Sargent 12-8874-F-ETB-12V Electrified Fire Rated Rim Exit Device, Fail Secure Power Off Locks Lever, No Cylinder, For 33-36 Inch Width Door, Less Dogging

The Sargent 12-8874-F-ETB-12V is a heavy-duty electrified fire rated rim exit device engineered for secure, code-compliant openings on commercial and institutional doors. Built to fit 33 to 36 inch wide doors, this unit features a fail secure (power off locks lever) electric latch retraction configuration, meaning the outside ETB lever remains locked when power is removed. The 12V design integrates seamlessly with access control systems, allowing remote locking and unlocking of the trim while maintaining free egress at all times. As a fire rated device supplied less dogging, it meets the requirements for labeled door openings where mechanical dogging is prohibited.

Features

• Fire rated construction suitable for labeled openings requiring positive latching.
• Fail secure electrified function locks the outside lever when power is lost for added security.
• ETB escutcheon trim with a durable lever handle for controlled outside access.
• Designed for doors measuring 33 to 36 inches in width.
• Operates on 12V power for compatibility with electrified access control systems.
• Supplied less dogging, as required for fire rated applications.
• No cylinder included, allowing field configuration to match existing keying systems.

Functional Details

The fail secure configuration keeps the outside lever locked whenever power is removed, ensuring the opening stays secure during a power failure. Applying power releases the lever to allow authorized entry, while the inside push bar always permits free egress.

• Fail secure: power off locks lever, power on unlocks lever.
• Free egress is always available from the inside push rail regardless of power status.
• 12V DC operation for integration with access control.

Arm Type Details

This device uses the ETB exit trim, an escutcheon-style lever trim mounted on the exterior face of the door. The lever controls outside access and works in conjunction with the electrified latch to provide locked or unlocked status based on the power state.

Included Components

The device ships as a complete rim exit assembly with the ETB lever escutcheon trim. A cylinder is not included and must be ordered separately to match your keying requirements.
