Sargent 12-55-8813-J-ETB Fire Rated Rim Exit Device, Classroom Function, Request To Exit, ET Control, B Lever, 37"-42" Door Width, Less Dogging, Grade 1
The Sargent 12-55-8813-J-ETB is a Grade 1 fire rated rim exit device built for demanding classroom applications on doors measuring 37 to 42 inches wide. It pairs classroom (8813) function with the ETB trim set, featuring the B lever and J escutcheon design, giving staff reliable keyed control of outside access while maintaining free egress at all times. The integrated Request to Exit (RX) switch provides a monitored signal for access control and alarm systems, making this a smart choice for secured corridors and institutional environments. As a fire rated device, it ships less dogging to meet code requirements for openings that need positive latching.
Features
- Grade 1 rated for heavy-duty commercial and institutional use.
- Fire rated construction suitable for labeled fire door assemblies.
- Classroom (8813) function allows keyed control of the outside lever.
- ETB trim with B lever and J escutcheon for a durable, ADA-friendly grip.

Functional Details
The 8813 classroom function keeps the exit device latched from the outside, where the key retracts the latch for momentary entry. The inside push bar always releases the latch for immediate, unimpeded egress. The 12 prefix adds a factory-installed Request to Exit switch that sends a monitored signal whenever the push bar is depressed.
- Key retracts latch bolt; key removable in locked or unlocked position.
- Outside lever is always rigid; latch retraction only by key.
- Push rail dogging not provided on fire rated devices.
Arm Type Details
This is a rim-mounted exit device, meaning the mechanism and latch install directly on the surface of the door and strike on the frame. The single-point rim latch engages a surface strike for straightforward installation and dependable fire door latching.
Included Components
The device ships with the rim exit chassis, ETB classroom trim including the B lever and J escutcheon, surface strike, the factory-installed Request to Exit switch, and mounting hardware.
