Hi, I know this is very rare on this site but I thought I would give you an update. I set the front sounder on slow and the sound does seem to travel a bit further than it did. the slow also sounds pretty cool as well and gives a decent punch to the ears.

Now the one at the back on the fast and you were right the faster tone is a lot more aggressive and really deafens you close up. Thats a good set up I think because the intruder will most likely come in from the back and hopefully that awful tone will drive them away with the help of the internal sounder.

Anyway thanks again, that's me done experimenting with my alarm for now. hopefully the neighbors will come round, they are a bit pissed off with me just now.lol

anyway cheers
