End of line resistor value is not set correctly. The panel is looking for resistor value set in Global Point Configuration, End of Line resistor value. If not set to Point Doubled, 2.2k & 3.65k , keypad will show "Not Ready". Go to Nibble 1026 and select 4 for Zone doubling.
- Contacts must be closed loop when point doubling.
- Be sure that the 3.65k resistor is used on zones 2-8 and the 2.2k is used on 10-16.
- Point 1 cannot be doubled and always uses a 2.2k resistor.
- Check the zones to make sure they are normal.
