OK mark U got the deal.There are plenty of videos on youtube if you search for police siren. I quite like the French one. UK ones sweep up and down which is a touch more complicated to program but more fun.
I could be interested in helping out. I've got plenty of time on my hands at the moment.

I donno whether u will touch my money or not but do PM me ur postal address. I always show gratitude towards those who have helped me.
What can you do actually?
What I want is a siren code for a PIC, This PIC will also be used to flash the LED's which I made before, and also it will monitor the siren battery charge rate. Which is a 12V 7A SLA.
I am familiar with PIC mikro MPLAB IDE.
I can modify any code written in this language.
I would go for a surface mount device if possible to make the circuitry smaller and a big headache for any one trying to steal my idea.
With tht battery I can get around 80W for an hour or so, This place is small so, police siren won't last even 30min. I have to boost the output to drive a 100W bull horn which I have checked around.
So for now these are the things I like to clarify.
On coming Saturday I will be meeting with Police staff in charge together with the contractor. I have to explain them the limitations and options available to the Cycle they had in mind.
I will show them options on the type of tone. Only they can finalize what type of tone they want.
