Had a weird voltage drop on a Honeywell Vista 20p install in a 1970s house
I put the main panel in the basement and ran the keypad wire up two floors. The voltage at the keypad was only 8 volts, not the 12 it should be. I learned the old cloth wrapped wire in the walls was causing way more resistance than I figured. Anyone run into this with older buildings and have a good fix besides moving the panel?

Ever notice how old houses just fight you on every little upgrade? That cloth wire is basically a built-in resistor. You might have to run a new, dedicated line for the keypad.
