The TSUC1 is a great siren with your choice of 100 or 200 watt capabilities.
I comes standard with the "brain box", backlit controler, and 20 feet of extention cable.
It has the standard wail, yelp, and high low, air horn, PA and now has an additional "interclear" that
is a sound that clears traffic like no other.
The unit also allows you to control 2 separate light functions.
All this in a super small palm sized controler.
