The EPIRB/PLB system is very good, but it was designed in about 1960 to work for ships out in the ocean. It's not envisaged as a fast response system.
Worst of all you don't get two way comms so you can't tell them it's not a false alarm.
I wonder if other outdoor solutions are already better, although you might need to fork out for a subscription:
