Sargent 12-56-8873-F-ETB-24V 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-24V is a heavy-duty electrified rim exit device built for fire-rated openings that demand reliable access control. Featuring electric latch retraction (ELR), it allows the latch to be remotely withdrawn for momentary or sustained free access, making it ideal for schools, hospitals, and commercial buildings integrated with card readers or automatic operators. The fail-safe design unlocks the ETB lever trim when power is removed, supporting code-compliant egress during emergencies. Rated for doors 33 to 36 inches wide and operating on 24V, this device ships less cylinder and less dogging, as mechanical dogging is not permitted on fire-rated hardware.

Features

• Electric latch retraction allows remote, momentary, or sustained retraction of the latchbolt for controlled access.
• Fire-rated construction suitable for labeled door and frame assemblies.
• Fail-safe operation unlocks the lever trim when power is interrupted.
• ETB escutcheon lever trim provides durable keyed or non-keyed access from the pull side.
• Sized for doors measuring 33 to 36 inches in width.
• Operates on 24V DC power for integration with access control systems.
• Furnished less dogging in compliance with fire door requirements.
• Supplied less cylinder, allowing use of a preferred cylinder brand or keyway.

Functional Details

The 56 electric latch retraction function uses an internal motor to withdraw the latchbolt electrically, permitting hands-free passage when energized. When power is cut, the latch returns to its secured position while the fail-safe lever trim remains unlocked to ensure safe egress and entry during a power loss.

• Electric latch retraction (ELR) for momentary or continuous latch hold-back.
• Fail-safe: power off unlocks the lever trim.
• Compatible with access control, automatic operators, and remote release systems.

Arm Type Details

This device uses the ETB escutcheon lever trim, a robust pull-side trim designed to coordinate with the exit device for controlled entry. The ETB trim mounts to an escutcheon plate and provides lever operation that follows the electrified fail-safe behavior of the unit.

Included Components

The device ships as a complete rim exit device assembly with ETB lever trim and integrated electric latch retraction hardware. A cylinder is not included and must be ordered separately to match the application.
