Can anyone help? I've got this alarm system with sensors inside that sets off the inside alarm with movement, but there is an alarm box outside that seems to go off for no reason, mainly at night, and makes this awful high pitch noise, and i don't know why it goes off, or how to turn it off. I just have to let it cut off itself after 20 minutes or so. I thought that they were both connected together (if the alarm triggered, both would go off). Any ideas anyone?
