Yes I get it !! Electrical interference and the reflection / absorption of radio waves are different things and can be tested for and cured in different ways. I have the information that I need thanks. David

Thanks for everyone's help, I am not trying to spark off arguments between professionals, all of the responses have been helpful to me. I have also found a useful guide:-...

Thanks to all for their comments. It is clear from the responses that there is a risk of interference so I will be following one of the suggestions of putting it in the correct position before final installation with a temporary keyboard link and trying out the signal strength at various...

Is this it ? http://www.wireless-alarms.net/store/customer/manuals/RE3000%20System%20Manual%20Complete_WA.pdf

Thanks everyone for the inputs, I will be putting all of the information to good use in a weeks time. Happy Xmas all

Joe, please tell me if I am wrong as I am just an amateur. Isn't a panic alarm just a couple of normally closed circuits ? If so, can't one just join the 4 cores together using a terminal block ? If that doesn't work join red to black and blue to yellow - I know that is guessing however...

Thanks, I will do a few tests

As I said before I am not getting on a ladder until the summer !! The ladder would be up against the house wall and the bell is on a gable wall at 90 degrees - doesn't look fun.

Thanks, I guess that there is no substitute for try it and see !! I will test on the strobe first so I don't upset the neighbours. Any thoughts on the other question ? <<I will be without a working panel for a couple of days, is it better just to let the sounder ring until the battery dies...

Thanks, something simpler will be better. I am fine with switched negative as a trigger and both options do that, my issue is what should inactive normally be, I seem to have an option of inactive either being an open circuit or positive and I am not sure if that makes any difference in alarm...

Hopefully my final topic on my impending upgrade from a Scantronic 9800 to an ION-40 is about my external sounder. The sounder was fitted 20 years ago & I have no idea of the make as I have a white bellbox with the alarm company logo on it. The internal battery is pretty bad, when I remove...

Thanks EightyTwo - that is great and gives me confidence to dig in the right place. I think that the builder put a thick layer of plaster on after the alarm company had done the first fix - they then kept on getting the alarm company to patch up the mess when the swinging lid caught on the...

Thank you all for your help. I intend to test out the unit before installation so will follow the advice on the signal test, I only have PIRs to test with as I am keeping the existing wiring on the 3 exit doors. The existing box had an unidentified gizzmo with a capacitor that connects to...
