I can't hear my Galls street Thunder siren model xs100.

I can only hear a little bit of sound kind of a whining noise from the inside of the siren itself. It was wokring fine and the 100 watt speaker was outputing the sound for about 5 mintues until all of a sudden it stopped. all connections are good. what else? the speaker cannot be blown because its brand new and its what the siren calls for. (100 watts) Can anyone help me?

The systems is working fine and no indications or warnings on the panels, but you can hear the siren at a low sound at all times. All the zones are working according to the panel and alarm monitoring...

The siren should not receive any power when in idle mode (non alarmed state). If you hear any noise, it receives some kind of low voltage. Is it powered straight from the panel or with external power supply and aux. relay? In any way - use a volt meter and measure across the sirens power terminals. If you have any voltage present check the source.

Because the whine is still happening at high speed when your in neutral and low rpms it should not be engine or tranny related. I would start looking at wheel related issues. Hubs probably.

The remote or Aux input does not work on my Galls Street Thunder xs100. I hooked up a switched ground lead, no result. I hooked up a switched positive lead, no result. Any ideas??

What do you mean you hooked up a switched lead? There are inputs for voltage, outputs for speaker, a connection for the horn ring and a set of terminals to hook up the output of a radio to.

Siren nosie from engine

sounds like a power steering issue. They whine when the fluid is low. Check your fluid level. If it is low, you have a power steering leak. If its not that, describe the sound a little more and I'll try again.

Sounds like you have a tuner or intermediate frequency amplifier problem. This would be on the main board. The tuner is were the coax connector is hooked up. I would change the main board that has the tuner on it. The intermediate stage (amplifiers) will be on this board as well. Did the set get wet? If moisture got in the tuner it will act the way you described.

After flushing flusmate toilet a very loud siren-like sound occurs.

Try changing the opening of the water valve that feeds the toilet... just open the valve a little bit, try again, if noise is still there try closing it a bit... the noise is probably from the water valve vibrating and changing the position often will eliminate it. The valve should be obvious, it's what the water supply line from the toilet connects to.

My audi a3 2.0 tdi has a siren noise when driving it.

It's most likely the turbocharger. We used to have an Audi with a turbo and it had a bit of a whine when accellerating. A slight siren type of noise is normal for it, but, if it's real loud then it should be checked.

Give me model number (it is on back and also should be on right side of cabinet)

I suspect it is a DLP set with a bad color wheel.

Wheel faces lamps in DLP type sets and bearings in motor fail causing either high pitched whine/fan like sound.

If wheel shatters set will shut down.

There are instructions and videos on You Tube for replacement of the kind of part---do it your self repair.

Look at photo and add comment here with model number.

If this told you something you did not know rate this solution as very helpful as I do this here for free.
