The 252L is only available in L (classroom) or L-BE (passage) functions and cannot be converted or setup for a Nightlatch (L-NL) function.
This device and trim was designed for a specific code application that requires the trim on a pool enclosure be located at 54" if the trim is not automatically locked. Meanwhile, the Exit Device still needs to be mounted at a lower height (16" - 18" below the lever).
If a Nighlatch (NL) function is desired with the 98/9952 Pool Gate Device, order the 98/9952 Pool Gate Device as EO (Exit Only), then order a standard 98/99 Series NL Trim for Rim/Vertical devices (990NL-R/V or 996L-NL-R/V) on a separate line to be installed together in the field.
