That's exactly the issue with most of the new apparatus and the question boils down to who's fault is it? Is it the fire departments, the government, ISO or?
I'd say any number or combination of the above and then some. You could throw NFPA in their also. Most of the committees are made up of the manufacturers. They come up with an idea, good bad or otherwise, and suddenly every unit coming off the production line has to have this widget. I will say in some ways this is good, such as ropes and most testing procedures. Having a maker say after x amount of years the rope should move from life safety to general purpose is probably a good thing. On the other hand, having to pump test a unit, with every light on, and the climate control system on, and hold everything for an hour, because 1 person on the committes, had 1 unit that had electrical issues at a fire, 1 time in 30 years, is a little excessive. And yes, that was a first hand account.
We had an engine, a 98 E-One Cyclone, we called the widow maker. Because that unit, would do 1 of 2 things. Either you would step on the federal switch, pull the air horn and turn all at the same time, in which case the transmission would stick in what ever gear you were in while responding, or if you made it to the fire with out incident, while pumping the unit would suddenly throttle down and wouldn't come back up. In both cases, the only way to resolve the issue was to shut the unit down, and restart it. After.months of trouble shooting, we finally found out, from an E-One engineer, to check the road to pump safety buried in the transfer case. Sure enough, when we replaced that sensor, both issues went away. Apparently, according to the engineer, the sensor wasn't bad, but wasn't good either. It would test out fine, but for what ever reason., would go stupid.
By comparison, we also had a 71 Pierce 85' Snorkel. I loved thay truck. Never had a problem with that truck. Only issue, and this was specific to snorkels apparently, was every once in a while, while the hydraulics were engaged and the boom was flying, power would be sent to the drive axles and they would spin. Sometimes hop the truck. But alot of other Snorkels did the same. The aerial that replaced it, we had all sorts of problems with the electronics, jack leg sensors and hydraulics.
