The Hurricane was High Maintenance like the Thunderbolt. The Allertor was too. That is the main reason for discontinuation.
What is the definition of "high maintenance?" This has been posted on the board many times.
The Thunderbolt had 3 or 4 checks that the manual said to do once a year.
Check blower oil and belt, check rotator oil and belt and oil the blower air relief valve. Of course most Thuderbolt owners let them go with no service done to them until they quit.
I guess if you compare once a year maintenance to no maintenance then that's high maintenance.
How often do electronic sirens need their batteries replaced? Didn't someone on the board say once that it's every 5 years? If that's the case I would bet that after the numbers were added up the costs of doing once a year checks on a T-bolt compared to replacing all the batteries in an electronic siren every 5 years wouldn't be that much different. Also electronic sirens aren't "maintenance free." There's always stuff going wrong with machinery whatever it is. If Thunderbolts were made today they would be more reliable anyway because of newer sealants, gaskets etc.
I don't know any of the details, but it's easy to see how the Hurricane, like the Thunderbolt, was more complicated and expensive than the alternatives.
That's really what it boils down to. They cost more to make and installing them is more of a pain with the blower etc. Of course they can't be battery backed up and they don't "talk" either.
Dad, what does that CD mean on that big yellow horn? Well son, I believe it stands for Cyclone Device......
