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

The Sargent LC-12-8975-G-ETB-12V is a Grade 1 fire rated mortise exit device built for high-traffic commercial and institutional openings measuring 43 to 48 inches wide. This electrified version operates on 12 volts and uses a fail safe function, meaning the outside trim unlocks when power is removed to support secure egress and emergency access planning. It ships with the ETB electrified trim featuring the B lever design, and comes less cylinder for flexible keying and less dogging as required for fire rated applications. As a mortise device, it delivers the durability and positive latching demanded by heavy-use doors while meeting fire door assembly requirements.

• Electrified 12V trim with fail safe operation for controlled access and reliable egress.

Functional Details

This 12V 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.

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 includes the mortise exit chassis and the ETB electrified trim with B lever. It is supplied less cylinder and less dogging, so a mortise cylinder must be ordered separately to complete the installation.
