You can hear the CA alarms in the background on the transmissions for both SWA and RPA and the controller says nothing. So my guess with the PSA that collided is the controllers are so used to heading the CA alarms they no longer act or respond on them. So when the CA alarms sounded for PSA and PAT25 they didn't think anything of it. It's called "alarm fatigue" and is a MAJOR problem in hospitals where staff hears alarms from devices all day so they ignore them and miss major incidents. Maybe it's time to revisits these helicopter routes in the same proximity of landing/departing commercial airliners.

@VASAviation Agreed, the []onus is on the PAT for maintain VisSep. But when something goes wrong, and a helo deviates off the route or above published altitude and sounds a CA, but the controllers are so used to hearing them they don't even react, that's where the problems can arise. Pretty sure this will be 100% on PAT for fault, but controllers shouldn't be so trained to ignore CAs that this can ever happen again.
