Help with wiring a siren PA system
« on: July 08, 2013, 02:57:32 PM »
i bought this unit for my UTV
http://www.whelen.com/_AUTOMOTIVE/details_prod.php?head_id=9&cat_id=66&prod_id=455

It is a single unit that came without the PA mic.
I am hoping to bypass the extra $70 cost of the OEM unit and wire in one of my own.

 I am assuming that everything is in the unit and the mic is just an added feature.
Here is the diagram of the unit ipwtih the mic

First off do you think I can wire in a mic like my FT-60r mic and use the PA function?

Second what wiring scheme would you use and what in dash connector would work? 

The only dumb question is the one that did not get asked!!

It looks like you'll need a schematic to get a better answer. The white is probably a ground and the push to talk switch uses it with a resistor to activate the system. The good news is that most any mic will work.

Thanks Temp.  I have spent the day searching the internet looking for the schematic of the inside of the siren/speaker or for a post where someone else did the mod, but No Joy.
