    This lock is not compatible with a panic bar. Kaba does make a lock that is however. Take a look at the Simplex LP1010. You'll want to be sure your panic bar model is on the compatibility list. If not, we have offer the exit bars and can show you a couple of options. Connecting the bar to the lock is straightforward, instructions are provided.
