The tamper circuit is probably irrelevant to the immediate problem.

3 possibilities
i) it's bypassed at the control box with a link
ii) it's wired in series with the existing (first) remote keypad
iii) it's wired in parallel with the existing remote keypad

If the main control panel is not complaining about a missing keypad then
none of the above are causing the problem.

Ideally it should be wired as ii) but possibly not too important with a
remote keypad because in someone cuts the wires to a remote keypad they
still wouldn't have means to turn off the alarm from those (cut) wires.
