Tamper springs closed correctly?
9427 is the keypad, the panel is a 9448/9448+
Why TWO 2.1 AH batteries? You would never fit them into the panel.
Ahh thinking about it a larger metal box 9449???
Still wondering about the TWO batteries, have you wired them back in correctly?
Series and Parallel will cause serious issues. Even blow up the panel.
More info please.
