3/4) 24D is a fail-secure industrial-grade electric strike designed for access control applications in commercial and institutional door hardware installations. Operating on 24 volts DC, this strike remains locked when power is removed, making it the correct choice for security-critical openings where locking on power loss is required. The unit is sold as a body-only assembly and includes a 3/4 inch keeper, suiting installations where the existing frame hardware is retained or a matching keeper is sourced separately. Electricians and access control technicians are the primary installers of this type of hardware.

This electric strike is intended for industrial-grade door access control systems, typically installed in commercial buildings, industrial facilities, and institutional environments. It is suited for applications where fail-secure operation is a code or security requirement, such as server rooms, secure corridors, and controlled-access entryways. The body-only configuration makes it appropriate for retrofit projects where the frame prep already exists or where only the strike body requires replacement.

Key Features

• Fail-secure operation - strike locks when power is removed, maintaining door security during outages
• 24 volt DC operation for compatibility with standard access control power supplies
• Industrial-grade construction for high-cycle, demanding commercial environments
• Body-only configuration supports retrofit and replacement installations
• 3/4 inch keeper accommodates standard commercial latch bolt geometry

Compatibility

Designed as an OEM-style replacement or retrofit electric strike body for industrial-grade commercial access control door hardware applications requiring a 3/4 inch keeper and 24 volt DC fail-secure operation.

Installation Notes

Installation should be performed by a licensed electrician or certified access control technician familiar with low-voltage door hardware systems. Power to the access control panel and strike circuit must be shut off before wiring or mounting work begins. Follow all applicable NEC requirements for low-voltage wiring, and verify that the door frame prep matches the strike body footprint before installation. Confirm fail-secure versus fail-safe requirements with the authority having jurisdiction before final commissioning.
