TA/RA in Agusta 109SP TRD-94 Transponder

[chr]

Hi
just wondering last time , TRD-94 Transponder in A109SP is TCAS II compliant , helicopter is also equiped with TAS 630 , so why those two wouldn't give you TCAS RA messages ?
It's deactivated ?

A TAS630 is not a TCAS II. It is a traffic advisory system which can provide only Traffic Advisories (TA).

Only TCAS II would be able to provide Resolution Advisories (RA), but they're pretty rare on helicopters.
