The low frequency pitch is important to pierce the sound-deadening designs of today's vehicles. I've seen many of these sirens get passed from build to builds many times!
Black Hoe said:Hey Wailer, you are always repeating yourself on your posts. You do nothing but criticize Unitrol Sirens especially their wail tone. The truth of the matter is there are alot of members on here including myself that like the sound of Unitrol sirens. They are extremely effective at clearing traffic and intersections and are probably one of the most reliable electronic sirens manufactured today. I have been running Unitrol 80K's, Omega 90's and Touchmasters (not Deltas) for 30 years now and can speak for their reliability. I never had one burn out yet.

The 480K is part of a family of controllers that hooks up with the 80K amplifier either by a remote cable or bolted together in one unit (requires an extended chassis that houses both the controller and the amplifier).
The beauty of the 80K is the flexibility. You can control the siren with your own switches, just one or a combination of several.
