We were having sensor issues with this siren. It repeatedly claimed motor blower failure after activation. Obviously it works fine.

More blower failure? What's that?

There are two sensors on the wiring to the two motors in the T-128. One on the rotation motor the other on the blower motor (chopper motor). Its assumed that the detected voltages indicate motor function... if the sensors are properly calibrated.

Oh okay. That makes sense.
