Sargent 8974-G-ETB-12V Mortise Exit Device, Electrified Trim 12V Fail Secure, ET Control, B Lever, For 43-48" Width Door, Hex Key Dogging, No Cylinder, Grade 1

The Sargent 8974-G-ETB-12V is a Grade 1 electrified mortise exit device engineered for secure, access-controlled openings on doors measuring 43 to 48 inches wide. Built around Sargent's ET trim with the B lever design, it operates on a 12V fail secure function, meaning the outside lever remains locked during a power loss while free egress is always maintained from the inside. This configuration is ideal for buildings where controlled entry is a priority, such as offices, institutions, and healthcare facilities. No Cylinder: this configuration has no cylinder override and does not require an override cylinder.

Functional Details

This 12V 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. No Cylinder: this configuration has no cylinder override and does not require an override cylinder.
