Yes, the GMS R118-KW1-26D is generally compatible with exit devices that accept a standard 1-1/8" rim cylinder. This model is a 1-1/8" rim cylinder with a standard tailpiece, and GMS-style rim cylinders are commonly used on various exit devices or night latches. The KW1 keyway affects the key blank and pinning, not whether the cylinder fits the exit device.
The important part to note is that there is no guaranteed fit for every GMS exit device without checking the exact model. You still want to confirm that the exit device is designed for a rim cylinder, that it uses the correct 1-1/8" cylinder length, and that the tailpiece/cylinder prep matches the device.
