Sargent 12-55-8813-G-ETB Fire Rated Rim Exit Device, Classroom Function, Request To Exit, ET Control, B Lever, 43"-48" Door Width, Less Dogging, Grade 1

The Sargent 12-55-8813-G-ETB is a Grade 1 fire rated rim exit device built for demanding commercial openings where secure egress and reliable access control are essential. Designed for doors ranging from 43 to 48 inches wide, it pairs classroom function (ET trim with the B lever design) with a built-in Request to Exit switch that signals when the device is operated. As a fire rated unit, it comes less dogging to maintain positive latching required on fire-rated doors. From schools to office buildings and healthcare facilities, this exit device delivers dependable life-safety performance backed by Sargent's proven durability.

Features

  • Grade 1 rim exit device rated for high-frequency commercial and institutional use.

  • Classroom function allows the outside lever to be locked or unlocked by key while egress is always free from the inside.
  • Integrated Request to Exit (RX) switch monitors device activation for access control integration.
  • Sized for wide doors measuring 43 to 48 inches.
  • Supplied less dogging, as required for fire-rated applications.
  • ET trim with the B lever offers a clean, durable lever design.

Functional Details

The classroom function (55) lets the outside lever be locked and unlocked with a key, while the inside push rail always allows free egress. The 12 prefix indicates the integral Request to Exit switch, which provides a monitored signal whenever the device is pushed.

  • Outside lever controlled by key; inside always allows free egress.
  • Request to Exit switch signals operation of the exit device for monitoring and access control.

Arm Type Details

This unit uses Sargent's ET (G) trim with the B lever. The lever retracts the latch to provide access when the outside trim is unlocked, delivering smooth operation and ADA-compliant usability.
