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

Product Description

The HES 310-1 (3/4) 24D LCBMA is a fail-secure industrial-grade electric strike designed for access control applications in demanding commercial and industrial environments. Operating at 24 volts DC, this body-only unit accepts a 3/4-inch keeper and holds the door locked when power is removed - the defining behavior of a fail-secure configuration. The integrated latchbolt locking cam monitor (LCBMA) includes an auxiliary switch that reports latchbolt position back to the access control panel, giving installers a real-time door-status signal without a separate sensor. Licensed electricians and access control technicians are the primary installers of this device.

This electric strike is suited for heavy-use commercial doors such as stairwell entries, utility corridors, loading dock access points, and perimeter doors where a fail-secure posture is required by security protocol. The body-only configuration means it ships without the faceplate or strike box, making it appropriate for retrofit installations where the existing hardware will be reused or where a custom faceplate is already on-site. The auxiliary switch output integrates with most access control panels that accept a dry-contact door position or latch monitor input.

Key Features

• Fail-secure operation: door remains locked on power loss
• 24-volt DC operating voltage for compatibility with standard access control power supplies
• 3/4-inch keeper size for proper latchbolt engagement
• Latchbolt locking cam monitor (LCBMA) provides real-time latch position feedback
• Auxiliary switch output integrates with access control panels for door-status monitoring
• Industrial-grade construction rated for high-cycle commercial and industrial use
• Body-only format supports retrofit and custom faceplate installations

Compatibility

Designed as an OEM-style replacement or new-installation electric strike for commercial access control systems requiring a fail-secure 24-volt DC unit with a 3/4-inch keeper and integrated latch monitor output.

Installation Notes

Installation should be performed by a licensed electrician or certified access control technician in accordance with NFPA 70 (NEC) and applicable local codes. Disconnect and lock out all power to the access control circuit before wiring the strike or auxiliary switch leads. Verify the door frame mortise dimensions and keeper alignment before securing the strike body to avoid binding on latchbolt engagement. Confirm that the access control panel supports a dry-contact auxiliary input before connecting the monitor switch output.
