I haven't heard them, but they do answer e-mails. Ask which one is most appropriate.
I'd assume you can replace a slide switch with a button. It should make no difference.
You could put a resistor between the module and the speaker if it's too loud and there's no other way to do it.
When I get to that point, I'll probably try a couple of these. For the price, even if it doesn't work out, it's an experience.

I looked on the bakatronics site, and they advertise a 'super siren'. is this an appropriate sound for an air raid bunker or is it something else?
also, ndbprr raises a good point, can I adjust the volume of these things?
and can I add a button switch or will they only work with the slide switches?

They have a harbor, city, and roundhouse WWII soundtrack CDs in there. Convert this to .wav using windows media player, put it on a SD card, and plug it into a DreamPlayer. You can add an air raid siren to track two, and have it play with a momentary push button press on the front panel.

These guys have several kits for sirens. Look under "Sound Effects Kits."

I've never tried them, but they do respond to e-mails.
Saen,
There are lots of ways of doing this. An electronic siren available from one of the electronic hobby shops would probably be the best, but you could use a cheap MP3 player with a small speaker plugged into the headphone jack and download an appropriate wave file, or you could use a sound effects CD. Another option is to gut one of those model cars that have sounds (emergency vehicles such as police or Fireengine), there's a Yahoo group that deals in model railroad sound effects, you could ask them.

does anyone know of a good way to get sound effects into a layout, preferably with a really small speaker? I just converted an unused lineside hut into a WW2 air raid shelter, and it would be pretty neat if i could have a button that would make the siren sound. is there any way of doing this? perhaps some sort of sound module which you could install short sound files onto from a computer and with one of the speakers from a dcc sound chip for inside locos? and does anyone know where i could get the actual siren sound file?
thanks,
Sean
