The "LM" and "DM" options are no longer available for the 24-R panic device because it now has deadlocking standard (as of April 1, 2017).
Before April 1, 2017 it was available on a 24-R with the "LM" or "DM" option because deadlocking was not standard at that time.
The "LM" and "DM" options were never available on the F-24-R fire rated device.
