Dorma F9400B Fire-Rated SVR Exit Device
The Dorma F9400B is a heavy-duty, Grade 1 fire-labeled surface vertical rod exit device for wide-stile wood or metal fire pairs that cannot take a mullion. The F prefix is the fire label, not a function. This page is the factory B rail (36 in door), function 01 Exit Only, default RHR. Panic 9400B is a separate listing.
Grade 1 Strength and Universal Design
Certified to ANSI/BHMA A156.3 Grade 1, the fire-labeled 9400 latches top and bottom so the pair stays clear in the middle. Final hardware must match the opening fire rating and the AHJ.
Advanced Security and Electrified Integration
This F9400B is the fire-labeled mechanical SVR. A published hourly rating and UL file number are not claimed here. The 9000 order block lists factory options including MLR, ES, MS, and LM. Those options are not on this 01 Exit Only page.
Key Product Features
- Fire-labeled F9400: the F prefix is the fire label on the 9400 SVR. This page is that 36 in device, not panic 9400B.
- No hex-key dogging: less dogging is standard on the fire-labeled F9400.
- Grade 1 certified: ANSI/BHMA A156.3 Grade 1 on the 9000 Series certification page.
- Default B + RHR: PL38 -- Size B and RHR are the factory default when not specified.
- Default strikes included: top 426 and bottom 439 on the PL38 9400 order block. SNB thru bolts are standard on fire and hurricane rated devices.
- B rail as shipped: 36 in device (cut-down minimum 28 in). A = 48 in is F9400A.
