No it's not haunted. I put a battery in it to start it every few months and the alarm keeps going off every few minutes. I can turn the alarm off by hitting the remote unlock button, but 2 minutes later it starts up again. Also, does the siren have a backup battery and could it cause this? After 16 years it must be pretty wasted. When I disconnect the 12 volt battery it still sounds off faintly. And where would it be located so I can unplug it before bringing it home and not annoy the neighbors?
