The Whelen 295HFRS4 siren amp- can it be controlled with regular switches? I've seen a bunch for sale at great prices but they connect to the controller with only 3 wires, making me think that the controller is needed to make the siren work.
 
i know that this is a VERY old thread...... but i am wondering the very same thing today.


Anyone shed some light for me?
