The Sargent LC-12-NB-8713-F-ETJ-84 is a fire-rated surface vertical rod exit device built for demanding commercial openings that require dependable egress and classroom-level access control.

This configuration ships less cylinder for flexible keying and less bottom rod for a cleaner look and reduced maintenance at the floor. With no dogging and an integrated thermal pin, it meets fire-rated requirements while delivering long-term reliability.

Functional Details

The classroom function (12) allows the outside lever to be locked and unlocked using a key, while free egress is always available from the inside by pressing the push bar. As a fire-rated device, it is supplied without mechanical dogging so the latch remains active to meet labeled door requirements.

Arm Type Details

This unit uses the ETJ lever trim, a return-style lever designed for classroom applications. The lever retracts the top latch when unlocked, and key control at the trim governs whether outside access is permitted.
