Voice Alert With 1 Transmitter

I tried to contact California (original owners) just today and my 'malware program', i.e., Malwarebytes does not allow me to go further saying if I connect to their site I may get malware on my computer? Something is not right but anything having to do with Africa today is a risk for computers. The system is good, had some very annoying technical issues with the battery connections (if changed battery more than twice connections failed. I think they corrected that problem?

Its an incredible piece of electronic early warning equipment !!! I just found a vendor for this device with more sensors available stateside with the franchise for the equipment!! Bad news...my equipment came with NO INSTRUCTIONS OR PAPERWORK OF ANY KIND!!! The new unit had everything!!!
