Open ckt on the keypad refers to the data lines going to the keypad. check to make sure the yellow and green wires from keypad are properly connected.
This could be caused by a mis-wired zone on the control panel. If there are any unused zones on the panel, and/or if the bell circuit is unused, a resistor ( info in installation guide ) must be used across the terminals or you will get an open circuit message. If you can't see it straight away, have your local alarm company check your system and they can find this fault for you quite easily.
