I recently purchased a 3 year old house with a security system. The previous owners left the User Guide for the "Ademco Vista Series" system. It covers Vista-20P, Vista-20PSIA, and Vista 15-P (I don't know which one I have).
The previous owners DID NOT leave any codes. The keypad is completely blank. The transformer and battery inside the control panel are plugged in. I read online that I should unplug the transformer and battery for a few days, then plug back in, and within 50 seconds hold down (* + #) on the keypad. I've done this several times, but nothing happens. Again, the transformer and battery are plugged in, but the keypad is totally blank. Does anyone know what to do? How do I get this working?
Thanks!!
