I have a pr511 set up on A16 so that it will put out an A1 (it wraps around back to 1, 2, 3, 4 when set to 16.) I have just the pr511 motion sensor wired & not the floodlight part. Cap off the wires going to the light. For the floodlight, I have it wired to a ws467 set to A1(but your XPS3 will work the same). HAve both the pr511 and the MS16A only sense motion at night.
I have the ms16A setup for A1
I have the SC546A set to A1
The PR511 senses motion & sends out an A1 (or 2, ,3, 4) ON. In this case the ws467 for the floodlight will turn on and the SC546A will chime.
The MS16A senses motion & does the same as the PR511.
The only problem you will have will be the off command. The PR511 and the MS16A will send the off at different times based upon when they were tripped and the duration you set them to.
You would need anothe MS16A and SC546 both set to a different unit code for the daytime chime.
