just installed a 734 module on DMP XR500N panel. door has rim strike with a push bar, rte above the door as well as dr contact. the instructions say that you can set zone 3 for REX input that will activate soft shunt, as well as not energize the unlock relay, i can't figure out to program the module to not energize the lock relay upon REX activation. looked at the programming on the Xr500 panel, but can't find any settings there either.
