Narrative:

Following the departure procedure from mmu we were on a 160 degree heading at 2000 ft when we received an RA to descend then followed by a climb. The PNF saw the traffic and took control of the aircraft. The helicopter was a locally based operator and should have been aware of the departure corridor and altitudes at mmu. If the helicopter would have been at 1500 ft or not in the corridor this would have been avoided.
