What would you test after installing occupancy sensors?

Just after some experienced views!

I was at a job today where microwave occupancy sensors had been installed on tennis courts. I think they are basically glorifed P.I.R.'s.

What certificate would you issue afterwards - minor works as it's just an addition? Would you test at the last light or just from the sensor?

if they have been installed as switching for an existing cicuit, then it's a MWC for the modified circuit. test from the end of the circuit for res. and Zs. for IR testing, either disconnect and link out the PIRs, or short L/N and test to E.
