Yes, TCAS II warns all the way down to 100m AGL (around 320ft above the ground), and they were already between 1000ft and 1500ft (~400m).
It may or may not have advised what to do (to climb/descent/etc.) because that is turned off below 1000ft, and they were approximately at that altitude at the time.
