System doesn't work, no response to calls
This system has never worked. I called shortly after I received the system and set it up and received some bogus advice to renumber one of the units. I made another call to American Alarm Systems who provides the merchandise and support for American Bulldog and was referred back to a voicemail phone and have low expectations of a return call. I have also sent several emails to AAS and did not receive a reply. This company is selling equipment that does not work and is defrauding customers. BEWARE!
