Sargent 12-56-8873-F-ETB-12V Electrified Fire Rated Rim Exit Device, Electric Latch Retraction, Fail Safe Power Off Unlocks Lever, No Cylinder, For 33-36 Inch Width Door, Less Dogging

The Sargent 12-56-8873-F-ETB-12V is a fire-rated rim exit device engineered for high-traffic commercial openings that require electrified access control. Built with electric latch retraction (ELR), it allows the latch to be pulled back remotely for momentary or sustained free access, while its fail-safe design unlocks the lever on power loss to support emergency egress and secure building operation. Configured for 33 to 36 inch wide doors, this device pairs the 8800 series rim chassis with the ETB lever trim and runs on 12V power. As a fire-rated unit, it ships less dogging to meet code requirements for fire door assemblies.

Functional Details

The 56- prefix designates electric latch retraction, which uses an internal motor to retract the latch bolt electrically. This enables remote unlocking from an access control system, scheduled free entry during business hours, and automatic relocking on command, all while preserving mechanical free egress from the inside.

• Electric latch retraction (ELR) retracts the latchbolt electrically for remote access control.
• Fail-safe: outside lever is unlocked when power is off.
• Compatible with automatic operators for low-energy and full-powered openings.

Arm Type Details

This device uses the ETB escutcheon lever trim, a through-bolted night latch function trim with a return-style lever that meets accessibility guidelines. The lever controls retraction of the latch for outside entry, while the inside push rail always permits free egress.

Included Components

The device ships as a complete rim exit assembly with the 8800 series chassis, ETB lever trim, and electric latch retraction hardware. A power supply and cylinder are sold separately.
