Alarm trouble I have a ademco Vista-15p alarm panel with a 6150 key pad. I hooked it up for the first time and the key pad reads oc for open circut. I checked all the wiring and its good and in the right order. I cannot do any thing with the key pad until I get past this point. can you get a solution for me

Could be an unseen break in the wire or a loose connection, OR:

This also happens when the alarm panel power circuits work but the micro-chips are fried... This is almost ALWAYS is the case when a panel is the victim of a lightning strike that hit the phone line it was connected to..

If this panel was new in the box, then check to see if the chip with the white sticker on it is right side up and fully seated in its socket on the main board.

You could also check the OHMs on the wires. If you have over 100 Ohms on the keypad wire it will likely cause a fault in the data signaling resulting in "OC" on the keypad.

Good Luck testing it out!

OC means a wiring problem between the keypad and the alarm. Take the keypad and hook it up in the alarm cabinet and see if it works there.
