The dampers are probably set to do that so that small animals and debris cant get into the intake ports.
If I'm correct, a Federal Signal 3T22 has its dampers closed when it is not in use and then when the motor recieves a current, the dampers automatically open depending on the cycle it is set to do (I'm just assuming because I always hear the metal clanking sound when they go off).
That'd be cool to somehow wire the siren so that you could have individual control of both of the dampers or find a way to code the dampers like an AF timer would.
