Sargent RX28-10G71-24V Ll 26D Electrified Cylindrical Lock

Product Description

The SARGENT RX28-10G71-24V LL 26D is a fail-secure electrified cylindrical lockset operating on 24 volts DC. In fail-secure mode, the latch remains locked when power is removed, making this unit appropriate for access-controlled doors where security must be maintained during a power interruption. The LL design designates the lever trim configuration, and the RX switch provides request-to-exit signaling to the access control panel. The satin chrome (26D) finish suits commercial interior and exterior door applications. Installation and service are typically performed by licensed locksmiths, access control integrators, or commercial door hardware technicians.

This lockset is suited for commercial access control applications where cylindrical-prep doors require electrified hardware. Typical installations include office entry doors, stairwell doors, and controlled interior passages in commercial and institutional buildings. The RX switch output integrates with access control systems to signal door activity and support REX (request-to-exit) compliance. The 24-volt operating voltage aligns with standard low-voltage access control power supplies commonly used in these environments.

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control integrator familiar with commercial door hardware and low-voltage wiring practices. Disconnect and lock out all power to the access control panel and door hardware circuit before beginning installation or service. Verify that the door prep matches the cylindrical bore and cross-bore dimensions required by this lockset before mounting. Wiring connections to the access control system should comply with applicable local codes and the NEC for low-voltage installations.
