Sargent RX2870-10G71-12V Ll 26D Electrified Cylindrical Lock

Product Description

The SARGENT RX2870-10G71-12V LL 26D is an electrified cylindrical lockset configured for fail-secure operation at 12 volts DC. In a fail-secure configuration, the lock remains locked when power is removed, making it appropriate for doors that must stay secured during a power outage. The unit features an LL design lever trim, is prepped for Small Format Interchangeable Core (SFIC) cylinders, and ships less core so the installer supplies the core separately. An integrated RX switch provides door-position or latch-position monitoring for access control systems. The finish is Satin Chrome (26D). Licensed locksmiths, access control technicians, and commercial door hardware installers are the primary trades for this product.

This electrified cylindrical lock is suited for interior and perimeter doors in commercial and institutional applications where access control integration is required. Typical installations include office suite entries, server room doors, healthcare facility corridors, and education facilities where card readers, keypads, or other low-voltage access control devices must control door locking. The SFIC prep allows facility managers to rekey using a small-format interchangeable core system without replacing the lockset body, a common requirement in large commercial keying programs.

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control technician familiar with commercial door hardware and low-voltage wiring practices. Disconnect and lock out all power to the access control system before wiring the lock to prevent damage to electronics or unintended locking cycles. Verify that the supplying power source is rated for 12 volts DC and sized appropriately for the number of locks on the circuit. Confirm local AHJ requirements and applicable fire and life-safety codes before installing fail-secure hardware on any path of egress.
