Sargent LC-12-8975-G-ETB-24V Fire Rated Mortise Exit Device, Electrified Trim 24V Fail Safe, ET Control, B Lever, For 43-48" Width Door, Less Cylinder, Less Dogging, Grade 1

The Sargent LC-12-8975-G-ETB-24V is a Grade 1 fire rated mortise exit device engineered for high-traffic openings that demand both security and reliable egress. Built for doors measuring 43 to 48 inches wide, this device features electrified ETB trim operating at 24V in a fail safe configuration, meaning the outside lever unlocks during a power loss to support controlled access and life safety requirements. The B lever design offers comfortable operation, while the less cylinder (LC) and less dogging specification allows integrators to tailor the installation to the project. Ideal for commercial, institutional, and access-controlled environments where fire-rated protection is essential.

Functional Details

This 24V DC electrified ET trim operates in fail safe mode. With power removed, the outside lever is unlocked. Applying power locks the outside lever. When unlocked, turning the outside lever retracts the mortise latch. Operating the inside push rail permits egress regardless of the electrical state of the trim. A compatible mortise cylinder, ordered separately, provides mechanical key override.
