Hes 310-2 3/4OB 24D 630 Electric Strike 24VDC Fail Secure

Product Description

The HES 310-2 3/4OB 24D 630 is a fail-secure electric strike designed for access control applications on double doors that do not use a coordinator. Operating at 24 volts DC, this complete strike assembly holds the door locked when power is off and releases only when energized. The open-back design allows the latchbolt to pass through without a standard back plate, making it compatible with double-door configurations where a coordinator is not present. The satin stainless steel finish provides corrosion resistance suited to commercial and institutional environments. Licensed access control technicians and commercial door hardware installers are the typical trade for this unit.

This electric strike is intended for commercial and institutional entryways where fail-secure operation is required by code or security policy. The open-back configuration is specifically suited to pairs of doors - such as double-leaf aluminum storefront or hollow metal frames - where aligning a standard strike with a coordinator is not practical. The 3/4 inch keeper depth accommodates standard latchbolts on mortise or cylindrical locksets used in these assemblies. It is commonly installed in office buildings, schools, healthcare facilities, and secured entryways controlled by card readers or intercoms.

Compatibility

Designed as an OEM-style replacement or new-installation electric strike for double-door assemblies in commercial access control systems that operate at 24 volts DC and do not use a door coordinator.

Installation Notes

Installation should be performed by a licensed access control technician or commercial door hardware installer familiar with low-voltage wiring practices and local building codes. Disconnect and lock out all power to the access control panel before wiring the strike. Confirm the door frame mortise dimensions match the strike footprint before cutting or modifying the frame. Wiring should comply with NEC Class 2 low-voltage circuit requirements where applicable.
