Sargent 12-56-8873-J-ETB-12V Electrified Fire Rated Rim Exit Device, Electric Latch Retraction, Fail Safe Power Off Unlocks Lever, No Cylinder, For 37-42 Inch Width Door, Less Dogging

The Sargent 12-56-8873-J-ETB-12V is a heavy-duty electrified rim exit device engineered for fire-rated openings that require secure, controlled access. Built for doors measuring 37 to 42 inches wide, it features electric latch retraction (ELR) that uses a quiet motor to withdraw the latch for remote release and access control integration. The 8873 function provides exit only with a thumbpiece (ETB) lever trim on the outside, operating in a fail-safe configuration where a loss of power unlocks the lever. Supplied without a cylinder and less dogging to maintain fire-rating compliance, this device delivers reliable performance in demanding commercial environments.

Features

• Electric latch retraction allows remote unlatching and smooth integration with access control systems.
• Fire-rated construction suitable for labeled openings where dogging is not permitted.
• Fail-safe operation unlocks the outside lever when power is removed.
• ETB lever trim provides keyed or non-keyed exterior access depending on configuration.
• Sized for wide doors spanning 37 to 42 inches.
• Operates on 12V DC power for compatibility with common low-voltage systems.
• Rugged all-metal chassis for high-traffic durability.

Functional Details

The 8873 is a fail-safe electrified latch retraction function. When energized, the latch retracts via an internal motor; when power is removed, the latch extends and the outside lever becomes operable for fail-safe egress and entry control.

• Electric latch retraction (ELR) retracts the latchbolt electrically for remote operation.
• Fail safe: power off unlocks the outside lever.
• Exit device provides free egress at all times from the inside.

Arm Type Details

This is a rim-mounted exit device with ETB lever trim. The ETB (Thumbpiece) trim mounts on the exterior face of the door, allowing controlled entry while the push bar on the interior permits immediate egress.

Included Components

The device includes the rim exit chassis, ETB lever trim, and electric latch retraction module. Cylinder is not included and must be ordered separately if required.
