Sargent RX-8271-24V Lnb 32D Electrified Mortise Lock

Product Description

The SARGENT RX-8271-24V LNB 32D is a fail-secure electrified mortise lock designed for commercial door hardware applications requiring controlled access and reliable electrical integration. Operating at 24 volts, it remains locked when power is cut, making it appropriate for security-critical openings where default-locked status is required by code or building design. The unit features an LN rose trim, a B lever style, and an RX request-to-exit switch built into the lever, all finished in satin stainless steel (32D). Licensed locksmiths, commercial door hardware technicians, and electrical contractors typically handle installation and commissioning of this hardware.

This electrified mortise lock is suited for commercial and institutional buildings where access control integration is required. Typical applications include office entry doors, corridor doors, and secured interior openings connected to an access control panel or door controller. The RX switch provides a signal output when the lever is depressed, allowing the access control system to monitor exit activity and suppress door-forced alarms. The satin stainless steel finish suits high-traffic environments where corrosion resistance and durability are priorities.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with electrified hardware and low-voltage wiring practices. Disconnect and lock out the access control power supply before wiring the lock to avoid damage to the RX switch circuit or the door controller. Verify the door prep mortise pocket dimensions match the lock body before installation. Low-voltage wiring must comply with applicable local codes and NEC requirements for access control circuits.
