The Sargent LC-12-8976-F-ETB-24V is a Grade 1 fire rated mortise exit device built for high-traffic commercial openings on doors between 33 and 36 inches wide. This electrified version operates on 24V with a fail secure function, meaning the outside trim stays locked during a power loss while free egress remains available at all times from the inside. It features the ETB trim with the B lever design and ships less cylinder, allowing you to pair it with your preferred mortise cylinder. As a fire rated device, it comes less dogging to meet code requirements for fire door assemblies, making it a dependable choice for exit and security control.

Functional Details

This 24V DC electrified ET trim operates in fail secure mode. With power removed, the outside lever is locked. Applying power unlocks 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.

Trim and Lever Details

The ET trim has a B lever. Electrical power controls whether the outside lever is locked or unlocked; operating an unlocked lever retracts the latch. Select the LHR or RHR handing to suit the opening.

Included Components

The device ships with the mortise exit chassis, ETB electrified trim with B lever, and mounting hardware. A compatible mortise cylinder must be ordered separately.
