Hes 310-4-2 24D 630 Electric Strike Fail Secure 24VDC

Product Description

The HES 310-4-2 24D 630 is a fail-secure electric strike designed for double-door applications using a PK keeper configuration. Operating at 24 volts DC, this strike remains locked when power is removed, making it appropriate for security-critical access control installations. The 5-inch center-to-center (CTC) dimension suits standard commercial door prep, and the satin stainless steel finish provides corrosion resistance in high-traffic or exposed environments. Licensed electricians and access control technicians are the primary installers for this type of hardware.

This electric strike is intended for commercial and light industrial access control systems where a double-door configuration requires a fail-secure locking solution. The PK keeper design accommodates specific latch bolt geometry common in commercial door hardware. The 5-inch CTC measurement must be matched carefully to the door frame prep before ordering. Applications include office entry doors, stairwell doors, and other controlled-access openings that require the door to remain locked during a power interruption.

Key Features

• Fail-secure operation - door remains locked when power is cut
• 24 volts DC operating voltage for compatibility with standard access control panels
• Double-door configuration with PK keeper design
• 5-inch center-to-center (CTC) dimension for standard commercial door prep
• Satin stainless steel (630) finish for durability and corrosion resistance

Compatibility

Designed as an OEM-style replacement or new-installation electric strike for commercial double-door frames with a PK keeper latch and a 5-inch CTC door prep accepting a 24-volt DC access control system.

Installation Notes

Installation should be performed by a licensed electrician or certified access control technician in accordance with NFPA 70 (NEC) and applicable local building codes. Disconnect and lock out all power to the access control panel before wiring the strike. Verify door frame prep dimensions, particularly the 5-inch CTC measurement, before installation. Confirm that the fail-secure mode is appropriate for the occupancy type and complies with local fire and life safety codes.
